Guess.js + Nuxt.js

Guess.js is a collection of libraries & tools for enabling data-driven user-experience on the web.

Nuxt.js is a Vue.js Meta Framework to create complex, fast & universal web applications quickly.

DEMO

In this particular example, we combine Guess.js with Nuxt.js to introduce predictive prefetching of JavaScript bundles. Based on user navigation patterns collected from Google Analytics or other source, Guess.js builds a machine-learning model to predict and prefetch JavaScript that will be required in each subsequent page.

Based on early benchmarks, this can improve the perceived page load performance with 20%.

Usage

$ git clone [email protected]:daliborgogic/guess-nuxt && \
cd guess-nuxt && \
npm i

$ mv .env.example .env
# Update GA in .env

# Dev
$ npm run dev

# Build
$ npm run build

# Start
$ npm start

Integration

Guess.js (0.1.5 and above) works with Nuxt.js with only two points of integration. All you need to do is add the GuessPlugin to nuxt.config.js and introduce a snippet for prefetching the pages which are likely to be visited Nuxt.

The following sections describe both points in details.

Webpack Config

All you need is to extend the webpack config of your Nuxt.js application is to add the GuessPlugin to nuxt.config.js file, located in the root of your project. If the file does not exist, create it and add the following content:

const { GuessPlugin } = require('guess-webpack')
const { GA } = process.env

module.exports = {
  build: {
    extend(config, ctx) {
      if (ctx.isClient) {
        config.plugins.push(
          new GuessPlugin({
          GA,
          runtime: {
            delegate: true
          },
          routeProvider: false
        })
      )
    }
  }
}

The routes that guess() returns depend on the Google Analytics report that it has extracted, together with the user’s effective connection type.
