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🧐.
