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.

See the Detailed Gems Comparison for full details.

• Pagy has a very slim core code very easy to understand and use.
• 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
• Its methods are accessible and overridable right where you use them (no pesky monkey-patching needed)

• Pagy is very modular and does not load any unnecessary code (see why...)_
• It doesn't impose limits 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 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

# 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)

Optionally set your defaults in the pagy initializer:

# 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
# Better user experience handled automatically
require 'pagy/extras/overflow'
Pagy::DEFAULT[:overflow] = :last_page

<%# Render a view helper in your views (skipping nav links for empty pages) %>
<%== pagy_nav(@pagy) if @pagy.pages > 1 %>

Or, choose from the following view helpers:

View Helper Name	Preview (Bootstrap Style shown)
pagy_nav(@pagy)
pagy_nav_js(@pagy)
pagy_info(@pagy)
pagy_combo_nav_js(@pagy)
pagy_items_selector_js
pagy_nav(@calendar[:year]) pagy_nav(@calendar[:month]) (other units: :quarter, :week, :day and custom)

(See the Quick Start)

# 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 all the CSS Framework Extras)

# 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 all the Search Extras)

# 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 all the Backend Tools)

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

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

(See all the Backend Tools)

• The master branch is the latest rubygem-published release. It also contains docs and comment changes that don't affect the published code. It is never force-pushed.
• The dev branch is the development branch with the new code that will be merged in the next release. It could be force-pushed.
• Expect any other branch to be internal, experimental, force-pushed, rebased and/or deleted even without merging.
