海外TECH	DEV Community	Parsing Parquet stored in S3 with Go	https://dev.to/aws-builders/parsing-parquet-stored-in-s3-with-go-2k7p	Parsing Parquet stored in S with GoI know it s but you can t get away from processing files In a world of Events APIs and Sockets files still exist as a medium for moving data around And a very common one at that In recent years I ve found myself dealing with Apache Parquet format files And more specifically I often end up dealing with them coming out of AWS S If you are a consumer at all of the AWS DMS product when replicating you will find out that parquet format is a great way to deal with your data as its designed for efficient storage and retrieval There aren t too many options for parsing a parquet file with Golang but I ve find a library I really enjoy and the article below will describe how to make the best use of it As always here is the link to the Github Repository if you want to skip ahead What is Apache ParquetApache Parquet is an open source column oriented data file format designed for efficient data storage and retrieval It provides efficient data compression and encoding schemes with enhanced performance to handle complex data in bulk Parquet is available in multiple languages including Java C Python etc… Downloading the Parquet FileFor working with S I really like the Golang library called smanager Here is the SDK documentation What I like about it is that is a higher level abstraction on top of the normal S library For instance to download a file from a bucket you simply do something like thisdownloader smanager NewDownloader sess err downloader DownloadWithContext ctx file amp s GetObjectInput Bucket aws String bucket Key aws String key The downloader will put the file in the path you specify in the DownloadWithContext method in the “file parameter It s just a string Parsing File with GolangParsing an Apache parquet file with Golang will seem super family to other interface based unmarshalling like DyanamoDB as well as JSON For similarities with DDB you can see how to do this in the referenced articleThe parse function looks like thisfunc ParseFile fileName string ParquetUser error fr err floor NewFileReader fileName var fileContent ParquetUser if err nil return nil err for fr Next rec amp ParquetUser if err fr Scan rec err nil continue along is it s just a malformed row if errors Is err ErrIllegalRow continue return nil err fileContent append fileContent rec return fileContent nil First off notice that I open a FileReader from the parquet go library From there I create a slice for holding the output of what s being unmarshalled Then we loop and scan And for each call to Scan the unmarshall method that implements the parquet go interface is called That method looks like thisfunc r ParquetUser UnmarshalParquet obj interfaces UnmarshalObject error id err obj GetField id Int if err nil return errors New fmt Sprintf error unmarshalling row on field id firstName err obj GetField firstName ByteArray if err nil return errors New fmt Sprintf error unmarshalling row on field firstName lastName err obj GetField lastName ByteArray if err nil return errors New fmt Sprintf error unmarshalling row on field lastName role err obj GetField role ByteArray if err nil return errors New fmt Sprintf error unmarshalling row on field role note this is a time Time but comes across as an Int lastUpdated err obj GetField lastUpdated Int if err nil return errors New fmt Sprintf error unmarshalling row on field lastUpdated parsed time UnixMicro lastUpdated if err nil log WithFields log Fields err err Error error parsing time return errors New fmt Sprintf lastUpdated is not in the right format r Id int id r FirstName string firstName r LastName string lastName r Role string role r LastUpdated parsed return nil Really not too much going on up there outside of fetching fields and then putting them into the structs fields The one main thing to point out that is a “gotcha is that the LastUpdated field is a time Time The parquet go library treats time as an Int Note this line for converting what comes out of the library into a time Timeparsed time UnixMicro lastUpdated Running the ProgramFrom there it s just a matter of putting it all together Here s the body of mainfunc main file err DownloadFile context TODO sess bucket key if err nil log WithFields log Fields err err Error error downloading the file contents err ParseFile file if err nil log WithFields log Fields err err Error error parsing the file err DeleteFile file if err nil log WithFields log Fields err err Error error deleting the file for c range contents log WithFields log Fields record c Debug printing the record In a nutshell … Download the file Parse the file Delete the file Loop and print output Helpful TipsI m using VSCode a lot more these days and I m sort of weaning myself off of Goland So you ll find a launch json file in the vscode directory There you can set the environment variables you need to run the programViewing parquet files is really a pain I ve found There are few tools that I ve liked Online viewers get in the way of my workflow BUT I found this VSCode plugin to be FANTASTIC Here is the link to the marketplace Wrapping UpHopefully you found this helpful Like I mentioned in the beginning files aren t going away as a data medium And Apache s Parquet is an excellent one when you deal with larger datasets and it ll be one of the options you can choose when replicating with DMS as the output I continue to just love Golang s simplicity and performance as well as the development experience The parquet go library has a few quirks but overall star rating for me	2023-03-16 12:39:04
海外TECH	DEV Community	Responsive Website using CSS and JS | Full of Animations	https://dev.to/themodernweb/responsive-website-using-css-and-js-full-of-animations-3ico	Responsive Website using CSS and JS Full of AnimationsIn this article you will learn to create this awesome fully responsive travel website using only HTML CSS and Javascript It is fully responsive and has animation on scroll smooth scrolling tile animated background images slider and a lot of stuff You can download the code So without wasting time let s see how to code this Video TutorialVideo tutorial if you like to watch a video and follow along Let s goSo to start coding or following this article First you need to setup the folder For this project we will use Google Fonts AOS library for animations and Fontawesome for icons So you can either add CDNs manually or you can download the start files from this repoRepo also includes all the imagesSo I hope you have the starting files now Let s start with our navbar first NavbarTo create navbar we need to make a header and that header will contain the navbar as well as the main section index html lt header gt lt nav class navbar gt lt ul class links container gt lt li class link item gt lt a href travel gt Travel lt a gt lt li gt lt li class link item gt lt a href explore section gt Explore lt a gt lt li gt lt li class link item gt lt a href hero section gt lt img src img logo png class logo alt gt lt a gt lt li gt lt li class link item gt lt a href services gt Services lt a gt lt li gt lt li class link item gt lt a href booknow gt Book Now lt a gt lt li gt lt ul gt lt nav gt lt header gt The value of href of links are id of the sections that we will create next Giving ids as a link will take you to that section after clicking on the link But to add a smooth scrolling effect to the navbar links Make sure you give scroll behaviour to the html style csshtml scroll behavior smooth body font family Poppins sans serif background overflow x hidden navbar position fixed top left z index width height px padding px vw navbar bg background links container display flex align items center justify content center list style none logo height px margin top px link item margin px transition s link item a color fff text decoration none padding px link item hover transform scale Output Hero SectionNow to create hero section we will use main tag inside header after nav index html lt main class hero section id hero section gt lt div class hero section content data aos fade up gt lt h class hero section title gt wonderful experience lt h gt lt p class hero section sub heading gt Lorem ipsum dolor sit amet consectetur adipiscing elit lt p gt lt div gt lt scroll down img gt lt img src img down arrow png class scroll down icon alt scroll down indicator gt lt main gt If you notice i used data aos attribute in code This attribute is custom provided by AOS library to add sroll animations In this case I am adding fade up effect To make it work though you have to put AOS init in app js along with the CDNs provided in the github repo Make sure you download the repo to start style css hero section width height vh position relative display flex justify

center text transform capitalize margin px font size px scroll down icon position absolute bottom left transform translateX width px animation down ease s infinite keyframes down from bottom to bottom OutputNow the best part of this whole website the background image slider Image SliderTo create Image Slider first we will create a img below the content and then above img we will create divs of background black in a grid Those divs will cover whole image when needed So basically we will show those divs and hide them and in between we will change the background image using JS For this make background div inside main before hero section content index html lt div class background gt lt img src img img png class background image alt hero section image gt lt grid gt lt div class grid slider gt lt div class grid item hide gt lt div gt lt div class grid item hide gt lt div gt lt div class grid item hide gt lt div gt lt div class grid item hide gt lt div gt lt div class grid item hide gt lt

height object fit cover z index background before background after content position absolute left width height background before top left background var gradient top background after bottom background var gradient bottom grid slider width height display grid grid template columns repeat fr grid template rows repeat fr grid item width height background opacity transition s grid item hide opacity If you see above code I used before and after to create some linear gradients over the image to create the depth The variables I used are in the CSS file of repo OutputNow to make this slider working Just add this simple JS code inside app js file header slider images arrayconst sliderImgs img png img png img png img png img png img png let sliderImage document querySelector background image let sliderGrids document querySelectorAll grid item let currentImage setInterval gt changeSliderImage const changeSliderImage gt sliderGrids map gridItem index gt setTimeout gt gridItem classList remove hide setTimeout gt if index sliderGrids length if currentImage gt sliderImgs length currentImage else currentImage sliderImage src img sliderImgs currentImage sliderGrids map item i gt setTimeout gt item classList add hide i index After adding this the slider will work In above code we are basically using timeout to hide and show the divs and in between changing the src of the image Output Explore SectionTo create next section which is explore section Its actually simple Just add this in index html file index html lt section class explore section id explore section gt lt h class section

海外TECH	DEV Community	refine vs Blitz.js	https://dev.to/refine/refine-vs-blitzjs-18h2	refine vs Blitz jsAuthor Madars BišsReact is a popular library for creating dynamic and interactive user interfaces Many frameworks have emerged from React to avoid the repetitive process of creating CRUD operations and other features for full stack applications In this article we will review two common solutions refine and Blitz By providing an advanced set of tools and features both aim to speed up and simplify the process of developing React apps We will take a closer look at how to set both up what are their internal builds how they handle the data sources how to implement the CRUD functionality add authentication and how to deploy them to production About frameworks refinerefine is a React based framework that is specifically designed to speed up the creation of data intensive applications It is an open source project meaning everyone can access and contribute the code By its core nature it is a headless framework that is based on a collection of hooks components and providers The core is fully decoupled from the UI and business logic meaning users have a fully flexible environment The refine framework was created in and has witnessed rapid growth and attracted an active community around it since then As of the time of the writing the framework has already reached around K GitHub stars BlitzBlitz is is a full stack web framework built on top of NextJS which means it preserves many of the core features like server side rendering static site generation and automatic code splitting Furthermore it is the NextJS toolkit that provides the necessary pieces to create feature rich applications adding features like authentication a type safe API layer and many more Blitz is also an open source project that allows users to access the code and allows to contribute Their community has generated a lot of impact as well and has grown rapidly over time since the creation in Installation guide refinerefine comes with the project starter tool which allows users to set up a fully working environment in minutes Run the command npm create refine app latest crud refine That will start the CLI wizard that will ask you to configure the project For the purpose of this tutorial pick the values as shown below The installation process should not take more than a minute Once it s done change the working directory to the newly created project by cd crud refine and run npm run dev to start up the developer server That should automatically open up a new browser window If it s not navigate to localhost manually and you will be presented with the refine welcome screen BlitzTo set up the Blitz app the user must first install the Blitz CLI You can do this by executing the command npm install g blitz or yarn global add blitz in your terminal Next run the command blitz new crud blitz This will start the terminal CLI wizard asking you to configure the project For the purpose of this tutorial pick the values as shown below After that change the working directory to the newly created project by running cd crud blitz and start the development server by running blitz dev Finally open your browser and navigate to localhost This should present you with a Blitz welcome screen Internal structure refinerefine file structure is as simple as it gets and they provide users with all the flexibility they would want to build upon The main building block for the whole app is the src folder It comes with the App tsx file with the following code import Refine from refinedev core import notificationProvider from refinedev antd import refinedev antd dist reset css import useAuth from auth auth react import routerBindings UnsavedChangesNotifier from refinedev react router v import dataProvider from refinedev simple rest import axios from axios import BrowserRouter from react router dom function App const isLoading user logout getIdTokenClaims useAuth if isLoading return lt span gt loading lt span gt const authProvider AuthBindings login async gt return success true logout async gt logout returnTo window location origin return success true onError async error gt console error error return error check async gt try const token await getIdTokenClaims if token axios defaults headers common Authorization Bearer token raw return authenticated true else return authenticated false error new Error Token not found redirectTo login logout true catch error any return authenticated false error new Error error redirectTo login logout true getPermissions async gt null getIdentity async gt if user return user avatar user picture return null return lt Refine dataProvider dataProvider notificationProvider notificationProvider Layout Layout ReadyPage ReadyPage catchAll lt ErrorComponent gt routerProvider routerProvider authProvider authProvider LoginPage Login gt export default App First the main Refine component and the necessary helper components like Layout ReadyPage and ErrorComponent are imported Then the style sheet file providers for data and router and auth components are imported In the App function first the auth logic is handled and then in the render block all of the imported helper components and providers are passed to the main Refine component as props To display the result on the screen all of the exported content from App tsx is imported and rendered to the DOM in the index tsx file import React from react import createRoot from react dom client import AuthProvider from auth auth react import reportWebVitals from reportWebVitals import App from App const container document getElementById root as HTMLElement const root createRoot container root render lt React StrictMode gt lt AuthProvider domain your auth domain address clientId your auth clientId redirectUri window location origin gt lt App gt lt AuthProvider gt lt React StrictMode gt Notice that the App component is wrapped into AuthProvider so that the authentication could be accessed throughout the whole app BlitzBlitz offers a more complicated framework like file structure where there are already pre defined ways how to handle and separate common concepts related to full stack applications The file structure looks as follows ├ーsrc │├ーauth ││├ーcomponents │││├ーLoginForm tsx│││└ーSignupForm tsx││├ーmutations │││├ーchangePassword ts│││├ーforgotPassword test ts│││├ーforgotPassword ts│││├ーlogin ts│││├ーlogout ts│││├ーresetPassword test ts│││├ーresetPassword ts│││└ーsignup ts││└ーvalidations ts│├ーcore ││├ーcomponents │││├ーForm tsx│││└ーLabeledTextField tsx││└ーlayouts ││└ーLayout tsx│├ーusers ││├ーhooks │││└ーuseCurrentUser ts││└ーqueries ││└ーgetCurrentUser ts│├ーpages ││├ーapi │││└ーrpc │││└ー blitz ts││├ーauth │││├ーforgot password tsx│││├ーlogin tsx│││└ーsignup tsx││├ー app tsx││├ー document tsx││├ー tsx││└ーindex tsx│├ーblitz client ts│└ーblitz server ts├ーdb │├ーmigrations │├ーindex ts│├ーschema prisma│└ーseeds ts├ーintegrations ├ーpublic │├ーfavicon ico │└ーlogo png├ーtest └ーsetup ts └ーutils tsxThe project structure is divided into multiple main blocks src db integrations public and test The core app code is featured in src which is further divided in auth consisting of the components and mutations for authentication core for form and layout components users for hooks and queries to handle the users and pages where all the new API and routes would be created The db folder includes all the necessary configuration schema and migration files for the database of your project If you use some third party libraries or code it s a great practice to separate them from the rest of the code Blitz has reserved the integrations folder for that purpose The public folder is for all the media assets and files that are served statically from the app s root URL There is also a dedicated test folder for tests that comes with setup and utility files to help you get started Data providers refinerefine comes with a fake data provider that is perfect for testing or creating some pages where you would need some placeholder data It is a simple REST API endpoint that contains sample data about users posts products categories etc and can be accessed via api fake rest refine dev If we click on any of the routes in the user interface we can see that each of them contains JSON data For example the products endpoint holds samples in the following format In order to use the data provider in the refine project the user needs to pass it to the Refine component in App tsx like this lt Refine dataProvider dataProvider gt If you followed the instructions for the installation wizard it should already be set up by refine automatically BlitzBlitz framework does not come with its own data provider but the great thing is that during the installation it configures the SQLite database which is more than enough for testing and experimentation The database configuration is available in the schema prisma file You will find it in the db folder in the app root It includes the database configuration and models used in the app datasource db provider sqlite url env DATABASE URL generator client provider prisma client js model User id Int id default autoincrement createdAt DateTime default now name String email String unique Another great thing is that with Blitz you can run blitz prisma studio to open the web interface in the browser and see all the data in your database If the UI does not open automatically navigate to localhost Authentication refineCreate a new free Auth account and log in Create a new web application It will give you domain client ID and secret ID information Scroll down and add localhost to the allowed URLs list Next switch back to your code editor and create a new file env in your project root add the variables REACT APP AUTH DOMAIN and REACT APP AUTH CLIENT ID and assign the values from the Auth dashboard Next edit the index tsx file in the src folder so it now looks like this import React from react import createRoot from react dom client import AuthProvider from auth auth react import App from App const container document getElementById root as HTMLElement const root createRoot container root render lt React StrictMode gt lt AuthProvider domain process env REACT APP AUTH DOMAIN as string clientId process env REACT APP AUTH CLIENT ID as string redirectUri window location origin gt lt App gt lt AuthProvider gt lt React StrictMode gt Now reset the developer server by pressing Ctrl C on your keyboard and run the command npm run dev to start it again This way the new environment values will take effect Now open your browser and navigate to localhost and you should be presented with the login screen BlitzThe great thing about Blitz is it already has the authentication views for signup and login It has also configured the database for it so you don t have to worry about creating separate models and running migrations for that The signup page should be available at localhost auth signup The login page should be available at localhost auth login Create a new account and sign up so we have a user record in the SQLite database and you can log in to access the pages we will build further Creating pages refineCreating new pages in refine is really simple thanks to its built in command create resource Since it s targeted at CRUD apps the user is allowed to choose what type of pages to generate via flags list create edit and show To get an overall insight into how the new pages are created in refine we will first create a page that lists the content Run the command npm run refine create resource products actions list in your terminal Navigate back to your project file tree and you will notice that a new folder pages was created Inside it there is a route specific folder products that includes files index ts and list tsx Open up the list tsx file and you will notice refine has even designed the Inferencer component that will automatically help you to design the views for resources based on the data structure import IResourceComponentsProps GetListResponse from pankod refine core import AntdInferencer from pankod refine inferencer antd export const ProductsList React FC lt IResourceComponentsProps lt GetListResponse lt gt gt gt gt return lt AntdInferencer gt Also notice the newly created list page was automatically imported and passed in as resource prop in the Refine component in App tsx lt Refine dataProvider dataProvider notificationProvider notificationProvider Layout Layout ReadyPage ReadyPage catchAll lt ErrorComponent gt routerProvider routerProvider authProvider authProvider LoginPage Login resources name products list ProductsList gt Now open your browser and navigate to localhost products You should be presented with the page that lists data from the products route from the refine s built in data provider BlitzBlitz does not come with the Inferencer component that would create a default view to display the data so we will create a custom page If you have previously worked with NextJS you will notice that the page system is the same For a new page you need to create a new tsx file inside the pages folder and it will become a new route To test it out create a new file greet tsx and include the following code const Greet gt return lt div gt lt h gt Hello from Blitz lt h gt lt p gt This is a custom Greetings page lt p gt lt div gt export default Greet Now open your browser and navigate to localhost greet and you should be presented with the rendered content of the newly created page CRUD functionality refinerefine has thought out how to make the CRUD operations as easy as possible Run the command npm run refine create resource posts This will create a new page for the posts route from the data provider but since we did not provide any flags of what specific operations to support all of the CRUD operations will be available This means that after running the command refine created a new folder inside pages called posts and populated it with files index ts list tsx create tsx edit tsx and show tsx Now open up your browser and navigate to localhost posts You should be able to see all of the data coming from the posts route but this time you will notice there are action buttons to create read update and delete the records BlitzTo demonstrate the CRUD functionality and how simple it is to implement one in the Blitz we will be building a to do application that will allow us to create read update and delete daily tasks Run the command blitz generate all todo name string That will create the necessary model query mutations and page routes We also passed in the string type for the to do task values Similarly to the refine scaffold Blitz took care of creating separate files for the create read update and delete operations for the to do tasks To test it out restart your developer server by pressing Ctrl C on your keyboard and then run blitz dev Then open your browser and navigate to localhost todos This will display the landing of the crud page asking you to create the first task since we currently do not have any data in our database Testing CRUD refineTo create a record click on the Create button in the top right corner This will open up a form with empty fields allowing you to enter the values and save a new record To read an already existing record click on the eye icon on the right of each record It will open up the record with all the values in read only mode In order to update an existing record click on the pencil icon next to the eye icon This will open up the form with all the values editable To delete the post click on the bin icon next to the eye icon It will also display a confirmation popup to make sure you are not deleting the record by mistake BlitzTo create a new task click on Create Todo It will open up an empty form where you can give the name of the task To read the created record navigate to the tasks list and click on the specific task This will open up the selected record in read only mode In order to edit the existing record open it and click on the Edit button That will allow you to change the title of the created to do task To delete the task open it and click on the Delete button Deployment refineFirst make sure you have a GitHub account If you do not have one make sure to create one for free Next sign in and create a new repository Now switch back to your code editor and run the following commands to push the code to the newly created repository git remote add origin git branch M maingit push u origin mainAfter the code is pushed switch back to the GitHub repository and you should see all the code being pushed To make sure your app is deployed in production and accessible online you will also have to deploy it to some hosting provider like Vercel First create a new free account if you already do not have one and log in Then create a new project by selecting the option Import from Git Find your GitHub project in the list and click Import Vercel will automatically configure everything for you all you have to do is manually add the environmental keys and values from the env file Once that s done click on Deploy and after the deployment process is done you will be given a live access link to your project The last thing for you to do is to switch back to Auth and change the allowed URLs to the deployment URL given by the Vercel previously those values were set to localhost BlitzWe will use Render which will allow us to deploy the app and the database First change the database provider to PostgreSQL To do that open schema prisma file and change the data source as shown below datasource db provider postgres url env DATABASE URL Then delete the db migrations folder so there is no previous migration history and no lock file for the database type Then create a new file render yaml in your project root and include the following configuration settings services type web name crud blitz env node plan free buildCommand npm i prod false amp amp blitz prisma generate amp amp blitz build amp amp blitz prisma migrate deploy startCommand blitz start p PORT envVars key NODE ENV value production key DATABASE URL fromDatabase name crud blitz db property connectionString key SESSION SECRET KEY generateValue truedatabases name crud blitz db plan freeNow push the code to GitHub Create a free account if you already do not have one and log in Next create a new repository Switch back to your code editor and run the following commands in your terminal git remote add origin git branch M maingit push u origin mainThen switch back to GitHub and you will find everything synced up Next create a free account on Render and log in Click on New and select the Blueprint option Next connect your Github account and find your project in the list Next give the Blueprint a name and click on Apply so Render sets everything up using your yaml configuration The setup might take a few minutes It will give you the live access link to your project once it s done ConclusionIn this article we compared two React frameworks refine and Blitz Both have TypeScript support by default are easy to set up come with CLI commands and do not require to use specific UI frameworks refine has a built in data provider This is great for testing and experimenting Blitz in comparison comes with SQLite and Prisma studio that offers UI to work with data For data tables refine comes with Inferencer which has already structured the data in the easy to perceive UI For Blitz you will have to build tables action buttons and other components yourself Blitz apps are already set with signup login and forgot password views with the models already create to store users and sessions in the database For refine you will have to create those from the ground up From the project tree standpoint Blitz looks more like a framework For those looking for a high flexibility on how to structure the project you will have to deal with the fact that most of the flow already follows a certain pattern refine is virtually a collection of hooks components and providers therefore users can fully design the app based on their individual needs and follow specific logic patterns based on their business schema	2023-03-16 12:18:55
