PhotoSwipe
JavaScript framework independent image gallery
PhotoSwipe is the first open-source gallery to support JavaScript-based image zooming. Even if a browser’s native zooming has been disabled, image zooming will still work. The gallery’s background will gradually fade out as the user zooms out. When the gesture is complete, the gallery will close. Gesture is added because close button in top right corner might be hard to reach on tall mobile devices while holding in one hand. Images can be changed even when current slide is zoomed. Swiping is not blocked during the transition. PhotoSwipe manipulates the browser’s history so that the user can link to each gallery item and close the gallery via the “back” button. The initial URL is restored when the gallery is closed. PhotoSwipe adds a history record when the gallery is opened, which allows the user to close it via the browser’s “back” button. This feature comes as a module. You can exclude it from the build entirely, or fork it to fit the requirements of your product’s URL structure. -

React Redux is maintained by the Redux team, and kept up-to-date with the latest APIs from Redux and React. Designed to work with React's component model. You define how to extract the values your component needs from Redux, and your component receives them as props. Creates wrapper components that manage the store interaction logic for you, so you don't have to write it yourself. Automatically implements complex performance optimizations, so that your own component only re-renders when the data it needs has actually changed. Redux itself is a standalone library that can be used with any UI layer or framework, including React, Angular, Vue, Ember, and vanilla JS.

ShowDoc
ShowDoc is a tool greatly applicable for an IT team to share documents
When we take over a module or project which has been developed by others, we always feel crazy watching at the codes without notes or comments. Programmers often want others to write technical documents, but not by themselves. Writing technical documents need lots of time and works, such as it needs to consider how to handle the format and layout of the documents. Beside, the man who writes the documents has to think all kinds of non-technical details. For example, which catalog should to be put in the newly-established word document. In general, all kinds of word documents are dispersively maintained by different people in a team. ShowDoc is a tool greatly applicable for an IT team to share documents online. It can promote communication efficiency between members of a team. With the development of mobile Internet, BaaS (Backend as a Service) becomes more and more popular. -

Size Limit
Calculate the real cost to run your JS app or lib
Size Limit is a JavaScript performance budget tool that measures the real cost of your JavaScript bundle and prevents regressions by enforcing limits in CI. It calculates not just raw bundle size, but also download and execution time under configurable network conditions, giving a more realistic sense of what users experience. The tool is modular: it offers a CLI and multiple plugins (file, webpack, time) plus presets tailored to different use cases, from big single-page apps to small npm libraries. When integrated with GitHub Actions, CircleCI, or other CI systems, it runs on every commit or pull request, failing the pipeline if a change exceeds the configured budget. It can also annotate pull requests with comments that highlight how the bundle changed, making performance regressions visible to reviewers early. With the --why flag, size-limit can analyze what contributes most to bundle size and show a dependency breakdown (using Statoscope). -

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.
