Introduction

This project is a RESTful API built with Go, utilizing only its standard library. It serves as a basic CRUD (Create, Read, Update, Delete) application for managing user data.

Features

• Rate limiting
• Logging using slog
• Data validation
• Error handling

Requirements

• Go 1.21

Installation

1. Clone this repository.

   git clone https://github.com/your-username/api-std-lib.git

2. Install dependencies (postgres driver).

    go get

3. Run the application.

    go run main.go
   

Endpoints

• POST /user : Create a new user
• GET /user : Fetch all users
• GET /user/{id} : Fetch a single user by ID
• PUT /user/{id} : Update a user by ID
• DELETE /user/{id} : Delete a user by ID

Why Go's Standard Library?

The purpose of using Go's standard library for this project is to demonstrate that it's possible to build a highly efficient, fast, and secure RESTful API without relying on third-party libraries or frameworks. This approach leads to lightweight, easy-to-maintain code and allows for greater control over the application's behavior. Key benefits include:

• Simplicity: Reduced code complexity by utilizing native functionalities.
• Performance: Highly optimized, native solutions for common tasks like HTTP routing, data encoding/decoding, and database connection pooling.
• Security: Reduced surface area for security vulnerabilities by relying on well-tested, standard implementations.
• Learning: Great way to understand the inner workings of various components like caching, logging, and rate limiting by implementing them from scratch.
