Runtime Comparison between Node.js, Deno and Bun

This project demonstrates how to set up HTTP servers using three different runtimes: Node.js, Deno, and Bun in a monorepo structure and benchmark them.

Prerequisites

To run the servers, ensure you have the following installed:

Node.js

# Linux & macOS
curl -fsSL https://fnm.vercel.app/install | bash
source ~/.bashrc
fnm use --install-if-missing 23

# Windows
winget install Schniz.fnm
fnm env --use-on-cd | Out-String | Invoke-Expression
fnm use --install-if-missing 23

Deno

# Linux & macOS
curl -fsSL https://deno.land/install.sh | sh

# Windows
irm https://deno.land/install.ps1 | iex

Bun

# Linux & macOS
curl -fsSL https://bun.sh/install | bash

# Windows
powershell -c "irm bun.sh/install.ps1 | iex"

Project Structure

The project is structured as a monorepo with three separate server implementations:

/runtime-comparison
├── /packages
│   ├── /node-server
│   ├── /deno-server
│   ├── /bun-server
└── /package.json

• Node Server: A simple HTTP server using Node.js.
• Deno Server: A simple HTTP server using Deno.
• Bun Server: A simple HTTP server using Bun.

Instalation process

# Clone repository
git clone git@github.com:its-gabo/runtime-comparison.git

# Install dependencies
bun install

# Running server
bun run start:{runtimeName}

Benchmarking runtimes

To benchmark the runtimes you can use hey.

hey -c 10 -z 10s http://localhost:3000/

# -c number of workers to run concurrently
# -z time of running (e.g 10s = 10 seconds)
