📎 Adding support for Astro

[anonrig]

Description

It would be really good to add support for Astro. (https://astro.build)

I'm guessing this will have to wait for css and html support first, if I read the Language support Biome page correctly:

HTML super languages support

These languages require CSS, HTML and JavaScript parsing to be supported properly. Once those parsers are available, the works around these super languages can start.

Knowing the Biome website is written with Astro, this is a no brainer :-)

I'm OK with linting and parsing the JS/TS parts first.

+1 on this.

I think it would be really useful to have a first simple version of this where only the JS/TS content in the frontmatter is validated/formatted.

Second the idea :)

Currently biome reports some false positives. e.g.: noUnusedVariables

---
const { title } = Astro.props;
---

<title>{title}</title>
