    Classnames

    Classnames

    A simple javascript utility for conditionally joining classNames

    Classnames is a minimal JavaScript utility that helps you construct CSS class strings based on conditional logic. Instead of manually concatenating strings, developers can pass any combination of strings, arrays, or objects, and the library will output a clean, space-separated class list. When you provide an object, the keys represent class names and the boolean values determine whether each class should be included in the final string. This reduces boilerplate and the risk of typos or stray spaces, especially in React, Vue, or other component-based UIs where dynamic styling is common. ...

    Passport

    Passport

    Simple, unobtrusive authentication for Node.js

    ...It doesn’t impose specific user model structures or storage strategies but instead offers a unified API driven by “strategies”—small plugins that encapsulate authentication logic for protocols such as local username/password, OAuth, OpenID, SAML, and many others. This design allows developers to plug in only the strategies they need and swap or add new ones without rewriting core application logic, making Passport highly adaptable for diverse authentication requirements. Passport hooks into Express (and similar frameworks) using middleware functions that run during the request lifecycle, simplifying tasks like session management, credential validation, and user serialization.

    vuedarkmode

    vuedarkmode

    A minimalist dark design system for Vue.js

    The vuedarkmode repository is a lightweight utility for front-end projects built with Vue.js that enables easy toggling between light and dark themes (or color modes), supporting persistent user preference (e.g. via local storage). It abstracts the boilerplate and complexity around theme switching: instead of manually wiring up CSS classes, media queries, or state logic, you can integrate vuedarkmode and have theme toggling out-of-the-box. That makes it easier for developers to support dark mode reliably across components and pages, ensuring consistency and smoother user experience. The package likely includes reactive hooks or components that detect system/theme preferences and allow switching dynamically, and may also provide CSS or class-based mechanisms to adapt styling accordingly. ...

    The JSON Form library is a JavaScript client-side library that takes a structured data model defined using JSON Schema as input and returns a Bootstrap 3-friendly HTML form that matches the schema. The generated HTML form includes client-side validation logic that provides direct inline feedback to the user upon form submission (provided a JSON Schema validator is available). If values are valid, the JSON Form library uses submitted values to create the JavaScript data structure that matches the data model. The layout of the generated HTML form may be entirely fine-tuned through a simple declarative mechanism. ...
