ParamMap
interface
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
