What is vite?
Vite is a modern frontend build tool that provides a faster and leaner development experience for modern web projects. It leverages native ES modules and is designed to serve your code via HTTP in development, enabling hot module replacement (HMR) for a fast development cycle, and bundles it for production using Rollup.
What are vite's main functionalities?
Instant Server Start
With Vite, you can start a development server instantly due to its use of native ES modules. Here's a simple command to start the server:
npx vite
Hot Module Replacement (HMR)
Vite provides out-of-the-box support for HMR, which enables you to update code and see changes in real-time without a full page reload. The code sample shows how to use HMR with a Vue application.
import { createApp } from 'vue';
const app = createApp(App);
if (import.meta.hot) {
import.meta.hot.accept();
}
Optimized Build
For production, Vite uses Rollup to bundle your code. This results in an optimized build that's ready for deployment. The command to create a production build is straightforward.
npx vite build
Plugin System
Vite supports a rich plugin system that allows you to extend its functionality. This code sample demonstrates how to include the official Vue plugin in your Vite configuration.
import { defineConfig } from 'vite';
import vue from '@vitejs/plugin-vue';
export default defineConfig({
plugins: [vue()]
});
TypeScript Support
Vite comes with built-in TypeScript support, allowing you to develop your application using TypeScript without additional setup. The command to start a server with TypeScript support is the same as for JavaScript.
npx vite --host
Other packages similar to vite
webpack
Webpack is a powerful module bundler that can transform and bundle various types of assets. It is highly configurable and has a large ecosystem of loaders and plugins. Compared to Vite, webpack has a steeper learning curve and can be slower in development due to its build process.
parcel
Parcel is a zero-configuration web application bundler. It offers a fast development experience and supports a wide range of file types out of the box. Parcel is similar to Vite in terms of ease of use, but Vite's development server is generally faster due to its use of native ES modules.
rollup
Rollup is a module bundler for JavaScript that compiles small pieces of code into something larger and more complex, such as a library or application. It is the same bundler that Vite uses for production builds. Rollup focuses on bundling for production and is not optimized for development speed like Vite.
snowpack
Snowpack is a build tool that uses JavaScript's native module system (ESM) for unbundled development. It provides a fast development experience by only rebuilding individual files as they change. Snowpack and Vite share similar philosophies, but Vite offers a more integrated experience with features like HMR and pre-configured plugins.
