![]() This way, the number of HTTP requests made within the app is significantly reduced, which directly improves the app’s performance on the network. Think of webpack as a tool that bundles up all your source files and creates a single bundle.js file that can be served from the index.html file inside a tag. In order to understand this, we need to learn about one more concept in the world of modern JavaScript toolchains, which is webpack. The bundled scripts are finally placed into the title of this HTML file. tags usually aren’t displayed on the webpage but are machine parsable. ![]() The tags provide metadata about the HTML document. To create a production bundle, use `npm run build` or `yarn build`. To begin the development, run `npm start` or `yarn start`. You need to enable JavaScript to run this app. Let’s take a look at this file’s contents: This index.html serves as a template for generating build/index.html, which is ultimately the main file served on the browser. Let’s look at the files inside the public folder. This folder contains the index.html and manifest.json files. Basically, the packages you want to use by calling an import statement go here. node_modules of the current package root. Now, cd into the rate-restaurants directory. This command runs for a few seconds and exits happily after creating a bare-bones React application under a new directory called rate-restaurants. Let’s call our application rate-restaurants: ~ npx create-react-app rate-restaurants Run the following npx command on a terminal to install and bootstrap the application using Create React App. In this tutorial, we will build a simple SPA that displays restaurants on a webpage and lets users rate them. Now that we have relevant context about Create React App let’s start by installing it. It is actively maintained and regularly updated with new features and bug fixes.It includes a comprehensive set of development tools, such as linting and testing, out-of-the-box.It comes with a built-in development server that allows you to see changes in real time as you make them.It abstracts away the complex configurations that come with creating a new React project.Some other reasons why you should use this tool are as follows: Why should you use Create React App?Ĭreate React App is a great tool for quickly getting up and running on new React projects. If you’re interested in contributing, the repository’s contributing page is an excellent place to start. The GitHub repository is very active and maintained by the creators, along with many open source developers from different parts of the world. It sets up your development environment so that you can use the latest JavaScript features, provides a nice developer experience, and optimizes your app for production.Ĭreate React App was created by Joe Haddad and Dan Abramov. It is specifically recommended by the React community for building single-page applications (SPAs) and for learning React (for building “Hello, World!” applications). What is Create React App?Ĭreate React App is also a toolchain. For instance, Next.js is great for building a server-rendered website, and Gatsby is optimized for static, content-oriented websites like blogs and newsletters. In React development, different toolchains satisfy different requirements for product development. In this case, the compiler and CMake become part of the toolchain. ![]() For instance, in C++ development, we need a compiler to compile the code and a build system like CMake to manage all the dependencies if the project is fairly big. In other words, any software development framework is made up of a bunch of supporting tools optimized to do specific functions. In simple terms, a toolchain is a set of distinct software development tools linked by specific stages.
