GENERAL PROJECT

API Gateway

Planned

Backend Routing and Integration Experiment
Gateway experiment for routing requests, middleware, validation, proxying, and service boundaries.

PLANNED PROJECT

API Gateway

Learn the role of a gateway by routing and coordinating requests instead of building another CRUD service. The implementation is planned.

Purpose & Learning Objectives

Why this project exists and what the implementation should teach.
Purpose / Learning

Purpose

Learn the role of a gateway by routing and coordinating requests instead of building another CRUD service.

Learning Objectives

  • Route incoming requests to defined downstream services.
  • Apply middleware consistently.
  • Validate and normalize request metadata.
  • Handle upstream failures and timeouts.
  • Understand proxy boundaries and service composition.
  • Compare gateway responsibilities with the TypeScript API Service.

Implementation Scope

Planned behaviors, architecture decisions, and evidence this project should produce.
Routing
Map incoming paths to service destinations.
Middleware
Centralize concerns that should not be repeated in every service.
Failure behavior
Make upstream problems visible and controlled.
Comparison
Document what belongs in a gateway versus a domain API.

Project Notes

Implementation context, boundaries, and later expansion.
Project Notes

Framework Decision

Express and Fastify are candidates; the learning objective matters more than framework branding.

Relationship

Use the TypeScript API Service later as one possible downstream service.
