watchify

watch mode for browserify builds

Update any source file and your browserify bundle will be recompiled on the spot.

example

Use watchify with all the same arguments as browserify except that -o is mandatory:

$ watchify main.js -o static/bundle.js

Now as you update files, static/bundle.js will be automatically re-compiled on the fly.

You can use -v to get more verbose output to show when a file was written and how long the bundling took (in seconds):

$ watchify browser.js -d -o static/bundle.js -v
610598 bytes written to static/bundle.js  0.23s
610606 bytes written to static/bundle.js  0.10s
610597 bytes written to static/bundle.js  0.14s
610606 bytes written to static/bundle.js  0.08s
610597 bytes written to static/bundle.js  0.08s
610597 bytes written to static/bundle.js  0.19s

usage

All the bundle options are the same as the browserify command except for -v.

methods

var watchify = require('watchify')

var w = watchify(opts)

Create a browserify bundle w from opts.

w is exactly like a browserify bundle except that caches file contents and emits an 'update' event when a file changes. You should call w.bundle() after the 'update' event fires to generate a new bundle. Calling w.bundle() extra times past the first time will be much faster due to caching.

w.close()

Close all the open watch handles.

events

w.on('update', function (ids) {})

When the bundle changes, emit the array of bundle ids that changed.

install

With npm do:

$ npm install -g watchify

to get the watchify command and:

$ npm install watchify

to get just the library.
