As we discussed before, Rakkas relies on HatTip for handling HTTP so we will use the @hattip/cookie package to manage cookies:
import { Head, PageProps, HeadersFunction } from "rakkasjs"; export default function LoginPage({ url }: PageProps) { const error = url.searchParams.get("error"); if (error) { return
Error: {error}div>; } return ({/* Redirect immediately */} Head>Redirecting...p> div> ); } export const headers: HeadersFunction = async ({ url, requestContext: ctx, }) => { if (url.searchParams.get("error")) { return { status: 403 }; } const code = url.searchParams.get("code"); const state = url.searchParams.get("state"); if (code && state === ctx.cookie.state) { const { access_token: token } = await fetch( "https://github.com/login/oauth/access_token" + `?client_id=${process.env.GITHUB_CLIENT_ID}` + `&client_secret=${process.env.GITHUB_CLIENT_SECRET}` + `&code=${code}`, { method: "POST", headers: { Accept: "application/json" }, } ).then((r) => r.json<{ access_token: string }>()); if (token) { ctx.setCookie("token", token, { httpOnly: true, secure: import.meta.env.PROD, sameSite: "strict", maxAge: 60 * 60, }); return { // We won't be setting any headers, // setCookie will do it for us, // so an empty object is fine. }; } } // Login failed for some reason // We'll redirect to set the `error` parameter return { status: 302, headers: { Location: new URL(`/login?error=Login%20failed`, url).href, }, }; };
