Val Town API URL When Val Town code is run on Val Town servers we use a local URL so we can save time by skipping a roundtrip to the public internet. However, if you want to run your vals that use our API, ie std library vals, locally, you'll want to use our public API's URL, https://api.val.town . We recommend importing and using std/API_URL whenever you use our API so that you are always using the most efficient route. Example Usage import { API_URL } from "https://esm.town/v/std/API_URL";
const response = await fetch(`${API_URL}/v1/me`, {
headers: {
Authorization: `Bearer ${Deno.env.get("valtown")}`,
Accept: "application/json",
},
});
const data = await response.json();
console.log(data)

html: create sanitized HTML using tagged templates Examples import { html } from "https://esm.town/v/postpostscript/html"
const unsafeInput = "<script>alert(1)</script>"
console.log(html`Value: ${unsafeInput}`)
// Value: <script>alert(1)</script> These can be combined -- HTML marked as safe (instance is RawHTML ) will be directly inserted: const scripts = html`<script>alert(1)</script>`
console.log(html`<head>
${scripts}
</head>`.toString())
// <head>
// <script>alert(1)</script>
// </head> To easily create HTTP Response outputs like @stevekrouse/html, use the htmlResponse utility: import { html, htmlResponse } from "https://esm.town/v/postpostscript/html";
export default function(req: Request) {
return htmlResponse`
Request URL: ${decodeURIComponent(req.url)}
`;

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. Blob Admin Panels Blob Storage in Settings – built-into Val Town - list, download, delete blobs Blob Admin – search, view, edit, upload blobs – built in a val – easy to customize in Val Town! Usage 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
