Efficiently Sorting Data in Angular 8

Sorting data according to user preferences can be a common requirement in web applications. In Angular 8, particularly when using dropdowns to let users select the field to sort by and the order of sorting, it’s essential to implement this efficiently. In this guide, we will walk through how to achieve this by creating a clean and maintainable sorting solution that utilizes custom functions rather than cumbersome conditional logic.

The Problem: Complex Sorting Logic

Imagine you have two dropdowns in your Angular application where users can pick how they'd like to sort a dataset. For example, one dropdown allows selection of a "Sort By" field (like SKU or Planned), while the other controls the order of that sort (A-Z or Z-A). The initial implementation might look straightforward, yet it can quickly become cluttered with multiple if...else statements to manage various combinations of user selections. This can lead to code that is hard to read and maintain.

An Example Scenario

You might start with HTML resembling this:

And your sorting function may look something like this:

Handling various combinations of sorting requires a complex function, which leads to redundancy and unnecessarily complicated code.

The Solution: Implementing a Custom Sort Function

To streamline the sorting process and improve code readability, we can implement a custom sort function. This function will encapsulate the logic needed to sort by different fields while maintaining the required order.

Step 1: Creating a Custom Sort Function

Here’s a simple implementation of a sorting function that can handle both string and numeric comparisons:

This function checks if the field value is a string or a number and sorts accordingly.

Step 2: Integrating the Custom Function into Your Sort Logic

Now let’s modify our sortData function to leverage the newly created custom sort function:

In this streamlined approach, you’ve avoided redundancy and improved the maintainability of your code. The sorting mechanism is now neatly encapsulated in a standalone function, making your code base cleaner and much easier to understand.

Conclusion

By implementing a custom sort function, you can reduce the complexity of your sorting logic in Angular 8 applications significantly. Not only does this approach improve code clarity, but it also enhances the overall performance of your application by reducing the amount of repeated logic.

Feel free to adopt this method in your next Angular project to make sorting data more efficient. Happy coding!
