get-casts-example.js

const { getSSLHubRpcClient } = require('@farcaster/hub-nodejs');

const getCastsByFid = async (hubRpcEndpoint, fid) => {
  let client = getSSLHubRpcClient(hubRpcEndpoint);

  client.$.waitForReady(Date.now() + 2000, async (e) => {
    if (e) {
      console.error(`Failed to connect to ${hubRpcEndpoint}`);
    } else {
      console.log(`Connected to ${hubRpcEndpoint}`);
      const castsResult = await client.getCastsByFid({ fid: fid });
      console.log(`${castsResult.value?.messages.length} casts for fid ${fid} from ${hubRpcEndpoint}`);
    }
    client.close();
  });
};
