@odczynflnpm/totam-illum-necessitatibus
Parse, build and deal with HTTP authorization headers.
This library provide several utilities to parse and build WWW-Authenticate and Authorization headers as described per the HTTP RFC.
It is intended to be framework agnostic and could be used either on the server and the client side. It is also pure functions only, no side effect here. The functions are synchronous since only parsing headers of small size so no need for streams or anything asynchronous.
The module is easily extensible with new mechanisms, one very common way to
extend it is to create a FAKE_TOKEN
mechanism for development only that allows
to directly provide the userId that should be authenticated. You can find
an sample implementation
in the Whook's framework repository.

@odczynflnpm/totam-illum-necessitatibus.parseWWWAuthenticateHeader(header, [authMechanisms], [options]) ⇒ Object
Parse HTTP WWW-Authenticate header contents.
Kind: static method of @odczynflnpm/totam-illum-necessitatibus

Example
assert.deepEqual(
parseWWWAuthenticateHeader('Basic realm="test"'), {
type: 'Basic',
data: {
realm: 'test'
}
}
);
