Email Auth for Val Town

⚠️ Require a pro account (needed to send email to users)

Create an http server, and wrap it in the emailAuth middleware.

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

export default emailAuth((req) => {
  return new Response(`your mail is ${req.headers.get("X-User-Email")}`);
}, {
    verifyEmail: verifyUserEmail
});

💡 If you do not want to put your email in clear text, just move it to an env var (ex: Deno.env.get("email"))

If you want to allow anyone to access your val, just use:

Create val
import { emailAuth } from "https://esm.town/v/pomdtr/email_auth"

export default emailAuth((req) => {
  return new Response(`your mail is ${req.headers.get("X-User-Email")}`);
}, {
    verifyEmail: (_email) => true
});

Each time someone tries to access your val but is not allowed, you will get an email with:

• the email of the user trying to log in
• the name of the val the he want to access

You can then just add the user to your whitelist to allow him in (and the user will not need to confirm his email again) !

• Add expiration for verification codes and session tokens
• use links instead of code for verification
• improve errors pages
