v1.0.0Introduction
When development is finished, the Node.js application must move from a personal computer to a live web server. Developers use cloud platforms to host their code so anyone in the world can access the website or API 24/7.
Key Points
- Always set the environment variable `NODE_ENV` to `production`.
- Let the hosting service choose the port using `process.env.PORT`.
- Popular hosts include Render, Heroku, Vercel, and DigitalOcean.
- Process managers like PM2 keep the server running after crashes.
