Jelly SQL - CSS Query Selectors With SQL

About

Query the DOM in JavaScript with a familiar SQL syntax. Generates a CSS query selector that will in turn call the document.querySelectorAll().

Getting Started

Jelly SQL requires no third-party dependencies. You can use it in the browser or in Node.js. TypeScript is also supported.

Full documentation can be found at docs.jellysql.com.

Using npm or yarn

Install

npm install jelly-sql

OR

yarn add jelly-sql

Import & Use

See the API documentation for more information, and the cheat sheet for a quick reference.

import { query } from 'jelly-sql';

const selector = query(`SELECT * FROM DOM WHERE TAG = 'a'`);
console.log(selector); // Output: "a"

Using a CDN (Browser)

You can also use Jelly SQL in the browser by including the following script tag:

<script src="https://cdn.jsdelivr.net/npm/jelly-sql@latest/build/dist/jelly-sql.min.js"></script>

Usage

This will expose the jellySQL object globally, which you can use to query the DOM. See the API documentation for more information, and the cheat sheet for a quick reference.

const selector = jellySQL.query(`SELECT * FROM DOM WHERE TAG = 'a'`);
console.log(selector); // Output: "a"
