Immediately above this is a shouldComponentUpdate, which will prevent the component from being re-rendered even if we pass a new / different set of extraProps.

Right. Thank you for pointing that out!

Why are we doing this check with each prop?
Is there any special prop that we don't want it to make the component update?

Originally there were very few props, probably not more than just icon and size, and it was considered mostly a static component which would never need to be re-rendered.

Thanks for the explanation!
I'm still not sure what's the best approach to follow.
Currently I believe that we are re-rendering icons in some cases.

Would you recommend to remove those checks and let React do its job?
Or is there a good way of comparing extraProps directly?

Something like @wordpress/is-shallow-equal can provide some easier mechanism to compare all props:

shouldComponentUpdate( props, nextProps ) {
	return ! isShallowEqual( props, nextProps );
}

Which is effectively the same as using pure from @wordpress/compose.

But it's lost much of its value here. I don't know that it'd be necessary at all.


render() {
const { icon, size = 20 } = this.props;
const { icon, size = 20, ...extraProps } = this.props;
let path;

switch ( icon ) {

Can it cause any issues when the same props get passed down to Button and Dashicon?

This one should be tested:
https://github.com/WordPress/gutenberg/blob/master/packages/components/src/form-token-field/token.js#L72

It might apply aria-describedby twice which probably isn't expected.

Thank you @gziolo , that's a good concern.

Should we pass a specific iconProps?
I think it looks more declarative if we do this:

<Button aria-label={ label } { ...additionalProps } className={ classes }>
	{ isString( icon ) ? <Dashicon icon={ icon } ariaPressed={ ariaPressed } { ...iconProps } /> : icon }
	{ children }
</Button>

From the caller:

<ToolbarButton
	label={ __( 'Add block' ) }
	icon="plus-alt"
	onClick={ onInsertClick }
	iconProps={ { style: styles.addBlockButton, color: styles.addBlockButton.color } }
/>

What other solution do you think might be good?

{ children }
</Button>
);
