(🚧 WIP) Session Recorder

Imagine that a video camera continuously record the whole page

See also Session-Player for consuming Recorder's data

Record list:

• DOM mutation
• Network(xhr, fetch, beacon)
• Global Error, Unhandled rejection
• Mouse, Scroll
• Console

Output like:

[
  {"t": 0, "type": "snapshot", "snapshot": "#document snapshot", "scroll": ... },
  { "t": 1, "type": "node", "add": [{ "html": "<div id>textContent</div>" }], "target": 6 },
  { "t": 2, "type": "form", "target": 16, "k": "value", "v": "2312" },
  { "t": 3, "type": "attr", "target": 14, "attr": { "k": "class", "v": "a" } },
  { "t": 4, "type": "scroll", "x": 0, "y": 10 },
  { "t": 5, "type": "click", "x": 71, "y": 13 },
  { "t": 6, "type": "form", "target": 19, "k": "checked", "v": true },
  { "t": 7, "type": "jserr", "msg": "Type Error: ...", "url": "...", "err": "..." },
  { "t": 8, "type": "xhr", "url": "...", "method": "GET", "response": "21asdcxz" },
  { "t": 9, "type": "fetch", "status": 503, "response": "21asdcxz" },
  { "t": 10, "type": "move", "x": 38, "y": 510 },
  { "t": 11, "type": "console", "l": "warn", "msg": "..." }
]

Code intergration:

npm i session-recorder

import SessionRecorder from 'session-recorder'

const myReocrder = new SessionRecorder()

myReocrder.start() // make sure start after DOMContentLoaded
myReocrder.end() // stop record

TODO

• Use VDOM record mutation
• Using WebWorker store trail data

# serve file with hot reload at http://localhost:8000
