browserify-swap build status

swap/swäp/ - an act of exchanging one thing for another

A transform that swaps out modules according to a config in your package.json selected via an environment variable.

package.json

{
  "browserify": {
    "transform": [ "browserify-swap" ]
  },
  "browserify-swap": {
    "@packages": [ "hyperwatch" ],
    "dev": {
      ".*node_modules\/hyperwatch\/\\S+\\.js$": "./swap/some-hyperwatch-swap.js",
      "util.js$": "myutil"
    },
    "test": {
      "util.js$": "test-util"
    }
  }
}
  • each file matcher (i.e. 'util.js$') is a regular expression
  • in order to swap files of dependencies the browserify-swap transform needs to be injected into its package, therefore indicate those packages via the @packages array
BROWSERIFYSWAP_ENV='dev' browserify . -o bundle.js
