Node.js server

👌 Default preset if none is specified or auto-detected
🚀 Loads only the required chunks to render the request for optimal cold start timing
🐛 Useful for debugging

Usage

You can use the Nuxt config to explicity set the preset to use:

export default {
  nitro: {
    preset: 'server'
  }
}

Or directly use the NITRO_PRESET environment variable when running nuxt build:

NITRO_PRESET=server npx nuxt build

Entrypoint

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

node .output/server/index.mjs

Example

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

Server timings

You can enable the nitro.timing option in order to have the logs about the chunk loading and cold start performance.

export default {
  nitro: {
    preset: 'server',
    timing: true
  }
}

$ node .output/server/index.mjs
