Notes on streaming JS & long-term code compilation caching in Chrome

V8 Optimisations to enable fast page startup

As mentioned in our Chromium blog post, Chrome 41 introduces support for streaming parsing of JavaScript files using the async or defer attributes. This is where the V8 parser will parse any incoming JavaScript piece-by-piece so the compiler can immediately begin compiling the AST when script loading has completed. This lets us do something useful while waiting for the page to load. Compare:

This means parsing can be removed from the critical path when loading up the page. In these cases such scripts are parsed on a separate thread as soon as the download begins, allowing parsing to complete very soon after the download has completed (milliseconds), leading to pages (potentially) loading much faster.

2015-01-29 Unofficial Relay FAQ

Compilation of questions and answers about Relay from React.js Conf.

Disclaimer: I work on Relay at Facebook. Relay is a complex system on which we're iterating aggressively. I'll do my best here to provide accurate, useful answers, but the details are subject to change. I may also be wrong. Feedback and additional questions are welcome.

Possibly Unhandled Rejection NodeJS Promise Hook

###Unhandled Rejection Tracking

Several promise libraries such as bluebird and when as well as some native promise implementations offer potentially unhandled rejection tracking. This means that the following:

Promise.reject(new Error("err")); // never attach a `catch`

browserify for webpack users

There's been a strange explosion in misinformation about browserify recently, particularly in comparisons to webpack.

Generally speaking, most of this confusion stems from how webpack is more willing to pull features into its core to ease discoverability while browserify is more likely to push features out to userland instead.

I think that longer-term, separability has more benefits from a maintenance and

The final result: require() any module on npm in your browser console with browserify

This article is written to explain how the above gif works in the chrome (and other) browser consoles. A quick disclaimer: this whole thing is a huge hack, it shouldn't be used for anything seriously, and there are probably much better ways of accomplishing the same.

Update: There are much better ways of accomplishing the same, and the script has been updated to use a much simpler method pulling directly from browserify-cdn. See this thread for details: https://github.com/mathisonian/requirify/issues/5
