Package Exports

devtools-timeline-model
devtools-timeline-model/lib/timeline-model-treeview.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (devtools-timeline-model) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

devtools-timeline-model

Parse raw trace data into the Chrome DevTools' structured profiling data models

If you use something like big-rig or automated-chrome-profiling you may end up with raw trace data. It's pretty raw. This module will parse that stuff into something a bit more consumable, and should help you with higher level analysis.

Install

$ npm install --save devtools-timeline-model

Usage

var filename = 'demo/mdn-fling.json'
var events = require('fs').readFileSync(filename, 'utf8')

var DevtoolsTimelineModel = require('devtools-timeline-model');
// events can be either a string of the trace data or the JSON.parse'd equivalent
var model = new DevtoolsTimelineModel(events)

// tracing model
model.tracingModel()
// timeline model, all events
model.timelineModel()
// interaction model, incl scroll, click, animations
model.interactionModel()
// frame model, incl frame durations
model.frameModel()
// filmstrip model, incl screenshots
model.filmStripModel()

// topdown tree
model.topDown()
// bottom up tree
model.bottomUp()
// bottom up tree, grouped by URL
model.bottomUpGroupBy('URL') // accepts: None Category Subdomain Domain URL

These objects are huge. You'll want to explore them in a UI like devtool.
