#micro frontends react

Microfrontends are considered as a solution to the problems of exponential growth, code duplication, and unclear ownership in older applications. Transitioning from a monolith to microfrontends involves decoupling the system and exploring options like a modular monolith. Microfrontends enable independent deployments and runtime composition, but there is a discussion about the alternative of keeping an integrated application composed at runtime. Choosing a composition model and a router are crucial decisions in the technical plan. The Strangler pattern and the reverse Strangler pattern are used to gradually replace parts of the monolith with the new application.

This talk discusses the challenges of scaling and maintaining applications and how architecture decisions can impact them. It introduces the concept of Microfrontend and its advantages of easier scaling, issue identification, and diversification of technology stacks. The implementation of Microfrontend at Red Hat is explained, including the use of a new framework, communication strategies, and the need for scalability and maintenance in large applications. The talk also covers the multiplying architecture framework of micro frontend and its core components. The implementation of Microfrontend in VS Code and examples of combining different frameworks into a single application are showcased. The issue of duplication of library loading is addressed using federated modules in webpack.

Microfrontends is an architecture used by big companies to split monolithic frontend applications into manageable parts. Maintaining a consistent look and feel across different microfrontends is a challenge. Sharing styles can be done through Vanilla CSS, CSS modules, or CSS in JS. JavaScript variables can be used in styles, but readability and runtime overhead are considerations. Sharing state in microfrontends can be achieved through custom events, broadcast channels, shared state managers, or custom PubSub implementations. Module federation with Vite allows for client composition and sharing dependencies. Configuration is similar to Webpack, and future work includes working on the QUIC framework.

Micro frontends are an architectural style where independent deliverable frontend applications compose a greater application. They allow for independent development and deployment, breaking down teams into feature verticals. React Native's architecture enables updating the JavaScript layer without going through the app store. Code Push can be used to deploy separate JavaScript bundles for each micro frontend. However, there are challenges with managing native code and dependencies in a micro frontend ecosystem for mobile apps.

This Talk discusses the architecture journey of a sports engagement platform, transitioning from a monolith to a microfrontend architecture. The ALEP microfrontend architecture is introduced to manage the complexity of a complex catalog and enable efficient deployment and version management. The deployment and release process involves using AliB and updating metadata in the deployment dashboard. The integration to React and TV development process involves using the AliB package and having independent lifecycles for packages. Shared code is used across different targets, and testing is done in a remote virtual lab. Focus management and key moments detection in sports are also addressed.
