Mobicoop V3 - Territory Service

Territory data management.

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, Prettier...).

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 5004.

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 :

• FindForPoint : find all territories that include a given point (represented by its longitude and latitude)

  {
      "lon": 5.493345,
      "lat": 46.143376
  }
  

• FindByUuid : find a territory by its uuid

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

• FindAll : find all territories; you can use pagination with page (default:1) and perPage (default:10)

  {
      "page": 1,
      "perPage": 10
  }
  

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

  {
      "name": "Ain",
      "shape": "[[[[ 4.7953935, 46.2200671 ], [ 4.793835, 46.2155098 ], ... [ 4.7967607, 46.2219542 ], [ 4.7953935, 46.2200671 ]]]]"
  }
  

  Note that shape must be a string representation of the coordinates value of a GeoJSON MultiPolygon

• Update : update a territory

  {
      "uuid": "80126a61-d128-4f96-afdb-92e33c75a3e1",
      "name": "Ain",
      "shape": "[[[[ 4.7953935, 46.2200671 ], [ 4.793835, 46.2155098 ], ... [ 4.7967607, 46.2219542 ], [ 4.7953935, 46.2200671 ]]]]"
  }
  

  Note that shape must be a string representation of the coordinates value of a GeoJSON MultiPolygon

• Delete : delete a territory by its uuid

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

Messages

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

• Create (message : the created territory informations, without the shape)

• Update (message : the updated territory informations, without the shape)

• Delete (message : the uuid of the deleted territory)

Various messages are also sent for logging purpose.

Tests

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
