Browserify ES6 Module Transpiler

0.1.1 verified Fri May 01 auth: no javascript deprecated

A Browserify transform that compiles ES6 module syntax (import/export) to CommonJS using the ES6 Module Transpiler. Version 0.1.1 is the latest release; no updates since 2014. This project is experimental (WIP) and superseded by Babel. Designed for early adopters of ES6 modules in Browserify builds, but now obsolete. Not recommended for new projects.

Common errors

error TransformError: .../node_modules/browserify-es6-modules/index.js: ... is not a function ↓

cause The transform is applied incorrectly (e.g., calling it as a function instead of passing a string).

fix

Use b.transform('browserify-es6-modules') not b.transform(require('...')).

error Module not found: es6-module-transpiler not installed ↓

cause Missing peer dependency es6-module-transpiler.

fix

Run: npm install es6-module-transpiler

Warnings

deprecated This package is unmaintained and superseded by Babel. Do not use in new projects. ↓

fix Use Babel with babelify transform instead.

breaking Experimental (WIP) – may not correctly transpile all ES6 module syntax. ↓

fix Test your code thoroughly or switch to a mature alternative.

gotcha Requires es6-module-transpiler to be installed separately; not listed as a dependency in package.json. ↓

fix Explicitly install es6-module-transpiler alongside this package.

Install

npm install browserify-es6-modules

yarn add browserify-es6-modules

pnpm add browserify-es6-modules

Imports

default export (transform function)
wrong
```
import transform from 'browserify-es6-modules';
```
correct
```
module.exports = require('browserify-es6-modules');
```
Package does not support ES modules; use CommonJS require.
Transform usage in package.json or gulp
wrong
```
browserify().transform(require('browserify-es6-modules'));
```
correct
```
browserify().transform('browserify-es6-modules');
```
Browserify resolves transform names; passing function may cause issues.

Stream interface

wrong

var tr = new require('browserify-es6-modules')();

correct

var through = require('through2'); var tr = through();

Uses through2 internally; not instantiated directly.

Quickstart

Shows how to apply the transform in a Browserify build script.

// Install: npm install browserify-es6-modules es6-module-transpiler
// In your build script:
var browserify = require('browserify');
var b = browserify();
b.transform('browserify-es6-modules');
b.add('./entry.js');
b.bundle().pipe(process.stdout);
// Then run the script with Node.
