"If I wrap every mdbreact component (as an example) in loadable, would webpack extract those components into independent chunks? Could it execute this operation?"

- Not sure if this will work with mdbreact as a dependency.

"if I clone repo, would it include pro components?"

- Yes, and then you could use f.e. Loadable to lazy load your desired components from /src/components

So this should answer the previous thesis.

I've downloaded package approx 2 moths ago. Discovered, that now it weights only 386 K. It exceeds recommended limit, but very much better than 1,4 M!

Is it possible to uclude in package source codes? React-bootstrap for example has lib directory with source codes, so I can

import SomeComponent from 'react-bootstrap/lib/SomeComponent'

It gives me possibility to manage bundle size manually.

And one more question. If I were to use dynamic import by means of, for ex, react Loadable, would it give any effect conserning bundle size if deffered loading concerns components in mdbreact.js? 

I see,

That's the case in our package, it doesn't cooperate with tree shaking for now.

We are hardly working on reducing the package size and to independence.
But our priority now is to bring on fresh and updated documentation so that proces is slowed down for now.

Will keep you updated.

No. I've checked by means of  this plugin.  And result is that 1,4 M of total bundle size is mdbreact.js.

I've tried tree shaking, this plugin and so on. Nothing gains any reasonable size reducing. I've tried to intentionally make dead code. For ex, my index.js (entry) renders code like this

<Router>

<Main/>

</Router

I've tried to comment this and render something like 

<p>Hello, world</p>

Nothing. 1,4 M.

May be I wrongly understand tree shaking. I think so that if I import only component Fa (for ex) provided that Fa don't imports in turn some other component, then after tree shaking there should be leaved only this component in resulting bundle.  

I assume those files are your written code?

Webpack provides some advice in how to split the code https://webpack.js.org/guides/code-splitting/

Here are some methods how to reduce your bundle.
