Creating micro-frontend apps with single-spa

The concept of micro-frontends extends the principles of microservices to the frontend, allowing developers to break down their frontend into smaller, independent components for faster testing, development, and deployment. Introduced in 2016 by ThoughtWorks Tech Radar, this approach caters to the increasing need for frontend developers to work collaboratively on integrated projects. The article provides a practical guide to building a micro-frontend application using single-spa and React, detailing the setup and configuration process. Single-spa is a JavaScript router that facilitates the integration of multiple applications built on different frameworks, enabling the creation of cohesive applications from various micro-frontends. The example project consists of several applications, such as a navbar, homepage, about page, and contact page, each managed by separate micro-frontend apps. The article emphasizes careful configuration of the root application and the use of Bootstrap for styling, highlighting the advantages of single-spa's live-reload feature and encouraging readers to explore additional functionalities through its official documentation.
