ParamName

Extract the Name type variable from a Param type.

This utility type may be useful for implementing custom parameters whose type is in some way based on the type of another parameter. Currently, it's provided mostly as a counterpart to ParamArg, although unfortunately there are no real-world examples of it in use at the time of writing.

import { Param, ParamName } from "@snout/router-path";

type ParamA = Param<"a">; // a parameter named "a"
type Name = ParamName<ParamA>; // the extracted Name type is "a"

Try me!
