ReactTracer Shared Transform For React 19

Package: @autotracer/inject-react19  ·  Layer: Build  ·  Type: Overview

---

Use this page for the low-level build-time transform shared by the React 19 Vite and Babel plugins.

This package owns the shared AST transform, the shared transform configuration, and helper APIs for tool authors. It does not initialize reactTracer(), it does not expose globalThis.autoTracer, and it does not load theme files.

Normal Integration

Use @autotracer/plugin-vite-react19 or @autotracer/plugin-babel-react19 for normal app integrations.

Use @autotracer/inject-react19 directly only when you are authoring custom build tooling and you need direct control over transform() and normalizeConfig().

Settings By Concern

• Eligibility and precedence: mode, include, and exclude
• Framework and import wiring: serverComponents and importSource
• Hook labeling: labelHooks and labelHooksPattern

Adjacent Context Surface

Custom tooling can pass prefix through TransformContext when multiple islands, micro-frontends, or other independent React entry points share one browser tab and you need injected component names to stay distinguishable as prefix:ComponentName.

Use @autotracer/inject-react19 for the exact TransformContext shape.
