Node.js Server

Discover the Node.js server preset with Nitro to deploy on any Node hosting.

::list

• Default output format if none is specified or auto-detected
  
• Loads only the required chunks to render the request for optimal cold start timing
  
• Useful for deploying Nuxt apps to any Node.js hosting ::

Entry Point

When running nuxt build with the Node server preset, the result will be an entry point that launches a ready-to-run Node server.

node .output/server/index.mjs

Example

$ node .output/server/index.mjs
Listening on http://localhost:3000

Configuring Defaults at Runtime

This preset will respect the following runtime environment variables:

• NITRO_PORT or PORT (defaults to 3000)
• NITRO_HOST or HOST (defaults to '0.0.0.0')
• NITRO_SSL_CERT and NITRO_SSL_KEY - if both are present, this will launch the server in HTTPS mode. In the vast majority of cases, this should not be used other than for testing, and the Nitro server should be run behind a reverse proxy like nginx or Cloudflare which terminates SSL.

Using PM2

To use pm2, use an ecosystem.config.js:

module.exports = {
  apps: [
    {
      name: 'NuxtAppName',
      exec_mode: 'cluster',
      instances: 'max',
      script: './.output/server/index.mjs'
    }
  ]
}

Using Cluster Mode

You can use NITRO_PRESET=node_cluster in order to leverage multi-process performance using Node.js cluster module.

By default, the workload gets distributed to the workers with the round robin strategy.
