How can we incorporate a custom filter pipe and pagination in Angular 2?

I've developed a component that showcases a paginated, sortable, and filterable table of dates. While I have successfully implemented a custom pagination service to display the data in parts, my issue lies with the functionality of the filter and sort pipes. Currently, these pipes only work for the sliced data rather than the complete JSON dataset. I would greatly appreciate any suggestions on how to parse the full data set effectively. Below is an example of how I am currently using the filter pipe and sort pipe:

<tbody *ngFor = "let request of slicedRequestObjects | category: searchText : optionVal | orderBy: convertSorting(); let i = index;" >

Answer №1

Ensuring the correct sequence of filtering and pagination is crucial for optimal functionality. If you have a list of 50 items, make sure that your filter is applied before the pagination kicks in. Otherwise, it may seem like only the first set of filtered results are being paginated.

I personally rely on a module called ng2-pagination for this task. This module acts as a pipe within the *ngFor directive. Additionally, I have developed a custom pipe to handle the filtering process seamlessly.

The implementation typically resembles something along the lines of:

*ngFor="let item of myList | termFilter:searchTerm | paginate: { itemsPerPage: 15, currentPage: c, id: 'c' }"
