API: nuxt.render(req, res)

• Type: Function
• Arguments:
  • Request
  • Response
• Returns: Promise

You can use Nuxt.js as a middleware with nuxt.render for your node.js server.

Example with Express:

const { Nuxt, Builder } = require('nuxt')
const app = require('express')()
const isProd = (process.env.NODE_ENV === 'production')
const port = process.env.PORT || 3000
// We instantiate Nuxt.js with the options
const config = require('./nuxt.config.js')
config.dev = !isProd
const nuxt = new Nuxt(config)
// Render every route with Nuxt.js
app.use(nuxt.render)
// Build only in dev mode with hot-reloading
if (config.dev) {
  new Builder(nuxt).build()
    .then(listen)
} else {
  listen()
}
function listen () {
  // Listen the server
  app.listen(port, '0.0.0.0')
  console.log('Server listening on `localhost:' + port + '`.')
}

It's recommended to call nuxt.render at the end of your middlewares since it will handle the rendering of your web application and won't call next()
