Email Auth for Val Town ⚠️ Require a pro account (needed to send email to users) Usage Create an http server, and wrap it in the emailAuth middleware. 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: 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) ! TODO [ ] Add expiration for verification codes and session tokens [ ] use links instead of code for verification [ ] improve errors pages

Code on Val Town Adds a "Code on Val Town" ribbon to your page. This lets your website visitors navigate to the code behind it. This uses github-fork-ribbon-css under the hood. Usage Here are 2 different ways to add the "Code on Val Town" ribbon: 1. Wrap your fetch handler (recommended) import { modifyFetchHandler } from "https://esm.town/v/andreterron/codeOnValTown?v=50";
import { html } from "https://esm.town/v/stevekrouse/html?v=5";
export default modifyFetchHandler(async (req: Request): Promise<Response> => {
return html(`<h2>Hello world!</h2>`);
}); Example: @andreterron/openable_handler 2. Wrap your HTML string import { modifyHtmlString } from "https://esm.town/v/andreterron/codeOnValTown?v=50";
import { html } from "https://esm.town/v/stevekrouse/html?v=5";
export default async (req: Request): Promise<Response> => {
return html(modifyHtmlString(`<h2>Hello world!</h2>`));
}; Example: @andreterron/openable_html Other ways We made sure this was very modular, so you can also add the ribbon using these methods: Get the element string directly: @andreterron/codeOnVT_ribbonElement Modify an HTTP Response: @andreterron/codeOnVT_modifyResponse Use .pipeThrough to append to a stream: @andreterron/InjectCodeOnValTownStream Customization Linking to the val These functions infer the val using the call stack or the request URL. If the inference isn't working, or if you want to ensure it links to a specific val, pass the val argument: modifyFetchHandler(handler, {val: { handle: "andre", name: "foo" }}) modifyHtmlString("<html>...", {val: { handle: "andre", name: "foo" }}) Styling You can set the style parameter to a css string to customize the ribbon. Check out github-fork-ribbon-css to learn more about how to style the element. modifyFetchHandler(handler, {style: ".github-fork-ribbon:before { background-color: #333; }"}) modifyHtmlString("<html>...", {style: ".github-fork-ribbon:before { background-color: #333; }"}) Here's how you can hide the ribbon on small screens: modifyFetchHandler(handler, {style: `@media (max-width: 768px) {
.github-fork-ribbon {
display: none !important;
}
}`}) To-dos [ ] Let users customize the ribbon. Some ideas are the text, color or placement.
