The loadingFn is the primary function for mounting the view.
It is required to be defined for each of the AKASHA Core's
micro-frontend type:
- application
- widget
- extension-point
- content-block
Single-spa library (which is used under the hood) handles these micro-frontends through some lifecycle methods:
- bootstrap
- mount
- unmount
- (optional) update -> this is not currently used
The loading function should return a Promise that, when resolved, should return these lifecycle hooks.
For React, and other popular ui libraries, single-spa provides adapter libraries to automatically call the rendering functions of these ui libs. For React, it's called single-spa-react. if you are interested to dive deeper (although not required) you can check their docs
