requiremap

A browserify transform stream for aliasing require statements. You can use it to write your own transforms for things like custom extensions and module resolution.

Installation

npm install requiremap

Usage

require('requiremap')(map)

Returns a browserify transform that calls map(file, node, update) for each require detected.

  • file is the absolute path to the file requiring the module.
  • node is an AST node from falafel. In most cases, you should be fine getting node.value for the module name.
  • update(err, updated) is a callback you should call with the new string to place in the require statement - this must be called. If you don't want to update it, just use update() without any arguments.
var browserify = require('browserify')
var requiremap = require('requiremap')
var b = browserify()

b.add(__dirname + '/src/index.js')

// "async" -> "./a.js"
// "beefy" -> "./b.js"
// "./src" -> "./src"
b.transform(requiremap(function(file, node, update) {
  if (node.value[0] === '/') return update()
  if (node.value[0] === '.') return update()
  update(null, './' + node.value.slice(0, 1))
}))

b.bundle.pipe(process.stdout)
