  console.log(`Received message: ${event.data}`);
};

socket.onopen = () => {
  console.log('Connected to the WebSocket server');
};

socket.onerror = (event) => {
  console.log('Error occurred while connecting to the WebSocket server');
};

socket.onclose = () => {
  console.log('Disconnected from the WebSocket server');
};

When implementing real-time messaging, consider low latency data delivery, message delivery guarantees, scalability, elasticity, and reliability to ensure a seamless communication experience.

Group Chats and Channels

Group chats and channels allow team members to communicate in groups and organize conversations by topic or project. To set up these features, create a data model for channels and group chats, and implement functionality to create, manage, and delete them. Here's an example of creating a channel using Node.js:

const express = require('express');
const app = express();

app.post('/channels', (req, res) => {
  const channelName = req.body.channelName;
  const channelDescription = req.body.channelDescription;

  // Create a new channel in the database
  db.query(`INSERT INTO channels (name, description) VALUES (?,?)`, [channelName, channelDescription], (err, results) => {
    if (err) {
      res.status(500).send({ error: 'Failed to create channel' });
    } else {
      res.send({ message: `Channel created successfully` });
    }
  });
});

When implementing group chats and channels, consider features like channel creation, management, deletion, user permissions, and access control.

File Sharing

File sharing allows team members to share files, which is useful for collaborative projects. To integrate file sharing, you can use a cloud storage service like AWS S3 or Google Cloud Storage. Here's an example of uploading a file to AWS S3 using Node.js:

const s3 = new AWS.S3({
  accessKeyId: 'YOUR_ACCESS_KEY_ID',
  secretAccessKey: 'YOUR_SECRET_ACCESS_KEY',
  region: 'YOUR_REGION'
});

const fileBuffer = fs.readFileSync('example.txt');
const params = {
  Bucket: 'YOUR_BUCKET_NAME',
  Key: 'example.txt',
  Body: fileBuffer
};

s3.upload(params, (err, data) => {
  if (err) {
    console.log(err);
  } else {
    console.log(`File uploaded successfully: ${data.Location}`);
  }
});

When implementing file sharing, consider features like file upload, download, management, security, and access control.

axios.get('https://api.github.com/repos/octocat/hello-world/issues', {
  headers: {
    'Authorization': 'Bearer YOUR_GITHUB_TOKEN'
  }
})
.then(response => {
  console.log(response.data);
})
.catch(error => {
  console.log(error);
});

When implementing tool integrations, consider features like API connectivity, data synchronization, and user authentication.

Search and Archive

Search and archive features allow team members to easily find specific conversations or files. To implement these features, you can use a search engine like Elasticsearch or Algolia. Here's an example of creating an Elasticsearch index using Node.js:

  host: 'YOUR_ELASTICSEARCH_HOST',
  apiVersion: '7.10'
});

client.indices.create({
  index: 'my_index'
})
.then(response => {
  console.log(response);
})
.catch(error => {
  console.log(error);
});
