Vite vs Webpack vs esbuild: Porównanie narzędzi budowania

The JavaScript build tool landscape has evolved dramatically. In 2025, developers must choose between Webpack, Vite, esbuild, and Turbopack — each with radically different architectures and trade-offs. This comprehensive guide compares all four across dev server speed, production build performance, configuration complexity, plugin ecosystems, and framework support to help you pick the right bundler for your project.

The Build Tool Landscape in 2025

Modern JavaScript applications need a build step. Browsers do not natively understand TypeScript, JSX, Vue SFCs, or CSS modules. A build tool transforms your source code into optimized bundles that browsers can execute. But the job goes far beyond transpilation: build tools also handle code splitting, tree shaking, hot module replacement (HMR), asset optimization, and dependency resolution.

For years, Webpack was the undisputed king. It pioneered concepts like code splitting, loaders, and plugin-based architecture. But its JavaScript-based architecture hit performance walls as projects grew larger. This opened the door for a new generation of tools written in faster languages: esbuild (Go), Vite (leveraging esbuild + Rollup), and Turbopack (Rust).

The core tension is between maturity and speed. Webpack has the richest ecosystem but slower builds. esbuild is blindingly fast but has a limited plugin API. Vite strikes a pragmatic balance by using esbuild for development and Rollup for production. Turbopack, backed by Vercel, aims to be the successor to Webpack with Rust-level performance.

Webpack: The Config-Driven Veteran

Webpack was created by Tobias Koppers in 2012 and has been the default bundler for most JavaScript projects for over a decade. It treats every file — JavaScript, CSS, images, fonts — as a module in a dependency graph. Loaders transform files, plugins extend functionality, and the output is one or more optimized bundles.

Configuration Example

// webpack.config.js
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');

module.exports = {
  entry: './src/index.tsx',
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: '[name].[contenthash].js',
    clean: true,
  },
  resolve: {
    extensions: ['.tsx', '.ts', '.js', '.jsx'],
    alias: {
      '@': path.resolve(__dirname, 'src'),
    },
  },
  module: {
    rules: [
      {
        test: /\.tsx?$/,
        use: 'ts-loader',
        exclude: /node_modules/,
      },
      {
        test: /\.css$/,
        use: [MiniCssExtractPlugin.loader, 'css-loader', 'postcss-loader'],
      },
      {
        test: /\.(png|svg|jpg|jpeg|gif)$/i,
        type: 'asset/resource',
      },
    ],
  },
  plugins: [
    new HtmlWebpackPlugin({
      template: './public/index.html',
    }),
    new MiniCssExtractPlugin({
      filename: '[name].[contenthash].css',
    }),
  ],
  optimization: {
    splitChunks: {
      chunks: 'all',
      cacheGroups: {
        vendor: {
          test: /[\\/]node_modules[\\/]/,
          name: 'vendors',
          chunks: 'all',
        },
      },
    },
  },
  devServer: {
    port: 3000,
    hot: true,
    historyApiFallback: true,
  },
};

Vite: Native ESM Dev Server + Rollup Production Builds

Vite (French for "fast") was created by Evan You (creator of Vue.js) in 2020. It fundamentally rethinks the dev server by leveraging the browser's native ES module support. Instead of bundling your entire application before serving it, Vite serves source files directly as ES modules and lets the browser handle imports. This results in near-instant server startup regardless of project size.

For production builds, Vite uses Rollup under the hood, which produces highly optimized bundles with excellent tree shaking. Starting from Vite 5, it also uses esbuild for dependency pre-bundling and TypeScript/JSX transpilation during development.

Key Features

Configuration Example

// vite.config.ts
import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';
import path from 'path';

export default defineConfig({
  plugins: [react()],
  resolve: {
    alias: {
      '@': path.resolve(__dirname, './src'),
    },
  },
  server: {
    port: 3000,
    open: true,
  },
  build: {
    rollupOptions: {
      output: {
        manualChunks: {
          vendor: ['react', 'react-dom'],
          router: ['react-router-dom'],
        },
      },
    },
    sourcemap: true,
    minify: 'esbuild',
  },
  css: {
    modules: {
      localsConvention: 'camelCase',
    },
  },
});

esbuild: The Speed Demon

esbuild was created by Evan Wallace (co-founder of Figma) in 2020. Written in Go, it parallelizes work across CPU cores and avoids the overhead of a JavaScript runtime. The result is build speeds 10-100x faster than JavaScript-based bundlers. esbuild can bundle a large project in under a second where Webpack would take 30+ seconds.

However, esbuild intentionally has a limited plugin API and does not aim to replace Webpack feature-for-feature. It excels as a transpiler and bundler but lacks advanced features like HMR, sophisticated code splitting strategies, and HTML generation. Many tools (including Vite) use esbuild internally while adding higher-level features on top.

Key Features

Configuration Example

// esbuild.config.mjs
import * as esbuild from 'esbuild';

await esbuild.build({
  entryPoints: ['src/index.tsx'],
  bundle: true,
  outdir: 'dist',
  format: 'esm',
  splitting: true,
  minify: true,
  sourcemap: true,
  target: ['es2020'],
  loader: {
    '.png': 'file',
    '.svg': 'file',
  },
  define: {
    'process.env.NODE_ENV': '"production"',
  },
  plugins: [],
});

// Or use the CLI:
// esbuild src/index.tsx --bundle --outdir=dist
//   --format=esm --splitting --minify --sourcemap

Turbopack: The Rust-Powered Next.js Default

Turbopack was announced by Vercel in October 2022 as the successor to Webpack. Written in Rust using the Turbo engine, it uses incremental computation — meaning it only recomputes what has actually changed. Turbopack became the default bundler for Next.js development mode starting with Next.js 15.

Turbopack is designed to handle the largest codebases in the world. Its incremental architecture means that HMR speed does not degrade as your project grows. A 10,000-module app updates just as fast as a 100-module app because only the changed module and its dependents are reprocessed.

Key Features

Pros

Cons

Dev Server Speed Comparison

Development speed is where these tools differ most dramatically. The following benchmarks are based on a React + TypeScript project with approximately 1,000 modules.

Note: esbuild does not include a dev server or HMR out of the box. It is primarily a bundler/transpiler. Turbopack numbers are for Next.js projects only. Benchmarks are approximate and vary based on hardware, project structure, and dependency count.

Production Build Speed Comparison

Production build performance matters for CI/CD pipelines. Here are approximate build times for different project sizes.

Note: Vite production builds use Rollup, which is slower than esbuild but produces more optimized output. Turbopack does not currently support production builds. These numbers include TypeScript transpilation, minification, and asset processing.

Configuration Complexity

One of the biggest differences between these tools is how much configuration they require. Webpack is notoriously config-heavy, while Vite and esbuild aim for sensible defaults.

Webpack: Explicit Configuration

A typical Webpack project requires installing and configuring multiple loaders and plugins. A production-ready webpack.config.js often spans 100-300 lines. You need to explicitly configure TypeScript support (ts-loader or babel-loader + @babel/preset-typescript), CSS processing (css-loader + postcss-loader + MiniCssExtractPlugin), asset handling, dev server, and optimization settings.

# Typical Webpack dependencies
npm install --save-dev webpack webpack-cli webpack-dev-server
npm install --save-dev html-webpack-plugin mini-css-extract-plugin
npm install --save-dev ts-loader css-loader postcss-loader style-loader
npm install --save-dev @babel/core @babel/preset-env @babel/preset-react
npm install --save-dev babel-loader
# Total: 12+ dev dependencies just for the build tool

Vite: Convention Over Configuration

Vite works out of the box with zero configuration for most projects. TypeScript, JSX, CSS Modules, and PostCSS are supported natively. A typical vite.config.ts is 10-30 lines. The only required plugin is framework-specific (e.g., @vitejs/plugin-react).

# Typical Vite dependencies
npm install --save-dev vite @vitejs/plugin-react
# Total: 2 dev dependencies
# TypeScript, CSS Modules, PostCSS — all built-in

esbuild: Minimal API

esbuild has the simplest API — a single function call or CLI command. However, you may need additional tooling for HTML generation, dev server, and HMR. The esbuild API is programmable in JavaScript/Go but lacks the declarative config file pattern.

# Typical esbuild dependencies
npm install --save-dev esbuild
# Total: 1 dev dependency
# But you'll likely need additional tools for a full dev workflow

Turbopack: Zero Configuration (within Next.js)

Turbopack requires no separate configuration — it is enabled automatically in Next.js. Any configuration is done through next.config.js. If you need custom Webpack loaders, many work through the Webpack compatibility layer.

# Turbopack dependencies (via Next.js)
npx create-next-app@latest my-app
# Turbopack is included — no extra installation
# Enable in dev: next dev --turbopack

Plugin Ecosystem Comparison

The plugin ecosystem determines how easily you can extend a build tool to handle your project's specific needs.

Webpack Loaders and Plugins

Webpack has the largest plugin ecosystem in the JavaScript bundler world. With thousands of loaders and plugins available on npm, you can find a solution for virtually any build requirement. The loader/plugin architecture is well-documented and has been refined over a decade. Key examples include: babel-loader, ts-loader, css-loader, sass-loader, less-loader, file-loader, url-loader, HtmlWebpackPlugin, MiniCssExtractPlugin, DefinePlugin, CopyWebpackPlugin, BundleAnalyzerPlugin, and Module Federation Plugin.

Vite Plugins (Rollup-Compatible)

Vite's plugin API is based on Rollup's plugin interface with Vite-specific extensions. This means many existing Rollup plugins work directly with Vite. The Vite plugin ecosystem is growing rapidly, with official plugins for React, Vue, Svelte, and Legacy browser support. Community plugins cover PWA, SSG, component inspection, and more. Creating a Vite plugin is significantly simpler than creating a Webpack loader/plugin pair.

// Example: Custom Vite plugin
export default function myPlugin() {
  return {
    name: 'my-plugin',
    // Rollup-compatible hooks
    resolveId(source) {
      if (source === 'virtual-module') {
        return source;
      }
    },
    load(id) {
      if (id === 'virtual-module') {
        return 'export default "Hello from virtual module"';
      }
    },
    // Vite-specific hooks
    configureServer(server) {
      server.middlewares.use((req, res, next) => {
        // Custom middleware
        next();
      });
    },
    transformIndexHtml(html) {
      return html.replace(
        '</head>',
        '<script>console.log("injected")</script></head>'
      );
    },
  };
}

esbuild Plugins

esbuild's plugin API is intentionally minimal and focused. Plugins can intercept module resolution (onResolve) and loading (onLoad), but cannot modify the bundling or optimization phases. This keeps esbuild fast but limits extensibility. The plugin ecosystem is small compared to Webpack or Vite.

// Example: esbuild plugin
const envPlugin = {
  name: 'env',
  setup(build) {
    // Intercept import paths starting with "env:"
    build.onResolve({ filter: /^env:/ }, (args) => ({
      path: args.path,
      namespace: 'env-ns',
    }));
    // Load the intercepted paths
    build.onLoad({ filter: /.*/, namespace: 'env-ns' }, () => ({
      contents: JSON.stringify(process.env),
      loader: 'json',
    }));
  },
};

await esbuild.build({
  entryPoints: ['src/index.ts'],
  bundle: true,
  outfile: 'dist/bundle.js',
  plugins: [envPlugin],
});

Framework Support Comparison

Different build tools have varying levels of support for popular frameworks. Here is the compatibility matrix.

Migration Guide: Webpack to Vite

Vite is the most common migration target for Webpack users. Here is a step-by-step guide with common gotchas.

Step-by-Step Migration

Step 1: Install Vite and framework plugin

npm install --save-dev vite @vitejs/plugin-react
# Remove Webpack dependencies
npm uninstall webpack webpack-cli webpack-dev-server
npm uninstall html-webpack-plugin mini-css-extract-plugin
npm uninstall babel-loader ts-loader css-loader style-loader

Step 2: Create vite.config.ts

// vite.config.ts
import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';

export default defineConfig({
  plugins: [react()],
  resolve: {
    alias: {
      '@': '/src',  // Vite uses URL-style paths
    },
  },
});

Step 3: Move index.html to project root

Vite uses index.html as the entry point (not a Webpack plugin). Move it from public/index.html to the project root and add a script tag pointing to your entry file:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8" />
  <meta name="viewport" content="width=device-width, initial-scale=1.0" />
  <title>My App</title>
</head>
<body>
  <div id="root"></div>
  <!-- This is the key difference from Webpack -->
  <script type="module" src="/src/main.tsx"></script>
</body>
</html>

Step 4: Update package.json scripts

{
  "scripts": {
    "dev": "vite",
    "build": "tsc && vite build",
    "preview": "vite preview"
  }
}

Step 5: Update environment variables

Vite uses import.meta.env instead of process.env. Variables must be prefixed with VITE_ instead of REACT_APP_:

// Before (Webpack / CRA)
const apiUrl = process.env.REACT_APP_API_URL;

// After (Vite)
const apiUrl = import.meta.env.VITE_API_URL;

Common Migration Gotchas

Decision Matrix: Which Build Tool to Choose

The right tool depends on your project type, team size, and priorities. Here is a practical decision matrix.

For most new projects in 2025, Vite is the default recommendation. It offers the best balance of development speed, production output quality, and ecosystem support. Use Webpack only if you need Module Federation or are maintaining an existing Webpack project. Use esbuild when raw build speed is the top priority and you do not need a dev server. Use Turbopack if you are building with Next.js.

Frequently Asked Questions

Is Vite faster than Webpack?

Yes, Vite is significantly faster than Webpack for development. Vite's dev server starts in under a second regardless of project size because it uses native ES modules instead of bundling. HMR updates take 20-50ms in Vite versus 200-500ms in Webpack. For production builds, Vite (using Rollup) is about 2-3x faster than Webpack. However, if you enable Webpack 5's persistent filesystem cache, the gap narrows for subsequent builds.

Can esbuild replace Webpack completely?

For most web applications, no. esbuild lacks a built-in dev server, HMR, HTML generation, and has a limited plugin API. It is best used as a transpiler/bundler embedded in higher-level tools (like Vite) or for building Node.js libraries and simple scripts where you do not need a dev server. For complex web applications with code splitting, multiple entry points, and framework-specific transforms, Vite or Webpack remain better choices.

Should I migrate from Webpack to Vite?

It depends on your situation. If your team frequently complains about slow dev server startup or HMR, migrating to Vite can dramatically improve developer experience. The migration is straightforward for most React, Vue, and Svelte projects. However, if your Webpack setup is heavily customized with many loaders and plugins, the migration may require significant effort. Start by evaluating whether your Webpack plugins have Vite equivalents.

What is Turbopack and when should I use it?

Turbopack is a Rust-based bundler built by Vercel specifically for Next.js. It uses incremental computation to maintain consistent HMR speed regardless of project size. As of early 2025, Turbopack is the default dev bundler for Next.js but does not support production builds yet. You should use it if you are building a Next.js application — it is enabled automatically. It is not available as a standalone tool for non-Next.js projects.

Why does Vite use Rollup for production instead of esbuild?

Although esbuild is faster, Rollup produces more optimized output for production bundles. Rollup has better tree shaking, more mature code splitting with precise chunk control, and a richer plugin ecosystem for production transforms. Vite's philosophy is to use the fastest tool for each context: esbuild for development (where speed matters most) and Rollup for production (where output optimization matters most). The Vite team has been working on Rolldown, a Rust-based Rollup replacement that aims to combine esbuild's speed with Rollup's optimization quality.
