Service Type Lookup

This feature allows you to look up details about a specific service type by its name. The code sample demonstrates how to retrieve information about the 'http' service type, including its protocol and description.

const serviceTypes = require('multicast-dns-service-types');

// Lookup a service type by name
const serviceType = serviceTypes['http'];
console.log(serviceType); // Output: { name: 'http', protocol: 'tcp', description: 'Web Site' }

List All Service Types

This feature allows you to list all available service types along with their details. The code sample iterates over all service types and prints their names and corresponding details.

const serviceTypes = require('multicast-dns-service-types');

// List all service types
for (const [key, value] of Object.entries(serviceTypes)) {
  console.log(`${key}: ${JSON.stringify(value)}`);
}
