provide a specif builtin version

Hi, is there any chance to specify a specific version of a builtin?
I need to create a bundle which uses [email protected]
thanks

That version of buffer is extremely old…do you need to support IE6 or something? 😕

If you install your desired version using npm, you can use the -r flag to override any dependency by name.

browserify -r buffer/:buffer main.js

or with the API:

browserify('main.js')
  .require('buffer/', { expose: 'buffer' })

The trailing / is important: it forces the resolver to look at the files and dependencies in your project instead of at node.js core modules.

Hi @goto-bus-stop

thanks for the support.
I ended up doing something similar:

const browserify = require('browserify')
const watchify = require('watchify')
const errorify = require('errorify')
const fs = require('fs')

const b = browserify('./src/index.js', {
  builtins: {
    buffer: require.resolve('buffer/'),
    _process: require.resolve('process/browser'),
    events: require.resolve('events/'),
    util: require.resolve('util/util.js'),
    stream: require.resolve('stream-browserify'),
    timers: require.resolve('timers-browserify'),
    string_decoder: require.resolve('string_decoder/')
  },
  standalone: 'lib',
  plugin: process.env.NODE_ENV ? [watchify, errorify] : []
})

const bundle = () => {
  b.bundle()
    .on('error', console.error)
    .pipe(fs.createWriteStream('dist/index.js'))
}

if (process.env.NODE_ENV) {
  b.on('update', bundle)
}

bundle()

it is something similar to what you proposed I guess
