Examples

Runs make when a file changes:

$ watch make

Runs make before monitoring (-b), then runs node server, a long-running process (-r):

$ watch -rb make node server

Runs make then reloads (-l) browser when files of type .js or .css change (-m):

$ watch -lm *.{js,css} make

The above method requires this script tag:

<script src="http://localhost:3003/reload.js"></script>

If you use Components you can add it in like this:

"development": {
  "stagas/watch-js": "*"
}

Then you can do require('stagas-watch-js') in your development files.

Now, in conjuction with watch -l make, when you save a file in your editor it will run make and reload your browser automatically.

Combinations possible:

$ watch -lrb "make clean build" node server
