• Extracts mountpoint metadata
• Fully typed for TypeScript
• Compatible with Node.js

---

📦 Installation

npm install ntrip-sourcetable-parser

🚀 Usage & Example

import { ntripSourcetableParser } from 'ntrip-sourcetable-parser'

const options = {
  host: 'positionz-rt.linz.govt.nz',
  port: 2101,
}

// Example #1 - Then...Catch
ntripSourcetableParser(options)
  .then((mountpoints) => {
    console.log(mountpoints)
  })
  .catch(console.error)

// Example #2 - Async/Await
async function fetchMountpoints() {
  try {
    const mountpoints = await ntripSourcetableParser(options)
    console.log(mountpoints)
  } catch (error) {
    console.error(error)
  }
}
fetchMountpoints()

// Example #3 - Filtering Results
async function fetchAndFilterMountpoints() {
  try {
    const mountpoints = await ntripSourcetableParser(options)
    const freeMountpoints = mountpoints.filter((mp) => !mp.fee)
    console.log('Free mountpoints:', freeMountpoints)
  } catch (error) {
    console.error('Error fetching or filtering mountpoints:', error)
  }
}
fetchAndFilterMountpoints()

// Example #4 - Graceful Error Handling
async function fetchWithGracefulErrorHandling() {
  try {
    const mountpoints = await ntripSourcetableParser(options)
    console.log('Successfully fetched mountpoints:', mountpoints)
  } catch (error) {
    if (error.message.includes('network')) {
      console.error('Network error occurred. Please check your connection.')
    } else {
      console.error('An unexpected error occurred:', error)
    }
  }
}
fetchWithGracefulErrorHandling()

// Example #5 - Chaining Multiple Async Calls
async function fetchAndProcessMountpoints() {
  try {
    const mountpoints = await ntripSourcetableParser(options)
    const processedMountpoints = mountpoints.map((mp) => ({
      ...mp,
      description: `${mp.mountpoint} (${mp.country})`,
    }))
    console.log('Processed mountpoints:', processedMountpoints)
  } catch (error) {
    console.error('Error processing mountpoints:', error)
  }
}
fetchAndProcessMountpoints()

// Example #6 - Using with Custom Configuration
async function fetchWithCustomConfig() {
  const customOptions = {
    host: 'example-rtk-caster.com',
    port: 8080,
    username: 'user',
    password: 'pass',
    position: { lat: 40.7128, lon: -74.006 },
    version: '2.0',
  }

  try {
    const mountpoints = await ntripSourcetableParser(customOptions)
    console.log('Mountpoints from custom caster:', mountpoints)
  } catch (error) {
    console.error('Error fetching from custom caster:', error)
  }
}
fetchWithCustomConfig()
