ember-cli-jsonapi-pagination

An addon adding support for pagination with JSONAPI backend.

Currently only a paged-based strategy is supported, more details about JSONAPI pagination: http://jsonapi.org/format/#fetching-pagination.

Usage

To install the addon, run:

ember install ember-cli-jsonapi-pagination

You need to include pagination mixins in your route and controller which are responsible for paginated resource:

// app/routes/models/index.js

import Ember from 'ember';
import Pagination from 'ember-cli-jsonapi-pagination/mixins/routes/jsonapi-pagination';

export default Ember.Route.extend(Pagination);

// app/controllers/models/index.js

import Ember from 'ember';
import Pagination from 'ember-cli-jsonapi-pagination/mixins/controllers/jsonapi-pagination';

export default Ember.Controller.extend(Pagination);

That way the query params (size - by default equal to 15 and number - by default equal to 1) and required actions (setCurrentPage for setting current page in query params and setCurrentSize for setting size in query params) are available in the controller / route. To to perform query with pagination params use queryPaginated function which takes model name and params as arguments:

// app/routes/models/index.js
import Ember from 'ember';
import Pagination from 'ember-cli-jsonapi-pagination/mixins/routes/jsonapi-pagination';

export default Ember.Route.extend(Pagination, {
  model(params) {
    return this.queryPaginated('rental', params);
  }
});

You also need to define a property that will return the amount of all pages, this value will most likely come from the meta data in API response, here's one example:

// app/controllers/models/index.js

import Ember from 'ember';
import Pagination from 'ember-cli-jsonapi-pagination/mixins/controllers/jsonapi-pagination';

export default Ember.Controller.extend(Pagination, {
  totalPages: Ember.computed('size', 'number', 'model.[]', function() {
    return this.get('model.meta.total-pages');
  })
});

To render the paginator in your templates, use paginate-collection component:

// app/templates/some-template.hbs

{{paginate-collection totalPages=totalPages currentPage=number setCurrentPage=(action "setCurrentPage")}}

totalPages should be total amount of pages (returned most likely in the meta data in API response), number query param comes from the controller and setCurrentPage also comes from controller.

That's all you need to do to handle pagination with JSONAPI!

Currently the HTML template for paginator is based on Bootstrap 3.
