domrec-playwright
Uses domrec-core
to record DOM changes inside playwright scripts. Basically, makes it possible to record videos in headless chrome.
Installation
npm install --save domrec-playwright
or yarn add domrec-playwright

const {PlaywrightRecorder} = require('domrec-playwright')
// ...We are skipping the full setup of the playwright browsing session here
const page = await browser.newPage()
// Setup the Dom Recorder
const recorder = new PlaywrightRecorder(page)
await recorder.init()
// do your thing with playwright
await recorder.stopRecording()
await browser.close()
const recordings = recorder.recordings

What to do with the Use the DOMRecPlayer
from https://github.com/Junkern/DOMRec#replaying
Inner Working
We use the recording.js
from domrec-core
to record dom changes. We also have a second script to simplify using the DOMRecorder
.
To inject the two scripts, we use page.addInitScript
. To receive the data of the dom recording, we use page.exposeFunction
.
At the moment, we only start recording after the DOMContentLoaded
event on the website was triggered and we record the whole document.body
.
There are plans to make both settings (when and what to record) customizable.
