Meteor Array Reactive Paginator

This package is heavily based on skaleb-simple-paginator by @ToeFungi. I made some modifications to make it an atmosphere package.

Installation

$ meteor add nasuke:simple-paginator

Usage

In some client code:

import { paginator } from 'meteor/nasuke:simple-paginator'

const array = [{ a: 1 }, { a: 2 }, { a: 3 }];

Template.MyTemplate.onCreated(function () {
    this.paginator = paginator.setArray(array);
});

The paginator object exported by this package has some methods:

paginator.setArray

Sets the array to paginate. Must be the first method you call, probably inside your template's onCreated hook. Returns paginator.

paginator.getPage

Returns an array with the elements for the current page.

In myTemplate.js

Template.myTemplate.helpers({
    items() {
        return paginator.getPage();
    }
});

In myTemplate.hmtl

<template name='MyTemplate'>
  <div class='items-list'>
    {{#each item in items}}
      <div class='item'>{{ item.a }}</div>
    {{/each}}
  </div>
<template>

paginator.getTotalPages

Returns an array of numbers with the proper number of pages for your array (e.g. [1, 2, 3]) suitable for use with an each in your html:

In myTemplate.js

Template.MyTemplate.helpers({
  totalPages() {
    return paginator.getTotalPages();
  }
});

Then in myTemplate.html

<template name='MyTemplate'>
  <ul class='pages-wrapper'>
    {{#each item in totalPages}}
      <li class='page'>{{ item }}</li>
    {{/each}}
  </ul>
<template>

paginator.currPageNumber

Returns the current page you're in. Useful for adding an active class to the current page in the html.

In myTemplate.js

Template.myTemplate.helpers({
  active(currPage) {
    return paginator.currPageNumber() === currPage ? 'active' : '';
  }
});

In myTemplate.html

<template name='MyTemplate'>
  <ul class='pages-wrapper'>
    {{#each item in totalPages}}
      <li class='page {{ active item }}'>{{ item }}</li>
    {{/each}}
  </ul>
<template>

paginator.incrementPage

Adds 1 to the current page, if the current page is the last, does nothing. Meant to be used inside an event to navigate to the next page. Returns paginator.

paginator.decrementPage

Subtracts 1 to the current page, if the current page is the first, does nothing. Meant to be used inside an event to navigate to the previous page. Returns paginator.

paginator.setPageNumber(pageNumber)

Sets the current page to the pageNumber arg passed. Default is 1. Returns paginator

paginator.setPageSize(pageSize)

Sets the number of elements to return for each page to pageSize arg passed. Default is 3. Returns paginator
