Send a diff rather than a whole file about chrome-devtools-autosave

[NV]

Use either kpdecker/jsdiff or Google Diff Match Patch. The latter does smart char-by-char diff.

Diffs work. @drewcovi check it out!

I haven’t released the extension yet, it needs more testing, so load it from the repo.

Wo0t!

Guys — is there a real-world use case where this is useful? I'm implementing a similar functionality in LiveReload, and I wonder if this complication makes any sense.

I would say: if you're editing a stale file, you already have a problem, and we should simply avoid that (perhaps by comparing the content on load, and doing resource.setContent/reload to update when needed).

And if you have multiple people editing the same physical file, you already have a very big problem.

Diffs work significantly faster over slow internet connection. It does make difference when you edit 2 megabyte concatenated JS file.

I believe it is possible to use DevTools Autosave with LiveReload to keep files always up to date. Although, I haven’t actually tried it.
