Imagine I am enhancing a Fabric component by adding custom styles and wishing to combine any additional styles passed in through its props. Here's the solution I've devised:
const { TextField, Fabric , IButtonProps, mergeStyleSets } = window.Fabric;
const MyTextField = (props: IButtonProps) => {
const { styles, ...otherProps } = props;
const myStyles = stylesProps => {
// props.styles can be a function, an object or undefined
const stylesAsObject = typeof (styles) === "function" ? styles(stylesProps) : styles;
return mergeStyleSets({ root: { maxWidth: 250 }, field: { backgroundColor: "pink"}}, stylesAsObject);
};
return <TextField styles={myStyles} {...otherProps} />;
}
const TextFieldExample () => (<MyTextField readOnly value="My text field" styles={{field: { fontWeight: 600}}} />
);
ReactDOM.render(<Fabric><TextFieldExample /></Fabric>, document.getElementById('content'));
This method works, yet it seems somewhat lengthy.
I wonder if there exists a version of mergeStylesets that would allow me to simply write:
const myStyles = mergeStylesets({ root: { maxWidth: 250 }, field: { backgroundColor: "pink"}}, props.styles);
