Agnostic pagination in plain Ruby

Tip

⭐ If you like Pagy, please support it with a Star! ⭐

💚 v3 was already quite snappy...

... and now it's more, with less.

• Compatible with all environments and collection types
• It can use OFFSET, COUNTISH, COUNTLESS, KEYSET, KEYNAV, SEARCH, and CALENDAR pagination techniques
• It supports server-side rendering or faster client-side rendering for popular CSS frameworks and APIs
• It autoloads ONLY the methods that you actually use, with almost zero configuration
• It boasts 100% test coverage for Ruby, HTML, and JavaScript end-to-end (E2E)

💚 Examples

Pagination code

# Include pagy in your code (usually application_controller.rb)
include Pagy::Method

# Offset-based pagination
@pagy, @records = pagy(:offset, Product.all)

# Keyset-based pagination (fastest technique)
@pagy, @records = pagy(:keyset, Product.order(my_order).all)

# Paginate your collection with one of several paginators
@pagy, @records = pagy(...)

See all the available paginators

JSON:API pagination

# JSON:API nested query string. E.g.: ?page[number]=2&page[size]=100
@pagy, @records = pagy(:offset, Product.all, jsonapi: true)
@pagy, @records = pagy(:keyset, Product.order(my_order).all, jsonapi: true)
render json: { links: @pagy.urls_hash, data: @records }

JSON-client pagination

render json: { pagy: @pagy.data_hash, data: @records }

Search server pagination

Available paginators: :elasticsearch_rails, :meilisearch, :rails_active_search, :searchkick, :typesense_rails

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

# Paginate with pagy:
search           = Product.pagy_search(params[:q])
@pagy, @response = pagy(:a_search_paginator, search)

# Or get pagy from paginated results:
@results = Product.search(params[:q])
@pagy    = pagy(:a_search_paginator, @results)

Calendar pagination

Combine time-range and offset pagination.

(Available time units: year, quarter, month, week, and day)

@calendar, @pagy, @records = pagy(:calendar, collection, year: {}, month: {}, offset: {})

<%== @calendar[:year].series_nav(:bootstrap) %>
<%== @calendar[:month].series_nav(:bootstrap) %>
<%== @pagy.info_tag %>
...
<%== @pagy.series_nav(:bootstrap) %>

Server side rendering

series_nav

Default :pagy, :bootstrap and :bulma styles shown.

<!-- Render server side nav bar helpers with different html and styles -->
<%== @pagy.series_nav %> <!-- pagy style -->
<%== @pagy.series_nav(:bootstrap) %>
<%== @pagy.series_nav(:bulma) %>

Client side rendering

# pagy.rb initializer
javascript_dir = Rails.root.join('app/javascript')
Pagy.sync_javascript(javascript_dir, 'pagy.mjs') if Rails.env.development?

series_nav_js

Faster and responsive

Dynamically fills the container width.

<!-- Render client side nav bar helpers with different html and styles -->
<%== @pagy.series_nav_js %> <!-- pagy style -->
<%== @pagy.series_nav_js(:bootstrap) %>
<%== @pagy.series_nav_js(:bulma) %>

input_nav_js

Fastest! Combines navigation and info in minimum space.

<!-- Render client side nav input helpers with different html and styles -->
<%== @pagy.input_nav_js %> <!-- pagy style -->
<%== @pagy.input_nav_js(:bootstrap) %>
<%== @pagy.input_nav_js(:bulma) %>

💚 Dev Tools

Integrate pagy with your app's themes interactively (watch demo), and ask specific questions to the Pagy AI right in your app! You need only a single line in your page/layout head to get the Pagy Wand and the Pagy AI:

<%== Pagy.dev_tools %>
