Сервис для добавления и чтения постов и комментариев с использованием GraphQL и PostgreSQL
- Создание постов и комментариев под ними
- Ответы на комментарии
- Просмотр списка постов или отдельного поста
- Просмотр комментариев под постом или другим комментарием
- Включение/выключение комментариев под постом (в т.ч. под существующим)
- Асинхронная доставка комментариев подписчикам поста через GraphQL Subscriptions
- Система пагинации при просмотре списка постов или комментариев
- Язык: Golang 1.25.3
- API: GraphQL
- Контейнеризация: Docker
- Веб-сервер: net/http
- Моки: mock/gomock (uber)
- GraphQL фреймворк: gqlgen
- Хранилище: PostgreSQL / In-memory maps
- Установите Docker на вашу систему соответствующим образом
- Перейдите в директорию, куда хотите сохранить сервис или создайте новую:
mkdir <YOUR-DIRECTORY-NAME> && cd <YOUR-DIRECTORY-NAME>
- Клонируйте репозиторий проекта внутри директории и перейдите в него:
git clone https://github.com/xvnvdu/threads-service.git && cd threads-service
- Соберите образы базы данных и сервиса:
docker compose build
- Запустите контейнер с базой данных в фоновом режиме:
docker compose up -d db
Эта команда запустит PostgreSQL на порту 5432
- После этого запустите сам сервис следующей командой:
docker compose run -p 8080:8080 backend -storage=<CHOOSE-OPTION>
Вы можете выбрать одну из двух опций хранения данных: inmemory или postgres
Флаг -storage опционален. По умолчанию используется postgres
- Вы можете запустить тесты следующим образом:
go test -coverprofile=coverage.out ./internal/repository/inmemory/ -v
- А также проверить покрытие в сгенерированном html файле:
go tool cover -html=coverage.out
Результаты тестирования in-memory хранилища
go test -coverprofile=coverage.out ./internal/repository/inmemory/ -v

- Перед тем как запустить тесты для бд, пожалуйста, создайте тестовую базу данных, используя команду ниже:
docker compose exec db psql -U threads_user -d threads_db -c "CREATE DATABASE threads_test_db;"
- Также необходимо инициализировать таблицы в бд, для этого используйте следующую команду:
docker compose exec db psql -U threads_user -d threads_test_db -f /docker-entrypoint-initdb.d/init.sql
- После чего вы можете запустить тесты следующим образом:
go test -coverprofile=coverage.out ./internal/repository/postgres/ -v
- А также снова проверить покрытие в сгенерированном html файле:
go tool cover -html=coverage.out
