To create a simple MeshCentral client for a web application,follow these steps:

1. Install Dependencies:

   npm install meshcentral-api meshcentral-web-gl

2. Initialize the Client:

   const { client } = require('meshcentral-api');
   const meshCentralClient = new client('socket', url, {
       meshUrl: 'http://localhost:88',
       meshConfig: {
           address: 'localhost',
           port: 88,
           user: 'meshcentral',
           password: 'your password'
       }
   });

3. Connect to a Mesh:

   meshCentralClient.mesh('myMesh').connect();

4. Subcribe to the 'meshes' Topic:

   meshCentralClient.mesh('myMesh').subscribe('meshes');

5. Receive and Process Data:

   const { meshData, meshId } = meshCentralClient.mesh('myMesh').subscribe(' meshes ');
   while (true) {
       const data = meshCentralClient.mesh('myMesh').receive();
       if (data.meshId) {
           meshCentralClient.mesh(data.meshId).connect();
           // Handle received data here
       }
   }

6. Handle Network Errors:

   try {
       // Handle successful connection
       console.log('Connected to mesh:', meshCentralClient.mesh(data.meshId).meshId);
   } catch (err) {
       console.error('Connection failed:', err);
   }

This setup provides a basic client for connecting to and managing meshes via MeshCentral. Note that for a production environment, additional security measures, error handling, and state management should be implemented to ensure a secure and robust application.
