This Ember addon is a simple pagination component which uses Twitter Bootstrap markup. It works with both server-side and client-side pagination.

• Ember.js v3.4 or above
• Ember CLI v2.13 or above
• Node.js v8 or above

ember install ember-simple-pagination

In your templates:

{{simple-pagination
  recordCount=recordCount
  pageSize=pageSize
  pageNumber=pageNumber
  maxPagesInList=maxPagesInList
  dataTestSelector='my-test-selector'
  onPageSelect=(action "getPage")}}

• recordCount: The total number records in the collection being paginated.
• pageSize: The number of records in each page.
• pageNumber: The current page number. Note that page numbers begin at 1, not 0.
• maxPagesInList: The maximum of page numbers to display. Defaults to 10.
• dataTestSelector: adds a data-test-selector attribute to the outer div. Defaults to null.

onPageSelect: This fires when the user clicks a page number link, or the next page or previous page links. It will invoke the external action specified. The page number selected by the user will be passed to the action. The action is not invoked if the user selects the current page link, or the previous page link if the current page === 1, or the next page link if the current page === the total number of pages.

This example assumes the Ember JSONAPIAdapter and on the server JSONAPI::Resources.
