Map URLs to source files for intelligent dynamic sampling. Framework integrations discover routes automatically; CLI users may need manual configuration for optimal sampling.

Pages directory

By default, the pages/ dir is scanned for files with extensions .vue and .md, from the root directory.

If your project has a different setup you can modify the configuration.

import { defineUnlighthouseConfig } from 'unlighthouse/config'

export default defineUnlighthouseConfig({
  root: './app',
  discovery: {
    pagesDir: 'routes',
    fileExtensions: ['jsx', 'md'],
  },
})

Custom sampling

When you have URL patterns which don't use URL segments or the mapping is failing, it can be useful to map the sampling yourself.

By using the customSampling option you map regex to a route definition.

In the below example we will map any URL such as /q-search-query, /q-where-is-the-thing to a single route definition, which allows the sampling to work.

export default defineUnlighthouseConfig({
  scanner: {
    customSampling: {
      '/q-(.*?)': {
        name: 'search-query',
      },
    },
  },
})
