prefix

Package: @autotracer/plugin-vite-react18  ·  Layer: Build  ·  Type: string  ·  Default: undefined

---

prefix is a build configuration option for reactTracer.vite() — the Vite plugin initializer of the @autotracer/plugin-vite-react18 React build-time injection package. It prepends a stable label to every injected component name in the trace output.

The plugin formats prefixed names as prefix:ComponentName. Use this when multiple React entry points share one browser tab and you need the trace output to show which island, microfrontend, or app shell produced a render.

This is a build-time label only. Component eligibility is still calculated from the original unprefixed component name before the prefix is applied.

Read together with include and exclude when you are narrowing the eligible set in multi-entry builds.

Usage

reactTracer.vite({
  prefix: "Checkout",
});
