Prune a val's versions. Useful if you want to delete a bunch of versions. All versions before keep_since that aren't in keep_versions will be deleted !!! You can run it without passing commit to see a preview of what will happen. Example await prune_val("abcdefg", [3,6,8], 12, true); Could output Val: untitled_peachTakin, Current Version: 15 Deleting Versions: [ 1, 2, 4, 5, 7, 8, 9, 10, 11 ] Deleting Version 1 Deleted Deleting Version 2 Deleted Deleting Version 4 Deleted Deleting Version 5 Deleted Deleting Version 6 Deleted Deleting Version 7 Version already deleted, skipping Deleting Version 8 Deleted Deleting Version 9 Deleted Deleting Version 10 Deleted Deleting Version 11 Deleted

SQL Template Tag Port of blakeembrey/sql-template-tag for usage in val.town. Usage import { sqlite } from "https://esm.town/v/std/sqlite" import { sql, zip } from "https://esm.town/v/pomdtr/sql" const query = sql`SELECT * FROM books WHERE author = ${author}`; console.log(query.sql) // => "SELECT * FROM books WHERE author = ?" console.log(query.args) // => [author] const res = await sqlite.execute(query) console.table(zip(res)) For advanced usage (ex: nesting queries), refer to the project readme .

View val changes as a diff. Go to /v/username/valname/version to see a diff between that version and the previous one. For example https://saolsen-changes.web.val.run/v/saolsen/tracing/108

Opentelemetry Tracing for Vals! Enables Opentelemetry tracing for vals. Exports two functions, init and traced_handler . init will set up opentelemetry. For how to use it see this example val . By default, traces log to the console but if you set HONEYCOMB_API_KEY it'll also push the traces to honeycomb. In the future we can add more export targets for other services. I'm also thinking about making a val to display them. traced_handler is a wrapper for your handler you can use on an HTTP val. Just pass it your HTTP function and export it as the default and it'll trace every request. Here's a screenshot of what the honeycomb view of a trace from my connect playing val looks like.

Val Town Adapter for lowdb @std/blob is used as a lowdb sync. See @pomdtr/lowdb_example for example usage.

Generates a 3D model of a flat washer, in .stl format. Pass in number parameters for washer "thickness" ("t"), "hole_radius" ("hr"), and "outer_radius" ("r"): https://dupontgu-washer_3d.web.val.run/?t=2&hr=8&r=10

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
