T-POI-DIRECTIONS: Add Directions To Poi Popup And List

by ADMIN 55 views

Introduction

In today's digital age, providing users with accurate and convenient information is crucial for any navigation system. One of the key features that can enhance user experience is the ability to get directions from a point of interest (POI). In this article, we will explore how to add directions to POI popup and list, making it easier for users to navigate to their desired destination.

Description

The goal of this feature is to provide users with a seamless experience when getting directions from a POI. This can be achieved by integrating a "Get Directions" button in the POI popup and list, allowing users to easily access turn-by-turn directions to their desired location.

Requirements

To implement this feature, we need to meet the following requirements:

Get Directions from a POI Popup

  • Given the user clicks the "Get Directions" button in the POI popup.
  • Then the user's current location is set as the starting point.
  • And the selected POI is set as the destination.

Get Directions from a POI in List

  • Given the user clicks the "Get Directions" button next to a POI in the list.
  • Then the selected POI is set as the destination.

Technical Implementation

To add directions to the POI popup and list, we will need to integrate a mapping library such as Google Maps or OpenStreetMap. We will also need to create a backend API to handle the request and return the directions.

Step 1: Set up the Mapping Library

First, we need to set up the mapping library and create a map instance. We will use the Google Maps API for this example.

const map = new google.maps.Map(document.getElementById('map'), {
  center: { lat: 37.7749, lng: -122.4194 },
  zoom: 12,
});

Step 2: Create the POI Popup and List

Next, we need to create the POI popup and list. We will use HTML and CSS to style the popup and list.

<!-- POI Popup -->
<div id="poi-popup" class="poi-popup">
  <h2>POI Name</h2>
  <p>POI Description</p>
  <button id="get-directions-btn">Get Directions</button>
</div>

<!-- POI List -->
<ul id="poi-list" class="poi-list">
  <li>
    <h2>POI 1</h2>
    <p>POI 1 Description</p>
    <button class="get-directions-btn">Get Directions</button>
  </li>
  <li>
    <h2>POI 2</h2>
    <p>POI 2 Description</p>
    <button class="get-directions-btn">Get Directions</button>
  </li>
</ul>

Step 3: Add Event Listeners

We need to add event listeners to the "Get Directions" button in the POI popup and list. When the button is clicked, we will call the backend API to get the directions.

document.getElementById('get-directions-btn').addEventListener('click', () => {
  const poiName = document.querySelector('.poi-popup h2').textContent;
  const poiDescription = document.querySelector('.poi-popup p').textContent;
  const userLocation = { lat: 37.7749, lng: -122.4194 };
  const poiLocation = { lat: 37.7859, lng: -122.4364 };

  // Call backend API to get directions
  fetch('/get-directions', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      poiName,
      poiDescription,
      userLocation,
      poiLocation,
    }),
  })
    .then((response) => response.json())
    .then((data) => {
      console.log(data);
      // Display directions on the map
      const directions = data.directions;
      const route = new google.maps.DirectionsRenderer({
        map: map,
        directions: directions,
      });
    })
    .catch((error) => console.error(error));
});

// Add event listener to POI list
document.querySelectorAll('.get-directions-btn').forEach((btn) => {
  btn.addEventListener('click', (e) => {
    const poiName = e.target.parentNode.querySelector('h2').textContent;
    const poiDescription = e.target.parentNode.querySelector('p').textContent;
    const userLocation = { lat: 37.7749, lng: -122.4194 };
    const poiLocation = { lat: 37.7859, lng: -122.4364 };

    // Call backend API to get directions
    fetch('/get-directions', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({
        poiName,
        poiDescription,
        userLocation,
        poiLocation,
      }),
    })
      .then((response) => response.json())
      .then((data) => {
        console.log(data);
        // Display directions on the map
        const directions = data.directions;
        const route = new google.maps.DirectionsRenderer({
          map: map,
          directions: directions,
        });
      })
      .catch((error) => console.error(error));
  });
});

Conclusion

In this article, we explored how to add directions to the POI popup and list, making it easier for users to navigate to their desired destination. We implemented the feature using the Google Maps API and created a backend API to handle the request and return the directions. By following these steps, you can enhance the user experience of your navigation system and provide users with a seamless experience when getting directions from a POI.

Future Development

In the future, we can improve this feature by adding more features such as:

  • Real-time traffic updates: We can integrate real-time traffic updates to provide users with the most up-to-date information.
  • Alternate routes: We can provide users with alternate routes in case of traffic congestion or road closures.
  • POI filtering: We can add a filtering feature to allow users to filter POIs by category, rating, or distance.

By continuously improving and enhancing the user experience, we can make our navigation system more user-friendly and efficient.
