Introduction

By default, Unlighthouse assumes server-side rendered (SSR) pages where links are discoverable in the initial HTML. Single-page applications require JavaScript execution for proper link discovery and content rendering.

Enable JavaScript Execution

Allow Puppeteer to execute JavaScript before extracting page content:

import { defineUnlighthouseConfig } from 'unlighthouse/config'

export default defineUnlighthouseConfig({
  scanner: {
    skipJavascript: false, // Enable JS execution for SPAs
  },
})
