• Type: Boolean
• Default: true

Define the development or production mode of Nuxt.js.

This property is overwritten by nuxt commands:

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

This property should be used when using Nuxt.js programmatically:

Example:

nuxt.config.js

export default {
  dev: (process.env.NODE_ENV !== 'production')
}

server.js

const { Nuxt, Builder } = require('nuxt')
const app = require('express')()
const port = process.env.PORT || 3000

// We instantiate Nuxt.js with the options
const config = require('./nuxt.config.js')
const nuxt = new Nuxt(config)
app.use(nuxt.render)

// Build only in dev mode
if (config.dev) {
  new Builder(nuxt).build()
}

// Listen the server
app.listen(port, '0.0.0.0').then(() => {
  console.log(`Server is listening on port: ${port}`)
})

Then in your package.json:

{
  "scripts": {
    "dev": "node server.js",
    "build": "nuxt build",
    "start": "NODE_ENV=production node server.js"
  }
}
