Consider integrating with fastdom somehow

The fastdom project does a very similar read/write distinction, maybe there's an opportunity to have a fastdom debug mode, where nope.js is used to throw when dumb things are happening.

@wilsonpage, you might find this interesting.

nope-js looks like an interesting project, how is it supposed to be used?

[dglazkov]

The main premise is that this library emphasizes bad ideas by throwing exceptions. It's sort of like a debug mode for your web app.

Currently, I have two ideas for deployment:

1. As an extension (on/off button), dynamically injected into the page -- to help with small-scale deployments or checking existing sites for badness.
2. As a development-time check that you only don't use in production.

Who is responsible for setting the lifeCycleMode?

[dglazkov]

You still have to do that yourself, sadly. In your case, you'll flip it just before running the batch of "reads"

[wilsonpage]

Ah I get ya! So using nope-js would throw if user tried to do a 'read' in a 'write' callback?

[dglazkov]

Yes. For example, currently, if you access element.offsetLeft in "write", nope will throw.

I am currently compiling a list of layout triggers (DOM props/methods that will cause synchronous layout/reflow) for Blink here: https://github.com/dglazkov/nope-js/blob/master/nope.js#L12
