Qiankun is a micro-frontend orchestration framework designed to compose multiple independent web applications into a single, unified interface. It functions as a JavaScript library that manages the lifecycle of autonomous applications, allowing them to coexist within a shared browser environment while maintaining their independence.
The framework enables cross-framework integration, allowing developers to combine applications built with different technologies into one cohesive system. It provides a runtime sandbox that isolates global variables and prevents style conflicts between applications, ensuring that individual modules do not interfere with the host environment or each other.
To support large-scale web systems, the framework utilizes HTML-based entry points and standardized lifecycle hooks to manage the mounting, unmounting, and updating of sub-applications. It also includes performance optimization features such as idle-time asset prefetching, which downloads resources for inactive applications to reduce latency during navigation.
