# routeParamNames

**Kind:** Function

**Source:** [`atloria-monorepo/libs/parser-core/src/openapi/path-parameters.ts`](https://github.com/sherkety/atloria/blob/main/atloria-monorepo/libs/parser-core/src/openapi/path-parameters.ts#L56)

The variable segments of a route template, in URL order, deduped and stripped of framework
decoration.

Deliberately dialect-agnostic, because one endpoint list mixes them: NestJS and Express write
`:id`, OpenAPI/Spring/.NET write `{id}`, Laravel writes `{id?}` for optional and Rails
`{id:uuid}` for constrained, and PHP string interpolation leaks `{$endpoint}` out of
`Route::match($verbs, "{$endpoint}{format?}")`. All of them name the same thing: a segment
the caller supplies.

For parsers only. They own the path text as well as the parameter list, so they can normalize
both together; the spec-level backstop below cannot, and matches tokens verbatim instead.
