Function keyAs

keyAs<K extends string, P extends Path<string, any>>(
    key: K,
    path: P,
): Path<
    `:${K}${WrapTypeIndicator<ReadableRepresentationOfPath<P>>}`,
    { [key in string]: DataOfPath<P> },
>
Creates a new Path that maps the params of the given path to an object with a single key.

This is useful for assigning a name to a path parameter, so that the matched value is returned as an object with the specified key, rather than as a raw value.

For example, keyAs("id", parseNumber) will produce a Path that matches a number and returns { id: number } as params.
Type Parameters
- K extends string
- P extends Path<string, any>
Parameters
- key: K
  The name to assign to the matched parameter.
- path: P
  The Path whose params will be wrapped under the given key.
Returns Path<
`:${K}${WrapTypeIndicator<ReadableRepresentationOfPath<P>>}`,
{ [key in string]: DataOfPath<P> },
>
A new Path with params as an object keyed by key.
