source-map plugin for Browserify

Cross-Platform Compatibility Build Status

npm License Buy us a tree

The default sourcemap that Browserify generates uses paths that are relative to the current directory, which may not always be what you want. This plugin lets you change the relative path, or use absolute paths.

This plugin was inspired by browserify-sourcemap-root-transform, so check that one out if this one doesn't meet your needs.

Install using npm:

npm install @jsdevtools/sourcemapify


Command Line

Use Browserify's sub-argument command-line syntax, like this:

browserify -p [ @jsdevtools/sourcemapify --root "../../" ] --debug

Browserify API

Use the plugin programmatically like this: full example

var browserify = require('browserify');
var sourcemapify = require('@jsdevtools/sourcemapify');

browserify({debug: true})
  .plugin(sourcemapify, {base: 'www/js'})
  .pipe(fs.createWriteStream('www/js/bundle.js', 'utf8'));


The following options can be set via the API or command-line:

root (string)

The root path for all files in the source map. It can be an absolute or relative path. This string will be prepended as-is to each file path.

base (string)

The base path of the bundle (i.e. the bundle file's directory, relative to cwd). This path will be used to determine the relative path of each file. It can be an absolute or relative path.
