URI

URI is a URL interface that does not require a base URL. ^{1 2 3}

1npm install relative-url-interface

1import URI from 'relative-url-interface'
2
3const uri = new URI('../assets/kitten.jpg')
4
5String(uri) // "../assets/kitten.jpg"

The URI class extends URL and can be used as a drop-in replacement. It is powered by spec-url, and it is ideal for server-side code, pre-compiled code, or any situation where absolute URLs may not be known.

1import URI from 'relative-url-interface'
2
3const puppy_page = new URI('file://path/to/site/src/pages/puppy.astro')
4const kitty_image = URI.from('../assets/kitten.jpg')
5
6const absolute_kitten = new URI(kitty_image, puppy_page)
7
8fs.readFile(absolute_kitten, 'utf8') // contents of "file://path/to/site/src/assets/kitten.jpg"
