WIDE Store any unstructured JSON data. Retrieve it with an expressive and efficient query system. WIDE is a library and service hosted on Val Town. Authenticate and use it with your Val Town credentials, or fork it and connect it to your own Clickhouse Instance. import { ValSession } from 'https://esm.town/v/maxm/valSession';
import { Wide } from 'https://esm.town/v/maxm/wide';
// Use your Val Town API Token to create a session
const wide = new Wide(await ValSession.new(Deno.env.get("valtown")))
// Write any data.
await wide.write([
{ user: {id: 1, name: 'Alice', email: 'alice@example.com' }},
{ user: {id: 2, name: 'Bob', email: 'bob@example.com' }},
{ user: {id: 3, name: 'Charlie', email: 'charlie@example.com' }},
]);
await wide.fields("user.")
// => [
// { fieldName: "user.email", fieldType: "string", count: 3 },
// { fieldName: "user.id", fieldType: "number", count: 3 },
// { fieldName: "user.name", fieldType: "string", count: 3 }
// ]
await wide.values("user.email")

Val Session import { ValSession } from "https://esm.town/v/maxm/valSession";

const user = await ValSession.validate(token); Fork it, provide your own VT_SESSION_PRIVATE_KEY, and update the hardcoded public key. You can generate your own keys like so: import { crypto } from "https://deno.land/std@0.198.0/crypto/mod.ts";
// Generate a key pair for JWT signing and verification
const { privateKey, publicKey } = await crypto.subtle.generateKey(
