Global Callback when all scripts have finished Loading?

[jonnyreeves]

I'm looking for a way to get a global callback when all of my scripts have finished loading asynchronously, is this possible?

There is a global callback after a timeout, but I'm guessing that's not what you want. You could always monitor nbl.q to see if all scripts have loaded, or define a callback function for every script that checks nbl.q? I'll put it on the list for the next version, thanks!

Just to be sure, how are you using NBL, perhaps I can come up with a solution in the meantime?

Heya, thanks for replying. I was using NBL to load our app's js libraries at runtime; however, once all libraries had finished loading I needed to execute one last chunk of code to kick the whole thing off. At first I was using a sequence similar to this:

nbl.l([ 'script1.js', 'script2.js', 'script3.js', onAllScriptsLoaded ]);

However the onAllScriptsLoaded callback was being fired after script3.js completed which lead to a race condition. What I was really looking for was a way to say "once all these scripts have finished, execute this callback", perhaps the syntax could look something like this:

nbl.l([ 'script1.js', 'script2.js', 'script3.js' ]).onAllComplete(function () { console.log('all scripts loaded!') });

I'm afraid I had to switch to LAB.js because of this missing feature, however, my first choice was NBL due to its compact size (I need to inline the code into my project's bootstrap).

I get it, it' a fair point. I haven't run into this issue myself, but in retrospect, I don't understand why I did not put in that feature in the first place! This is going to the top of the list, thanks. Would you like me to contact you when I've fixed this?

[jonnyreeves]

Yes please; although if I get some free time I will have a stab at writing the code in a fork :)

Thanks for your hard work on this library and your swift replies.
