Qiankun
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.
Features
- Micro-Frontend Frameworks - Provides a runtime environment that orchestrates multiple independent web applications into a single cohesive interface while isolating their styles and global states.
- Frontend Architecture Patterns - Builds large-scale web systems by composing multiple independent applications into a single unified interface.
- Frontend Frameworks - Composes multiple independent web applications into a single unified interface while isolating styles and global environments.
- Micro-Frontend Libraries - Provides a solution for loading and managing the lifecycle of autonomous web applications.
- Micro-Frontend Orchestrators - Combines multiple autonomous web applications into a single unified interface for seamless user navigation.
- Global Environment Sandboxes - Uses JavaScript proxies to intercept and isolate global object modifications, preventing state leakage.
- Cross-Framework Integration Utilities - Connects autonomous web applications built with different technologies into one cohesive system.
- Micro-Frontend Routers - Maps browser URL changes to specific application entry points to manage navigation state across multiple modules.
- Cross-Framework Integrators - Connects multiple autonomous web applications into a single unified system regardless of the underlying technology.
- Global Application Contexts - Protects the global scope by preventing sub-applications from interfering with each other through shared variables.
- Style Isolation Mechanisms - Prevents visual conflicts by ensuring styles defined in one sub-application do not leak into others.
- Application Lifecycle Hooks - Establishes standard entry points for mounting, unmounting, and updating sub-applications.
- Lifecycle Hooks - Coordinates the mounting and unmounting of independent applications through a standardized set of lifecycle events.
- Application Lifecycle Managers - Executes standardized initialization, mounting, and unmounting routines to control sub-application rendering.
- Frontend Environments - Protects the global browser environment and prevents style conflicts when running multiple independent applications.
- HTML Entry Loaders - Provides a mechanism to load and execute independent sub-applications via their entry HTML files.
- Micro Frontend Frameworks - Production-ready framework for implementing micro frontend architectures.
- Application Entry Point Registrars - Simplifies integration by loading sub-applications directly through standard HTML entry points.
- Shadow DOM Utilities - Wraps sub-application content in isolated DOM trees to prevent CSS rules from bleeding across the interface.
