Install an old version with homebrew for macOS
  1. Find the formula for the version you want to install:

    • Visit https://github.com/Homebrew/homebrew-core/tree/master/Formula
    • Click the file with your formula (e.g. “composer.rb”)
    • Click “History” (top right)
    • Click the commit hash for the version you want to download
    • Click the three dots (top right of diff) and choose “view file”
    • Click “Raw” and copy the raw URL from the browser address bar.

    For example, composer 1.10.15 lives here: https://github.com/Homebrew/homebrew-core/blob/9e6e6a1ca8551901bff69d329c7fbb9007064134/Formula/composer.rb

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.

Cross origin local storage sharing example (using an iframe and postMessage)
const CrossOriginLocalStorage = function(currentWindow, iframe, allowedOrigins, onMessage) {
this.allowedOrigins = allowedOrigins;
let childWindow;
// some browser (don't remember which one) throw exception when you try to access
// contentWindow for the first time, it works when you do that second time

childWindow = iframe.contentWindow;
} catch(e) {
childWindow = iframe.contentWindow;
