Why JSON REST API?

🚀 Zero Configuration

Get a fully functional API running in under 5 minutes. No complex setup or configuration files needed.

🔌 Plugin Architecture

Extend your API with powerful plugins. Authentication, validation, CORS, and more - just plug and play.

🔗 Smart Relationships

Define relationships once and get automatic joins, nested queries, and eager loading out of the box.

✅ Built-in Validation

Schema-based validation ensures your data is always clean. No more manual validation code.

📦 Multiple Storage Options

Start with in-memory storage for development, switch to MySQL for production. Same API, no code changes.

🎯 JSON:API Compliant

Follow industry standards with native JSON:API support. Compatible with any JSON:API client library.

🌐 Microservices Ready

Build distributed systems with native microservices support. Multiple transports, service discovery, and more.

🎭 CQRS Support

Implement Command Query Responsibility Segregation with event sourcing, projections, and sagas.

🔄 API Gateway

Transform into an API gateway to orchestrate external services with circuit breakers and saga support.

Quick Example

import { createApi, Schema } from 'json-rest-api'
import express from 'express'

const app = express()
const api = createApi({ 
  storage: 'memory',
  http: { app }
})

api.addResource('users', new Schema({
  name: { type: 'string', required: true },
  email: { type: 'string', format: 'email' },
  age: { type: 'number', min: 0 }
}))

app.listen(3000, () => {
  console.log('API running at http://localhost:3000/api/users')
})

That’s it! You now have a fully functional REST API with:

Try It Out

# Create a user
curl -X POST http://localhost:3000/api/users \
  -H "Content-Type: application/json" \
  -d '{"data":{"attributes":{"name":"Alice","email":"alice@example.com","age":28}}}'

# List all users
curl http://localhost:3000/api/users

# Get a specific user
curl http://localhost:3000/api/users/1

# Update a user
curl -X PATCH http://localhost:3000/api/users/1 \
  -H "Content-Type: application/json" \
  -d '{"data":{"attributes":{"age":29}}}'

# Delete a user
curl -X DELETE http://localhost:3000/api/users/1
