### Set Up BCRPC
Create a new node.js project and install BCRPC via NPM.
``` ```
$ mkdir myproject curl -sL https://deb.nodesource.com/setup_14.x | sudo bash -
$ cd myproject sudo apt-get install -y nodejs
$ npm init sudo npm install mocha -g
[...]
$ npm install --save bcrpc
``` ```
### Test BCRPC ### Test BCRPC
To test the BCRPC package, you must first set environmental variables for your rpcuser and rpcpassword. As noted in [§12.1: Accessing Bitcoind with Curl](12_1_Accessing_Bitcoind_with_Curl.md), these come from `~/.bitcoin/bitcoin.conf`. Clone the BCRPC package from GitHub and install its dependencies.
```
$ git clone https://github.com/dgarage/bcrpc.git
$ cd bcrpc
$ npm install
```

As noted in [§12.1: Accessing Bitcoind with Curl](12_1_Accessing_Bitcoind_with_Curl.md), these come from `~/.bitcoin/bitcoin.conf`. You must also set the RPC port to 18332 which should be correct for the standard testnet setup described in these documents.
``` ```
$ export BITCOIND_USER=bitcoinrpc $ export BITCOIND_USER=bitcoinrpc
$ export BITCOIND_PASS=d8340efbcd34e312044c8431c59c792c $ export BITCOIND_PASS=d8340efbcd34e312044c8431c59c792c
$ export BITCOIND_PORT=18332
``` ```
