Api-Gateway

A lightweight and cost-efficient ready-to-deploy API Gateway. It centralizes client requests, routes them to internal services, logs traffic, and provides an admin UI for monitoring.

👉 Full docs, examples, screenshots and all you need to know, are available in the official GitHub Repo.

Deploy and Host Api-Gateway on Railway

An API Gateway acts as a single entry point for all client requests, routing them to the appropriate internal services. Instead of clients communicating directly with multiple microservices, they only interact with the gateway, which handles:

• 🔀 Request routing → Determines which service should handle the request based on the path.
• 📜 Centralized logging → Captures HTTP logs for monitoring and debugging.
• 🔒 Service abstraction → Clients don’t need to know the internal URLs of services. Services may not be public on the internet.
• 📈 Scalability → Easily connect more services.
• 🖥️ Admin Dashboard → Visual manage routes and review HTTP logs.

About Hosting Api-Gateway

Hosting the Api-Gateway on Railway provisions a complete setup out-of-the-box. The deployment includes:

1. A PostgreSQL database to persist routes, configurations, and logs.
2. A web admin client to manage routes, logs and settings visually.
3. The core gateway service, which processes requests, applies configurations, and handles logging.

This setup isolates your internal microservices from the public internet while providing a single unified API endpoint.

📌 By default, the system uses around 200–250 MB RAM, making it lightweight and cost-efficient.

Common Use Cases

• Unified API Endpoint → Expose a single public URL while routing internally to multiple microservices.
• Improved Security → Keep microservices private and expose only the gateway to the internet.
• Logging & Monitoring → Store traffic logs for auditing.

📌 Future Roadmap include → Analytics, metrics and statistics, and advanced configuration options.

Dependencies for Api-Gateway

Core Dependencies:

• PostgreSQL → Primary database for storing routes, logs, and configurations.

Deployment Dependencies

• Railway PostgreSQL Template: https://railway.com/template/postgres
• Api-Gateway Core Service: https://github.com/Root-101/api-gateway
• Api-Gateway Web Client: api-gateway/tools/api_gateway_front

Implementation Details (Optional)

• Default admin credentials:

  • Username: admin
  • Password: admin123**

⚠️ Update ADMIN_USERNAME and ADMIN_PASSWORD environment variables in Railway before production use.

• The Core Service and the DB are connected through private networking, so the project must have private networking enabled in order for it to work correctly.
• The Web Client is connected to the api gateway through RAILWAY_PUBLIC_DOMAIN, pointing to the admin path defined in the env ADMIN_PATH of the gateway service.

Why Deploy Api-Gateway on Railway?

Railway is a singular platform to deploy your infrastructure stack. Railway will host your infrastructure, so you don't have to deal with configuration, while allowing you to vertically scale it.

By deploying Api-Gateway on Railway via this template, you are one step closer to supporting a complete full-stack application with minimal burden, you get a powerful, lightweight, fully configured ready to use, super magic with sprinkles, and reliable api gateway, that would take you multi services architecture to the next level.

This is after all a project designed for deploy in railway as a template... so:
