Web Tracing Framework

Build Status

The Web Tracing Framework is a set of libraries, tools, and visualizers for the tracing and investigation of complex web applications. You spend a small amount of time instrumenting your code and it helps you discover performance problems, track regressions, and build buttery-smooth 60fps web apps.

This is still very much a work in progress, and not designed to work for all applications. If you find issues when using it with your application please contribute fixes!

For documentation, tutorials, etc see the main Web Tracing Framework website.

For a list of known issues see KNOWN_ISSUES or the Github issues list.

Setup

See building for instructions and testing for information on running the various tests.

Quickstart

Just want the extension as fast as possible?

umask 0022
git clone https://github.com/google/tracing-framework.git
cd tracing-framework/
./scripts/setup.sh # or setup.bat on Windows
source wtfrc && deployext
# At chrome://extensions load unpacked extension from
# build-bin/wtf-injector-chrome

If you pull new changes, just redeploy:

git pull && git submodule update
deployext
# Reload from chrome://extensions

For more information and other build options, see building.
