```

## 🛠️ Using ZeroHelper for helper functions

# Random Functions 🎲

```js
const helpers = require("@onurege3467/zerohelper/functions");

const id = helpers.random.makeUniqueId();
console.log(id); // Example: "lzx8k9x8k9"

const item = helpers.random.randomArray([1, 2, 3, 4, 5]);
console.log(item); // Example: 3

const text = helpers.random.randomText(10);
console.log(text); // Example: "aBcDeFgHiJ"

const number = helpers.random.randomNumber(1, 100);
console.log(number); // Example: 42

const emoji = helpers.random.randomEmoji();
console.log(emoji); // Example: "😄"

const hex = helpers.random.randomHex();
console.log(hex); // Example: "#A1B2C3"

console.log(float); // Example: 3.14
```

# String Functions 🔠

```js
const title = helpers.string.titleCase("hello world");
console.log(title); // "Hello World"

const randomString = helpers.string.generateRandomString(8);
console.log(randomString); // Example: "AbCdEfGh"

console.log(shuffled); // Example: [3, 1, 5, 4, 2]

const flat = helpers.array.flattenArray([1, [2, [3, 4]], 5]);
console.log(flat); // [1, 2, 3, 4, 5]

const filtered = helpers.array.removeFalsyValues([0, 1, false, 2, "", 3]);
console.log(filtered); // [1, 2, 3]

const grouped = helpers.array.groupBy(
  [
    { category: "fruit", name: "apple" },
    { category: "fruit", name: "banana" },
    { category: "vegetable", name: "carrot" },
  ],
  "category"
);
console.log(grouped);
// {
//   fruit: [{ category: "fruit", name: "apple" }, { category: "fruit", name: "banana" }],
//   vegetable: [{ category: "vegetable", name: "carrot" }]
// }

const names = helpers.array.pluck(
  [{ name: "Alice" }, { name: "Bob" }, { name: "Charlie" }],
  "name"

  await db.close();
})();
```
## Schema DB

```javascript
const path = require('path');
const createDatabase = require('@onurege3467/zerohelper/database'); // Adjust the path to your project structure

// --- 1. Using SQLite (Fast and Lightweight) ---
const sqliteDb = createDatabase({
  adapter: 'sqlite',
  config: {
    filePath: path.join(__dirname, 'data', 'development.sqlite')
  }
});

// --- 2. Using MySQL (For Production) ---
const mysqlDb = createDatabase({
  adapter: 'mysql',
  config: {
    host: 'localhost',
    user: 'root',
    password: 'your_password',
    database: 'my_app_prod'
  }
});

// --- 3. Using a JSON File (For Simple Prototyping) ---
const jsonDb = createDatabase({
  adapter: 'json',
  config: {
    filePath: path.join(__dirname, 'data', 'db.json')
  }
});

// --- 4. Using MongoDB ---
const mongoDb = createDatabase({
    adapter: 'mongodb',
    config: {
        url: 'mongodb://localhost:27017',
        database: 'my_app_mongo'
    }
});
```

### Basic Operations (CRUD)

No matter which adapter you choose, you can use the following methods in exactly the same way.

```javascript
async function main() {
  // Let's use sqliteDb for this example
  const db = createDatabase({
    adapter: 'sqlite',
    config: { filePath: 'app.db' }
  });

  try {
    // Insert Data
    const newUserId = await db.insert('users', { name: 'John Doe', email: 'john@example.com', age: 30 });
    console.log(`New user added with ID: ${newUserId}`);

    // Select Data
    const user = await db.selectOne('users', { name: 'John Doe' });
    console.log('Found user:', user);

    // Update Data
    await db.update('users', { age: 31 }, { email: 'john@example.com' });
    console.log('User updated.');

    // Update if exists, or insert if not (Upsert)
    await db.set('users', { city: 'New York' }, { name: 'John Doe' }); // Updates existing
    await db.set('users', { name: 'Jane Doe', email: 'jane@example.com' }, { name: 'Jane Doe' }); // Inserts new

    // Select All Data
    const allUsers = await db.select('users');
    console.log('All users:', allUsers);

    // Delete Data
    await db.delete('users', { name: 'John Doe' });
    console.log('User deleted.');

  } catch (error) {
    console.error('An error occurred:', error);
  } finally {
    // Close the connection
    await db.close();
  }
}

main();
```

### 📚 API Reference

All adapters implement the following common methods (the `IDatabase` interface):

- `select(table, where)`: Returns an array of all rows matching the query.
- `selectOne(table, where)`: Returns the first row matching the query as an object, or `null`.
- `insert(table, data)`: Inserts a new row and returns its ID.
- `update(table, data, where)`: Updates rows matching the query and returns the number of affected rows.
- `delete(table, where)`: Deletes rows matching the query and returns the number of affected rows.
- `set(table, data, where)`: Updates a record if it exists, otherwise inserts it as a new record.
- `bulkInsert(table, dataArray)`: Inserts an array of objects in a single, optimized operation.
- `close()`: Safely closes the database connection or file handle.

## Database Migration

The `migrateData` function allows you to migrate data between different types of databases. It supports JSON, MongoDB, MySQL, SQLite, Redis, and PostgreSQL.

# Example: Migrate Data from JSON to MongoDB

```js
const migrateData = require("@onurege3467/zerohelper/database/migrate");

const sourceConfig = {
  type: "json",
  options: {
    filePath: "databases/source.json", // Path to the JSON file
  },
};

const targetConfig = {
  type: "mongodb",
  options: {
    url: "mongodb://localhost:27017", // MongoDB connection URL
    database: "targetDatabase", // Target database name
    collection: "targetCollection", // Target collection name
  },
};

(async () => {
  try {
    await migrateData(sourceConfig, targetConfig);
    console.log("Data migration completed successfully!");
  } catch (error) {
    console.error("Error during migration:", error);
  }
})();
```
