```bash
yarn config set workspaces-experimental true
```

Then install dependencies

```bash
yarn install
```

### Start

Set the following environment variables:

```bash
export DISPENSER_ADDRESS=0x5409ed021d9299bf6814279a6a1411a7e866a631
export DISPENSER_PRIVATE_KEY=f2f48ee19680706196e2e339e5da3491186e0c4c5030670656b0e0164837257d
export FAUCET_ROLLBAR_ACCESS_KEY={GET_THIS_FROM_ROLLBAR_ACCOUNT_SETTINGS}
export INFURA_API_KEY={GET_THIS_FROM_INFURA}
```

If you want to talk to testrpc, set the following environment variable:

```bash
export FAUCET_ENVIRONMENT=development
```

Infura API Key can be requested here: https://infura.io/signup

Note: The above public/private keys exist when running `testrpc` with the following option `--mnemonic concert load couple harbor equip island argue ramp clarify fence smart topic`.

```bash
yarn dev
```

### Endpoints

`GET /ping`

Returns `pong`

`GET /info`

Returns a JSON payload describing the state of the queues for each network. For example:

```json
{
    "3": {
        "ether": {
            "full": false,
            "size": 4
        },
        "zrx": {
            "full": false,
            "size": 6
        }
    },
    "42": {
        "ether": {
            "full": false,
            "size": 8
        },
        "zrx": {
            "full": false,
            "size": 20
        }
    }
}
```

`GET /ether/:recipient`

Schedules a transaction that sends 0.1 ETH to the `recipient` where `recipient` is a hex encoded Ethereum address prefixed with `0x`.

`GET /zrx/:recipient`

Schedules a transaction that sends 0.1 ZRX to the `recipient` where `recipient` is a hex encoded Ethereum address prefixed with `0x`.

`GET /order/weth/:recipient`

Returns a JSON payload describing an order for 0.1 WETH in exchange for 0.1 ZRX signed by the dispenser address. The taker is specified by `recipient` where `recipient` is a hex encoded Ethereum address prefixed with `0x`.

`GET /order/zrx/:recipient`

Returns a JSON payload describing an order for 0.1 ZRX in exchange for 0.1 WETH signed by the dispenser address. The taker is specified by `recipient` where `recipient` is a hex encoded Ethereum address prefixed with `0x`.

#### Parameters

The endpoints `/ether`, `/zrx`, `/order/weth/`, and `/order/zrx/`  take a query parameter named `networkId` to specify the desired ethereum network

```bash
curl -i http://localhost:3000/ether/0x14e2F1F157E7DD4057D02817436D628A37120FD1\?networkId=3
```

This command will request the local server to initiate a transfer of 0.1 ETH from the dispensing address to `0x14e2F1F157E7DD4057D02817436D628A37120FD1` on the Ropsten testnet.

If no `networkId` is provided via query parameters the faucet will default to network 42 (Kovan)
