LNRPC

CircleCI Known Vulnerabilities NPM Version License

Maintained fork of lnrpc adding support for generating typescript type definitions.

Features

  • Auto-generates lnd/lnrpc client and typescript definitons based on target release tag
  • Wraps requests in promises
  • Easily setup SSL and Macaroons
  • Instantiates all gRPC services
  • uint64/int64 types cast to string

Installation

npm install @radar/lnrpc
# OR 
yarn add @radar/lnrpc

Install lnd before using this project and ensure you have an lnd instance running with --no-macaroons, unless you provide macaroon authentication to your lnrpc instance when created.

Change LND gRPC release version

To change the gRPC definitions used for all auto-generated types and RPC methods edit the config.lnd_release_tag value in package.json to the desired LND release tag and run the following:

npm run update-proto
# OR 
yarn update-proto
 
# AND 
 
npm run generate
# OR 
yarn generate

Newly generated type definitions will be available in ./generated.

Usage

Connecting to an lnd instance at localhost:10001.

import createLnRpc, {
  Invoice,
  InvoiceSubscription,
  WalletBalanceResponse
} from '@radar/lnrpc';
 
(async function() {
  const lnRpcClient = await createLnRpc();
 
  // All requests are promisified and typed
  const balanceResponse: WalletBalanceResponse = await lnRpcClient.walletBalance();
 
  // ...and you're off!
  console.log(balanceResponse.confirmedBalance);
 
  // subscribe to LND server events
  const subscriber = await lnRpcClient.subscribeInvoices();
  subscriber.on('data', (invoice: Invoice) => {
    console.log(invoice); // do something with invoice event
  });
})();

Options

    macaroon: process.env.MY_MACAROON_HEX,
  });
 
  try {
    const getInfoResponse: GetInfoResponse = await lnRpcClient.getInfo();
    console.log(getInfoResponse);
  } catch (error) {
    console.error(error);
  }
})();
