Vite vs Create-React-App: A Comprehensive Comparison and Migration Guide for 2023

Introduction

When starting a new React project, developers often turn to popular tools like Create-React-App or Webpack to set up their environment. However, in recent years, Vite has emerged as a faster and more efficient alternative to these tools.

This article will provide a comprehensive comparison between Vite and Create-React-App and serve as a migration guide for those looking to switch to Vite.

Key Takeaways:

  • Vite is a faster and more performant alternative to Create-React-App.
  • Vite offers additional features such as Vite plugins, absolute imports, and environment variables.
  • Migrating from Create-React-App to Vite requires some prerequisites but can be done using a step-by-step guide.
  • There are alternative React project templates such as React-boilerplate, React-starter-kit, Create-next-app, Gatsby, and T3 stack.
  • Vite is compatible with React and offers improved developer experience compared to Webpack.

What is Vite?

Vite is a build tool that was specifically designed to optimize the development experience for modern web applications. Vite leverages native ES modules and compiles code on the fly, resulting in faster start-up times and an overall more performant development experience. Vite also offers additional features such as Vite plugins, absolute imports, and environment variables.

Create-React-App

While Create-React-App is a popular choice for setting up a React project, there are some disadvantages to using it. One of the most significant disadvantages is its slower performance compared to Vite. There are also alternative React project templates available for those looking for more flexibility and customization options.

Why choose Vite over Create-React-App?

There are several advantages to using Vite over Create-React-App, including:

Performance improvements:

Vite offers faster server start-up, faster file update reflection, improved build performance, async chunk loading optimization, and CSS code splitting. These features can lead to a more efficient and faster development experience.

Features:

Vite offers a range of features, including Vite plugins and compatibility, absolute imports, and environment variables. These features can make it easier to build and maintain React applications.

Differences between Vite and Create-React-App:

There are several key differences between Vite and Create-React-App. One of the main differences is that Vite leverages native ES modules, whereas Create-React-App uses a more traditional CommonJS system. Additionally, Vite compiles code on the fly, resulting in a faster development experience. Vite also offers additional features such as Vite plugins, absolute imports, and environment variables.

Using Vite with React

Vite is compatible with React, and creating a Vite React app is a straightforward process. When deciding whether to use Vite instead of Create-React-App, it's essential to consider the performance benefits and additional features that Vite offers. Vite can also be integrated into an existing React project with some configuration changes.

Setting Up a React Project with Vite 3.0

To set up a React project with Vite, follow the steps below:

  1. Open a terminal and navigate to the directory where you want to create your project.

  2. Run the following command to create a new React project using Vite:

npm init vite@latest vite-project --template react

This command will create a new React project with Vite as the build tool.

  1. Once the project is created, navigate to the project directory:
cd my-react-project
  1. Start the development server by running the following command:
npm install
npm run dev

This will start the development server, and your React app will be accessible at http://localhost:3000.

Migration Steps from Create-React-App

Migrating from Create-React-App to Vite requires some prerequisites, such as having Node.js and Yarn or npm installed. Once these prerequisites are met, setting up a React project with Vite 3.0 is straightforward.

Prerequisites for Migrating from Create-React-App to Vite:

Before you begin migrating your Create-React-App project to Vite, there are a few prerequisites that you need to fulfill:

  • Node.js and npm should be installed on your machine.
  • Your Create-React-App project should be up-to-date.
  • You should have some knowledge of using a command line interface.

Step-by-Step Guide for Migrating a Create-React-App Project to Vite

To migrate your Create-React-App project to Vite, follow the steps below:

  1. Open the package.json file in your project folder and remove react-scripts from the list of dependencies:
"dependencies": {
  ...
  "react-scripts": "5.0.1",
  ...
},
  1. Add "devDependencies" with the following code:
"devDependencies": {
  "@vitejs/plugin-react": "^2.0.1",
  "vite": "^3.0.7"
},
  1. Replace the existing scripts with the following code:
"scripts": {
  "start": "vite",
  "build": "vite build"
},
  1. In the public/index.html file, remove every %PUBLIC_URL%/ prefix in the link paths, and replace them with the following:
<link rel="icon" href="./public/favicon.ico" />
 ...
<link rel="apple-touch-icon" href="./public/logo192.png" />
 ...
<link rel="manifest" href="./public/manifest.json" />
  1. Add an entry point script inside the body element, just below the root div:
<script type="module" src="/src/index.jsx"></script>
  1. Before adding the entry point script, rename every .js file that contains React code to a .jsx file.

  2. Move the public/index.html file to the root folder.

  3. Create a Vite config file by creating a vite.config.js file inside the root folder and adding the following code:

import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";

export default defineConfig({
  plugins: [react()],
});
  1. Delete the node_modules folder, and then run the following command to reinstall the dependencies and start the development server:
npm install
npm start

This will start the development server, and your Create-React-App project will now be running on Vite.

Note: It's possible that some of your dependencies may not work with Vite. In that case, you'll need to find alternatives or make changes to your code accordingly.

Alternatives to Create-React-App and Vite

In addition to Create-React-App and Vite, there are alternative React project templates such as -

  • React-boilerplate
  • React-starter-kit
  • Create-next-app
  • Gatsby
  • T3 stack

Each of these templates offers unique features and benefits and may be a better fit for certain projects.

Vite and Webpack

Vite is often compared to Webpack, another popular bundling tool for React applications. While there are similarities between the two, there are also some key differences.

Vite offers faster build times and server start-up, as well as easier configuration and a more streamlined development experience. While Vite can be used as a replacement for Webpack, it's important to note that they have different use cases and there may be instances where Webpack is still the better option.

Conclusion

In conclusion, both Vite and Create-React-App have their own advantages and disadvantages. While Create-React-App is a great tool for quickly setting up a React project, Vite offers significant performance improvements and customization options. It's important for developers to consider their specific needs when deciding which tool to use for their projects.

Using Vite with React can greatly enhance the development experience, and the compatibility between the two tools makes it easy to integrate Vite into an existing React project. While there may be a learning curve for developers who are used to Create-React-App or Webpack, Vite's benefits make it a worthwhile investment.
