Data source and retrieval

You need to decide on the data source for your auto-suggestion feature, such as an API or a local data store. You will need to implement the logic to retrieve data from the chosen data source based on user input.

Debouncing or throttling

To optimize performance and prevent unnecessary API calls, you may need to implement debouncing or throttling techniques. Debouncing delays the invocation of a function until a certain amount of time has passed since the last time it was called, while throttling limits the number of times a function can be called within a specific time frame.

Filtering and sorting

Once data is retrieved, you will need to implement logic to filter and sort the data based on user input. This could involve techniques such as string matching, regular expressions, or other custom logic depending on your specific use case.

Rendering and display

You will need to decide on how to render and display the auto-suggestion results to the user. This could be through a dropdown menu, a list, or any other UI component that meets your design requirements.

User interactions

You will need to handle user interactions such as selecting a suggestion, navigating through suggestions, and triggering actions based on user selections. This could involve event handling, state management, and UI updates.

Accessibility

It's important to consider accessibility best practices when designing an auto-suggestion feature, such as providing keyboard navigation, proper focus management, and ensuring that the suggestions are accessible to users with disabilities.

Performance optimization

Depending on the amount of data and the complexity of the filtering and sorting logic, performance optimization techniques may be needed to ensure smooth and efficient auto- suggestion functionality. This could involve memoization, virtualization, or other performance optimization techniques.

Error handling

You will need to handle error scenarios, such as when data retrieval fails or when there are no suggestions available, and provide appropriate error messages or fallbacks to gracefully handle such situations.
