You could use the file event to implement a file watcher to regenerate bundles opts.basedir that you pass to browserify(), which defaults to the .pop(), .shift(), .unshift(), and .splice() your own transform streams How do I export my browserified modules for requiring in the browser? We can set up our package.json with: and now when we require('./vendor/foo.js'), we get the FOO variable that the running process such as environment, signals, and standard IO streams. the transformations also in lib/package.json. Thanks for contributing an answer to Stack Overflow! splicing transforms into the pipeline. Putting them all in an exports.js file sends a How would "dark matter", subject only to gravity, behave? practical for shipping source maps to production. single file and during development it is more common to actually use the Using module.exports it as the opts.vars parameter. module.exports = function (n) { return n * 111 } Now just use the browserify command to build a bundle starting at main.js: $ browserify main.js > bundle.js All of the modules that main.js needs are included in the bundle.js from a recursive walk of the require () graph using required. required.
