bit-loader-builtins

library2.0.2jsnpmunverified

A loader plugin for bit-bundler that resolves Node.js built-in modules (like 'fs', 'path', 'http') and provides browser-compatible shims using browserify's builtins. Version 2.0.2 is the latest stable release, though the project appears to be in maintenance mode with no recent updates. Key differentiator: it seamlessly integrates with bit-bundler to handle Node.js globals (__dirname, __filename) and built-in modules during browser bundling, leveraging browserify's established polyfills.

Verified usage

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

default

✓ import builtins from 'bit-loader-builtins'

✗ const builtins = require('bit-loader-builtins')

The package exports a single function as default. ESM import is recommended for modern projects.

Creates a bit-bundler Bundle and registers the builtins plugin to handle Node.js built-ins and globals.

import builtins from 'bit-loader-builtins'; import { Bundle } from 'bit-bundler'; const bundle = new Bundle(); bundle.loader(builtins()); // Now bundle can resolve 'fs', 'path', etc. and replace __dirname/__filename

Debug

Known issues

gotchaThe package relies on browserify's builtins which may not cover all Node.js modules or may have incomplete polyfills.

fix

Test bundling of target modules thoroughly; avoid relying on unsupported builtins like 'cluster' or 'child_process'.

affects: all

deprecatedbit-bundler itself is deprecated or no longer actively maintained, making this plugin of limited use.

fix

Consider migrating to a modern bundler like Webpack, Rollup, or esbuild which have built-in Node.js polyfill support.

affects: >=2.0.1

gotcha__dirname and __filename shimming may not work correctly in all scenarios if the module resolution is not properly set.

fix

Ensure bit-bundler is configured to handle the 'builtins' loader plugin correctly. Verify the bundle output for expected values.

Errors

Common errors & fixes

Module not found: Can't resolve 'fs' in ...

bit-loader-builtins not registered with bit-bundler or not installed.

fix

Run 'npm install bit-loader-builtins' and add 'bundle.loader(builtins())' to your bit-bundler setup.

TypeError: builtins is not a function

Incorrect import: using default import but wrong syntax or missing default export.

fix

Use 'import builtins from 'bit-loader-builtins'' (ESM) or 'const builtins = require('bit-loader-builtins').default' (CJS).

Cannot resolve module 'path'

The builtins plugin is not applied or bit-bundler is not configured to use it.

fix

Double-check that bit-loader-builtins is installed and the loader is added to the bundle instance before bundling.
