This package defines a TypeScript type `URIParams` which represents the parameters of a URI template defined according to [RFC6570](https://datatracker.ietf.org/doc/html/rfc6570).
npm install uri-template-param-typesThis package defines a TypeScript type URIParams which represents the parameters of a URI template defined according to RFC6570.
Requires TypeScript 4.1 or higher.
``typescript
type APIParameters = URIParams<'/api/my-route/{/path*}{?foo}'>
// Equivalent to:
type APIParameters = {
path?: Array
foo?: string | number | Array
}
`
Using URIParams while working with the url-template library.
`typescript
import urlTemplate from 'url-template'
import { URIParams } from 'rfc6570-param-types'
const template = 'http://example.com/my-route/{id}/whatever{?foo,bar*}'
// TypeScript will check the object against the parameters in the template
const params: URIParams
id: 5,
foo: 'somevalue',
bar: [1, 2, 3],
}
const uri = urlTemplate.parse(template).expand(params)
`
By default, the basic type for a single value is string | number, as described by the RFC6570 standard. However some implementations also handle boolean and null values. For these cases there is an alternative type, PermissiveURIParams.
Example:
`typescript
type APIParameters = PermissiveURIParams<'/api/my-route{?foo}'>
// Equivalent to:
type APIParameters = {
foo?: string | number | boolean | null | Array
}
