All versionsAll versions forward

Version 0.12.0

The Lit panel now reaches pages no dev server is watching. Lit Inspector, a Chrome extension attached to every GitHub release, injects it into any site you enable, production builds and strict Content Security Policies included. lit-devtools dev stops showing controls it can’t serve and gains the Chrome Performance tracks switch, and the selected component keeps updating across a reload. Nothing needs action to upgrade.

Added

  • Lit Inspector, a Chrome extension, comes with every GitHub release. Download lit-inspector-<version>.zip from the release and load it unpacked to inspect Lit components on any page, production builds and sites you don’t serve included, with no dev server.

Changed

  • The panel hides what lit-devtools dev can’t do. Open-in-editor links and the snapshot Export button no longer appear as controls that fail, the Settings tab explains why plugin settings are missing, and the timeline notes when render layers stay empty because the page’s Lit is a production build.

Fixed

  • The panel no longer reports the DevTools’ own Lit as a duplicate. Pages loading lit-devtools.js showed “(duplicate copies)” in Settings and a warning in the components view even with a single Lit of their own.
  • The selected component keeps updating after the page reloads. Its details used to freeze on the old page’s values, marked “update pending”, until you selected another row.
  • Chrome Performance tracks and update flashing can be switched on under lit-devtools dev. The Settings tab hid both whenever the page wasn’t served by the Vite plugin.
