outputMode

Package: @autotracer/plugin-babel-react18  ·  Layer: Build  ·  Type: "devtools" | "copy-paste"  ·  Default: undefined

---

outputMode is a build configuration option passed to @autotracer/plugin-babel-react18 in your Babel config. It injects a seed-only startup block into processed modules so the canonical AutoTracer output mode can be established before the first trace runs.

When set, the Babel plugin inserts statements after any directive prologue in transformed modules. If globalThis.__autoTracerInternal is still undefined, the injected code seeds its outputMode field and, when the runtime surface already exists, calls globalThis.autoTracer.setOutputMode(...). If the internal state already exists, the injected bootstrap does nothing.

This setting does not replace runtime initialization with reactTracer(). Use ReactTracer Runtime outputMode for the exact runtime meaning of "devtools" and "copy-paste".
