Overview:

The article discusses the creation of a frontend part of a program for searching data about countries. It provides instructions on how to make an HTTP request to a public API and retrieve a list of countries based on a search criteria. The article also covers filtering the response data to only include specific properties and implementing a debounce technique to improve the user experience. Finally, it explains how to display the search results and country details in the user interface.

Features:

• HTTP Request: The program uses the Rest Countries v2 public API to make an HTTP request and retrieve a list of countries based on a search criteria.
• Response Filtering: The backend response includes various properties of a country, but only a few specific properties are needed. The article explains how to filter the response data to include only the necessary properties.
• Debounce Technique: To improve performance and prevent excessive HTTP requests, the article suggests implementing a debounce technique. This delays the search request by 300ms after the user stops typing, reducing the number of unnecessary requests.
• Input Sanitization: The user input is sanitized using the trim() method to remove leading and trailing spaces. This ensures that the search function works properly even if the input only consists of spaces.
• User Interface: The article explains how to display the search results and country details in the user interface. It suggests using a library called Notiflix for showing alerts and provides an example of showing a message when too many matches are found.
