Overview

REST API is a backend-focused Rust project for practicing service structure, endpoint design, and API fundamentals.

The project is useful as a backend portfolio piece because it shows work beyond UI: request handling, route organization, service boundaries, and thinking about predictable API behavior.

---

Problem

Backend projects need more than working endpoints. A useful API should be organized, predictable, and easy to extend without turning every route into isolated logic.

• Routes need consistent naming and behavior
• Business logic should not be tightly coupled to request handlers
• Error handling should be understandable
• The structure should support future persistence or authentication

---

Solution

The project uses Rust to explore a backend service shape where routes, handlers, and service logic can be reasoned about separately.

The scope is intentionally focused on API fundamentals so the repository stays useful for learning and future extension.

---

Architecture

API Layer

• REST-style endpoints
• Request and response flow
• Route organization around resource behavior

Service Layer

• Backend logic separated from route definitions
• Structure prepared for future data storage
• Clear project boundaries for maintainability

Runtime

• Rust-based implementation
• Backend-first structure
• Performance-oriented language choice

Key Features

REST Endpoints

Explores route structure and request/response design for backend services.

Backend Architecture

Practices separating API concerns so the codebase can grow beyond a single-file demo.

Rust Implementation

Uses Rust to strengthen understanding of type safety, ownership, and backend performance fundamentals.

API Fundamentals

Focuses on predictable behavior, maintainability, and clean service boundaries.

---

Challenges

Service Structure

The main challenge was keeping routes and logic organized as the API grew.

Rust Learning Curve

Rust requires more deliberate thinking about data ownership and error handling than many scripting-based backend stacks.

Practical Scope

The project needed to stay focused on API fundamentals without growing into a full production backend too early.

Lessons Learned

• Structuring backend services around clear boundaries
• Thinking about API behavior before UI
• Applying Rust concepts to service development
• Planning for persistence and authentication without overbuilding

---

Future Improvements

• Add database persistence
• Add authentication middleware
• Add request validation
• Add automated API tests
• Add OpenAPI documentation
