Reading and Writing Blobs

Val Town comes with blob storage built-in. It allows for storing any data: text, JSON, images

The blob helper can be imported from any val.

import { blob } from "https://esm.town/v/std/blob";

New blobs are created using setJSON.

await blob.setJSON("key", { value: 1 });

setJSON can be used to retrieve a specific blob.

const value = blob.getJSON("key");
console.log(value);

The lower level set and get can be used to store non-JSON or binary data.

const resp = await fetch("https://picsum.photos/600/300");
await blob.set("image", resp.body);
const image = await blob.get("image");
