outputMode

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

---

outputMode is a build configuration option passed to @autotracer/plugin-babel-flow in your Babel config. It injects startup statements into processed modules that import @autotracer/flow or @autotracer/flow/runtime so the desired AutoTracer output mode can be established before traces run.

When set, the injected startup block seeds globalThis.__autoTracerInternal.outputMode if the shared internal state does not exist yet, and calls globalThis.autoTracer.setOutputMode(...) when the public runtime API is already installed.

Use @autotracer/flow when you need to change output mode later at runtime.

Default

If you omit outputMode, the Babel plugin does not inject startup output-mode statements.

Values

• "devtools": interactive console grouping through the browser's native grouping behavior.
• "copy-paste": text output shaped for copying into bug reports, chat, or documents.
