jql - JSON Query Language - is a fast and simple command-line tool to manipulate JSON data.

Usage: jql [OPTIONS] [QUERY] [OPTIONAL_FILE]

What it is

jql selects and filters JSON with selectors such as "key", [0], ranges and |> pipes, aiming for something simpler to type than jq for everyday lookups.

javascript

import { createNano } from "@userland-run/nano-sdk";

const nano = await createNano({ image: { wasm: "/nano/console.wasm" }, ramMB: 512 });
