Ideally, it should be able to request a new access token via user input when previously unauthorized scopes are requested.
As a starting point, StaticAuthProvider takes an access token,
but can't do anything to upgrade it by itself. RefreshableAuthProvider
is used as a wrapper around another AuthProvider and can make use of
refresh tokens.
The type of token an auth provider can return - user tokens and app tokens are supported.
Aliased type: "user" | "app"
Properties
getAccessToken
Type: (scopes: string | Array<string>) => Promise<AccessToken | null>
Retrieves an access token from the provider.
This should automatically request a new token when the current token is not authorized to use the requested scope(s).
When implementing this, you should not do anything major when no scopes are requested - the cached token should be valid for that - unless you know exactly what you're doing.
refresh
Type: ?() => Promise<AccessToken | null>
Requests that the provider fetches a new token from Twitch.
This method is optional to implement. For some use cases, it might not be desirable to e.g. ask the user to log in again at just any time.
tokenType
Type: AuthProviderTokenTypeThe type of token an auth provider can return - user tokens and app tokens are supported.
Aliased type: "user" | "app"
The type of token an auth provider can return - user tokens and app tokens are supported.
Aliased type: "user" | "app"
The type of the tokens generated by the provider, i.e. whether this is a user or app token.
If you don't give this information, it's assumed that the provider generates user tokens.
