react-19-plugin-migration
Migrate a Grafana plugin to React 19 compatibility. Use when the user asks to update a plugin for React 19, prepare for React 19, fix React 19 compatibility, upgrade to React 19, migrate to React 19, bump grafanaDependency to 12.3.0, externalize jsx-runtime, or run react-detect. Triggers on phrases like "update plugin for React 19", "React 19 migration", "prepare for React 19", "plugin React 19 compat", "grafanaDependency 12.3.0", "JSX runtime externals", "react-detect", "SECRET_INTERNALS", "ReactCurrentOwner", or "ReactCurrentDispatcher".

Migrate Grafana Plugin to React 19 Grafana 13 (April 2026) moves from React 18 to React 19. Incompatible plugins will break. Do not upgrade React to 19 — only make forward-compatible changes. All changes go in one PR. Execute steps in order. Never manually edit yarn.lock. --- Step 1: Detect plugin context If PLUGINID is empty, ask the user for the plugin root path. --- Step 2: Scan for compatibility issues Build the plugin and run the React 19 compatibility scanner: Save the output. It flags: jsxRuntimeImport / SECRETINTERNALS → Step 4 fixes this defaultProps / propTypes / ReactDOM.render → Step 8 (source fixes) findDOMNode → Step 6 (dependency bump) or Step 8 (source fix) If the build fails (plugin hasn't been built before), skip this step and run react-detect after Step 9 instead. If output says "No breaking changes detected", still proceed — jsx-runtime externalization and grafanaDependency bump are always required.
