• Type: Object

Nuxt.js let you define the server connection variables for your application inside nuxt.config.js.

Basic example:

export default {
  server: {
    port: 8000, // default: 3000
    host: '0.0.0.0', // default: localhost,
    timing: false
  }
}

This lets you specify the host and port for your Nuxt.js server instance.

Example using HTTPS configuration

import path from 'path'
import fs from 'fs'

export default {
  server: {
    https: {
      key: fs.readFileSync(path.resolve(__dirname, 'server.key')),
      cert: fs.readFileSync(path.resolve(__dirname, 'server.crt'))
    }
  }
}

You can find additional information on creating server keys and certificates on localhost on certificates for localhost article.

Example using sockets configuration

export default {
  server: {
    socket: '/tmp/nuxt.socket'
  }
}

timing

• Type: Object or Boolean
• Default: false

Enabling the server.timing option adds a middleware to measure the time elapsed during server-side rendering and adds it to the headers as 'Server-Timing'

Example using timing configuration

server.timing can be an object for providing options. Currently, only total is supported (which directly tracks the whole time spent on server-side rendering)

export default {
  server: {
    timing: {
      total: true
    }
  }
}

Using timing api

The timing api is also injected into the response on server-side when server.time is enabled.

Syntax

res.timing.start(name, description)
res.timing.end(name)

Example using timing in servermiddleware

export default function (req, res, next) {
  res.timing.start('midd', 'Middleware timing description')
  // server side operation..
  // ...
  res.timing.end('midd')
  next()
}

Then server-timing head will be included in response header like:

Server-Timing: midd;desc="Middleware timing description";dur=2.4

Please refer to Server-Timing MDN for more details.
