Using ngFor to Filter Tables in Angular 5

Are you in the midst of implementing multiple data filters in an Angular Application that displays data using a Table and ngFor? You may have explored different methods such as using Pipe in Type Script, but discovered that it is not recommended according to Angular documentation. If this is the case, what would be the most suitable approach for integrating Multiple Filters in Angular? Eager to learn about potential Solutions...

Answer №1

Avoid using pipes in ngFor loops as it can significantly impact performance and efficiency. Instead, consider moving sorting and filtering logic into the component itself to improve overall functionality and speed.

Creating custom pipes for specific tasks is a better alternative, and there are plenty of resources available online to guide you through the process. The Angular team also provides valuable insights on this topic here.

Remember, while built-in pipes like date formatting are still efficient, sorting and filtering operations can be resource-intensive if handled with pipes. Take the advice of experienced developers and aim for optimized performance by implementing logic within the component.

Answer №2

To establish your filter, create a QueryArray where each element includes a field, operator, and value. Then, within a loop, add or update each element in the QueryArray accordingly.
