Prevent print-only components from rendering when we aren't in the 'print mode'.

[alex-gokkun]

Correct me if I'm wrong but I haven't found an official way for a print-only component not being rendered.
Let's say that I have a component that depends on a plethora of props. Each prop change would trigger a re-render. It's a waste of effort if I'm not actually printing anything at the moment.
By subscribing to beforeprint and afterprint events I got a workaround but I cannot say I'm satisfied with it. It seems to violate separation of conerns.
Are there any plans on supporting this in the library?

Hm, official way is there. Let me a second

Did you try <Print printOnly...?

[alex-gokkun]

Yes, I did. It prevents the component from being displayed but doesn't prevent it from being rendered.

I got now. Thank you for the case!

There is a reason for this behavior.
If PrintProvider would re-render the children (whole components tree)
state of components will be lost.

I thinked a few minutes right now and realized the solution:
PrintProvider should triggers target re-renderings for printOnly and some another components Through pubsub in the context
(Like ‘redux’ or ‘material ui’ theming does it in its connect/withStyles hocs).

Do you wanna try to implement this?

I can try in a 2-4 next days.
