babel-plugin-require-context-hook-babel7

library1.0.0jsnpmunverified

A Babel plugin that replicates Webpack's `require.context` functionality for use with `babel-register`. Version 1.0.0 is stable; the plugin rewrites `require.context()` calls to use a global polyfill that must be registered at runtime via `require('babel-plugin-require-context-hook/register')()`. It depends on `@babel/core ^7.2.2`. This is a minimal, focused alternative to full Webpack configurations for projects needing dynamic require in Node.js.

Verified usage

ContextPolyfill

✓ require('babel-plugin-require-context-hook/register')()

✗ import 'babel-plugin-require-context-hook/register'

The register script must be required and called as a function. ES imports will not invoke the function.

require.context

✓ require.context(directory, useSubdirectories, regExp)

✗ require.context(directory)

All three arguments are required in the polyfill; the original Webpack signature allows omitting. The plugin rewrites calls to include __dirname.

babel-plugin syntax

✓ "plugins": ["require-context-hook"]

✗ "plugins": ["babel-plugin-require-context-hook"]

In .babelrc, use the short name (without 'babel-plugin-') to avoid double prefixing.

Demonstrates setup: add plugin to .babelrc, register polyfill at entry point, then use require.context with three arguments.

// .babelrc file { "plugins": ["require-context-hook"] } // entry.js - must run before any module that uses require.context require('babel-plugin-require-context-hook/register')(); // usage in a module const modules = require.context('./components', true, /\.js$/); modules.keys().forEach(key => { const mod = modules(key); console.log('Loaded module:', mod); }); // Then run with: node -r @babel/register entry.js

Debug

Known issues

gotchaRegister function must be called before any require.context usage. If called after, the global polyfill is not set.

fix

Call require('babel-plugin-require-context-hook/register')() at the very top of your entry file, before requiring any module that uses require.context.

affects: >=1.0.0

gotchaMissing third argument (regExp) in require.context call will cause a runtime error because the polyfill expects exactly three arguments.

fix

Always provide all three arguments: require.context(directory, useSubdirectories, regExp). If you don't care about a filter, use /^./.

affects: >=1.0.0

breakingThe 'babel-plugin-' prefix in .babelrc plugins list may cause double registration and break plugin detection.

fix

Use the short plugin name: "require-context-hook" without the 'babel-plugin-' prefix.

affects: <=1.0.0

Errors

Common errors & fixes

Error: require.context is not a function

The register script has not been called, or was called after modules using require.context were loaded.

fix

Add require('babel-plugin-require-context-hook/register')() at the very top of your entry file, before any other require calls.

TypeError: Cannot read property 'replace' of undefined

The third argument (regExp) to require.context is missing; the polyfill regex conversion expects a regex string.

fix

Provide a third argument to require.context, e.g., require.context('./', true, /\.js$/).
