  • a function that takes a filename and returns a boolean
  • a string that must occur verbatim in the filename
  • a regex that must match the filename
  • an array of valid filters

It returns a browserify transfom.

Example usage

To run envify with different environments for different parts of the project (where b is a browserify instance):

var filterify = require('filterify');
var envify = require('envify/custom');

b.transform(filterify({
  filter: '/prod_mode/',
  transform: envify({
    NODE_ENV: 'production'
  })
}));
b.transform(filterify({
  filter: '/dev_mode/',
