esbuild-node-builtins

library0.1.0jsnpmunverified

esbuild-node-builtins is a plugin for esbuild that provides polyfilled Node.js built-in modules (e.g., 'fs', 'path', 'crypto') for browser or other non-Node environments. Version 0.1.0 is the initial stable release, with no further updates or release cadence documented. It wraps browserify's 'node-libs-browser' to polyfill core modules, enabling bundling of Node-centric code for the browser with esbuild. Unlike esbuild's native 'platform: node', this plugin actually inlines polyfills; it is a simple integration but has no active maintenance and may be superseded by esbuild's own node polyfills or other plugins like 'esbuild-plugin-polyfill-node'.

Code

Verified usage

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

nodeBuiltIns

✓ const { nodeBuiltIns } = require('esbuild-node-builtins')

✗ const nodeBuiltIns = require('esbuild-node-builtins')

Default export is not available; must destructure the named export 'nodeBuiltIns'. CJS only, no ESM export.

nodeBuiltIns

✓ import { nodeBuiltIns } from 'esbuild-node-builtins'

✗ import nodeBuiltIns from 'esbuild-node-builtins'

The package does not export a default, so named import is required. However, the package has no 'module' entry and may not work in ESM contexts; prefer require().

nodeBuiltIns

✓ const { nodeBuiltIns } = await import('esbuild-node-builtins')

✗ const { default: nodeBuiltIns } = await import('esbuild-node-builtins')

Dynamic import works but only the named export is available; no default export.

Shows how to require and use the nodeBuiltIns plugin in an esbuild build script for browser bundling.

const { build } = require('esbuild'); const { nodeBuiltIns } = require('esbuild-node-builtins'); build({ entryPoints: ['./app.js'], bundle: true, outfile: './out.js', platform: 'browser', plugins: [nodeBuiltIns()], }).catch(() => process.exit(1));

Debug

Known issues

deprecatedPackage is no longer maintained; use esbuild-plugin-polyfill-node or esbuild's native node polyfill via platform: 'node'

fix

Switch to 'esbuild-plugin-polyfill-node' (npm) or use esbuild's native handling by setting platform: 'node'.

affects: >=0.0

gotchaCannot use ES module import syntax; package requires CommonJS require()

fix

Use require() or dynamic import() with .mjs extension / type: module? Not recommended.

affects: >=0.0

gotchaNot all Node.js built-ins are polyfilled; relies on node-libs-browser which may be incomplete

fix

Test your code thoroughly; consider contributing to node-libs-browser or using a more comprehensive polyfill.

affects: >=0.0

Errors

Common errors & fixes

Cannot find module 'esbuild-node-builtins'

Package not installed or missing from node_modules

fix

Run 'npm install esbuild-node-builtins' or 'yarn add esbuild-node-builtins'

TypeError: (intermediate value).nodeBuiltIns is not a function

Wrong import style: using default import instead of named destructuring

fix

Use 'const { nodeBuiltIns } = require("esbuild-node-builtins")' (note curly braces)

Error: Could not resolve 'fs' (or similar built-in module)

nodeBuiltIns plugin not registered in esbuild's plugins array

fix

Add nodeBuiltIns() to the plugins array and ensure esbuild is configured with platform: 'browser'
