๐Ÿ† The Best Pagination Ruby Gem ๐Ÿฅ‡

~ 40x Faster!

[IPS Chart](docs/assets/images/ips-chart.png)

~ 36x Lighter!

[Memory Chart](docs/assets/images/memory-chart.png)

~ 35x Simpler!

[Objects Chart](docs/assets/images/objects-chart.png)

~ 1,410x More Efficient!

[Resource Consumption Chart](docs/assets/images/resource-consumption-chart.png)

Each dot in the visualization above represents the resources that Pagy consumes for one full rendering. The other gems consume hundreds of times as much for the same rendering.

The IPS/Kb ratio is calculated out of speed (IPS) and Memory (Kb): it shows how well each gem uses each Kb of memory it allocates/consumes.

๐Ÿ‘ If you like Pagy, give it a star! โญ

Thank you for showing your support!

๐Ÿคฉ It does it all. Better.

Code Structure

  • Pagy has a very slim core code very easy to understand and use (see more...)
  • It has a quite fat set of optional extras that you can explicitly require for very efficient and modular customization (see extras)
  • It has no dependencies: it produces its own HTML, URLs, i18n with its own specialized and fast code (see why...)
  • Its methods are accessible and overridable right where you use them (no pesky monkey-patching needed)

Unlike the other gems

  • Pagy is very modular and does not load any unnecessary code in your app (see why...)
  • It doesn't impose limits on your code even with collections|scopes that already used limit and offset (see how...)
  • It works with fast helpers OR easy to edit templates (see more...)
  • It raises real Pagy::OverflowError exceptions that you can rescue from (see how...) or use the overflow extra for a few ready to use common behaviors
  • It does not impose any difficult-to-override logic or output (see why...)

Better Components

Besides the classic pagination offered by the pagy_nav helpers, you can also use a couple of more performant alternatives:

  • pagy_nav_js: A faster and lighter classic looking UI, rendered on the client side with optional responsiveness:[bootstrap_nav_js](docs/assets/images/bootstrap_nav_js-w.png)

  • pagy_combo_nav_js: The fastest and lightest alternative UI (48x faster, 48x lighter and 2,270x more efficient than Kaminari) that combines navigation and pagination info in a single compact element:[bootstrap_combo_nav_js](docs/assets/images/bootstrap_combo_nav_js-w.png)

๐Ÿ˜Ž It's easy to use and customize

Code for basic pagination...

# Optionally override some pagy default with your own in the pagy initializer
Pagy::DEFAULT[:items] = 10        # items per page
Pagy::DEFAULT[:size]  = [1,4,4,1] # nav bar links

# Include it in the controllers (e.g. application_controller.rb)
include Pagy::Backend

# Include it in the helpers (e.g. application_helper.rb)
include Pagy::Frontend

# Wrap your collections with pagy in your actions
@pagy, @records = pagy(Product.all)
<%# Render the navigation bar in your views %>
<%== pagy_nav(@pagy) %>

(See Quick Start)

Customization for CSS frameworks...

# Require a CSS framework extra in the pagy initializer (e.g. bootstrap)
require 'pagy/extras/bootstrap'
<%# Use it in your views %>
<%== pagy_bootstrap_nav(@pagy) %>

(See the bootstrap extra)

Customization for special collections...

# Require some special backend extra in the pagy initializer (e.g. elasticsearch_rails)
require 'pagy/extras/elasticsearch_rails'

# Extend your models (e.g. application_record.rb)
extend Pagy::ElasticsearchRails

# Use it in your actions
response         = Article.pagy_search(params[:q])
@pagy, @response = pagy_elasticsearch_rails(response)

(See the elasticsearch_rails extra)

Customization for client-side|JSON rendering...

# Require the metadata extra in the pagy initializer
require 'pagy/extras/metadata'

# Use it in your actions
pagy, records = pagy(Product.all)
render json: { data: records,
               pagy: pagy_metadata(pagy) }

(See the metadata extra)

Customization for headers pagination for APIs...

# Require the headers extra in the pagy initializer
require 'pagy/extras/headers'

# Use it in your actions
pagy, records = pagy(Product.all)
render json: records

(See the headers extra)

More customization with extras...

Extras add special options and manage different components, behaviors, Frontend or Backend environments... usually by just requiring them (and optionally overriding some default).

Backend Extras

  • arel: Better performance of grouped ActiveRecord collections
  • array: Paginate arrays efficiently, avoiding expensive array-wrapping and without overriding
  • calendar: Add pagination filtering by calendar time unit (year, quarter, month, week, day)
  • countless: Paginate without the need of any count, saving one query per rendering
  • elasticsearch_rails: Paginate ElasticsearchRails response objects
  • headers: Add RFC-8288 compliant http response headers (and other helpers) useful for API pagination
  • meilisearch: Paginate Meilisearch results
  • metadata: Provides the pagination metadata to Javascript frameworks like Vue.js, react.js, etc.
  • searchkick: Paginate Searchkick::Results objects

Frontend Extras

Extra Features and Tools

  • Pagy::Console: Try any pagy feature or helper right in the irb/rails console even without any app or config
  • gearbox: Automatically change the number of items per page depending on the page number
  • i18n: Use the I18n gem instead of the pagy-i18n implementation
  • items: Allow the client to request a custom number of items per page with an optional selector UI
  • overflow: Allow for easy handling of overflowing pages
  • standalone: Use pagy without any request object, nor Rack environment/gem, nor any defined params method
  • support: Extra support for features like: incremental, auto-incremental and infinite pagination
  • trim: Remove the page=1 param from the first page link
