ios-har-builder

Loads pages in iOS Safari and builds a HTTP Archive (HAR) file for page load.

This is work-in-progress and liable to change

Install

1. Clone repository
2. Run npm install to install dependencies
3. Install Google's proxy that connects Chrome DevTools to iOS WebKit - https://github.com/google/ios-webkit-debug-proxy (there's a homebrew recipe for this)

Usage

Start the proxy:

$ ios_webkit_debug_proxy

Then either launch the iOS Simulator or connect an iPhone/iPad via USB cable and launch Safari

Usage: bin/ios-har-builder [options] URL...

options:
  --output, -o   Dump generated HAR to file instead of stdout
  --verbose, -v  Enable verbose output

N.B. Options for host and port don't currently work

Example:    bin/ios-har-builder -o example.har http://m.guardian.co.uk

Credits

ios-har-builder is based on a fork of chrome-har-capturer (https://github.com/cyrus-and/chrome-har-capturer) by Andrea Cardaci (cyrus.and@gmail.com)

It's a separate fork for now as there are some differences in behaviour between Chrome and Safari e.g. lack of navigation / resource timing in Safari, Safari wraps the WebKit debug protocol in RPC etc.

Issues

• Cookies aren't currently supported
• Code needs cleaning up and refactoring in several places
• Host and Port parameters don't work

Resources

• HAR 1.2 Spec
• HAR Viewer
• Chrome Developer Tools: Remote Debugging Protocol v1.0
