Single SPA Micro

single-spa is a JavaScript library that enables micro frontends—multiple JavaScript applications running on the same web page, loaded and unloaded dynamically at runtime. Each application is independently built, tested, and deployed. The root application (orchestrator) loads micro frontends based on URL or other conditions. Single-spa handles mounting, unmounting, and lifecycle management. Micro frontends solve problems at organizational scale: enabling independent teams, independent deployments, and independent technology choices. single-spa is the de facto standard orchestration framework.
