library0.25.2-0.0.6jsnpmunverified

JavaScript bundler and minifier with extreme speed through Go-based parallelism. Version 0.25.2 (pre-release) supports ESM, CJS, TypeScript, CSS bundling, and code splitting. Unlike Webpack or Rollup, esbuild is designed for rapid builds (10-100x faster) but lacks plugin ecosystem depth and advanced tree-shaking. Weekly releases.

Install & Compatibility

Where this runs

No compatibility data collected yet for this library.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

build

✓ import { build } from 'esbuild'

✗ const { build } = require('esbuild')

Default import (e.g., import esbuild from 'esbuild') is not available; use named import.

transform

✓ import { transform } from 'esbuild'

✗ import { transformSync } from 'esbuild'

Use async `transform` for Promise-based API; `transformSync` exists but is named differently.

context

✓ import { context } from 'esbuild'

✗ const context = require('esbuild').context

Available since v0.16 for incremental builds; use with async/await.

metafile

✓ import type { Metafile } from 'esbuild'

✗ import { Metafile } from 'esbuild'

Metafile is a type only; use import type for TypeScript.

Bundles an entry point with source maps, targeting Node 18 ESM.

import { build } from 'esbuild'; import { promises as fs } from 'fs'; async function bundle() { const result = await build({ entryPoints: ['app.js'], bundle: true, outfile: 'out.js', platform: 'node', target: ['node18'], format: 'esm', sourcemap: true, }); console.log('Build succeeded:', result.errors.length === 0); } bundle().catch(console.error);

Debug

Known issues

breakingesbuild v0.17 removed the 'define' option for simple string replacement; use 'define' for JSON-compatible values only.

fix

Use 'define' with JSON.stringify values or use the 'inject' plugin for complex replacements.

affects: >=0.17

gotchaThe 'target' option affects syntax transformation only, not polyfills; esbuild does not inject polyfills.

fix

Use with core-js or a polyfill service for older targets.

affects: *

deprecatedThe 'banner' and 'footer' options are deprecated in favor of 'inject' or 'plugins'.

fix

Use the 'inject' feature or write a plugin to prepend/append content.

affects: >=0.14

gotchaCSS bundling does not support all CSS features (e.g., @import with url() resolution is limited).

fix

Consider using postcss with esbuild for advanced CSS processing.

affects: *

breakingIn v0.16, the 'incremental' option was replaced by the 'context' API.

fix

Use 'context' for incremental builds: const ctx = await context({...}); await ctx.rebuild(); await ctx.dispose();

affects: >=0.16

Errors

Common errors & fixes

Cannot find module 'esbuild'

Missing npm install

fix

npm install esbuild

Build failed with 1 error: error: The define option must be an object

Provided string to 'define' instead of object

fix

Use define: { 'process.env.NODE_ENV': '"production"' }

error: No loader is configured for ".vue" files

esbuild natively does not handle Vue files

fix

Install a plugin like esbuild-plugin-vue or use Vite instead.

TypeError: esbuild.build is not a function

Wrong import style (tried default import)

fix

Use import { build } from 'esbuild'; not import esbuild from 'esbuild';
