import { WsProvider } from '@polkadot/rpc-provider';

communityId = '3LjCHdiNbNLKEtwGtBf6qHGZnfKFyjLu9v3uxVgDL35C';

/// In async function
// connect to Encointer node
const api = await ApiPromise.create({
    ...options({
        /// additional types
    }),
    provider: new WsProvider(nodeAddr)
});

// Get first worker endpoint from registry
const workerEndpoint = await api.query.substrateeRegistry.enclaveRegistry(1)

// Create worker
const worker = new EncointerWorker(workerEndpoint, { api });

// Get public data from worker
const total = await worker.getTotalIssuance(communityId);

console.log('Total issuance:', total);

const bob = keyring.addFromUri('//Bob', { name: 'Bob default' });

// Query balance from worker
const balance = worker.getBalance(bob, communityId);

console.log('Bob owns:', balance);

Publish to npm

// will prompt you to select version to increase, e.g. major, minor, patch etc. (Creates git tag!)
lerna version --force-publish

// apply changes from package.json to */build/package.json 
yarn build

// publish all changes from the build directory to npm
lerna publish from-package --contents build

The lerna commands have been added as scripts to the package.json.

WARN When the packages are linked in the js_encointer_service and yarn install is run, it will create a node_modules folder inside the build folder. Do NOT publish this one. However, with the above sequence, this will be fine, as yarn build cleans the build directory first.
