Lastlogin Authentication for val.town

Looking for an hono integration ? See @pomdtr/lastloginHono

Support login in trough:

• Email Link
• QR Code
• Google Oauth
• Github Oauth
• Gitlab Oauth
• Facebook Oauth

You can try a demo at https://pomdtr-lastloginhonoexample.web.val.run (see @pomdtr/lastLoginHonoExample for code)

Wrap your http handlers in a lastlogin middleware (sessions will be persisted in the lastlogin_session table on your sqlite account).

If you want to be the only one able to access your val, you can use @pomdtr/verifyUserEmail.

Create val
import { lastlogin } from "https://esm.town/v/pomdtr/lastlogin";
import { verifyUserEmail } from "https://esm.town/v/pomdtr/verifyUserEmail";

export default lastlogin((req) => {
  return new Response(`You are logged in as ${req.headers.get("X-LastLogin-Email")}`);
}, {
  // check that the user email match your val town email
  verifyEmail: verifyUserEmail
});

If you want to customize how is allowed to signup, you can set the verifyEmail option:

Create val
import { lastlogin } from "https://esm.town/v/pomdtr/lastlogin";

export default lastlogin((req) => {
  return new Response(`You are logged in as ${req.headers.get("X-LastLogin-Email")}`);
}, {
  verifyEmail: (email) => { email == "steve@valtown" }
});

You can allow anyone to signup by returning a boolean from the verifyEmail function:

Create val
import { lastlogin } from "https://esm.town/v/pomdtr/lastlogin";

export default lastlogin((req) => {
  return new Response(`You are logged in as ${req.headers.get("X-LastLogin-Email")}`);
}, {
  verifyEmail: (_email) => true
});

Create val
import { lastlogin } from "https://esm.town/v/pomdtr/lastlogin";
import { verifyUserEmail } from "https://esm.town/v/pomdtr/verifyUserEmail";

export default lastlogin(() => {
  return new Response("Hi!");
}, {
  verifyEmail: verifyUserEmail,
  public_routes: ["/", "/public/*"],
});

See the URLPattern API for reference.

Just redirect the user to /auth/logout
