Chrome-HAR

{:.no_toc}

Create HAR files based on Chrome Debugging Protocol data.

Code originally extracted from Browsertime, initial implementation inspired by Chromedriver_har.

Introduction

Chrome-HAR is for tool makers: Get the log from the Chrome Debugging Protocol and use Chrome-HAR to parse it to a HAR.

Example

Convert your messages to a HAR file.

const parser = require('chrome-har');

// you already have the message from Chrome Debugging Protocol

parser.harFromMessages(messages))
 .then(har => {
   // do whatever you want with the HAR file
 })
