    Opal jQuery

    Opal jQuery

    jQuery for Opal

    opal-jquery provides DOM access to opal by wrapping jQuery (or zepto) and providing a nice ruby syntax for dealing with jQuery instances. opal-jquery provides an Element class, whose instances are toll-free bridged instances of jQuery objects. Just like ruby arrays are just javascript arrays, Element instances are just jQuery objects. This makes interaction with jQuery plugins much easier. Also, Element will try to bridge with Zepto if it cannot find jQuery loaded, making it ideal for mobile applications as well. The request is actually triggered inside the HTTP. get method, but due to the async nature of the request, the callback and errback handlers can be added anytime before the request returns.

    Pedestal

    Pedestal

    The Pedestal Server-side Libraries

    Pedestal is a set of libraries that we use to build services and applications. It runs in the back end and can serve up whole HTML pages or handle API requests. There are a lot of tools in that space, so why did we build Pedestal? We had two main reasons. Pedestal is designed for APIs first. Most web app frameworks still focus on the "page model" and server-side rendering. Pedestal lets you start simple and add that if you need it. Pedestal makes it easy to create "live" applications. Applications must respond with immediate feedback even while some back-end communication goes on. Pedestal makes it easy to deliver server-sent events and asynchronous updates. Pedestal works with a huge variety of containers and deployment options. Deploy applications or microservices on unikernels, Docker containers, or JAR files. Pedestal supports Tomcat, Jetty, Immutant (with Undertow), Vert.x, nginx, and Netty.

    Phlex

    Phlex

    Object-oriented views in Ruby

    Phlex is a Ruby-based framework for building HTML and SVG views using object-oriented programming principles, offering a unique alternative to traditional template systems like ERB. It allows developers to write UI components entirely in Ruby, providing full control over structure, logic, and rendering without mixing HTML and templating syntax. One of its key advantages is performance, as it can render HTML extremely quickly while maintaining predictable scaling even with complex component hierarchies. Phlex integrates seamlessly with Ruby on Rails and supports common tools such as Tailwind CSS, Stimulus, and Turbo, making it easy to incorporate into modern Rails applications. It also emphasizes safety and maintainability by preventing common issues such as cross-site scripting through structural design and strict data handling. Developers benefit from reusable components, modular architecture, and the ability to stream content for improved performance and user experience.

    Prawn

    Prawn

    Fast, Nimble PDF Writer for Ruby

    Prawn is a pure Ruby PDF generation library that provides a lot of great functionality while trying to remain simple and reasonably performant. Extensive text rendering support, including flowing text and limited inline formatting options. Comprehensive internationalization features, including full support for UTF-8 based fonts, right-to-left text rendering, fallback font support, and extension points for customizable text wrapping. Support for PDF outlines for document navigation. Low level PDF features, allowing users to create custom extensions by dropping down all the way to the PDF object tree layer. (Mostly useful to those with knowledge of the PDF specification). If you are looking for a highly flexible PDF document generation system, Prawn might be the tool for you. It is not a reporting tool or a publishing toolchain, though it could be fairly easily used to build those things.

    Pundit

    Pundit

    Minimal authorization through OO design and pure Ruby classes

    Pundit (varvet/pundit) is a Ruby gem that provides a simple and effective framework for adding authorization logic to Rails (or other Ruby) applications. It centers around policy classes—one policy per model or resource—that define what actions a given user is permitted to perform (e.g., show?, update?, destroy?). Each policy method returns a boolean, and can be structured using combinators or shared logic to keep things DRY. In controllers and views, Pundit provides helpers like authorize, policy_scope, and policy to enforce those rules cleanly and consistently. The policy_scope feature is especially helpful—it restricts index or list queries to only the records the current user can see by applying scopes defined in the policy class. Pundit encourages placing authorization logic close to the model domain without muddling controllers or views, making permissions easier to reason about and testable.

    Rein

    Rein

    Database constraints made easy for ActiveRecord

    Data integrity is a good thing. Constraining the values allowed by your application at the database level, rather than at the application level, is a more robust way of ensuring your data stays sane. Unfortunately, ActiveRecord doesn't encourage (or even allow) you to use database integrity without resorting to hand-crafted SQL. Rein (pronounced "rain") adds a handful of methods to your ActiveRecord migrations so that you can easily tame the data in your database. All methods in the DSL are automatically reversible, so you can take advantage of reversible Rails migrations.

    Ruby-processing

    Ruby-processing

    Bridge between the Processing creative-coding framework and Ruby

    Ruby-processing is a bridge between the Processing creative-coding framework (originally Java-based) and the Ruby language, created to let developers and artists write Processing sketches using Ruby syntax. It enables the well-known graphics, animation, interaction and sketching patterns of Processing in a Ruby environment, which can be appealing to those who prefer Ruby’s syntax or already live in the Ruby ecosystem. Though the project is now deprecated and newer alternatives exist, it remains an excellent historical example of how to embed a drawing/graphics API into another language and how creative coding communities evolve. For educators or artists exploring coding visually, Ruby-Processing provided a low-barrier entry by combining a high-level language (Ruby) with an expressive graphics library. It also demonstrates how open-source communities wrap frameworks into new environments for accessibility and experimentation.

    ajax-datatables-rails

    ajax-datatables-rails

    A wrapper around DataTable's ajax methods that allow synchronization

    DataTables is a nifty jQuery plugin that adds the ability to paginate, sort, and search your HTML tables. When dealing with large tables (more than a couple of hundred rows) however, we run into performance issues. These can be fixed by using server-side pagination, but this breaks some DataTables functionality. ajax-data tables-rails is a wrapper around DataTables ajax methods that allow synchronization with server-side pagination in a Rails app. It was inspired by this Railscast. I needed to implement a similar solution in a couple of projects I was working on, so I extracted a solution into a gem. The final goal of this gem is to generate JSON content that will be given to jQuery DataTables. All the data table customizations (header, tr, td, CSS classes, width, height, buttons, etc.) must take place in the javascript definition of the data table. jQuery DataTables is a very powerful tool with a lot of customization available. Take the time to read the doc.

    factory_bot

    factory_bot

    A library for setting up Ruby objects as test data

    factory_bot is a fixtures replacement with a straightforward definition syntax, support for multiple build strategies (saved instances, unsaved instances, attribute hashes, and stubbed objects), and support for multiple factories for the same class (user, admin_user, and so on), including factory inheritance. factory_bot provides a framework and DSL for defining and using factories - less error-prone, more explicit, and all-around easier to work with than fixtures. Each factory has a name and a set of attributes. The name is used to guess the class of the object by default. It is recommended that you have one factory for each class that provides the simplest set of attributes necessary to create an instance of that class. If you're creating ActiveRecord objects, that means that you should only provide attributes that are required through validations and that do not have defaults. Other factories can be created through inheritance to cover common scenarios for each class.
