Use Auth Client

@dfinity/use-auth-client

@dfinity/use-auth-client! This is a package for Internet Computer React developers, making it easier to integrate the auth-client with your React application.

You can use it to manage your identity for you, or you can pass it an idlFactory and canisterId and it will construct and manage your entire Actor for you.

Installation

To install, use:

npm install @dfinity/use-auth-client

and you can import and set it up like so:

import {useAuthClient} from '@dfinity/use-auth-client';

...ts
const App = () => {
  const identityProvider =
    // eslint-disable-next-line no-undef
    process.env.DFX_NETWORK === 'local'
      ? // eslint-disable-next-line no-undef
        `http://${process.env.CANISTER_ID_INTERNET_IDENTITY}.localhost:4943`
      : 'https://identity.internetcomputer.org';

  const { isAuthenticated, login, logout, actor } = useAuthClient({
    loginOptions: {
      identityProvider,
    },
    actorOptions: {
      canisterId,
      idlFactory,
    },
  });
  ...
}

Multiple Actors

If you have multiple actors, you can pass a record of actorOptions to the useAuthClient hook. The keys of the record will be the names of the actors, and the values will be the actorOptions for that actor. It will look something like this:

const { isAuthenticated, login, logout, actors } = useAuthClient({
  actors: {
    actor1: {
      canisterId: canisterId1,
      idlFactory: idlFactory1,
    },
    actor2: {
      canisterId: canisterId2,
      idlFactory: idlFactory2,
    },
  },
});

const { actor1, actor2 } = actors;
