\n First name\n setName(e.target.value)}\n type=\"text\"\n required={true}\n />\n Email\n setEmail(e.target.value)}\n type=\"email\"\n required={true}\n />\n \n \n );\n};\n```\n\nYou can see a full example on petemillspaugh.com: [signup in the footer](https://www.petemillspaugh.com/) and [code on github](https://github.com/pmillspaugh/petemillspaugh.com/blob/main/src/components/EmailSignup/EmailSignup.tsx).\n\nYou can add/remove input fields as you wish, of course (e.g. maybe you don't need a name, or maybe you want a how'd-you-hear-about-us field). Just adjust the SQL and frontend implementation accordingly.\n\n## Frontend confirmation page\n\nCreate a confirmation page that accepts an email and token as query params and calls the `/confirm-verification` endpoint. Simple example using React (and Next.js /page directory):\n\n```tsx\nconst EmailConfirmationPage = () => {\n const router = useRouter();\n const { email, token } = router.query;\n const [isConfirmed, setIsConfirmed] = useState(false);\n\n useEffect(() => {\n async function confirmEmail() {\n if (!email || !token) return;\n\n const response = await fetch(`https://petermillspaugh-emailSubscription.web.val.run/confirm-verification?email=${email}&token=${token}`, {\n method: \"PUT\",\n });\n const { confirmed } = await response.json();\n if (confirmed) setIsConfirmed(true);\n }\n\n confirmEmail();\n }, [email, token]);\n\n if (!isConfirmed) return null;\n\n return (\n

You’re all set!

\n );\n};\n```\n\nFull example is [here](https://www.petemillspaugh.com/email-confirmation) and code is [here](https://github.com/pmillspaugh/petemillspaugh.com/blob/main/src/components/EmailConfirmation/EmailConfirmation.tsx).\n\nAs an alternative, you could make `/confirm-verification` a GET route and have your email confirmation link sent by the first route be `https://petermillspaugh-emailSubscription.web.val.run/confirm-verification?email=${email}&token=${token}` (swapping in your namespace). That would be marginally faster, probably, but you'd still need some way to convey confirmation to the user (e.g. add some \"You're all set\" message to the return). Plus, the route writes to the `subscribers` table, so a PUT feels more appropriate.\n\n## Notes\n\n- Sending emails to people other than yourself on Val Town is a paid feature—if you want to stay on the free plan, you can go with a package like [nodemailer](https://www.npmjs.com/package/nodemailer) or [@sendgrid/mail](https://www.npmjs.com/package/@sendgrid/mail)","valType","http","currentVersion","c73c6830-c1e3-11ee-a1b4-325518e2651b","id","code","import { fetchVerificationEmailHtml } from \"https://esm.town/v/petermillspaugh/fetchVerificationEmailHtml\";\nimport { refreshVerificationToken } from \"https://esm.town/v/petermillspaugh/refreshVerificationToken\";\nimport { sendVerificationEmail } from \"https://esm.town/v/petermillspaugh/sendVerificationEmail\";\nimport { upsertEmailSubscriber } from \"https://esm.town/v/petermillspaugh/upsertEmailSubscriber\";\nimport { email as sendEmail } from \"https://esm.town/v/std/email?v=11\";\nimport { sqlite } from \"https://esm.town/v/std/sqlite?v=4\";\nimport { Hono } from \"npm:hono\";\n\nexport async function emailSubscription(req: Request) {\n const app = new Hono();\n\n app.post(\"/send-verification\", async c => {\n const formData = await c.req.formData();\n const name = formData.get(\"name\");\n const email = formData.get(\"email\");\n\n if (typeof name !== \"string\" || typeof email !== \"string\") {\n return Response.json({ message: \"Unexpected missing value for name or email.\" });\n }\n\n const token = crypto.randomUUID();\n await upsertEmailSubscriber({ name, email, token });\n\n // Lack of await is intentional: send optimistic success response, then send email and notify myself async\n sendVerificationEmail({ emailAddress: email, html: fetchVerificationEmailHtml({ email, token }) });\n\n return Response.json({ success: true, message: \"Sent verification email.\" });\n });\n\n app.put(\"/confirm-verification\", async c => {\n const email = c.req.query(\"email\");\n const token = c.req.query(\"token\");\n\n const { newToken, didRefresh } = await refreshVerificationToken({ email, token });\n if (didRefresh) {\n // Lack of await is intentional: send optimistic success response, then send email and notify myself async\n sendVerificationEmail({\n emailAddress: email,\n html: fetchVerificationEmailHtml({ email, token: newToken, reVerifying: true }),\n });\n\n return Response.json({ message: \"Resent confirmation email.\" });\n }\n\n await sqlite.execute({\n sql: `UPDATE subscribers SET verified = 1 WHERE email = ?;`,\n args: [email],\n });\n\n // No need to await: just emailing myself a notification\n sendEmail({\n subject: `${email} verified for petemillspaugh.com subscription`,\n text: `Verification complete for ${email}'s subscription to petemillspaugh.com`,\n });\n\n return Response.json({ confirmed: true, message: \"Verified email address.\" });\n });\n\n app.get(\"/\", async c => {\n return c.html(`\n \n \n Sign up for petemillspaugh.com\n \n \n
