Analyze The Performance Of JavaScript-Heavy Apps With Web Tracing Framework

Web Tracing Framework, by Google, is a set of tools and scripts for analyzing the performance of any JavaScript-related code.

It is mostly ideal for JavaScript-heavy apps and may not be necessary for standard web pages where JavaScript is only used for simple interactions.

There is a manual embedding option and a Chrome extension for getting internal browser data and command line tools (or Nodejs support) for processing this data.

Web Tracing Framework

The framework allows us to choose which methods/events to track and visualizes them in a friendly interface.

A “heap tracking” feature helps finding “how the memory is used by every function” to optimize when necessary.

It works on most modern browsers (in Chrome with all the features) and can be extended.
