# @push.rocks/smartdata
do more with data

## Install
To install `@push.rocks/smartdata`, use npm:

```bash
npm install @push.rocks/smartdata --save
```

This will add `@push.rocks/smartdata` to your project's dependencies.

## Usage
`@push.rocks/smartdata` enables efficient data handling and operation management with a focus on using MongoDB. It leverages TypeScript for strong typing and ESM syntax for modern JavaScript usage. Below are various scenarios demonstrating how to utilize this package effectively in a project.

### Setting Up and Connecting to the Database
Before interacting with the database, you need to set up and establish a connection. This is done by creating an instance of `SmartdataDb` and calling its `init` method with your MongoDB connection details.

```typescript
import { SmartdataDb } from '@push.rocks/smartdata';

// Create a new instance of SmartdataDb with MongoDB connection details
const db = new SmartdataDb({
  mongoDbUrl: 'mongodb://localhost:27017',
  mongoDbName: 'your-database-name',
  mongoDbUser: 'your-username',
  mongoDbPass: 'your-password',
});

// Initialize and connect to the database
await db.init();
```

### Defining Data Models
Data models in `@push.rocks/smartdata` are classes that represent collections and documents in your MongoDB database. Use decorators such as `@Collection`, `@unI`, and `@svDb` to define your data models.

```typescript
import { SmartDataDbDoc, Collection, unI, svDb } from '@push.rocks/smartdata';

@Collection(() => db)  // Associate this model with the database instance
class User extends SmartDataDbDoc<User, User> {
  @unI()
  public id: string = 'unique-user-id'; // Mark 'id' as a unique index
  
  @svDb()
  public username: string;  // Mark 'username' to be saved in DB
  
  @svDb()
  public email: string;  // Mark 'email' to be saved in DB
  
  constructor(username: string, email: string) {
    super();
    this.username = username;
    this.email = email;
  }
}
```

### Performing CRUD Operations
`@push.rocks/smartdata` simplifies CRUD operations with intuitive methods on model instances.

#### Create
```typescript
const newUser = new User('myUsername', 'myEmail@example.com');
await newUser.save();  // Save the new user to the database
```

#### Read
```typescript
// Fetch a single user by a unique attribute
const user = await User.getInstance({ username: 'myUsername' });

// Fetch multiple users that match criteria
const users = await User.getInstances({ email: 'myEmail@example.com' });
```

#### Update
```typescript
// Assuming 'user' is an instance of User
user.email = 'newEmail@example.com';
await user.save();  // Update the user in the database
```

#### Delete
```typescript
// Assuming 'user' is an instance of User
await user.delete();  // Delete the user from the database
```

### Advanced Usage
`@push.rocks/smartdata` also supports advanced features like watching for real-time changes in the database, handling distributed data coordination, and more. These features utilize MongoDB's capabilities to provide real-time data syncing and distributed systems coordination.

### Conclusion
With its focus on TypeScript, modern JavaScript syntax, and leveraging MongoDB's features, `@push.rocks/smartdata` offers a powerful toolkit for data handling and operations management in Node.js applications. Its design for ease of use, coupled with advanced features, makes it a versatile choice for developers looking to build efficient and scalable data-driven applications.
