astro-css-components
⚠️ Very early in development, more of a proof of concept than a real thing at the moment ⚠️
Add "CSS Components" support to Astro, inspired by eleventy-assets. This allows you to for instance, add page specific CSS. In my personal blog, I use it to add the CSS needed for syntax coloring only to the page that have code in them
The API is currently.. not very good. Use at your own caution - it should works, however
Usage
Page.astro
---
import BaseLayout from "BaseLayout.astro"
import { CSSComponent } from "astro-css-components"
---
<CSSComponent register={{ name: "should-be-red", content: ".should-be-red {color: red;}" }} />
<BaseLayout>
<article>
<div class="should-be-red">My super text</div>
</article>
</BaseLayout>BaseLayout.astro
---
import { CSSComponent } from "astro-css-components"
---
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<CSSComponent getForURL />
</head>
<body>
<slot />q
</body>
</html>Result
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<style>.should-be-red {color: red;}</style>
</head>
<body>
<article>
<div class="should-be-red">My super text</div>
</article>
</body>
</html>
API
The CSSComponent component takes the following props:
register
Used to register a new component, it takes an object with the following attributes:
- name: Name of your component
- content: CSS style your component has
OR
- contentFile: File which contain your CSS, path must be relative from the root of your project
Unless used with global, the component will be tied to the current URL
Examples:
<CSSComponent register={{ name: "should-be-red", content: ".should-be-red {color: red;}" }} /><CSSComponent register={{ name: "code", contentFile: "src/theme/css/modules/code.css" }} />global
By adding this props, you can make the component global, this mean you can call it from everywhere using getByName
Example:
<CSSComponent global register={{ name: "should-be-blue", content: ".should-be-blue {color: blue;}" }} />conditional
By adding this props, you can only register the component when a certain condition is met
Example:
<CSSComponent register={{ name: "should-be-orange", content: ".should-be-orange {color: orange;}" }} conditional={page.loadCSSModules.includes("orange")} />minify
By adding this props, the CSS will be minified through csso
Example:
<CSSComponent minify register={{ name: "should-be-purple", content: ".should-be-purple {color: purple;}" }} />getForURL
Get the components for the current URL, this get all the components registered for the current URL, to get a specific component, use getByName
Example:
<CSSComponent getForURL />getByName
Get a specific component by name, this look in both the library for the current url and the global one
Example:
<CSSComponent getByName="should-be-yellow" />
