NgxPaginate

Angular pagination component for your grid (or any other form of data). It's just concerned of remembering current page state.

It calculates how many pages it needs/can display for user to select from based on current page, page size and total items.

Usage

npm install ngx-paginate --save

Import module

import { NgxPaginateModule } from 'ngx-paginate';

@NgModule({
  imports: [
    NgxPaginateModule
  ]
})

Use in your component:

<ngx-paginate
  [page]="page"
  [options]="options"
  (pageChange)='setPage($event)'
  (pageSizeChange)='setPage($event)'>
</ngx-paginate>

Where page is of type PageState (comes with component as well):

export class PageState {
  currentPage: number;
  pageSize: number;
  totalItems?: number;
  numberOfPages?: number;
}

Options are type of PaginateOptions (comes with component as well):

export class PaginateOptions {
  // number of how many pages additionally will be shown on left and right
  spanPages: number;
  // show or hide button for first page (default is true)
  firstPage: boolean;
  // show or hide button for previous page (default is true)
  previousPage: boolean;
  // show or hide button for next page (default is true)
  nextPage: boolean;
  // show or hide button for last page (default is true)
  lastPage: boolean;
  // string that will be shown in appropriate boxes (defaults to <<, >>, < and >)
  titles: {
    firstPage: string;
    lastPage: string;
    previousPage: string;
    nextPage: string;
  };
  // which values to allow to change page for
  pageSizes: [{
    value: 5,
    display: '5'
  }, {
    value: 10,
    display: '10'
  }, {
    value: 15,
    display: '15'
  }]
}

Default options are:

const defaults: PaginateOptions = {
  spanPages : 2,
  previousPage: true,
  nextPage: true,
  firstPage: true,
  lastPage: true,
  titles: {
    firstPage: 'First',
    previousPage: 'Previous',
    lastPage: 'Last',
    nextPage: 'Next',
    pageSize: 'Items per page'
  },
  pageSizes: [{
    value: 5,
    display: '5'
  }, {
    value: 10,
    display: '10'
  }, {
    value: 15,
    display: '15'
  }]
};

And pageChange is triggered each time page is changed via component:

pageChange(pageState: PageState) {
  console.log('Page changed. Reload data with new paging values');
  // do whatever you need here
}

Customize colors

To modify how each page entry would look like you need to provide some css overrides in your component (::ng-deep)

.page-entry - each page number entry

and

.page-entry.active - active page entry

For example

ngx-paginate ::ng-deep .page-entry {
  background-color: black;
  color: yellow;
}
ngx-paginate ::ng-deep .page-entry.active {
  background-color: blue;
  color: red;
}
