REST Users Service

This repository contains a demo implementation of a simple Users microservice. It is based on Symfony 5 PHP framework. It uses MySQL for persistence and RabbitMQ as a message bus.

External services

This microservice communicates over HTTPS with (ipapi.co)[https://www.ipapi.co]. This service is used to geolocate the calling IP on user creation. This service has rate limitation.

• User creation
• User update
• Users search

Development environment

The development environment is based on Docker Compose with the following containers:

• php (running PHP 7.4 FPM)
• www (running httpd 2.4)
• rabbit (running RabbitMQ 3.7)
• mysql (running MySQL 5.7)

Run the application

First and foremost you need to spin up the Docker Compose cluster:

docker-compose up -d

After this you will need to install the Composer dependencies and create the database schemas for both dev and test environments by running the following commands:

docker-compose exec -u www-data php composer install
docker-compose exec -u www-data php bin/console doctrine:database:create -e dev
docker-compose exec -u www-data php bin/console doctrine:database:create -e test
docker-compose exec -u www-data php bin/console doctrine:schema:create -e dev
docker-compose exec -u www-data php bin/console doctrine:schema:create -e test

At this point you should be able to reach the application through your browser. You can try to open up the browser at the following URL: http://localhost:8000.

Note: The project directory is mounted inside the php and www containers at the /var/www/html location.

Run the tests

To run the tests simply execute:

docker-compose exec -u www-data php vendor/bin/phpunit

Automatically fix your code

To automatically fix your code using PHP CS Fixer run this command:

docker-compose exec -u www-data php vendor/bin/php-cs-fixer fix --allow-risky=yes

Perform static code analysis

You can use PHPStan to scan your code for issues:

docker-compose exec -u www-data php vendor/bin/phpstan analyse

Configuration parameters

You can customize the configuration parameters of the application by creating a .env.local file in the project root directory. In this file you can override any environment variable used by the application.
