Visually configure esbuild bundler with JSX/TypeScript/code splitting/minification — generate build scripts in one click
Zero Dependencies · Works OfflineThe esbuild Config Generator is a free online tool that helps developers quickly create esbuild build configurations. Instead of manually writing complex build scripts, you can visually configure all options and generate production-ready esbuild configuration code instantly. All processing happens locally in your browser — no data is uploaded to any server.
1. Set the entry point path and output directory.
2. Choose bundle format (ESM/CJS/IIFE) and target platform (Browser/Node.js).
3. Enable desired features: minification, source maps, tree shaking, code splitting, etc.
4. For JSX support, select the runtime mode and configure factory functions.
5. Click "Generate Config" to get your esbuild script, then copy it to your project.
Quickly set up esbuild build pipelines to replace Webpack and achieve 10-100x faster builds. Ideal for teams prioritizing developer experience.
Use esbuild to bundle npm packages with dual ESM and CJS output, combined with tree shaking for minimal package size.
Bundle TypeScript projects into single files for deployment, reducing node_modules dependencies and simplifying production environments.
esbuild was created by Evan Wallace (Figma co-founder) in 2020, written in Go. Its core advantage lies in leveraging Go's native concurrency to parallelize parsing, transformation, and code generation. esbuild also powers Vite's development server. While esbuild's plugin ecosystem is less mature than Webpack's, it's sufficient for most projects. esbuild supports incremental builds and watch mode, and can be combined with file watchers like chokidar for automatic rebuilds.
esbuild is an extremely fast JavaScript bundler and minifier written in Go. It's 10-100x faster than traditional tools like Webpack and Rollup, supporting JSX, TypeScript, code splitting, tree shaking, and other modern frontend features.
esbuild is written in Go, leveraging native multi-threaded parallel processing. Unlike JavaScript-based tools, esbuild is optimized for performance from the ground up, compiled to machine code without going through the V8 engine.
esbuild is 10-100x faster than Webpack but has a less mature plugin ecosystem. Webpack offers more flexible configuration and a richer plugin system for complex projects. esbuild is ideal for projects prioritizing build speed, and also serves as Vite's underlying bundler.
Yes. esbuild has built-in TypeScript transformation and can handle .ts and .tsx files without additional configuration. However, esbuild only does syntax transformation, not type checking — use tsc --noEmit for type validation.
Absolutely safe! All configuration generation happens locally in your browser. No data is sent to any server, and no personal information is collected.
