Password Auth Middleware Protect your vals behind a password. Use session cookies to persist authentication. Demo See @pomdtr/password_auth_test Usage import { passwordAuth } from "https://esm.town/v/pomdtr/password_auth?v=84"; export default passwordAuth(() => { return new Response("OK"); }, { verifyPassword: (password) => password == Deno.env.get("VAL_PASSWORD") }); If you want to use an api token to authenticate: import { passwordAuth } from "https://esm.town/v/pomdtr/password_auth?v=84"; import { verifyToken } from "https://esm.town/v/pomdtr/verifyToken"; export default passwordAuth(() => { return new Response("OK"); }, { verifyPassword: verifyToken }); TODO [x] allow to authenticate using a val town token [ ] add a way to send an email to ask a password from the val owner [ ] automatically extend the session [ ] automatically remove expired sessions FAQ How to sign out ? Navigate to <your-site>/signout .

Val Town Basic Auth Add basic auth on top of any http val Usage Wrap your HTTP handler in the basicAuth middleware. import { basicAuth } from "https://esm.town/v/pomdtr/basicAuth"; function handler(req: Request) { return new Response("You are authenticated!"); } export default basicAuth(handler, { verifyUser: (username, password) => username == "user" && password == "password" }); If you want to use an apiToken as a password: import { basicAuth } from "https://esm.town/v/pomdtr/basicAuth"; import { verifyToken } from "https://www.val.town/v/pomdtr/verifyToken" function handler(req: Request) { return new Response("You are authenticated!"); } export default basicAuth(handler, { verifyUser: (_, password) => verifyToken(password) });

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

Blob Storage - Docs ↗ Val Town comes with blob storage built-in. It allows for storing any data, like text, JSON, or images. You can access it via std/blob . Blob storage is scoped globally to your account. If you set a blob in one val, you can retrieve it by the same key in another val. It's backed by Cloudflare R2. You may find this admin viewer helpful for viewing and editing your blobs. Get JSON import { blob } from "https://esm.town/v/std/blob"; let blobDemo = await blob.getJSON("myKey"); console.log(blobDemo); // returns `undefined` if not found Set JSON import { blob } from "https://esm.town/v/std/blob"; await blob.setJSON("myKey", { hello: "world" }); List keys import { blob } from "https://esm.town/v/std/blob"; let allKeys = await blob.list(); console.log(allKeys); const appKeys = await blob.list("app_"); console.log(appKeys); // all keys that begin with `app_` Delete by key import { blob } from "https://esm.town/v/std/blob"; await blob.delete("myKey"); Examples Counter RSS Notifications (saving the last run time) Picture: Save & Read Error Handling blob.get can throw ValTownBlobNotFoundError Any method can throw ValTownBlobError for unexpected errors. Utilities Our Blob SDK also includes some utility functions to make working with blobs easier. Copy import { blob } from "https://esm.town/v/std/blob"; await blob.copy("myKey", "myKeyCopy"); Move import { blob } from "https://esm.town/v/std/blob"; await blob.move("myKey", "myKeyNew"); Lower-level API We provide access to the lower-level getter and setters, which are useful if you are storing non-JSON or binary data, need to stream in your response or request data, or do anything else lower-level. async get(key: string) : Retrieves a blob for a given key. async set(key: string, value: string | BodyInit) : Sets the blob value for a given key. See BodyInit . Limitations Blob-stored data counts towards your total Val Town storage – 10mb on the free plan and 1gb on pro. Check our pricing page to learn more. Keys for blobs can be up to 512 characters long. 📝 Edit docs

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.
