# 🌤 Aircall Weather

An **Aircall Creative Lab** app, sending weather information to Aircall users during calls.

It is written in [**NodeJS**](https://nodejs.org/en/) (v12.0.0),
stores data in a [**DynamoDB**](https://aws.amazon.com/dynamodb/) database,
and runs in a [**Docker**](https://www.docker.com/) container.

## Development

### 📝 ENV variables

Make sure all ENV variables are defined in your `.env` file.
A template is available:

```bash
cp .env_template .env
```

You will need:

- OAuth credentials `AIRCALL_OAUTH_ID` and `AIRCALL_OAUTH_SECRET`. Please reach out to marketplace@aircall.io and we'll give you some!
- `OPEN_WEATHER_API_KEY`: get your free API key [here](https://openweathermap.org/price).

### 🐳 Install docker

This app is Docker compatible, both for local development and production environment.
Install the latest version of Docker CE for your OS:

- [macOS](https://docs.docker.com/docker-for-mac/install/)
- [Windows](https://docs.docker.com/docker-for-windows/install/)
- [Linux Ubuntu](https://docs.docker.com/install/linux/docker-ce/ubuntu/)

To have the full setup of Maestro with all the dependencies, use `docker-compose`.
Docker provides instructions [here](https://docs.docker.com/compose/install/).

### ⚙️ DynamoDB

This project requires you to have [DynamoDB](https://aws.amazon.com/dynamodb/) installed locally.
AWS provides instructions [here](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/DynamoDBLocal.html).

Once you downloaded this Docker's image [dynamodb-local](https://hub.docker.com/r/amazon/dynamodb-local)
and you launched it, you will need to locally create the `Company` table:

```bash
node -r dotenv/config scripts/createDBTables.js
```

### 🚀 Run the app

```bash
docker-compose up --build
```

## Test

We use [Jest](https://jestjs.io/) as a testing framework. Launch the following command to run tests:

```bash
npm test
```

## Production

Aircall uses Docker in Production.

First, you'll have to build the Docker image:

```bash
docker build -t aircall-weather .
```

Once done, you can then run it with the following command:

```bash
docker run -p 5000:5000 -d aircall-weather
```

In production, the `DEBUG` environment variable must be set to `false`.

## MISC

### Phone number to region matching
