Building an Istanbul Travel Planner App

Let’s put all these APIs together and build a simple travel planner app that will help you have a seamless experience while exploring Istanbul.

Step 1: Set up the Project

 mkdir istanbul-travel-planner cd istanbul-travel-planner npm init -y npm install express axios 

Step 2: Create the Server

 const express = require('express'); const axios = require('axios');
const app = express(); const port = 3000;
app.get('/weather', async (req, res) => {
  try {
    const response = await axios.get('https://api.istanbulweather.com/v1/current?city=istanbul', {
      headers: {'content-type': 'application/json', 'API Key': 'YourAPIKeyHere'}
    });
    res.json(response.data);
  } catch (error) {
    res.status(500).send(error.message);
  }
});
app.get('/transport', async (req, res) => {
  try {
    const response = await axios.get('https://api.istanbultransport.com/v1/routes?mode=metro', {
      headers: {'content-type': 'application/json', 'API Key': 'YourAPIKeyHere'}
    });
    res.json(response.data);
  } catch (error) {
    res.status(500).send(error.message);
  }
});
app.get('/attractions', async (req, res) => {
  try {
    const response = await axios.get('https://api.istanbulattractions.com/v1/top?city=istanbul', {
      headers: {'content-type': 'application/json', 'API Key': 'YourAPIKeyHere'}
    });
    res.json(response.data);
  } catch (error) {
    res.status(500).send(error.message);
  }
});
app.listen(port, () => {
  console.log(`Istanbul Travel Planner app listening at http://localhost:${port}`);
}); 

Step 3: Run the App

 node index.js 

Now, open your browser and navigate to http://localhost:3000/weather to check the weather, http://localhost:3000/transport for public transport information, and http://localhost:3000/attractions for top attractions.

This travel planner app will ensure you have all the information needed at your fingertips for a memorable experience in Istanbul.
