watch mode for browserify builds
Update any source file and your browserify bundle will be recompiled on the spot.
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:
$ watchify browser.js -d -o static/bundle.js -v
610598 bytes written to static/bundle.js
610606 bytes written to static/bundle.js
610597 bytes written to static/bundle.js
610606 bytes written to static/bundle.js
610597 bytes written to static/bundle.js
610597 bytes written to static/bundle.js
All the bundle options are the same as the browserify command except for -v
.
var watchify = require('watchify')
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.
When the bundle changes, emit the array of bundle ids
that changed.
With npm do:
$ npm install -g watchify
to get the watchify command and:
$ npm install watchify
to get just the library.
