海外TECH	DEV Community	Song search application built using Typesense.	https://dev.to/aviyel/song-search-application-built-using-typesense-19l7	Song search application built using Typesense Crafting search engines from absolute scratch which are typo tolerant effective and efficient is really very difficult A typographical error could cause a search to return nothing even if the requested item is in the database By obviating the need to develop a search engine Typesense could save a lot of time and effort Your users will also be able to use the search feature in your app effectively resulting in a positive user experience Typesense is an open source typo tolerant search engine for developers designed to cut down on the time it takes to find information quickly To learn more about typesense go to the following link What is Typesense This article will walk you through installing Typesense creating a new application from scratch preconfiguring the client and more This post will also show you how to construct a Typesense Collection Finally we ll start our app and initialize it then add an item to our collection and start searching Building a Song Search Application from scratch Typesense ConfigurationTypesense can be used by installing its prebuilt docker image which is already provided to us by Typesense or by using the Typesense cloud hosting solution which is the most straightforward way to get started To get started go to the Typesense cloud website and sign up with your Github account or use the docker method easily and directly We ll use the Docker method for the purposes of this tutorial To follow along with this tutorial go to the Typesense Dockerhub and download the prebuilt docker image then follow the instructions below docker pull typesense typesenseandmkdir tmp typesense datadocker run p v tmp data data typesense typesense data dir data api key songsearch enable cors listen port Building Search UIs from scratch Using the open source InstantSearch js library library or its React Vue and Angularjs as well as the Typesense InstantSearch Adapter you can create a plug and play full featured search interface with just a few lines of code Finally lets s actually build a search UI for our Application Step by step instructions for installingLet s begin with a basic template npx create instantsearch app typesense songsearch The name of the application or widget typesense songsearch InstantSearch template InstantSearch jsCreating a new InstantSearch app in typesense songsearch InstantSearch js version Application ID latency Search API key beffcdfaeaf Index name instant search Attributes to display Used to generate the default result template Attributes to display Used to filter the search interface Dynamic widgetsInstalling dependencies yarn install v info No lockfile found Resolving packages Fetching packages Linking dependencies Building fresh packages success Saved lockfile Done in s Created typesense songsearch at typesense songsearch Begin by typing cd typesense songsearch yarn start️Start building something awesome This is how your folder structure should look after you ve finished installing your Instantsearch app UI For the npx create instantsearch app command here are some setup suggestions Any of the web libraries supported by typesense can be used including InstantSearch js  React  Vue and Angular The default version of InstantSearch js can be used The application ID can be any string we ll be changing it later in the article Search API key any string later in the guide we ll replace this with the Typesense Search only API Key and Our index name is the name of the collection in Typesense and lastly leave the Displaying attributes as it is Next we ll need to install the Typesense InstantSearch adapter to use InstantSearch with a Typesense backend npm install typesense instantsearch adapter Installing Typesensenpm install typesenseWe re ready to create a Typesense collection Now that everything is installed and running we can create a Typesense collection index some documents in it and try searching for them Your package json file should look like this after you ve installed all of the necessary dependencies name typesense songsearch version private true main src app js scripts start parcel index html port build parcel build index html lint eslint lint fix npm run lint fix devDependencies babel eslint eslint eslint config algolia eslint config prettier eslint plugin import eslint plugin prettier parcel bundler prettier dependencies algoliasearch instantsearch js typesense typesense instantsearch adapter As you can see it s a very basic app with only two important files  app js and index html which contains the structure of our entire app In the index html file you can see an id We can use those ids to attach UI components such as a searchbox  results and facets if you want to include them as well as pagination widgets lt DOCTYPE html gt

pagination search start To use InstantSearch with a Typesense backend we ll need to install the Typesense InstantSearch adapter To do so simply open a terminal window and type the following command into it If you ve already installed it you can skip this step npm install save typesense instantsearch adapterFinally the project can be adjusted to use Typesense In the background we ve got our typesense instance up and running Open src app js and change the way InstantSearch is initialized to get InstantSearch js to use the Typesense adapter const searchClient algoliasearch latency

searchClient indexName songs Now we need to import our songs data so create a dataset folder and inside it create your own songs json file filling it with all of the necessary song information or download the songs dataset from here Finally your folder structure should look something like this Let s get to work on the data importing scripts We ll start by creating a file called loadData js and we will export and initialize the typesense client inside but before we do that we need to install a few packages lodash and fast json stringify npm i lodashandnpm i fast json stringifySo at the very top import all of the dependencies that this script requires to run as shown below loadData jsconst require lodash const fastJson require fast json stringify const fs require fs const readline require readline const Typesense require typesense After that Create a stringify based on the schema of the documents that need to be stringified loadData jsconst require lodash const fastJson require fast

relations filter r gt amazon asin streaming free streaming download for free purchase for download includes r type map r gt return type r type url r url resource Now create an asynchronous addSongsToTypesense function and copy the code exactly as it is shown below This function will simply index all of the songs into Typesense and if an error occurs during the process it will simply log an error async function addSongsToTypesense songs typesense songsCollection try const returnDataChunks await Promise all chunk songs Math ceil songs length CHUNK SIZE map songsChunk gt

Collection in Typesense is a set of related Documents that functions similarly to a table in a relational database We give a collection a name and describe the fields that will be indexed when a

addSongsToTypesense songs typesense songsCollection console log ALL songs INDEXED Finally type node loadData js into the terminal of that same project directory and you have successfully imported thousand songs documents into the search index Now you can start your application by typing npm start in the terminal of that project directory We need to fix the fact that the application functions perfectly but no information as well as data is displayed in it So to fix it go to our app js file and remove a few of the widgets that we don t need so the app js file should look something like this app jsconst instantsearch window import TypesenseInstantSearchAdapter from typesense instantsearch adapter const typesenseInstantsearchAdapter new TypesenseInstantSearchAdapter server apiKey songsearch nodes host localhost port protocol http additionalSearchParameters queryBy title primary artist name album name quering by const searchClient typesenseInstantsearchAdapter searchClient const search instantsearch searchClient indexName songs search addWidgets instantsearch widgets searchBox container searchbox instantsearch widgets hits container hits instantsearch widgets pagination container pagination search start Simply re run the application after you ve fixed it and your application should now look like this You can now build a search interface using any of the InstantSearch widgets and we ll be adding a template to present the data in a pleasing manner Simplycopy the template code below and add it inside the  hits widget present inside app js file templates item lt h gt attribute title lt h gt lt div gt by lt a style color FFF gt attribute primary artist name lt a gt lt div gt lt div gt Album lt a style color d gt attribute album name lt a gt lt div gt lt div class

application and your app should now look like this Simply add the following code above the  hits widgets inside the app js file to configure the hits per page or to configure to your own requirements instantsearch widgets configure hitsPerPage So now let s try to add the facets to do that we ll add an instant search widgets In the instantsearch library this is called refinementlist and finally we have to specify the container in our case let s call it a  genreFilter artistFilter and then the attribute we want to take in our case let s call it genres and primary artist name respectively So our final code should look like this app jsconst instantsearch window import TypesenseInstantSearchAdapter from typesense instantsearch adapter const typesenseInstantsearchAdapter new TypesenseInstantSearchAdapter server apiKey songsearch nodes host localhost port protocol http additionalSearchParameters queryBy title primary artist name album name quering by const searchClient

海外TECH	DEV Community	WebSocket vs Server-Sent events	https://dev.to/minompi/websocket-vs-server-sent-events-2b77	WebSocket vs Server Sent eventsUsually I have heard more times the term WebSocket than server sent events The reason could be that WebSocket is used more but not always is the ideal approach Sometimes Server sent events approach is better to solve problems and create good applications It s very important to understand differences limits and ideal cases for both to solve your problem with the right solution Sometimes we have a cognitive bias that doesn t allow us to take the right decision Cognitive bias is a systematic error in thinking that occurs when people are processing and interpreting information in the world around them and affects the decisions and judgments that they make Image from So for example if we have solved a problem using WebSocket next time with a similar problem we could think that again it s the right approach without considering the big picture all information about the problem to solve For that reason understanding deeply bot approaches can help us to reduce the cognitive bias and make the best decision Let s try to explain both approaches and their characteristics WebsocketIt s a computer communications protocol that provides full duplex communication channels over a single TCP connection Wikipedia The protocol was standardized in The WebSocket approach is used in many contexts and projects because has many benefits and pros in its favor Bidirectional communicationThe client and server can both send data to the other part The client creates a TCP connection to the server and keeps it open as long as needed Both server and client can close the connection easily whenever they want To exchange data there is a handshake process that verifies the communication and if it s all ok they can exchange data using the custom WebSocket protocol Image from AdvantagesBidirectional communication in real time connections can both send and receive data from the browser example chat Generally don t use XmlHttpRequest and headers are not sent every time so it reduces the expensive data loads being sent to the server Can transmit both binary data and UTF format LimitsWhen connections are terminated WebSocket doesn t automatically recover them you need to implement a reconnection system by yourself Browsers older than don t support WebSocket connections Some enterprise firewalls with packet inspection have trouble dealing with WebSocket Ideal casesChat both client and server exchange data to send and receive messagesMultiplayer gamesCollaborative editing codingSocial feedsSport updates…a lot more … Server Sent EventsIt s a server push technology enabling a client to receive automatic updates from a server via an HTTP connection It was born on September so it s been a while since it s available It provides a memory efficient implementation of XHR streaming Unlike a raw XHR connection which buffers the full received response until the connection is dropped an SSE connection can discard processed messages without accumulating all of them in memory Monodirectional communicationThe client sends a request to subscribe to a specific channel and the server will send event data into that request so only the server can send data and the client receive automatically those events in the same HTTP connection Image from AdvantagesTransported over simple HTTP instead of a custom protocolSimpler protocolBuilt in support for re connection and event idNo troubles with corporate firewalls doing packet inspection LimitsIt s limited to UTF and does not support binary data It s subject to limitation with regards to the maximum number of open connections This can be especially painful when opening various tabs as the limit is per browser and set to a very low number It s mono directionalIt doesn t have native browser support However there are available workaround with poly fill replicate an API in Javascript that simulates the SSE functionality to solve this issue All modern browsers support server sent events Firefox Google Chrome Opera Safari Microsoft Edge Ideal casesStock client updates the client receives updates from the server when a stock changes its valueTwitter feed updates the client receives a new tweet every time one is sentpush notifications ConclusionIn conclusion both approaches are valid and can be used to build specific software Websocket is more used and can be used also to develop an application that can use Server sent events Server sent Events have fewer ideal cases but for them it s very useful with less configuration and less time to create the updating system I have used both of them and no one is better than another it depends on the specific context and what you need at that moment Knowing WebSocket and Server sent events can help you in deciding which approach is better for every application	2022-04-29 08:25:37
海外TECH	DEV Community	Fullstack ecommerce site using Nextjs, Supabase, prisma and chatwoot.	https://dev.to/aviyel/fullstack-ecommerce-site-using-nextjs-supabase-prisma-and-chatwoot-2j8e	Fullstack ecommerce site using Nextjs Supabase prisma and chatwoot We will be building SuperbaseEcommerce fullstack application in this article tutorial This application is simply an online ecommerce shopping site where users can browse all of the products upload their own products and even purchase the products This functionality will be added in the next series of articles It is similar to an Amazon app but it is simpler because we will not implement any actual payment or shipping procedures Here s a live demonstration of the final version of the app This is how your app should look after you finish this tutorial Feel free to experiment with it to get a sense of all the features we will be implementing Live Demo gt So in this tutorial we ll learn how to build this full stack app with Next js the react framework NextAuth js for implementing passwordless and OAuth authentication Supabase for persisting app data into a PostgreSQL database and stashing media files and information and Prisma for making it simple to read and write data from and to the database from our app This article tutorial covers many topics and technical concepts necessary to build a modern full stack app even if this app is a simplified version of a more advanced ecommerce site like Amazon You should be able to use all of the technologies covered in this tutorial including react nextjs prisma supabase and others but most importantly you should be able to build any full stack app using those technologies You ll go at your own speed and intensity with us guiding you along the way After completing this guide the goal of this article is to provide you with the tools and techniques you ll need to build a similar app on your own To put it another way this tutorial will not only teach you how to use those technologies in great detail but it will also provide you with the proper mixture of principles and application to help you grasp all of the key concepts so that you can proudly build your own apps from scratch later part on this article Let s start with the react portion and build our application The first step is to install Node js if it isn t already on your computer So go to the official Node js website and download the most recent version Node js is required to use the node package manager abbreviated as npm Now launch your preferred code editor and navigate to the folder For this article tutorial we ll be using the VScode code editor Setting up SupabaseEcommerce project There is a Github repository dedicated to this project which consists of three branches Clone the SupabaseEcommerce starter branch to get started The Main branch contains the entire final source code of the application so clone the SupabaseEcommerce starter branch if you want to follow along with this tutorial git clone branch SupabaseEcommerce starter After that head over to the cloned directory and install the dependencies before starting the Next js development server cd SupabaseEcommerceyarn add allyarn devYou can now check if everything is working properly by going to http localhost and editing pages index js then viewing the updated result in your browser For more information on how to use create next app you can review the create next app documentation It usually only takes a few minutes to get everything set up So for this project we will be using yarn to add packages to a project which will install and configure everything for us so that we can get started right away with an excellent starter template It s time to start our development server so head over to that SupabaseEcommerce folder and type yarn add all and then yarn dev and the browser will instantly open our starter template Next js appplication Your application s folder structure should look something like this So you might be curious about the source of the content Remember that all of our source code is housed in the pages folder and react next will inject it into the root div element Let s take a look at our pages folder which contains some javascript files and one API folder Before we dive any further lets actually create a landing page for our site so before we even begin first you need to install framer motion library Let s dive in and create a beautiful looking UI for our E commerce application before we start on the backend integration part Let s start by making a landing page for the app and then move on to making a product page for it So inside the components folder create a Layout component and add the following code to it This component is simply a basic layout for our application that includes a navigation bar amp menus as well as the functionality to display our application s registration login modal components Layout jsimport Fragment useState from react

you ve successfully created a landing page for the application let s move on to the core of the matter creating the product section of the application So Now let s look at the  app js file app jsimport styles globals css import Toaster from react hot toast function MyApp Component pageProps return lt gt lt Component pageProps gt lt Toaster gt lt gt export default MyApp The App component is used by Next js to create pages You can control the page initialization by simply overriding it It allows you to do amazing things like Persisting layout across page changes Keeping state while navigating pages Custom error handling using componentDidCatch Inject additional data into pages and Add global styles CSS are just a few of the great things you can accomplish with it In the above app js code the Component parameter represents the active page when you switch routes Component will change to the new page As a result the page will receive any props you pass to Component Meanwhile pageProps is an empty object that contains the initial props that were preloaded for your page by one of the data fetching methods Now inside the pages folder create a new page called products js and import the Layout and Grid components then import the data json file as products and make the following changes to it pages products jsimport Layout from components Layout import Grid from components Grid import products from data json export default function Products return lt Layout gt lt div className mt p gt lt Grid products products gt lt div gt lt Layout gt Database ConfigurationsBefore jumping directly on our application we ll be utilizing the power of Supabase to create a PostgreSQL database the Prisma schema to define the app data model and Next js to connect those two together So let s get started building our database Supabase ConfigurartionCreating a PostgreSQL database in Supabase is as simple as starting a new project Head over to supabase com and Sign in to your account After you ve successfully signed in you should see something similar to this Now select New project button Fill in your project s required details and again click Create Project button and wait for the new database to load After the supabase configured the project your dashboard should look something similar to this Creating a connection URLFollow the steps outlined below to retrieve your database connection URL after your database has been successfully created We ll need it to use Prisma in our Next js app to query and create data Step Head over to the Settings tab Located at the left side Step Click the Database tab in the sidebar Located on the left side Step Head over to the bottom of the page to find the Connection string section then select Nodejs and copy the URL Initializing PrismaPrisma is a next generation ORM that can be used in Node js and TypeScript applications to access a database W eare going to use prisma fo our application because it includes all of the code we need to run our queries It will save us a lot of time and keep us from having to write a bunch of boilerplate codes Installing prisma Prisma CLI installationThe Prisma command line interface CLI is the primary command line interface for interacting with your Prisma project It can create new project assets generate Prisma Client and analyze existing database structures via introspection to create your application models automatically npm i prisma Initialize prismaOnce you ve installed the Prisma CLI run the following command to get Prisma started in your Next js application It will then create a prisma directory and the schema prisma file within it inside your particular project folder so inside it we will be adding all the configuration for our application npx prisma init prisma schemagenerator client provider prisma client js datasource db provider postgresql url env DATABASE URL Note schema prisma uses Prisma Schema Language PSL Prisma client js the Prisma JavaScript client is the configured client represented by the generator block generator client provider prisma client js Next one is the the provider property of this block represents the type of database we want to use and the connection url represents how Prisma connects to it datasource db provider postgresql url env DATABASE URL Environment variableUsing environment variables in the schema allows you to keep secrets out of the schema file which in turn improves the portability of the schema by allowing you to use it in different environments Environment variables is created automatically after we fire the npx prisma init command Note Prisma supports the native connection string format for PostgreSQL MySQL SQLite SQL Server MongoDB Preview and CockroachDB Preview DATABASE URL postgresql test test localhost test schema foo As you can see there is an DATABASE URL variable with a dummy connection URL in this environment variable env So replace this value with the connection string you obtained from Supabase DATABASE URL postgresql postgres YOUR PASSWORD db bboujxbwamqvgypibdkh supabase co postgres Prisma schemas and modelsWe can begin working on our application s data models now that database is finally connected to your Next js In Prisma our application models should be defined within the Prisma schema using the Prisma models These models represent the entities of our application and are defined by the model blocks in the schema prisma file Each block contains several fields that represent the data for each entity So let s begin by creating the Product model which will define the data schema for our products properties Defining modelsModels represent the entities of your application domain Models are represented by model blocks and define a number of fields In this data model Product is the model prisma schemagenerator client provider prisma client js datasource db provider postgresql url env DATABASE URL model Product id String id default cuid image String title String description String status String price Float authenticity Int returnPolicy Int warranty Int createdAt DateTime default now updatedAt DateTime updatedAt Each field as shown in our Product model has at least a name and its type To learn more about the Scalar types and Prisma schema refrences visit the following links Data modelPrisma schemaPrisma schema reference Generate Prisma ClientAfter designning Prisma model we can begin generating our Prisma Client We ll need to use Prisma s JavaScript library later in the article to interact with our data from within our Next js app without having to write all of the SQL queries ourselves But there s more to it Prisma Client is in fact an auto generated type safe API designed specifically for our application which will gives us the JavaScript code we need to run queries on our data Step Installing prisma client npm install prisma clientstep Generating Prisma client npx prisma generate The prisma client npm packageThe prisma client npm package consists of two key parts The prisma client module itself which only changes when you re install the packageThe prisma client folder which is the default location for the unique Prisma Client generated from your schema prisma client index d ts exports prisma clientFinally after you have done that inside your node modules folder you should now find the generated Prisma Client code Note You need to re run the prisma generate command after every change that s made to your Prisma schema to update the generated Prisma Client code Here is a graphical illustration of the typical workflow for the Prisma Client generation Note also that prisma generate is automatically invoked when you re installing the prisma client npm package The Prisma Client is generated from the Prisma schema and is unique to your project Each time you change the schema and run prisma generate the client code changes itself Pruning in Node js package managers has no effect on the prisma folder Creating a table in SupabaseIf you look at your database in Supabase you ll notice there is no table inside it It s because we haven t yet created the Product table The Prisma model we defined in our schema prisma file has not yet been reflected in our database As a result we must manually push changes to our data model to our database Pushing the data modelPrisma makes it really very easy to synchonize the schema with our database So to do that follow the command listed below npx prisma db pushThis command is only good for prototyping on the schemas locally OR npx prisma migrate devThis method npx prisma migrate dev will be used in this article because it is very useful in that it allows us to directly sync our Prisma schema with our database while also allowing us to easily track the changes that we make So to begin using Prisma Migrate enter the following command into the command prompt and after that enter a name for this first migration when prompted After you have completed this process successfully prisma will automatically generate SQL database migration files and you should be able to see the SQL which should look something like this if you look inside the prisma folder CreateTableCREATE TABLE Product id TEXT NOT NULL image TEXT title TEXT NOT NULL description TEXT NOT NULL status TEXT NOT NULL price DOUBLE PRECISION NOT NULL authenticity INTEGER returnPolicy INTEGER warranty INTEGER createdAt TIMESTAMP NOT NULL DEFAULT CURRENT TIMESTAMP updatedAt TIMESTAMP NOT NULL CONSTRAINT Product pkey PRIMARY KEY id Finally check the Supabase dashboard to see if everything has been successfully synced Prisma StudioPrisma Studio is a visual interface to the data residing inside your database where you can use to quickly visualize and manipulate the data The cool thing about it is that it runs in entirely on your browser and you don t need to set up any connections because it s already comes with the prisma package Not only that from the studio you can quickly open all of your application s models and interact with them directly via studio itself Note There is also desktop application available to download Launching Prisma StudioLaunching the prisma studio is really very easy Literally all you have to do is run the following command from a Prisma project npx prisma studioNow open your browser and head over to http localhost You should be able to see the single table that we ve created previously if you ve followed all of the steps correctly Manually adding the recordsLets manually add some records and save the changes that we made Finally lets create a functionality to access that data from within our Next js app where we can create new records update existing ones and delete old ones Interacting with data using Next jsYou should see some demo datas if you look at the Product page of your application Now open the file pages products js file which represents our app s product page pages products jsimport Layout from

array export default Grid Now we want to retrieve data from our database and we ll do so using Server Side Rendering SSR The ability of an application to convert HTML files on the server into a fully rendered HTML page for the client is known as server side rendering SSR The web browser sends a request for information to the server which responds immediately by sending the client a fully rendered page So in order to use Server Side Rendering SSR with Next js we must export an asynchronous function getServerSideProps from within the file which exports the page where we want to render out our data The data returned by the getServerSideProps function will then be used by Next js to pre render our page on each individual request Let s get started and export this function from our applicartion s Prodcuts page pages products jsimport Layout from components Layout import Grid from components Grid import products from products json export async function getServerSideProps return

product details and informations API endpointLet s actually create a API endpoint that will actually create a new record on our database via addProduct function const createProduct gt null But first within our Next js application project let s create an API endpoint to handle our POST request for creating new records Next js provides a file based API routing so any file in the pages api folder is mapped to api and treated as an API endpoint rather than a page They re only server side bundles so they won t add to the size of your client side bundle So create a file name called products js inside the pages api folder and inside it create a request handler fucntion like shown below export default async function handler req res Handling POST request for productsBefore we go any further use req method to check the HTTP method of the request inside that request handler function After that return a status code to the client becasue we are not handlling any kind of HTTP method pages api products jsexport default async function handler req res if req method POST TODO else res setHeader Allow POST res status json message HTTP method req method is not supported Adding new records with Prisma ClientNow lets use Prisma Client to create a new Product record in the database using the data from the current HTTP request pages api products jsexport default async function handler req res if req method POST const image title description status price authenticity returnPolicy warranty req body else res setHeader Allow POST res status json message HTTP method req method is not supported After that lets actually initialize Prisma and call the create function that prisma provides import PrismaClient from prisma client const prisma new PrismaClient export default async function handler req res if req method POST const image title description status price authenticity returnPolicy warranty req body const home await prisma product create data image title description status price authenticity returnPolicy warranty else res setHeader Allow POST res status json message HTTP method req method is not supported Finally lets add some try catch block to Handle the error pages api products jsimport PrismaClient from prisma client const prisma new PrismaClient export default async function handler req res if req method POST try const image title description status price authenticity returnPolicy warranty req body const product await prisma product create data image title description status price authenticity returnPolicy warranty res status json product catch e res status json message Something went wrong else res setHeader Allow POST res status json message HTTP method req method is not supported Now that we ve created our API let s call the API endpoint To do so open the addProduct js file in the pages folder and make the following changes to the code but first we ll need to install the axios package so do that first npm i axiosORyarn add axios pages addProducts jsimport Layout from components Layout import ProductList from components ProductList const addProducts gt const createProduct gt data gt axios post api products data return lt Layout gt lt div className max w screen xl mx auto flex col gt lt h className text xl font medium text gray justify center gt Add your Products lt h gt lt div className mt gt lt ProductList buttonText Add Product redirectPath products onSubmit createProduct gt lt div gt lt div gt lt Layout gt export default addProducts Now lets re run the server again After that head over to your browser and go to the http localhost addProducts route and fill out all the product information and Submit it It will automatically redirect you to the products page and you should be able to see the product that you just added Pre rendering the pagesWe ve used the getServerSideProps function to pre render the product of our app using Server Side Rendering SSR Next js on the other hand comes with a built in pre rendering method called Static Generation SSG When a page uses Static Generation the HTML for that page is generated during the build process That means that when you run next build in production the page HTML is generated Each request will then be served with the same HTML A CDN can cache it You can statically generate pages with or without data using Next js We can use different pre rendering techniques on our applications when we use a framework like Next js For something more simple and non dynamic we can use static site generation SSG For dynamic content and more complex pages we can use server side rendering SSR Dynamic Routing with SSGWe can still statically generate pages with SSG after fetching some external data during the build process even if SSG generates HTML at build time learn more about static generation and dynamic routing Let s get data at build time by exporting an async function called getStaticProps from the pages we want to statically generate For Example posts will be populated at build time by getStaticProps function Blog posts return lt ul gt posts map post gt lt li gt post title lt li gt lt ul gt This function gets called at build time on server side It won t be called on client side so you can even do direct database queries export async function getStaticProps Call an external API endpoint to get posts You can use any data fetching library const res await fetch https posts const posts await res json By returning props posts the Blog component will receive posts as a prop at build time return props posts export default Blog Let s put Static Generation SSG to work in our application The pages that render each individual Product listing are the ones that we ll statically generate at the build time However because product listings are generated through the users we could end up with massive amount of pages As a result we won t be able to define those routes using predefined paths Otherwise we ll end up with a slew of useless files cluttering up our project We can easily create dynamic routes in Next js We just need to add brackets to a page s filename id js to create a dynamic route However in our project we will place that in the Products folder As a result any route s ids will be matched with their specific id value and the id value will be available inside the React component that renders the associated page Now go to the pages folder and make a new folder called products then make a new file called id js inside it And finally paste the following code inside that file pages products id jsximport Image from

Layout gt export default ListedProducts Now let s actually provide the lists of paths of the pages that we want to statically generate and let s actually fetch some data and match it with the numbers of paths To do so we must provide the paths to Next js that we want to pre render at build time This function should return all the paths of the pages to pre render at build time along with the corresponding id value in the returned object s params property So for that we ll be using Prisma to retrieve the IDs for all of the products residing on our database pages products id jsximport Image

return paths products map product gt params id product id fallback false export default ListedProducts The getStaticProps function must now be implemented So let s get started As you can see the first thing we do is use the Prisma findUnique function with the id retrieved from the query params object to get the data of the requested route Then if the corresponding home is found in the database we return it to the ListedProducts React component as a prop If the requested products cannot be found we return an object to tell Next js to redirect the user to our app s products page pages products

browser and open the application Implementing Incremental Static Generation ISR If you try to access a page for a new product listing in production you ll get a error page instead To see this in action build your app and run it as you would in production because getStaticProps runs on every request in development So we have different behavior in development that differs from what we would see in production To serve a production build of your application simply fire up the following command but make sure to stop the server first yarn buildyarn startThe main reason for the page is that we used Static Generation to define the routes products id js and we only generated pages for the products that were in our database at the time In other words after this build process none of the products our users create will generate a new page That is why we have a page instead because the page simply does not exist at all To fix this we ll need to define a fallback that will allow us to continue building pages lazily at runtime pages products id jsimport Image from next image import Layout from components Layout import PrismaClient from prisma client Instantiate Prisma Clientconst

because we haven t yet implemented aby media storage We ll use Supabase Storage a fantastic service from Supabase to store and use media files in our project Creating a bucket in supabaseBuckets are distinct containers for files and folders It is like a super folders Generally you would create distinct buckets for different Security and Access Rules For example you might keep all public files in a public bucket and other files that require logged in access in a restricted bucket To create a bucket in Supabase first navigate to the storage section of the dashboard After that select Create Bucket button Next give the bucket a name for now we ll call it supabase ecommerce and remember to make it public and click on that Create Button button Manually uploading image on databaseStep Head over to the supabase Storage and upload the products images Step Select the product image and copy the image urlStep Open up the Prisma Studio by typing npx prisma studio inside the command line terminal Step Now paste all of the image urls you copied in Step inside the image row Go back to the application and refresh the page now that you ve added all of the image urls You may encounter the error shown below Copy the hostname of your file URL and paste it into the images domains config in the next config js file to fix the error module exports reactStrictMode true images domains ezkjatblqzjynrebjkpq supabase co After that restart the server and you should see images Security RulesWe must define some security rules to be able to deal with our image files inside our bucket using the Supabase API So add the security rules from our Supabase dashboard Step Head over to the Storage section and go to the Policies section Step Create a New Policy Step Select Get started quickly Step Use Allow access to JPG images in a public folder to anonymous users this template Step Give the Policy Name select all the Operation and give bucket id and Hit Review Step Review the policy and save it Step Finally you ve successfully created a Storage Policy Upload a file from applicationLet s keep going and add the ability for our application to upload and store our products

your application The first one is base arraybuffer which encodes and decodes base to and from ArrayBuffers and another package called nanoid which is a very tiny secure URL friendly unique string ID generator for JavaScript yarn add nanoid base arraybufferReturn to our API endpoint and upload a file to our bucket using the Supabase Client Obtain the image data from the request s body and verify that it is not empty then inspect the image data for Base encoding After that save the file to your Supbase storage bucket With the SUPABASE STORAGE BUCKET env you must provide the storage bucket name the file path and the decoded Base data as well as the contentType Once the image has been successfully uploaded we can generate its public URL and return it to the client who initiated the HTTP
