Server deployment steps for a Node.js project: Prepare the deployment environment: obtain server access, install Node.js, set up a Git repository. Build the application: Use npm run build to generate deployable code and dependencies. Upload code to the server: via Git or File Transfer Protocol. Install dependencies: SSH into the server and use npm install to install application dependencies. Start the application: Use a command such as node index.js to start the application, or use a process manager such as pm2. Configure a reverse proxy (optional): Use a reverse proxy such as Nginx or Apache to route traffic to your application
