In the context of enterprise applications, while back-end systems are often modularized into microservices, front-end systems tend to remain monolithic, resulting in inefficiencies and maintenance challenges. This monolithic front-end structure requires comprehensive knowledge of all backend services and can become a bottleneck due to its size and complexity. The article proposes a solution involving the modularization of front-end applications by dividing them into independent modules that interact with relevant backend services, similar to a "portal-like" application such as Microsoft Office. This approach reduces the impact of backend changes, allows for easier updates and feature flagging, and distributes knowledge across multiple teams. Tools like Piral can support this architecture by offering a framework for developing modular front-end applications with features like extension slots and shared data. The solution emphasizes the importance of existing tools and libraries to manage challenges related to deployment, tooling, and debugging while enabling a more scalable and maintainable front-end structure.
