Joystream API Examples
Repo with examples on how to use the @joystream/types package along with @polkadot/api to communicate with a joystream full node.
Examples
yarn && yarn build
yarn run status
Example code
import { registerJoystreamTypes } from '@joystream/types';
import { ApiPromise, WsProvider } from '@polkadot/api';
async function main () {
// Initialise the provider to connect to the local node
const provider = new WsProvider('ws://127.0.0.1:9944');
// Register types before creating the API
registerJoystreamTypes();
// Create the API and wait until ready
const api = await ApiPromise.create({ provider });
// Retrieve the chain & node information information via rpc calls
const [chain, nodeName, nodeVersion] = await Promise.all([
api.rpc.system.chain(),
api.rpc.system.name(),
api.rpc.system.version()
]);
console.log(`Chain ${chain} using ${nodeName} v${nodeVersion}`);
}
main();
