DevTools

Enable managed devtools​

{
  "ui": {
    "devtools": {
      "mode": "managed",
      "sourceDir": "ui/devtools",
      "indexFile": "index.html"
    }
  }
}

parallelBuild defaults to true and runs managed popup + devtools builds in parallel during standard builds. Set parallelBuild to false to force sequential managed UI builds.

Usage model​

  • DevTools UI runs in its own extension UI context.
  • Use HexaUIClient to ask background for data/actions.
  • Keep long-lived state in background/content stores, not in devtools surface state.
