海外TECH	DEV Community	How to Create a Single Page Application with React and Sanity	https://dev.to/sanity-io/how-to-create-a-single-page-application-with-react-and-sanity-2ggl	How to Create a Single Page Application with React and Sanity IntroductionHave you ever thought of building a single page application SPA with react amp Sanity In this guide I will take you on an exciting journey to build your first SPA with react and Sanity We will create a Food Catalog app that will contain various food items and categories to organize them by themselves All these categories and foods will be fetched from Sanity Here is the project GitHub repository you can clone or download the complete project You can also see the deployed app here Note This is a follow along kind of article You ll definitely have a good result if you build along Requirements PrerequisitesTo understand this guide and code along you should have Basic understanding of HTML CSS and JavaScriptAt least a little experience or knowledge of React and some of its hooks Node and npm or yarn installed on your computerBasic understanding of how the terminal works What is React React is an open source JavaScript library created for building fast and interactive user interfaces for web and mobile applications It is maintained by Facebook and a community of individual developers and companies React can be used for the development of single page or mobile applications React is a component based framework which means we ll be writing our code in small reusable pieces and putting them all together to make our website Understanding SPASPA stands for Single Page Application It is a web application or website that interacts with the user by dynamically rewriting the current page rather than loading entire new pages from the server In simpler terms it is an app that works inside a browser and does not require page reloading during use We ll also touch on how routing works in React and learn how to map different parts of our website to different views Setting up a React appFor this guide we will make use of create react app ーthe React recommended way to create a single page application To make use of create react app You ll need to have Node gt and npm gt on your machine To install run the following command npx create react app food catalog appAfter the installation you can move into the project s root directory to start the development server cd food catalog appnpm startWhen the dev server is ready you can view your project in the browser at http localhost Your project directory should look like this once the setup is complete Let s clean up the app by deleting files we don t need so we can get started building our app You can delete the following highlighted files Note This might throw an error so ensure you delete the logo svg import from App css and the index css reportWebVitals js import from index js To be sure your files look like mine exactly I pushed my setup files to this GitHub repository and you can clone it or cross check Using Tailwind CSSTailwindCSS is a utility first CSS framework used to build frontend applications Rather than adding obscure CSS classes to your code with TailwindCSS you use utility classes to create your components with as much control over every single styling as you want All without having to ever write a single line of CSS There are so many ways to make use of Tailwind CSS in React and other frameworks generally but for this guide we will be making use of the CDN In the src folder add the following CDN import to the App css file import url dist tailwind min css Once this is done we can now proceed to set up our sanity studio What is Sanity Sanity is a content platform that treats your structured content as data It comes bundled with an open source real time headless CMS that can be customized with JavaScript We ll be using the Sanity studio to manage our content and accessing it in our frontend through Sanity s out of the box API One of the key benefits of Sanity is that the content management interface or studio is open source and built to be built upon If you know React you can extend and customize it to your heart s content Getting started with Sanity setupTo start a new project with Sanity we ll install the Sanity CLI globally To do this you will need to have Node and npm installed npm install g sanity cliAs soon as the CLI finishes installing you ll be able to create a new project using it Run the following in the directory of the React project you just created i e food catalog app sanity initIf this is your first time this will log you into Sanity and then you will be able to create a project set up a dataset and generate files that are necessary to run the editing environment locally Note If you don t have an account Sanity will direct you on how to get one Or you could visit Sanity s website and create an account Once that is done you will be prompted to create a new project tap Enter Name your project food catalog studio and choose the default dataset configuration by typing Y Finally confirm the project path and choose a schema for your studio For this demo you ll need to start with the Clean project with no predefined schemas option To start the studio move to the folder by running the following command in the terminal cd studioNow you can start the studio with the following command sanity startAfter compiling the studio will open on http localhost and we will have something like this displayed because we choose clean project with no predefined schemas when setting up our studio Sanity studioThe Sanity Studio is an open source CMS built with React js that allows users to use toolkits and plugins to create the workflow that optimizes for how you want to work with content It offers rapid configuration and free form customization Creating a food catalog schema from scratchA schema describes the different field types in a document There are different types of schema you can choose from For this guide we will be creating two schemas one for the food categories and the other for food items The food schema will have properties such as food name food description food image and its category while the category schema will have the name image description and then a hex code field for creating dynamic styling When the studio starts up it looks for the schema js file in the schemas folder of your project For now since we don t have any schema you will find something like this in your schema js file First we must import the schema creatorimport createSchema from part sanity base schema creator Then import schema types from any plugins that might expose themimport schemaTypes from all part sanity base schema type Then we give our schema to the builder and provide the result to Sanityexport default createSchema We name our schema name default Then proceed to concatenate our document type to the ones provided by any plugins that are installed types schemaTypes concat Your types here All your schemas go into the types array by defining the schemas title name type and finally the fields For our foods schema we will be having something like this types schemaTypes concat Your types here title Foods name foods type document fields title Food Name name foodName type string validation Rule gt Rule required title A little description name foodDesc type text options maxLength validation Rule gt Rule required title Food Image name foodImage type image options hotspot true Category schema goes here Once you have done this save and now let s take a deeper look at the code above each object represents a field and must have a title name and type Title The display name for this fieldName The identifier for this field used in the API sType The type of this field e g string image e t c You can find the complete list of built in types here The second schema to create is the category schema which we ll add just below the foods schema object name category title Category type document fields title Title name title type string title Slug name slug type slug options source title maxLength title Description name description type text title Image name image type image options hotspot true title Hex Code name hexCode type string Save the file and you will see something like this One last thing to do will be to include a category in our foods schema It displays the category fetched from the category schema for you when filling in your foods To do that we will create a new field wherever in the array we want this field to be name category title Category type reference to type category Once you save your code and create a new document of type food in your studio you should see the categories field show up as expected Organizing our schemaLet s organize our schemas before loading them with foods and categories Having all our schemas in just one file will always work but can become very difficult to maintain when you have more schemas It is recommended to describe each document type in a separate file and import them into schema js like this First we must import the schema creatorimport createSchema from part sanity base schema creator Then import schema types from any plugins that might expose themimport schemaTypes from all part sanity base schema type import foods from foods import category from category Then we give our schema to the builder and provide the result to Sanityexport default createSchema We name our schema name default Then proceed to concatenate our document type to the ones provided by any plugins that are installed types schemaTypes concat foods category Looking deeper at the code above we imported two files that export the schemas and called them in the types array At this point your directory will look like this One last thing will be for us to load our studio with content which we will be fetching into the app This is totally up to you you can get lovely images from Unsplash Connecting Sanity with React AppLet s allow our frontend to query for and receive data from Sanity Connecting React to SanityThis is done by installing the sanity client package in our React project Then run this command npm install sanity client sanity image url sanity client ーSanity Client is the official JavaScript client by Sanity and can be used both in Node js and modern browsers sanity image url ーA helper library used to generate image URLs and perform helpful image transformations through the Sanity asset pipeline Read more on the official docs here Once these packages have been installed we ll create a new file named client js inside the src directory and add the following code to the client js file import sanityClient from sanity client export default sanityClient projectId Your Project ID Here find this at manage sanity io or in your sanity json dataset production this is from those question during sanity init Note To get your project ID visit click on the project so it displays full info about the project including the Project ID Ensure you save the file Connecting Sanity to ReactFinally You will also need to add the port where the React development server is running to the CORS origins of your Sanity project Visit and click on your Sanity project On your project s dashboard click on Settings →API settings and then add http localhost to the CORS origins field if it was not added automatically Once you save that will be all for our sanity studio we can now start building the front end of our app to consume the data from the sanity studio Building a food catalog applicationThe first thing to handle would be routing and this is usually handled in the App js file We ll be implementing this using react router dom and the Switch and Route components We will create a new folder in the src directory to put all our routes in this app We will have four routes views Home js The main index is where we will list all the categories fetched from the Sanity studio views Foods js This will contain a random list of all foods fetched from the Sanity studio views About js This is the about page of the application views FilteredFoods js This is an individual page containing foods related to a particular category Let s create the above files and our file directory will now look like this Let s now handle routing in the App js file In this file we will handle routing using React router This enables the navigation among views of various components in a React Application The first thing will be to install the React Router package using the command below npm install react router dom saveAfter installing react router dom add its components BrowserRouter Route Switch to the App js file You can now proceed to define your routes In the code below you will notice all the routes are wrapped in the Switch and BrowserRouter components The Switch component is used to render only the first route that matches the location rather than rendering all matching routes and the BrowserRouter is a router implementation that uses the HTML history API to keep your UI in sync with the URL It is the parent component that is used to store all the other components Learn more about routing in react here import BrowserRouter Route Switch from react router dom viewsimport Home from views Home import About

You can confirm if the routes are working visiting the paths Now the next thing would be to work on the NavBar of our application Let s now create a folder and name its components in the src directory to house all our reusable components This would help organize our application In this folder we have about five different components but let s start with the Header section of our application Building the Header and footer SectionThe header section is going to house the application s logo and nav links while the footer section will contain footer text We mentioned earlier that React is all about components so let s make some components Header js This would be the overall container housing the Navbar import React from react import NavBar from NavBar const Header gt return lt header gt lt div className bg gray gt lt NavBar gt lt div gt lt header gt export default Header In the above code we created a functional component and then imported Navbar js components NavBar js This will contain

we declared in App js to work we need to import NavLink from react router dom and then made use of NavLink in the navbar components Footer js This will contain the footer text which is very simple import React from react const Footer gt return lt div className bg gray flex justify center font bold p gt lt p gt Sanity Tutorial Guide by lt a href style color FEC gt amp nbsp Joel Olawanle lt a gt lt p gt lt div gt export default Footer The last thing will be to add Header js and Footer js files to our App js file making the app js file to now look like thisimport BrowserRouter Route Switch

but no content Let s now work on the index page so it displays all our categories from Sanity Display all food categories on the Homepageimport React from react import Categories from components

lt div gt lt hr className my gt lt Categories gt lt section gt export default Home In the code above we have a div containing welcome information and a search bar and then after that we imported a component called categories from the components folder To continue you will have to create a component and name it Categories js in the components folder This is where we will fetch all our food categories from Sanity either using GROQ or GraphQL For this guide we will make use of GROQ Please paste the following code in the Categories js file import React useState useEffect from react import sanityClient from Client import Category from Category const Categories gt const categories setCategories useState null useEffect gt sanityClient fetch type category title slug description image asset gt id url hexCode then data gt setCategories data catch console error return lt div className gt lt h className text xl font bold text center my lg my gt All Categories lt h gt lt div className flex flex col lg flex row lg justify center flex wrap w full gap my gt categories amp amp categories map category gt lt Category key category id category category gt lt div gt lt div gt export default Categories The above code might seem tricky since we are now fetching data from our Sanity but I will explain Let s first understand what GROQ is all about GROQ Graph Relational Object Queries is a declarative language designed to query collections of largely schema less JSON documents Note If you re not yet familiar with GROQ which is used to query Sanity for data check the official docs here Explaining the code The first thing we did was to import Sanity Client which we installed earlier import sanityClient from Client In react we make use of some hooks to query for data For this guide we will make use of useState and useEffect The useState is a Hook that allows you to have state variables in functional components while useEffect lets you perform side effects in function components To make use of these two hooks you have to import them from react and that s what we did in the first line alongside react which is necessary import React useState useEffect from react We can now set our statesconst categories setCategories useState null Note This follows a common pattern where categories is where we access the current value of that particular piece of state while setCategories is our method for setting or changing it To fetch data information from Sanity studio you can make use of GROQ let s now explore our Groq Query useEffect gt sanityClient fetch type category title slug description image asset gt id url hexCode then data gt setCategories data catch console error This query is searching through your Sanity data store or Content Lake for a schema that has a type of category this is the name of the schema and then gets the title slug description e t c Reading further through our code you ll notice that we are looping through our categories array and mapping each item to an instance of our Category component categories amp amp categories map category gt lt Category key category id category category gt In the category js file paste the code below and saveimport React from react import Link from react router dom import sanityClient from Client import imageUrlBuilder from sanity image url const builder imageUrlBuilder sanityClient function urlFor source return

backgroundColor FEC className rounded mt px py text white gt View lt button gt lt Link gt lt div gt export default Category In the above code we imported imageUrlBuilder from sanity image url which we use to generate image URLs for our images by creating a method called UrlFor and making use of it inside the template This helps us get thumbnail sized images compared to the regular size of images uploaded to Sanity Note A lot of things can be done with imageUrlBuilder such as specifying width and height You can read more about imageUrlBuilder here Once you save you will notice the homepage index page now looks like this depending on the data you entered into your studio Display all foods on Food s pageJust as we were able to display all categories on the home page we will also use the same approach to display all foods on the foods page In the views Foods js paste the code below import React useState useEffect from react import Link from react router dom import sanityClient from Client import imageUrlBuilder from sanity image url const builder imageUrlBuilder sanityClient function urlFor source return builder image source import foodImage from images protein jpg const Foods

lt section gt export default Foods In the code above We are simply fetching all the foods from the foods schema of our sanity studio Once you save you will get something like this depending on what you have in your sanity studio Finally let s take a look at something very important you will notice some links in the foods page and home page which are supposed to take us to a dynamic route Let s now see how it works Create dynamic routes for each categoryTo create a dynamic route we will be making use of a component We will be making use of the FilteredFoods js page and if you recall when we were declaring routes we added a slug to the route of this page lt Route component FilteredFoods path FilteredFoods slug gt We will get that slug via useParams which we would import into this component In the FilteredFoods js component paste the code below import React useState useEffect from react import useParams Link from react router dom import sanityClient from Client import imageUrlBuilder from sanity image url const builder imageUrlBuilder sanityClient function urlFor source return builder image source const Foods gt const filteredFoods setFilteredFoods useState null const slug useParams useEffect gt sanityClient fetch type foods amp amp category ref in type category amp amp title slug id id foodName foodDesc foodImage asset gt id url category gt title then data

thing we did was to import useParams which would enable us to get the slugconst slug useParams Once that is successful we can now query our sanity studio but this time around the query is quite different To get a feeling for queries in GROQ you can check their cheat sheet here Once you save this code you will now be able to access dynamic routes via the Link declared either in the home page or foods page lt Link to filteredfoods category slug current gt lt button style backgroundColor FEC className rounded mt px py text white gt View lt button gt lt Link gt By now the whole application

海外TECH	DEV Community	Image Processing is Easier than you Thought! (Getting started with Python Pillow)	https://dev.to/saharshlaud/image-processing-is-easier-than-you-thought-getting-started-with-python-pillow-329k	Image Processing is Easier than you Thought Getting started with Python Pillow We live in a digital world today with data flowing all around us We come across lots of digital images which has made digital image processing very beneficial for us since it allows us to enhance an image and helps in the extraction of useful information from these images Python is a general purpose programming language that provides many image processing libraries for adding image processing capabilities to digital images Some of the most common image processing libraries in Python are OpenCV Python Imaging Library PIL Scikit image etc The Python Imaging Library PIL is also known as Pillow in the newer versions although Pillow has forked the PIL repository and added Python x Support The following steps are generally followed while processing an image Importing the image via image acquisition tools Analyzing and manipulating the image Output can be an altered image or a report based on that image PIL is the best option for performing simple image processing such as resizing scaling rotation trimming partial cutout and applying various filters to an image since it is simpler and easier to understand than other libraries such as OpenCV It comes with support for a wide variety of image formats such as “jpeg “png “gif “ppm “tiff etc which makes image processing relatively easier Today we shall take a deep dive into Python PIL and its features along with the code implementation Installation Windows We can install pillow using pip on Windows systems Just run the below command in your command prompt window ​pip install pillow or easy install Pillow MacOS To install Pillow on MacOS run the following code on your Bash terminal sudo pip install Pillow Linux To install Pillow on Linux machines simply use sudo pip install Pillow Loading an image For loading an image firstly we need to import the Image from PIL and then call the Image open function passing the image path A value of the Image object data type is returned by the Image open function and this image object can be used to perform various image manipulations with the help of other methods All the modifications made to the image object can be saved to an image file with the save method The show method displays the image that has been loaded in the image object importing the modulefrom PIL import Image opening the image stored in the local path im Image open D Image Kingfisher jpg im show Output Basic Image Properties We can find the basic properties of the image such as size width height format and mode using different functions in the Image module importing the modulefrom PIL import Image im Image open D Image Kingfisher jpg Find image dimensions i e width and heightprint Image size im size Find the image formatprint Image format im format Find the image mode i e RGB RGBA HSV etc print Image mode im mode Output Image size Image format JPEGImage mode RGB Converting image into other formats ​​We can easily convert one image into other format using the save method in Image module This method takes two arguments first the name of the new file and second the format into which we want to convert the image importing the modulefrom PIL import Image im Image open D Image Kingfisher jpg Changing image format and saving the new imageim save Kingfisher png png Output The following is the image with changed format Cropping images The Image crop method helps in cropping the image and we can specify the dimensions of the crop The crop method takes a valued tuple defining the left upper right and lower pixel coordinates importing the modulefrom PIL import Image im Image open D Image Kingfisher jpg Cropping the loaded image using crop img crop im crop img crop show Output Rotating images The Image rotate function can be used to rotate an image It takes the rotation degree value as a parameter and returns a rotated copy of the image from PIL import Imageim Image open D Image Kingfisher jpg Rotating image using rotate function by degrees img rotate im rotate img rotate save Kingfisher Rotated jpg Output Resizing images The Image resize function can be used to resize an image to required height and width The function takes width and height as a tuple and returns an image object of resized format from PIL import Imageim Image open D Image Kingfisher jpg Resizing an image using resize function img resize im resize img resize show Output Blur an image The ImageFilter module consists of definitions for a pre defined set of filters These filters can be used with the filter method and we can even blur an image by applying ImageFilter BLUR on the original image The filter function then returns an image object that contains the blurred copy of the original image importing Image and ImageFilter modulesfrom PIL import Image ImageFilter im Image open D Image Kingfisher jpg Applying blur operation on the imageimg blur im filter ImageFilter BLUR img blur show Output Grayscale Image The Image convert method allows us to convert colored images into grayscale images black and white importing Image and ImageFilter modulesfrom PIL import Image ImageFilter im Image open D Image Kingfisher jpg grayscale im convert L grayscale show Output Image enhancement filters The ImageFilter module contains various filters that can be used for image enhancement such as CONTOUR DETAIL EDGE ENHANCE EMBOSS SMOOTH SHARPEN etc Some of these filters are displayed below importing modulesfrom PIL import Image ImageFilterim Image open D Image Kingfisher jpg Applying filtersimg im filter ImageFilter CONTOUR img im filter ImageFilter EMBOSS img show img show Output Contour filter Emboss filter Drawing on image Using the ImageDraw module we can easily draw simple D graphics on top of existing Image objects After importing the ImageDraw module we simply create an ImageDraw Draw object passing the Image object as the parameter Then we can we can draw various objects such as line rectangle circle triangle etc using the inbuilt functions Here we have drawn a rectangle on the existing image The rectangle function takes three parameters the position of the four corner points the outline color and the fill color values importing required modulesfrom PIL import Image ImageDrawim Image open D Image Kingfisher jpg draw ImageDraw Draw im Drawing a rectangle using rectangle method draw rectangle fill red outline blue im show Output Getting RGB values The ImageColor module consists of functions relating to RGB manipulation ImageColor getrgb method converts a color value passed as a string into the equivalent RGB format It takes the color string as an input and returns a tuple of RGB values importing ImageColor modulefrom PIL import ImageColorim ImageColor getrgb ff print im im ImageColor getrgb yellow print im Output We can even create a new image consisting of given RGB color value using the new and getrgb method importing required modulesfrom PIL import Image ImageColorimg Image new RGB ImageColor getrgb FF img show Output Last words This was all about the Python Imaging Library and its basic functionalities The PIL library makes it relatively easy to adjust and process images according to our requirements with just a few lines of code Now what are you waiting for Go ahead and get started with your image processing journey Hope you enjoyed my blog Thanks for reading Feel
