Hi @coarse dragon. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
#importing css file in public in an endpoint
jade heartBOT
If you are creating an API endpoint in Astro (e.g., src/pages/api/endpoint.json.ts), the endpoint returns data (like JSON or binary), not HTML. Including a <link rel="stylesheet" ...> tag in the response body of an API endpoint will not apply any CSS, because the response is not rendered as an HTML page by the browser—it is just data.
If you want to serve a CSS file from the public/ directory, you should reference it by its absolute URL path in your HTML templates, not in an API endpoint. For example, in an Astro page or component, you would use:
<link rel="stylesheet" href="/reset200802.css" type="text/css" />
This works because files in the public/ directory are served as static assets and can be referenced directly by their path from the site root Project structure: public/.
Key points:
- API endpoints are for serving data, not HTML or CSS.
- To use a CSS file from
public/, reference it in your HTML, not in an endpoint response Load a static stylesheet via “link” tags. - If you want to return HTML from an endpoint, you must set the correct
Content-Typeand include the full HTML structure, but this is not a typical use case for Astro endpoints.
If you need to style an HTML page, add the <link> tag in your page or layout component’s <head>, not in an API endpoint. If you need to serve the CSS file itself, just place it in public/ and it will be available at /<filename>.css.
If you have a different use case in mind, please clarify!
Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

I am returning a pdf buffer from the endpoint and what I do is this with css file:
const htmlWithReset = <!DOCTYPE html> <html> <head> <style> div[data-noshow=true] { display: none; } .markdown-body { color-scheme: inherit !important; background-color: inherit !important; } </style> <link rel="stylesheet" href="reset200802.css" type="text/css" /> </head> <body> ${compiledHTML} </body> </html> ;
this html is sent to puppeteer to generate a pdf and i am returning pdf buffer. it doesn't work

Let me check the knowledge base for you again. One moment! :books:
Sorry @coarse dragon, I seem to be having a bit of trouble. Don't worry though, I've pinged my support and they will try to fix me up! :technologist:
Perhaps try again in 15mins?

Based on the knowledge sources, here’s what’s happening:
When you use
<link rel="stylesheet" href="reset200802.css" type="text/css" />
the browser (or Puppeteer) will look for reset200802.css relative to the current URL. In Astro, files in the public/ directory are served from the site root, so you must use an absolute path:
<link rel="stylesheet" href="/reset200802.css" type="text/css" />
This ensures the CSS file is correctly resolved, whether you’re running locally or in production Project structure: public/ Load a static stylesheet via “link” tags.
Key points:
- Always use an absolute path (starting with
/) for files inpublic/when referencing them in HTML. - Relative paths like
"reset200802.css"will not work as expected unless the HTML is served from the root directory, which is not the case for most endpoints.
Example fix:
const htmlWithReset = `
<!DOCTYPE html>
<html>
<head>
<style>
div[data-noshow=true] { display: none; }
.markdown-body {
color-scheme: inherit !important;
background-color: inherit !important;
}
</style>
<link rel="stylesheet" href="/reset200802.css" type="text/css" />
</head>
<body>
${compiledHTML}
</body>
</html>
`;
This should allow Puppeteer to correctly load the CSS from your Astro site’s public/ directory.
If you are running Puppeteer in an environment where it cannot access your local server, you may need to provide a full URL (e.g., <http://localhost:3000/reset200802.css>) or inline the CSS directly into the <style> tag.
If you need to inline the CSS, you can read the file contents and inject it:
const resetCss = fs.readFileSync('public/reset200802.css', 'utf8');
const htmlWithReset = `
<!DOCTYPE html>
<html>
<head>
<style>
${resetCss}
div[data-noshow=true] { display: none; }
.markdown-body {
color-scheme: inherit !important;
background-color: inherit !important;
}
</style>
</head>
<body>
${compiledHTML}
</body>
</html>
`;
