    Sails

    Sails

    The MVC framework for Node.js

    Build custom, enterprise-grade Node.js apps with Sails! Sails.js is a web framework designed to make building practical, production-ready Node.js apps fast and easy. It is the most popular MVC framework for Node.js, resembling the MVC pattern of frameworks like Ruby on Rails but with support for the requirements of modern apps, such as a data-driven API with a scalable, service-oriented architecture. Sails is compatible with any front-end as well as any database thanks to its powerful ORM Waterline. Sails actions are compatible with Connect middleware, allowing you in most cases to simply paste code into Sails from an existing Express project and have everything work. You'll also be able to use WebSockets to talk to your API, and vice versa.

    Sequence.js

    Sequence.js

    The responsive CSS animation framework for creating unique sliders

    Sequence.js is a responsive CSS animation framework created for building interactive sliders, presentations, banners, and other step-based web applications using mostly HTML and CSS. Instead of relying heavily on JavaScript animation logic, the framework controls transitions through CSS class states such as seq-in and seq-out, allowing developers to use familiar front-end workflows and native browser rendering capabilities. The project emphasizes flexibility, enabling developers to animate virtually any CSS property without being constrained by rigid templates or predefined transition systems. Sequence.js supports responsive design, touch navigation, hardware acceleration, and optional dependencies like Hammer.js and ImagesLoaded for advanced interaction handling. Its architecture was rebuilt in vanilla JavaScript to improve performance and remove reliance on jQuery while maintaining broad browser compatibility.

    Serverless Webpack

    Serverless Webpack

    Serverless plugin to bundle your lambdas with Webpack

    A Serverless Framework plugin to build your lambda functions with Webpack.

This allows the plugin to fully utilize WebPack's Tree-Shaking optimization. Configuration possibilities range from zero-config to fully customizable. Support of serverless package, serverless deploy and serverless deploy function. Support of serverless invoke local and serverless invoke local --watch. Support of serverless run and serverless run --watch. Integrates with serverless-offline to simulate local API Gateway endpoints. Cleaned up configuration. You should now use a custom.webpack object to configure everything relevant for the plugin. The old configuration still works but will be removed in the next major release.

    Sinon.JS

    Sinon.JS

    Test spies, stubs and mocks for JavaScript

    Standalone test spies, stubs and mocks for JavaScript. Works with any unit testing framework. As before, Sinon.JS provides utilities that help test frameworks reduce the boiler-plate. As of Sinon 10 we stopped maintaining compatibility with legacy browsers. Instead, we focus on compatibility with evergreen browsers, Node.js LTS versions and recent Safari versions. The most up-to-date reference on which runtimes and browsers we support can be found by looking at our compatibility docs. Fake timers are synchronous implementations of setTimeout and friends that Sinon.JS can overwrite the global functions with to allow you to more easily test code using them. A test spy is a function that records arguments, return value, the value of this and exception thrown (if any) for all its calls. There are two types of spies: Some are anonymous functions, while others wrap methods that already exist in the system under test. Mocks should only be used for the method under test.

    SocketCluster

    SocketCluster

    Highly scalable realtime pub/sub and RPC framework

    Highly scalable pub/sub and RPC toolkit optimized for async/await. Pub/sub-channels are very cheap. You can have millions of unique channels without worrying about memory or CPU usage. Channels are automatically cleaned up when they are no longer used. The socket cluster CLI tool exposes kubectl (Kubernetes) shortcut commands to make deploying your app to any Kubernetes cluster really easy. All necessary Kubernetes .yaml files are provided. After deploying your app to a Kubernetes cluster, you can scale indefinitely by using the kubectl scale deployment command to add more SCC-worker and SCC-broker instances as needed. You can perform asynchronous operations anywhere along a socket's inbound or outbound stream without any risk of disrupting the message processing order. Awaiting asynchronous actions along a socket's inbound or outbound streams can cause messages to pile up.
