Micro-Frontend Frameworks

Micro-frontend frameworks enable the development of web applications as a composition of multiple smaller applications, allowing teams to work independently on different parts of a larger application. They help in managing the complexity of large-scale applications by breaking them down into manageable pieces, each developed and deployed independently. This approach enhances scalability, maintainability, and the ability to use different technologies within the same application. Both qiankun and single-spa provide mechanisms for loading, unloading, and managing these micro-applications seamlessly, but they have different philosophies and implementation details that cater to various use cases.

Feature Comparison: qiankun vs single-spa

Framework Compatibility

  • qiankun:

    qiankun supports multiple frameworks out of the box, including React, Vue, Angular, and others. This flexibility allows teams to choose the best technology for their specific micro-apps without being locked into a single framework, making it easier to integrate existing applications.

  • single-spa:

    single-spa also supports multiple frameworks, but it requires a more structured setup for each micro-app. It allows developers to use different frameworks side by side, but the integration process can be more complex, requiring adherence to specific conventions.

Loading Mechanism

  • qiankun:

    qiankun employs a dynamic loading mechanism that allows micro-apps to be loaded on demand, which can significantly improve the initial load time of the application. It uses a single entry point to manage the loading of multiple micro-apps, ensuring that only the necessary code is loaded when required.

  • single-spa:

    single-spa uses a more explicit loading mechanism where each micro-app must declare its lifecycle methods. This provides fine-grained control over when and how each micro-app is loaded and unloaded, but it can lead to more boilerplate code and complexity in managing dependencies.

State Management

  • qiankun:

    qiankun provides a simple way to share state between micro-apps using a global event bus. This allows micro-apps to communicate and share data without tightly coupling them, promoting loose coupling and independent development.

  • single-spa:

    single-spa does not provide built-in state management solutions. Instead, it encourages developers to implement their own state management strategies, which can lead to more flexibility but also requires additional effort to ensure consistent state across micro-apps.

Community and Ecosystem

  • qiankun:

    qiankun has a growing community and ecosystem, with many plugins and integrations available. This can be beneficial for developers looking for additional tools and resources to enhance their micro-frontend architecture.

  • single-spa:

    single-spa has a well-established community and a variety of resources, including documentation and tutorials. Its ecosystem is robust, but it may not have as many plugins specifically tailored for micro-frontend development compared to qiankun.

Learning Curve

  • qiankun:

    qiankun is generally considered easier to learn, especially for teams already familiar with micro-frontend concepts. Its API is designed to be intuitive, making it accessible for developers of varying skill levels.

  • single-spa:

    single-spa has a steeper learning curve due to its more complex lifecycle management and the need for developers to understand the underlying principles of micro-frontend architecture. This can be a barrier for teams new to micro-frontends.

How to Choose: qiankun vs single-spa

  • qiankun:

    Choose qiankun if you need a more flexible, easy-to-use solution that supports various frameworks and offers a straightforward API for managing micro-applications. It is particularly beneficial for projects that require dynamic loading and unloading of micro-apps and have a strong emphasis on performance and user experience.

  • single-spa:

    Choose single-spa if you prefer a more structured approach with a focus on the lifecycle management of micro-apps. It is ideal for applications that require strict control over the loading and unloading process of micro-apps and where you want to enforce a single framework for all micro-apps.

Similar Npm Packages to qiankun

qiankun is a micro-frontend framework that allows developers to build and manage multiple frontend applications within a single application shell. It is designed to enable seamless integration of different frameworks and technologies, making it easier to scale applications and manage dependencies. With qiankun, developers can load and unload micro-apps dynamically, providing a smooth user experience while maintaining the independence of each micro-frontend. This approach is particularly beneficial for large applications that require modularization and the ability to evolve independently.

One of the primary alternatives to qiankun is single-spa. Single-spa is another micro-frontend framework that enables developers to build applications using multiple frameworks and libraries, such as React, Angular, Vue, and more. It provides a robust architecture for managing micro-frontends, allowing developers to load and unload applications based on routes or other triggers. Single-spa emphasizes flexibility and control over how micro-apps are integrated, making it a popular choice for teams looking to adopt a micro-frontend architecture.

While both qiankun and single-spa serve similar purposes in the micro-frontend ecosystem, they have different design philosophies and implementations. Qiankun is built on top of single-spa and offers additional features such as better support for dynamic loading, built-in state management, and a more straightforward API for managing micro-apps. On the other hand, single-spa provides a more granular level of control over the lifecycle of micro-apps, which can be beneficial in certain scenarios.

qiankun（乾坤）

In Chinese, qian(乾) means heaven and kun(坤) earth. qiankun is the universe.

Qiankun enables you and your teams to build next-generation and enterprise-ready web applications leveraging Micro Frontends. It is inspired by and based on single-spa.

🤔 Motivation

A quick recap about the concept of Micro Frontends:

Techniques, strategies and recipes for building a modern web app with multiple teams using different JavaScript frameworks. — Micro Frontends

Qiankun was birthed internally in our group during the time web app development by distributed teams had turned to complete chaos. We faced every problem micro frontend was conceived to solve, so naturally, it became part of our solution.

The path was never easy, we stepped on every challenge there could possibly be. Just to name a few:

  • In what form do micro-apps publish static resources?
  • How does the framework integrate individual micro-apps?
  • How to ensure that sub-applications are isolated from one another (development independence and deployment independence) and runtime sandboxed?
  • Performance issues? What about public dependencies?
  • The list goes on long ...

After solving these common problems of micro frontends and lots of polishing and testing, we extracted the minimal viable framework of our solution, and named it qiankun, as it can contain and serve anything. Not long after, it became the cornerstone of hundreds of our web applications in production, and we decided to open-source it to save you the suffering.

TLDR: Qiankun is probably the most complete micro-frontend solution you ever met🧐.
