qiankun（乾坤）

In Chinese traditional culture qian means heaven and kun stands for earth, so qiankun is the universe.

An implementation of Micro Frontends, based on single-spa, but made it production-ready.

🤔 Motivation

As we know what micro-frontends aims for:

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

Modularity is very important for large application. By breaking down a large system into individual sub-applications, we can achieve good divide-and-conquer between products and when necessary combination, especially for enterprise applications that usually involve multi-team collaboration. But if you're trying to implement such a micro frontends architecture system by yourself, you're likely to run into some tricky problems:

• In what form do sub applications publish static resources?
• How does the main application integrate individual sub-applications?
• How do you ensure that sub-applications are independent of each other (development independent, deployment independent) and runtime isolated?
• Performance issues? What about public dependencies?
• And so on...

After solving these common problems of micro frontends, we extracted the kernel of our solution after a lot of internal online application testing and polishing, and then named it qiankun.

Probably the most complete micro-frontends solution you ever met🧐.
