# rpc-bitcoin [](https://travis-ci.com/vansergen/rpc-bitcoin) [](https://snyk.io/test/github/vansergen/rpc-bitcoin)   
A [TypeScript](https://www.typescriptlang.org) library to make RPC and HTTP REST requests to [Bitcoin Core](https://bitcoin.org/en/bitcoin-core/).
## Installation
```bash
npm install rpc-bitcoin
```
## [RPC](https://bitcoin.org/en/developer-reference#remote-procedure-calls-rpcs)
```javascript
const { RPCClient } = require("rpc-bitcoin");
const url = "http://192.168.0.10";
const user = "rpcuser";
const pass = "rpcpassword";
const port = 18832;
const timeout = 10000;
const client = new RPCClient({ url, port, timeout, user, pass });
```
- batch
```javascript
const response = await client.batch([
{ method: "getbestblockhash", id: 1 },
{ method: "help", params: { command: "help" }, id: "custom-id" },
{ method: "getzmqnotifications", params: {}, id: 2 },
