It allows for storing any data: text, JSON, images. You can access it via [\\`std/blob\\`](https://www.val.town/v/std/blob).\n \n 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.\n \n You may find [this admin viewer](https://www.val.town/v/stevekrouse/blob_admin) helpful for viewing and editing your blobs.\n \n ##### Get JSON\n \n \\`\\`\\`ts title=\"Get JSON\"\n import { blob } from \"https://esm.town/v/std/blob\";\n \n let blobDemo = await blob.getJSON(\"myKey\");\n console.log(blobDemo); // returns \\`undefined\\` if not found\n \\`\\`\\`\n \n ##### Set JSON\n \n \\`\\`\\`ts title=\"Set JSON\"\n import { blob } from \"https://esm.town/v/std/blob\";\n \n await blob.setJSON(\"myKey\", { hello: \"world\" });\n \\`\\`\\`\n \n ##### List keys\n \n \\`\\`\\`ts title=\"List Keys\"\n import { blob } from \"https://esm.town/v/std/blob\";\n \n let allKeys = await blob.list();\n console.log(allKeys);\n \n const appKeys = await blob.list(\"app_\");\n console.log(appKeys); // all keys that begin with \\`app_\\`\n \\`\\`\\`\n \n ##### Delete by key\n \n \\`\\`\\`ts title=\"Delete\"\n import { blob } from \"https://esm.town/v/std/blob\";\n \n await blob.delete(\"myKey\");\n \\`\\`\\`\n \n ### Examples\n \n - [Counter](https://www.val.town/v/std/docsBlobCounterDemo)\n - [RSS Notifications](https://www.val.town/v/stevekrouse/rssNotifyExample) (saving the last run time)\n - Picture: [Save](https://www.val.town/v/andreterron/blobSavePictureExample) & [Read](https://www.val.town/v/andreterron/blobReadPictureExample)\n \n ### Error Handling\n \n - \\`blob.get\\` can throw [\\`ValTownBlobNotFoundError\\`](https://val.town/v/std/ValTownBlobNotFoundError)\n - Any method can throw [\\`ValTownBlobError\\`](https://val.town/v/andreterron/ValTownBlobError) for unexpected errors.\n \n ### Utilities\n \n Our Blob SDK also includes some utility functions to make working with blobs easier.\n \n ##### Copy\n \n \\`\\`\\`ts title=\"Copy\"\n import { blob } from \"https://esm.town/v/std/blob\";\n \n await blob.copy(\"myKey\", \"myKeyCopy\");\n \\`\\`\\`\n \n ##### Move\n \n \\`\\`\\`ts title=\"Move\"\n import { blob } from \"https://esm.town/v/std/blob\";\n \n await blob.move(\"myKey\", \"myKeyNew\");\n \\`\\`\\`\n \n ### Lower-level API\n \n We do 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.\n \n - \\`async get(key: string)\\`: Retrieves a blob for a given key.\n - \\`async set(key: string, value: string | BodyInit)\\`: Sets the blob value for a given key. See [BodyInit](https://deno.land/api@v1.38.1?s=BodyInit).\n \n ### Limitations\n \n - Blob-stored data counts towards your total Val Town storage – 10mb on the free plan and 1gb on pro. Check our [pricing page](https://val.town/pricing) to learn more.\n - Keys for blobs can be up to 512 characters long.\n `,\n },\n {\n role: \"user\",\n content: \"Write an HTTP val that responds to requests with \\\"Hello world\\\"\",\n },\n {\n role: \"assistant\",\n content:\n \"\\n```ts\\nexport default async function (req: Request): Promise {\\n return Response.json(\\\"Hello world\\\")\\n}\\n```\",\n },\n {\n role: \"user\",\n content: \"Write a val that responds to requests with HTML and reads a 'name' from a query string value:\",\n },\n {\n role: \"assistant\",\n content:\n \"\\n```ts\\nexport default async function(req: Request): Promise {\\n const query = new URL(req.url).searchParams;\\n\\n // Read name from the querystring or body.
