nw-dev

A drop-in library for nw.js development

• Live-reloads upon save

• Opens devtools when you press F12

• Opens devtools upon error

• Sets window.CRASHED upon error, so you can stop an animation loop for example and only get one error

• Clears require cache, so reloading works with modules

• When loaded in a browser (non-nw.js), it only tries to do error handling

install nw-dev

npm i nw-dev --save-dev

Put this script before any other scripts (that you're developing, at least):

<script src="node_modules/nw-dev/lib/dev.js"></script>

Or just download lib/dev.js and include it:

<script src="lib/dev.js"></script>

my window annoyingly asserts focus when reloading

(This can be especially annoying if your editor autosaves!)

You probably have your app set up to show itself once it finishes loading.

That's good, but you're calling win.show() which focuses the window.

Do this (CoffeeScript):

win.show() unless win.shown
win.shown = yes

Or this (JavaScript):

if(!win.shown){
    win.show();
    win.shown = true;
}

(Now your autosaving workflow is once again beneficial!)
