Nuxt.js is a minimalistic framework for server-rendered Vue applications (inspired by Next.js)

📓 How to use

$ npm install nuxt --save

Add a script to your package.json like this:

{
  "scripts": {
    "start": "nuxt"
  }
}

After that, the file-system is the main API. Every .vue file becomes a route that gets automatically processed and rendered.

Populate ./pages/index.vue inside your project:




And then run:

npm start

Go to http://localhost:3000

So far, we get:

  • Automatic transpilation and bundling (with webpack and babel)
  • Hot code reloading
  • Server rendering and indexing of ./pages
  • Static file serving. ./static/ is mapped to /
  • Config file nuxt.config.js
  • Code splitting via webpack

Using nuxt.js programmatically

Nuxt is built on the top of ES2015, which makes the code more enjoyable and cleaner to read. It doesn't make use of any transpilers and depends upon Core V8 implemented features.
For these reasons, nuxt.js targets Node.js 4.0 or higher (you might want to launch node with the --harmony-proxies flag if you running node <= 6.5.0<="" code=""> )

const Nuxt = require('nuxt')

const options = {
  routes: [], // see examples/custom-routes
  css: ['/dist/bootstrap.css'] // see examples/global-css
  store: true // see examples/vuex-store
  plugins: ['public/plugin.js'], // see examples/plugins-vendor
  loading: false or { color: 'blue', failedColor: 'red' } or 'components/my-spinner' // see examples/custom-loading
  build: {
    vendor: ['axios'] // see examples/plugins-vendor
  }
}

// Launch nuxt build with given options
new Nuxt(options)
.then((nuxt) => {
  // You can use nuxt.render(req, res) or nuxt.renderRoute(route, context)
})
.catch((error) {
  // If an error appended while building the project
})

Using nuxt.js as a middleware

You might want to use your own server with you configurations, your API and everything awesome your created with. That's why you can use nuxt.js as a middleware. It's recommended to use it at the end of your middlewares since it will handle the rendering of your web application and won't call next()

app.use(nuxt.render)

Render a specific route

This is mostly used for tests purpose but who knows!

nuxt.renderRoute('/about', context)
.then(function ({ html, error }) {
  // You can check error to know if your app displayed the error page for this route
  // Useful to set the correct status status code if an error appended:
  if (error) {
    return res.status(error.statusCode || 500).send(html)
  }
  res.send(html)
})
.catch(function (error) {
  // And error appended while rendering the route
})

Examples

Please take a look at the examples/ folder.
If you want to launch one example to see it live:

cd node_modules/nuxt/
bin/nuxt examples/hello-world
# Go to http://localhost:3000

Production deployment

To deploy, instead of running nuxt, you probably want to build ahead of time. Therefore, building and starting are separate commands:

nuxt build
nuxt start

For example, to deploy with now a package.json like follows is recommended:

{
  "name": "my-app",
  "dependencies": {
    "nuxt": "latest"
  },
  "scripts": {
    "dev": "nuxt",
    "build": "nuxt build",
    "start": "nuxt start"
  }
}

Then run now and enjoy!

Note: we recommend putting .nuxt in .npmignore or .gitignore.
