api route cookie set

[supple imp]

Hi @bright hollow. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

It seems like you are trying to use context.cookies.set() to set a cookie, but the error you're encountering is because context.cookies is not available in the given code. In Astro, you should use Astro.cookies to read and manipulate cookies when working with server-side rendering.

Here's an example of how to use Astro.cookies:

---
let counter = 0

if(Astro.cookies.has("counter")){
 const cookie = Astro.cookies.get("counter")
 counter = cookie.number() + 1
}

Astro.cookies.set("counter", counter)

You can find more information about Astro.cookies in the Astro documentation (https://docs.astro.build/en/reference/api-reference#astrocookies).

In an API route, you can set a cookie using the Response object's headers property. Here's an example of how to set a cookie in an API route:

export function get({ request }) {
  const url = new URL(request.url);
  const newLanguage = url.searchParams.get("lang");
  if (!newLanguage) {
    return new Response(
      JSON.stringify({
        message: "Missing required fields",
      }),
      { status: 400 }
    );
  }

  const response = new Response(
    JSON.stringify({
      message: "success",
    }),
    { status: 200 }
  );

  response.headers.set('Set-Cookie', `lang=${newLanguage}; Path=/;`);

  return response;
}

In this example, we're using response.headers.set('Set-Cookie', ...) to set the lang cookie with the value of newLanguage. You can find more information about setting headers in the Astro documentation (https://docs.astro.build/en/reference/api-reference#astroresponse).
