I brutally eradicated js from my blog for fun and profit

This blog is built with Nuxt.js.

Nuxt is awesome from development perspective and it's great for SEO too, since it generates all the pages statically to make crawlers happy.

But, Google PageSpeed is not really happy with it:

The above is the blog list page and below is an article:

It turns out that Google PageSpeed doesn't like many little JS includes, that are meant to hydrating the blog for a better user navigation and experience.

I wanted to test a version without javascript at all, quickly.

Instead of digging with the Nuxt internals, plugin system or some unknown builder setting, I've opted for the brutal way:

A Node.js script that parses all the generated pages, finding all the script tags, stripping 'em all!

And here the result of the same pages from Google PageSpeed:


Not bad at all!

Here the relevant part of the Node.js script for the curious:

const fs = require('fs')

const files = getAllFiles('./dist')

files.forEach(file => {
  let f = fs.readFileSync(file, 'utf-8')
  f = f.replace(/<script.*?<\/script>/mig, '')
  f = f.replace(/<link rel="preload" href=.*?as="script">/mig, '')
  fs.writeFileSync(file, f, 'utf-8')
