Installation 🚀

Prerequisites

Make sure you have the following installed:

• Go v1.18+
• Svelte 5
• Docker & Docker Compose
• Redis
• RabbitMQ
• PostgreSQL
• Prometheus
• Grafana

Steps to Install

1. Clone the repository:

   git clone https://github.com/mBuergi86/devseconnect.git
   cd devseconnect

2. Install dependencies:

   go mod download

3. Run with Docker:

   docker-compose up -d --build

4. Run locally (without Docker):

   go run cmd/main.go

5. Log Webserver:

API Endpoints 🔗

The platform uses RESTful APIs to handle different operations:

• Users:

  • GET /users – Fetch all users.
  • POST /users – Create a new user.
  • PUT /users/:id – Update a user with id.
  • DELETE /users/:id – Delete a user with id.

• Posts:

  • GET /posts – Fetch all posts.
  • POST /posts/:username – Create a new post.
  • PUT /posts/:id – Update a post with id.
  • DELETE /posts/:id – Delete a post with id.

• Comments:

  • GET /comments – Fetch all comments.
  • POST /comments/:title/:username – Add a comment to a post.
  • PUT /comments/:id – Update a comment with id.
  • DELETE /comments/:id – Delete a comment with id.

• Likes:

  • GET /likes – Fetch all likes.
  • POST /likes/:title/:username – Like a post.
  • POST /likes/:content/:username – Like a comment.
  • DELETE /likes/:id – Delete a like with id.

Database Schema 🗄️

The database is managed using PostgreSQL, and migration scripts are located in scripts/migrations/. The key tables include:

• users
• posts
• comments
• messages
• likes
• tags
• post_tags

Messaging System ✉️

Asynchronous communication between services is managed via RabbitMQ. Producers and consumers are defined in the internal/infrastructure/messaging/ directory.

Monitoring 📊

Prometheus is used for application monitoring and metrics collection. The configuration is located in prometheus.yml.
