The dev property

Define the development or production mode.


  • Type: Boolean
  • Default: true

This property is overwritten by the nuxt commands:

  • dev is forced to true with nuxt
  • dev is forced to false with nuxt build, nuxt start and nuxt generate

This property should be used when using Nuxt programmatically:

nuxt.config.js

  1. export default {
  2. dev: process.env.NODE_ENV !== 'production'
  3. }

server.js

  1. const { Nuxt, Builder } = require('nuxt')
  2. const app = require('express')()
  3. const port = process.env.PORT || 3000
  4. // We instantiate Nuxt with the options
  5. const config = require('./nuxt.config.js')
  6. const nuxt = new Nuxt(config)
  7. app.use(nuxt.render)
  8. // Build only in dev mode
  9. if (config.dev) {
  10. new Builder(nuxt).build()
  11. }
  12. // Listen the server
  13. app.listen(port, '0.0.0.0').then(() => {
  14. console.log(`Server is listening on port: ${port}`)
  15. })

package.json

  1. {
  2. "scripts": {
  3. "dev": "node server.js",
  4. "build": "nuxt build",
  5. "start": "NODE_ENV=production node server.js"
  6. }
  7. }
