Browser-side require() for js directories and npm modules

Package Exports

  • browserify
  • browserify/builtins/events
  • browserify/package.json

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (browserify) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Browserify

Browser-side require() for your node modules and npm packages

Browserify bundles all of your javascript when your server fires up at the mount point you specify.

browserify!

More features:

  • recursively bundle dependencies of npm modules

  • uses es5-shim for browsers that suck

  • filters for {min,ugl}ification

  • coffee script works too!

  • bundle browser source components of modules specially with the "browserify" package.json field

examples

simple example

server.js

var connect = require('connect');
var server = connect.createServer();

server.use(connect.static(__dirname));
server.use(require('browserify')({
    base : __dirname + '/js',
    mount : '/browserify.js',
    filter : require('jsmin').jsmin,
}));

server.listen(9797);
console.log('Listening on 9797...');

js/foo.js

var bar = require('./bar');
var baz = require('./baz');

module.exports = function (x) {
    return x * bar.coeff(x) + baz.wowsy(x);
};

js/bar.js

exports.coeff = function (x) {
    return Math.log(x) / Math.log(2) + 1;
};

js/baz.coffee

exports.wowsy = (beans) ->
    beans * 3 - 2

methods

var browserify = require('browserify');

browserify(opts)

Return a middleware that will host up a browserified script at opts.mount or "/browserify.js" if unspecified. All other options are passed to browserify.bundle(opts) to generate the source.

browserify.bundle(base)

browserify.bundle(opts)

Return a string with the bundled source code given the options in opts:

base

Recursively bundle all .js and .coffee files.

Base can be a directory, an Array of directories, or an object that maps names to directories such that require('name/submodule') works.

If there is a package.json at the base directory it will be read according to the package.json procedure below.

name

Preface the files in base with this name.

main

Map require(name) for the name field to this file.

shim

Whether to include es5-shim for legacy javascript engines.

True if unspecified.

require

Bundle all of these module names and their dependencies.

If the name has a slash in it, only that file will be included, otherwise all .js and .coffee files which are not in the test directory and are not binaries will be bundled into the final output.

package.json

During bundling the package.json of a module or base directory will be read for its name and main fields, which will be used unless those fields are defined in opts.

If the package.json has a "browserify" field, its contents will take precedence over the standard package.json contents. This special field is meant for packages that have a special browser-side component like dnode and socket.io. If a main is specified in a "browserify" hash and no "base" is given, only that "main" file will be bundled.

compatability

process

Browserify exports a faux process object with these attributes:

  • nextTick(fn) - does setTimeout(fn, 0)
  • title - set to 'browser' for browser code, 'node' in regular node code

events

You can require('events').EventEmitters just like in node.js code.

path

The posix functions from the path module have been included except for exists() and existsSync(). Just require('path')!

__dirname

The faux directory name, scrubbed of true directory information so as not to expose your filesystem organization.

__filename

The faux file path, scrubbed of true path information so as not to expose your filesystem organization.

protips

  • npm install jquery-browserify to have npm and browserify handle your jquery deployment!
