Matrix and Query parameters.

interface ParamMap {
  keys: string[]
  has(name: string): boolean
  get(name: string): string | null
  getAll(name: string): string[]
}

Description

ParamMap makes it easier to work with parameters as they could have either a single value or multiple value. Because this should be known by the user, calling get or getAll returns the correct type (either string or string[]).

The API is inspired by the URLSearchParams interface. see https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams
