Fastify Todo API

A one-file todo API with Fastify and PostgreSQL. Has basic stuff like rate limiting, CORS, and handles shutdowns properly. Nothing fancy - it just works.

P.S. Yes, it's all in one file. No, we're not sorry.

API Endpoints

• GET /health - Health check endpoint
• GET /todos - Retrieve all todos
• POST /todos - Create a new todo
• PUT /todos/:id - Update an existing todo
• DELETE /todos/:id - Delete a todo

Prerequisites

• Node.js (v20 or higher)
• PostgreSQL database
• npm or yarn

Environment Variables

Create a .env file in the root directory with the following variables:

NODE_ENV=development
PORT=3000
PGUSER=your_db_user
PGHOST=your_db_host
PGDATABASE=your_db_name
PGPASSWORD=your_db_password
PGPORT=5432
CLIENT_URL=http://localhost:3000

Installation

# Install dependencies
npm install

# Start the server
npm start

Database Schema

Ensure your PostgreSQL database has the following table:

CREATE TABLE todos (
  id SERIAL PRIMARY KEY,
  title TEXT NOT NULL,
  completed BOOLEAN DEFAULT FALSE
);

Production Considerations

• Rate limiting is automatically enabled in production
• SSL is enforced for database connections
• CORS is restricted to the specified CLIENT_URL
• Logging is set to 'info' level with minimal request details
