Introduction to Vite: Next-Generation Frontend Tooling

. main.jsx mounts the root component into the DOM. File-based Config and Setup Uses a file-based configuration to manage build behavior, development server options, and plugin setup. This configuration is defined in vite.config.js or vite.config.ts for customizing how Vite handles your project’s framework integration and static assets. This centralized config file ensures consistent behavior across development and production environments. import { defineConfig } from 'vite'; import react from '@vitejs/plugin-react'; export default defineConfig({ plugins: [react()], }); Explanation: defineConfig provides typing and structure for Vite config @vitejs/plugin-react official plugin for JSX, HMR, and Fast Refresh in React apps. react() initializes the plugin. plugins: [react()] registers the React plugin with Vite’s plugin system. export default: makes the configuration available to Vite CLI and server. Using Plugins for Video Files To copy video files into the production bundle or process them at build time, plugins like vite-plugin-static-copy can be used. import { defineConfig } from 'vite'; import react from '@vitejs/plugin-react'; import viteStaticCopy from 'vite-plugin-static-copy'; export default defineConfig({ plugins: [ react(), viteStaticCopy({ targets: [{ src: 'videos/*', dest: 'assets/videos' }], }), ], }); Explanation: vite-plugin-static-copy: plugin that copies static files during build. targets: defines source and destination for copy. src: 'videos/*': includes all files inside the videos/ folder. dest: 'assets/videos': places copied files inside dist/assets/videos . Importing Static Video Assets Static video files ( .mp4, .webm, .vtt, etc.) can be placed in public/ for direct URL access, or imported using the module system. import videoSrc from './assets/tutorial.mp4'; Explanation: Imports the video as a module. Vite processes the file and generates a hashed URL. Used when referencing the video via a dynamic JS variable (e.g., src={videoSrc} in JSX). <video controls width='100%'> <source src='/videos/tutorial.mp4' type='video/mp4' /> </video> Explanation: Directly references a statically served video file. src points to a file inside public/videos or dist/videos (after using copy plugin). Used when video is not imported in JavaScript. Configuring Video Streaming with Environment Variables For dynamic video URLs (e.g., Cloudflare Stream, api.video), environment variables can store base URLs or playback tokens. VITE_STREAM_BASE_URL=https://video.example.com Explanation: Declares an environment variable to store the base URL for a video API or CDN. Must be prefixed with VITE_ to be exposed to the frontend. const baseURL = import.meta.env.VITE_STREAM_BASE_URL; Explanation: import.meta.env: Vite’s way to access environment variables at runtime. VITE_STREAM_BASE_URL is read from .env and used in the app logic (e.g., to build video RLs). TypeScript Integration for Video Components Allows you to enforce typing for video-related components, ensuring predictable behavior and reducing runtime errors. Defining interfaces or types for props like ` src `, ` poster `, and ` captions ` maintains clear contracts between components and improves code maintainability when working with dynamic video content. Use TypeScript to define strict types for video props: type VideoProps = { src: string; poster?: string; captions?: string; }; const VideoPlayer = ({ src, poster }: VideoProps) => ( <video controls poster={poster}> <source src={src} type='video/mp4' /> </video> ); Explanation: VideoProps defines a type for expected props: src i s required, poster and captions are optional. VideoPlayer is a functional component typed with VideoProps. poster={poster} sets the preview image before playback. <source> injects the dynamic video URL and specifies the video format. Building and Previewing Production Output To create a production build, run: npm run build Vite outputs static files to the dist/ directory using Rollup. To preview the production output locally: npm run preview Serves the dist/ directory on a local server.
