# Mobicoop V3 - Ad

Ad service for Mobicoop V3.

## Requirements

You need [Docker](https://docs.docker.com/engine/) and its [compose](https://docs.docker.com/compose/) plugin.

You also need NodeJS installed locally : we **strongly** advise to install [Node Version Manager](https://github.com/nvm-sh/nvm) and use the latest LTS version of Node (check that your local version matches with the one used in the Dockerfile).

The API will run inside a docker container, **but** the install itself is made outside the container, because during development we need tools that need to be available locally (eg. ESLint or Prettier with fix-on-save).

A RabbitMQ instance is also required to send / receive messages when data has been inserted/updated/deleted.

## Installation

-   copy `.env.dist` to `.env` :

    ```bash
    cp .env.dist .env
    ```

    Modify it if needed.

-   install the dependencies :

    ```bash
    npm install
    ```

-   start the containers :

    ```bash
    docker compose up -d
    ```

    The app runs automatically on port **5006**.

## Database migration

Before using the app, you need to launch the database migration (it will be launched inside the container) :

```bash
npm run migrate
```

## Usage

The app exposes the following [gRPC](https://grpc.io/) services :

-   **FindByUuid** : find an ad by its uuid

    ```json
    {
        "uuid": "80126a61-d128-4f96-afdb-92e33c75a3e1"
    }
    ```

-   **Create** : create an ad (note that uuid is optional, a uuid will be automatically attributed if it is not provided)

    Punctual driver ad :

    ```json
    {
        "userUuid": "80c9bb02-0931-4a1d-bea6-22d358992245",
        "driver": true,
        "seatsDriver": 3,
        "frequency": "PUNCTUAL",
        "departure": "2023-01-15 09:00",
        "addresses": [
            {

    The list of possible options when creating an ad :

    -   uuid (optional): the uuid of the ad
    -   userUuid: the user uuid
    -   driver (boolean, optional): if the ad is a driver ad
    -   passenger (boolean, optional): if the ad is a passenger ad
    -   frequency: `PUNCTUAL` or `RECURRENT`
    -   departure (required if punctual): departure date and hour/minute for a punctual ad
    -   fromDate (required if recurrent): start date for recurrent ad
    -   toDate (required if recurrent): end date for recurrent ad
    -   schedule (required if recurrent): an object with the departure time for each carpooled day in the week
    -   marginDurations (optional): an object with the margin duration (in seconds) for each carpooled day in the week, eg:

            {
                "mon": 900,
                "tue": 850,
                "fri": 950
            }

    -   seatsDriver (optional): number of seats proposed as driver;
    -   seatsPassenger (optional): number of seats requested as passenger;
    -   strict (boolean, optional): if set to true, allow matching only with similar frequency ads
    -   addresses: an array of adresses that represent the waypoints of the journey (only first and last waypoints are used for passenger ads)

    Default values must be set in `.env` file.

## Messages

As mentionned earlier, RabbitMQ messages are sent after these events :

-   **Create** (message : the created ad informations)

## Tests / ESLint / Prettier

Tests are run outside the container for ease of use (switching between different environments inside containers using prisma is complicated and error prone).
The integration tests use a dedicated database (see _db-test_ section of _docker-compose.yml_).

```bash
# run all tests (unit + integration)
npm run test

# unit tests only
npm run test:unit

# integration tests only
npm run test:integration

# coverage
npm run test:cov

# ESLint
npm run lint

# Prettier
npm run pretty
```
