SqlToJs

SqlToJs is a library that allows you to run SQL queries over JavaScript object arrays.

Installation

🎉👏🚀 Thank you for choosing SqlToJs! We hope you find it useful. 💻💪

The library is not published yet, but you can download the source code from the GitHub repository and use it in your project.

To use the library in your project, simply include the ./path-to-index.js-file-of-liberary file in your HTML file:

<script src="./path-to-index.js-file-of-liberary"></script>

Usage

To use the library, you first need to create a JavaScript object array that contains your data. Here's an example:

const users = [
  { id: 1, name: 'John', age: 25 },
  { id: 2, name: 'Mary', age: 30 },
  { id: 3, name: 'Peter', age: 35 },
];

Once you have your data, you can run SQL queries over it using the runSQL() method. Here's an example:

import { runSQL, buildDbEnv } from './path-to-index.js-file-of-liberary';
const tables = [
    { identifier: 'users', table: users }
]
const small_env = buildDbEnv(tables); 
const result = runSQL('SELECT name FROM data WHERE age > 30',small_env);
console.log(result);

This will output:

[
  { name: 'Peter' },
]

Contribution

We welcome contributions to the SqlToJs library. If you find a bug, have a feature request, or want to contribute code, please open an issue or pull request on the GitHub repository.

Make sure you have nodejs installed

run npm run test in the root directory

open __test__ directory create a test file, for now we can start with select.js

import assert from 'assert';
import { products, users } from '../data.js';
import { runSQL, buildDbEnv } from '../index.js';

const tables = [
    { identifier: 'products', table: products.slice(0, 3) },

    { identifier: 'users', table: users.slice(0, 3) }
]
const functions = [];

// to query small set
const small_env = buildDbEnv(tables, functions); 

export default (env) => {
    const debug = true;

    assert.deepEqual(runSQL(`SELECT category From products`, small_env, debug), [
        { category: 'Electronics' },
        { category: 'Electronics' },
        { category: 'Electronics' }
    ]);
    
    // create your test here 
   

}
