# lonadb-client

The JavaScript-Client is an npm library designed to facilitate communication with LonaDB's "Hadro" Database Server. This library provides a convenient way to interact with the server's various functions, allowing you to manage tables, variables, users, permissions, and more. It simplifies the process of sending requests and receiving responses from the server using the TCP protocol.

## Installation

You can install the JavaScript-Client library using npm:

```bash
npm install lonadb-client
```

## Usage

To use the `lonadb-client` library, follow these steps:

1. Import the required modules and classes:

```javascript
const LonaClient = require("lonadb-client");
```

2. Create an instance of the `LonadbClient` class:

```javascript
const client = new LonaClient(host, port, name, password);
```

Replace `host`, `port`, `name`, and `password` with the appropriate values for your Hadro Database Server.

3. Use the provided methods to interact with the server:

```javascript
// Example: Get a list of tables
client.get("Table", "Variable name")
    .then(data => {
        console.log("The content of the variable is " + data);
    })
    .catch(error => {
        console.error("Error:", error);
    });
```
