Cookies

Zeta doesn't provide any functionality around cookies.

Overview

If you need to get or set cookies, you need to do it yourself. Thankfully, cookies are super simple to work with.

I'd recommend using the cookie package from npm. Then you just need to use the Cookie and Set-Cookie headers.

import { createApp } from "@aklinker1/zeta";
import * as cookie from "cookie";

const SESSION_COOKIE_NAME = "example_session";

export const app = createApp()
  .post(
    "/login",
    {
      description: "Log in a user and set the session cookie.",
      body: z.object({
        username: z.string(),
        password: z.string(),
      }),
    },
    ({ body, request, set }) => {
      const user = await authenticate(body.username, body.password);
      const sessionToken = await generateSessionToken(user);

      set.headers["Set-Cookie"] = cookie.serialize(
        SESSION_COOKIE_NAME,
        sessionToken,
        {
          maxAge: 60 * 60 * 24 * 7, // 7 days
          httpOnly: true,
          secure: true,
          sameSite: "strict",
        },
      );
    },
  )
  .get(
    "/session",
    {
      description: "Get the current session based on the session token.",
    },
    ({ request }) => {
      const cookiesString = request.headers.get("cookie");
      const cookies = cookie.parse(cookiesString);
      const sessionToken = cookies[SESSION_COOKIE_NAME];
      return await getUserFromSessionToken(sessionToken);
    },
  );
