## 🚀 Quick Example

Here’s how to get started using **PuddySQL**:

```js
import path from 'path';
import { fileURLToPath } from 'url';
import PuddySql from 'puddysql';

const __filename = fileURLToPath(import.meta.url);
const __dirname = path.dirname(__filename);

// 🎮 Create a new SQL instance
const db = new PuddySql.Instance();

// 📡 Run queries
(async () => {
  await db.initSqlite3();

  // Insert a new user
  const table = await db.initTable({ name: 'tinytest', id: 'id' }, [
      ['id', 'TEXT', 'PRIMARY KEY'],
      ['prompt', 'TEXT'],
      ['yay', 'BOOLEAN']
  ]);

  console.log('Set');
  console.log(await table.set('1', { prompt: 'pudding', yay: true }));
  console.log(await table.set('2', { prompt: 'cookie', yay: true }));
  console.log(await table.set('3', { prompt: 'brigadeiro', yay: true }));
  console.log(await table.set('4', { prompt: 'banana', yay: false }));
  console.log(await table.set('5', { prompt: 'chocolate', yay: true }));

  console.log('Get All');
  console.log(await table.getAll());

  // Find a user by ID
  console.log('Get');
  const user = await table.get(1);
  console.log(user); // → { id: 1, prompt: 'pudding', yay: true }

  // Get a paginated list
  console.log('Search');
  const data1 = await db.getTable('tinytest').search({
      q: {
        group: 'AND',
        conditions: [{ column: 'prompt', value: 'pudding' }],
      },
    });

  const data2 = await table.search({
      q: {
          group: 'OR',
          conditions: [
            { column: 'prompt', value: 'pudding' },
            { column: 'yay', value: false },
          ],
      },
    });

  console.log(data1); 
  console.log(data2); 
})();
```
