Package Exports

devtools-timeline-model

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

const filename = 'demo/mdn-fling.json'

var fs = require('fs')
var events = fs.readFileSync(filename, 'utf8')
const devtoolsTimelineModel = require('devtools-timeline-model');
var model = devtoolsTimelineModel(events)

//=>
model.timelineModel // full event tree
model.irModel // interactions, input, animations
model.frameModel // frames, durations
model.filmStripModel // screenshots
