![]() ![]() The other code snippet which is important is Since the state changes here, the component and its child component will be rerendered. The above code snippet tells that whenever the button is clicked, then change the state of selectedCustomer to the selected customers' id. import React, >Įvery customer in the list has a button called as Click to View Details. Inside src folder create a file called as FirstComponent.js and copy the following code into FirstComponent.js. Each component can have multiple child components and the components can communicate with each other. An Application is nothing but a collection of components. In order to see the build folder Run the following commandĪ Component in React does a specific functionality. These converted files are stored in the build folder after bundling and minification. So JSX needs to be converted into javascript before deploying. React Apps can be developed using either JSX, or normal JavaScript itself, but using JSX definitely makes things easier to code for the developer :). build: This is the folder where the built files are stored.src/App.css : This is the CSS file corresponding to App Component.App Component is the main component in React which acts as a container for all other components. src/App.js : This is the file for App Component.src/index.css: The CSS file corresponding to index.js.This is nothing but the div element present in index.html. The above line of code is telling that App Component ( will cover App Component soon) has to be loaded into an html element with id root.ReactDOM.render(, document.getElementById(‘root’)) This file has the following line of code which is very significant. src/index.js: This is the javascript file corresponding to index.html.This line is very significant since all the application components are loade d into this div. This will be the only html file in the entire application since React is generally Written using JSX which I will cover later. public/index.html: When the application starts this is the first page that is loaded.package.json: This File has the list of node dependencies which are needed.Here I will list out some of the important files and folders that you should be aware of. When you created the project, you would have noticed that it created a bunch of files. The Application will look like this in your browser: Basic Folder Structure Explained You should be able to see that your application is running. Go to your browser and go the following URL localhost:3000 In order to test if everything has been set up properly, go into the project folder and start the application using the following command. The above command creates a folder called first-react-app which is the project folder. npx create-react-app first-react-appįirst-react-app is the name of the application. Use the following command to create the project. The project can be created using create-react-app. npm install -g create-react-app Create The Project Install create-react-app node package globally using the following command. Install create-react-app Node PackageĬreate-react-app node package helps to set up a React project. NodeJS is needed since the Libraries Required for React are downloaded using node package manager ( npm ). Part 1 Install NodeJS if not already present This code demonstrates the use of components, communication between components, making HTTP calls and React Bootstrap (bootstrap which is written for React). The Second Part explains an existing code that I have posted in Github.The First Part demonstrates how to create a simple React app using ‘create-react-app’ CLI and explains the project structure.Someone stated AppJS is built on top of that. Let me know if you find something interesting :)ĬEF - Chromium Embedded Framework could be also interesting option. ![]()
