🚀 GraphQL Server Performance Showdown

Node.js TypeScript GraphQL

Overview

This project provides a comprehensive performance comparison between three widely-used Node.js GraphQL server implementations:

  • ⚡ Fastify + Mercurius
  • 🚅 Fastify + Apollo
  • 🚂 Express + Apollo

🏃‍ Quick Start

# Clone the repository
git clone https://github.com/mypolat/fastify-mercurius_vs_fastify-apollo_vs_express-apollo
cd fastify-mercurius_vs_fastify-apollo_vs_express-apollo

# Install dependencies
npm install

# Build the project
npm run build

# Start all servers
npm run start:all

# Run benchmark tests
npm run test:all

📊 Performance Comparison

Response Time Analysis

Framework Best Average Worst Recommended Use Case
Fastify + Mercurius ~0.6ms ~0.7ms ~1ms High-performance APIs requiring minimal latency
Fastify + Apollo ~4.8ms ~5.1ms ~14ms Balance between features and performance
Express + Apollo ~5.3ms ~15-40ms ~42ms Existing Express.js applications

🎯 Key Findings
