Note:

When this guide is more complete, the plan is to move it into Prepack documentation.
For now I put it out as a gist to gather initial feedback.

A Gentle Introduction to Prepack (Part 1)

If you're building JavaScript apps, you might already be familiar with some tools that compile JavaScript code to equivalent JavaScript code:

  • Babel lets you use newer JavaScript language features, and outputs equivalent code that targets older JavaScript engines.
View string.md

Strings

String.prototype.*

None of the string methods modify this – they always return fresh strings.

  • charAt(pos: number): string ES1

    Returns the character at index pos, as a string (JavaScript does not have a datatype for characters). str[i] is equivalent to str.charAt(i) and more concise (caveat: may not work on old engines).

What forces layout/reflow. The comprehensive list.

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics
  • elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

from streams session

  • end-of-stream - specify a callback to be called when a stream ends (which is surpsingly hard to get right)
  • duplexify - compose a Duplex stream from a Readable and a Writable stream
  • pump - pipe streams together and close all of them if one of them closes
  • pumpify - combine an array of streams into a single duplex stream using pump and duplexify
  • through2 - tools for making Transform streams
  • from2 - tools for making Readable streams

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

Possible solutions

View generators-vs-fibers.md

Generators vs Fibers

Both ES6 generators and node-fibers can be used to block a coroutine while waiting on some I/O without blocking the entire process. Both can do this for arbitrarily deep call stacks. The main difference between the capabilities of the two is how explicit the syntax is.

Generators - Safe, but Explicit

In code that uses ES6 generators:

var run = require('gen-run'); // https://github.com/creationix/gen-run
