UAuth JS Library

The @uauth/js library is the core UAuth library for single-page applications. It manages login sessions with the Uauth Service and provides a login popup flow built with React.

Client

The Client class is the default export for the @uauth/js package.

constructor

Copy

Copied

constructor(options: ClientOptions)

const uauth = new Client(options);

login()

Initiates UAuth authentication with an auth server redirect and callback flow. When using this method, the redirectUri in the ClientOptions must point to a page that calls loginCallback().

Copy

Copied

async login(
    options: Partial<LoginOptions> = {}
): Promise<void>

loginWithPopUp()

Initiates UAuth authentication with a React popup flow.

Copy

Copied

async loginWithPopup(
    options: Partial<Omit<LoginOptions, 'responseMode'>> = {},
    config?: PopupConfig,
): Promise<Authorization>

loginCallback()

Parses the authorization code and application state after login() has been called and the authorization server has redirected back to the redirectUri defined in the ClientOptions.

Copy

Copied

async loginCallback<T>(
    options?: Partial<LoginCallbackOptions>,
): Promise<LoginCallbackResponse<T>>

authorization()

Returns the Authorization for the current login session.

Copy

Copied

async authorization(
    options: AuthorizationOptions = {},
): Promise<Authorization>

user()

Returns the UserInfo associated with the current UAuth instance.

Copy

Copied

async user(options: UserOptions = {}): Promise<UserInfo>

getVerifiedAccounts()

Returns VerifiedAddress array containing all verified accounts associated with an authorized domain, with optional symbol filtering, which allows a DApp to request only the verified accounts they are interested in.

Copy

Copied

getVerifiedAccounts(
  authorization: Authorization,
  symbols: string[] = []
): VerifiedAddress[]

getAuthorizationAccount

The UAuth service allows users to login with certain verified accounts associated with a domain's ud.me profile in addition to the Ethereum or Polygon wallet that owns the domain. This method takes an Authorization from loginWithPopup() or loginCallback() and returns a VerifiedAddress describing the account that authorized a login request, such as a verified Solana wallet.

Copy

Copied

getAuthorizationAccount(
    authorization: Authorization,
    type = 'sig',
    version = 'v1'
): VerifiedAddress | undefined

logout()

Executes the beforeRedirect callback if defined in LogoutOptions, deletes the session authorization from the local clientstore, and redirects to the postLogoutRedirectUri.

Copy

Copied

async logout({
    clientID,
    username,
    scope,
    resource,
    ...options
}: Partial<LogoutOptions> = {}): Promise<void>
