prefix

Package: @autotracer/plugin-babel-flow  ·  Layer: Build  ·  Type: string  ·  Default: undefined

---

prefix is a build configuration option passed to @autotracer/plugin-babel-flow in your Babel config. It prepends a fixed segment to every instrumented function name using : as the separator.

If you set prefix: "Storefront", a function that would normally log as processOrder logs as Storefront:processOrder. Nested function names keep the prefix as the first segment.

Filtering still uses the original unprefixed function name, because include, exclude, and pragma selection are applied before the transform builds the final emitted name. Runtime start and stop behavior is also unchanged.

Use this when multiple independent entry points share one browser console and you need their traces to stay visually distinct. Read together with include and exclude.

Default

If you omit prefix, function names are logged without an extra prefix.
