## Setting up Babel and nodemon

### Inital set-up

Set up project:

```bash
    mkdir project
    cd project
    npm init -y
```

Install dev dependencies:

    npm i --save-dev babel-cli babel-preset-latest nodemon

Configure Babel by adding the lines below to `package.json`:

```json
    "babel": {
      "presets": [
        "latest"
      ]
    },
```

### Scripts

Add some convenience scripts to `package.json`:

```json
    "scripts": {
      "babel-node": "babel-node --presets=latest",
      "start": "nodemon --exec npm run babel-node -- ./index.js",
      "build": "babel src -d dist"
    },
```

To start the Node.js REPL:

    npm run babel-node

To start the app in development mode (letting Babel interpret ES6 code):

    npm start

To build the ES5 code in the `build` directory from the ES6 code in the `src` directory:

    npm build
