Mobicoop V3 - Ad

Ad service for Mobicoop V3.

Requirements

You need Docker and its compose plugin.

You also need NodeJS installed locally : we strongly advise to install Node Version Manager 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 :

  cp .env.dist .env
  

  Modify it if needed.

• install the dependencies :

  npm install
  

• start the containers :

  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) :

npm run migrate

Usage

The app exposes the following gRPC services :

• FindById : find an ad by its id

  {
      "id": "80126a61-d128-4f96-afdb-92e33c75a3e1"
  }
  

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

  Punctual driver ad :

  The list of possible options when creating an ad :

  • id (optional): the id of the ad (as a uuid)

  • userId: the user id (as a 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

  • fromDate: start date for recurrent ad, carpool date for punctual ad

  • toDate: end date for recurrent ad, same as fromDate for punctual ad

  • schedule: an object with the departure time for each carpooled day in the week (only the carpooled day for punctual ad)

  • marginDurations (optional): an object with the margin duration (in seconds) for each carpooled day in the week, eg:

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

  • seatsProposed (optional): number of seats proposed as driver

  • seatsRequested (optional): number of seats requested as passenger

  • strict (boolean, optional): if set to true, allow matching only with similar frequency ads

  • waypoints: an array of addresses that represent the waypoints of the journey (only first and last waypoints are used for passenger ads). Note that positions are required and must be consecutives

  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).

# 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
