@cto.ai/ops-keycloak

CTO.ai Keycloak library

Straightforward Keycloak integration.

API

This is a native ESM module.

keycloak(opts) => instance

Options:

• realm - the keycloak realm name
• url - the keycloak server URL
• id - client id
• pages - an object that must contain the following properties: signup, signin, error. Each must hold a Buffer instance, containin HTML to redirect a users browser after a user has registered, logged in or if there was an error, respectively.
• backend default: false - backend mode limited API. Only functionality that doesn't rely on client-side browser interactions is supplied: refresh, signout and signin, where signin must be passed user and password. Pages are not required when backend is true.

Tokens objects:

Much of the API either accepts or outputs tokens. A tokens object has the following shape:

{
  accessToken: string
  refreshToken: string
  idToken: string
  sessionState: string
}

instance.signup() => Promise => tokens

Opens the default browser to the registration URL and supplies tokens once the registration process has been completed in the browser.

instance.signin(opts) => Promise => tokens

Triggers a browser-based login flow or logs in with a given username and password.

If both user and password options are supplied these credentials will be exchanged for tokens. Otherwise, opens the default browser to the login URL and supplies tokens when the login process has been completed in the browser.

Options:

• user Optional - username
• password Optional - password

instance.refresh(tokens) => Promise => tokens

Accepts a tokens object and fetches fresh tokens.

instance.signout(tokens) => Promise

Invalidates the tokens passed.

instance.reset(opts)

Will open a browser at a Keycloak password reset URL, which differs based on the signedIn options.

Options:

• signedIn (boolean), Default: false - If true the browser will open to the logged-in accounts password page. If false it will open to reset credentials page.

instance.teams(tokens) => Promise => [teams]

Returns a promise that resolves the teams for the user that the tokens belong to.

instance.validate(tokens) => boolean

See keycloak.validate

instance.identity(tokens) => { id, username, email }

See keycloak.identity

keycloak.validate(tokens) => boolean

Checks whether tokens.refreshToken has expired. If it has validate returns true, otherwise false.

If any tokens are missing from the tokens object, this function will throw.

keycloak.identity(tokens) => { id, username, email }

Decodes tokens.idToken and returns an object with a users id, username and email.

Caveats

This library does not attempt to provide anything close to full Keycloak functionality integration.
