Authentication

Below example shows how to use an embedded signer in order to authenticate client. This approach is not recommended in production, a browser extension should be used instead.

import { ValidAccountId } from '@logion/node-api';
import { Keyring } from '@polkadot/api';

const keyring = new Keyring();
const keypair = keyring.addFromUri("0xe5be9a5092b81bca64be81d212e7f2f9eba183bb7a90954f7b76361f6edb5c0a"); // Alice
const accountId = ValidAccountId.polkadot(keypair.address);
const signer = new KeyringSigner(keyring);

// Authenticate Alice
let authenticatedClient = await client.authenticate(
    [ accountId ],
    signer
);

// Select current account (required if several accounts are authenticated)
authenticatedClient = authenticatedClient.withCurrentAccount(accountId);

// Later on, refresh the session (session's TTL is 1 hour)
authenticatedClient = await authenticatedClient.refreshTokens(DateTime.now());
