    Vratix API Module Library

    Vratix API Module Library

    Easy to use Open Source modules that implement common API logic

    We created this library of reusable API modules to simplify API development because we were wasting too much time setting up basic functionality and researching the latest backend best practices. We wanted a repository of high-quality API modules we can reuse, copy and paste into our projects and have a working backend in seconds. Currently, the modules work for Express.js, however, we’re actively working to extend compatibility with other backend languages and popular Node.js frameworks. We...

    The Apache Struts web framework

    The Apache Struts web framework

    Mirror of Apache Struts

    The Apache Struts web framework is a free open-source solution for creating Java web applications. Web applications differ from conventional websites in that web applications can create a dynamic response. Many websites deliver only static pages. A web application can interact with databases and business logic engines to customize a response. Web applications based on JavaServer Pages sometimes commingle database code, page design code, and control flow code.
