Question 1

How do I deploy Express.js to a VPS?

Accepted Answer

Deploy Express using PM2 for process management. Upload your code to the VPS, install dependencies with "npm install --production", then run "pm2 start app.js --name express". Configure Nginx as a reverse proxy for SSL and static file serving.

Question 2

How do I run Express in production mode?

Accepted Answer

Set NODE_ENV=production environment variable, use PM2 for process management and automatic restarts, enable compression middleware, configure proper error handling, and use helmet.js for security headers. Never expose the Express port directly - always use Nginx.

Question 3

Should I use Express or Fastify?

Accepted Answer

Express is battle-tested with the largest ecosystem of middleware. Fastify offers better performance and built-in validation. For most projects, Express is sufficient. Choose Fastify for high-performance APIs. Both deploy similarly on a VPS.

Question 4

How do I handle clustering with Express?

Accepted Answer

Use PM2 cluster mode: "pm2 start app.js -i max" to spawn one process per CPU core. Alternatively, use Node.js cluster module directly. Ensure your app is stateless or use Redis for session storage when clustering.
