The Trellis Framework is a software development framework designed to simplify the creation of web applications. It provides a structured way to build applications by offering reusable components and tools that streamline the development process. This framework is particularly useful for developers looking to create scalable and maintainable applications efficiently. One of the key features of the Trellis Framework is its focus on modularity, allowing developers to break down applications into smaller, manageable parts. This approach enhances collaboration among teams and makes it easier to update or modify specific components without affecting the entire application. Overall, the Trellis Framework aims to improve productivity and code quality in web development.
