prefix

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

---

prefix is a build configuration option for flowTracer() — the Vite plugin initializer of the @autotracer/plugin-vite-flow Flow build-time instrumentation package. 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 and exclude are applied before the transform builds the final emitted name. Runtime start and stop behavior is also unchanged.

Use this when multiple independent bundles 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.

Usage

flowTracer({
  prefix: "Storefront",
});
