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

Email - Docs ↗ Send emails with std/email . You can only send emails to yourself if you're on Val Town Free. If you're on Val Town Pro , you can email anyone. Want to receive emails instead? Create an email handler val Basic usage import { email } from "https://esm.town/v/std/email"; await email({ subject: "New Ink & Switch Post!", text: "https://www.inkandswitch.com/embark/" }); subject The email subject line. It defaults to Message from @your_username on Val Town . to , cc , and bcc By default, the to field is set to the owner of the Val Town account that calls it. If you have Val Town Pro, you can send emails to anyone via the to , cc , and bcc fields. If you don't have Val Town Pro, you can only send emails to yourself, so leave those fields blank. from The from is limited to a few options: It defaults to notifications@val.town if you don't specify it. If you do specify it, it must be of the form: your_username.valname@valtown.email . replyTo replyTo accepts a string email or an object with strings for email and name (optional). This can be useful if you are sending emails to others with Val Town Pro. import { email } from "https://esm.town/v/std/email"; await email({ to: "someone_else@example.com", from: "your_username.valname@valtown.email", replyTo: "your_email@example.com", text: "these pretzels are making me thirsty", }); Attachments You can attach files to your emails by using the attachments field. Attachments need to be Base64 encoded, which is that the btoa method is doing in this example: import { email } from "https://esm.town/v/std/email"; export const stdEmailAttachmentExample = email({ attachments: [ { content: btoa("hello attachments!"), filename: "test.txt", type: "text", disposition: "attachment", }, ], }); Here's an example sending a PDF . 📝 Edit docs

@std.set Deprecated: use @std/blob now instead. Set a val on your account to JSON, which you can use as a key-value store.
