About this template

An app for asking questions about location data based on latitude and longitude coordinates.

Introduction to the Geolocation Address Finder Template

Welcome to the step-by-step guide on how to use the Geolocation Address Finder template on Lazy. This template allows you to create an application that can find addresses based on latitude and longitude coordinates and answer questions related to the location. It's a powerful tool for builders who want to integrate geolocation features into their software without delving into the complexities of coding from scratch.

Getting Started

To begin using this template:

  • Click Start with this Template on the Lazy platform.

Test: Deploying the App

Once you have initiated the template:

  • Press the Test button to start the deployment of your app.

The Lazy CLI will handle the deployment process, and you will not need to install any libraries or set up your environment manually.

Using the App

After the deployment is complete, Lazy will provide you with a dedicated server link. This link allows you to interact with your newly created Geolocation Address Finder app. Additionally, since the app is built using FastAPI, Lazy will also provide a link to the FastAPI documentation, which you can use to explore the API endpoints and their functionalities.

To use the app's interface:

  • Open the provided server link in your web browser to view the HTML form.
  • Enter the latitude and longitude coordinates in the respective fields.
  • Type in your question related to the location in the 'Your Question' field.
  • Click the 'Get Address and Answer' button to submit the form.
  • The app will display the address information and the answer to your question below the form.

Integrating the App

If you wish to integrate this app into an external service or frontend, you can use the server link provided by Lazy. For example, you can make POST requests to the '/get_location' and '/get_answer' endpoints from your external service to fetch location data and get answers to location-based questions.

Here is a sample POST request to the '/get_location' endpoint:

POST /get_location HTTP/1.1<br>
Host: [Your Server Link]<br>
Content-Type: application/x-www-form-urlencoded<br>

Sample response:

  "nearest": {...},<br>
  "locality": {...},<br>
  "adminCode2": "061",<br>

And here is a sample POST request to the '/get_answer' endpoint:

POST /get_answer HTTP/1.1<br>
Host: [Your Server Link]<br>
Content-Type: application/x-www-form-urlencoded<br>
question=What is the name of the city at these coordinates?&locationData={"lat":"40.712776","lon":"-74.005974","city":"New York","country":"USA"}

Sample response:

  "message": "The city at the coordinates 40.712776, -74.005974 is New York."<br>

Remember to replace '[Your Server Link]' with the actual server link provided by Lazy.

By following these steps, you can successfully deploy and integrate the Geolocation Address Finder app into your software solutions using the Lazy platform.
