Important Things to Consider Before Selecting a Weather App API

There are a few things to take into account while choosing a weather app API for an app:

  1. Accuracy: Check to ensure that the weather information the API gives is exact and reliable. Inaccurate figures could make the clients unhappy and lose confidence in your application.
  2. Coverage: Verify whether the weather app API is available worldwide or only in a few places. The target user base for your app may require weather information for multiple global locations.
  3. Data Frequency: Take into account how often the API refreshes its database. For customers who want current weather information, especially for outdoor activities or travel plans, real-time or frequent updates are essential.
  4. Support and Documentation: Evaluate the degree of assistance offered by the API provider and the caliber of the documentation for the API. While responsive help can assist with settling any issues that might emerge during development, well-written documentation facilitates API integration into your application.
  5. Historical Data: Certain apps might need access to previous weather data for analytical or research purposes. Check the length of the accessible history records and whether the weather app API provides historical weather data.
  6. Pricing and Limitations for APIs: Examine the API’s cost structure and any usage constraints, such as minute-by-minute requests or restrictions on data access. Make sure the API’s cost fits your application’s spending plan and usage needs.
  7. Dependability and Uptime: Select an API that has a track record of dependability and little downtime. The usability and functionality of your app may be negatively impacted by unreliable APIs.
  8. Data Security and Privacy: Ensure that the API provider complies with data security and privacy regulations, especially if your app collects user location data for personalized weather forecasts.

How to connect to RESTful web services in Delphi?

REST Debugger is a powerful environment to play with RESTful web services. You can start REST Debugger from the Tools menu of the IDE.

Here is how we can establish a connection:

connecting to RESTful web services in Delphi using rest debugger

And after successfully connecting to the RESTful web service, we can just copy configured REST Client components by clicking the Copy components button and paste them into our project.

Here is our application user interface structure:

application interface of a weather app api showing the weather conditions of new york

The user interface is responsive and flexible. I have tried to utilize best practices in UI design. 

Now, you need to paste the copied components from the REST Debugger and create an OnClick event on the Search button.

And paste this code to the OnClick event.

As you can see, we are reconfiguring the request URL based on the input by the user.

Then we are parsing JSON and opening the current object. The current object has the main weather data, for instance: temperature, humidity, weather icon, and more.

After that, we are getting the first element from the weather description array which holds a summary of the weather info.

Then we are parsing the weather icon and downloading the image and setting it to the TImage component.

I hope everything in this code is clear. I am pretty sure you can learn so much about JSON manipulation in Delphi and creating cross-platform applications with Delphi FireMonkey.
