[React] Recompose: Override Styles & Elements Types in React

When we move from CSS to defining styles inside components we lose the ability to override styles with an external style sheet. We also lose the ability add the same class to different types of elements to style them consistently. Recompose allows us to regain the ability of override styles and to apply the same styles to different types of elements.

Feeling using Recompose is a good way to build npm module, custom libaray.

So the comoponent can be highly custmizable.

import React from 'react';
import {setDisplayName, componentFromProp, mapProps, defaultProps, compose} from 'recompose';
import Radium from 'radium';

const addStyle = style => mapProps(props => ({
    ...props,
    style: [
        props.style,
        style
    ]
}));

const style = {
    backgroundColor: 'black',
    color: 'white',
    transform: 'rotate(-13deg)',
    transition: 'all ease 0.43s',
    ':hover': {
        backgroundColor: 'orange',
        color: 'lightGreen',
        transform: 'rotate(0deg)'
    }
};

const enhance = compose(
    addStyle(style),
    setDisplayName('Button'),
    defaultProps({
        element: 'button'
                 }),
    Radium
);

export default enhance(componentFromProp('element'));

Using:

        <Button
            element={'button'}
            style={{borderRadius: '10px'}}
            onClick={onRemoveBox}
        >Remove</Button>

In the code, we are able to override the default style by passing 'style' from props:

const addStyle = style => mapProps(props => ({
    ...props,
    style: [
        props.style,
        style
    ]
}));

const enhance = compose(
    addStyle(style),
    setDisplayName('Button'),
    defaultProps({
        element: 'button'
                 }),
    Radium
);

Here we also using 'Radium', so that we can add 'hover' sudo effect.

We can also say what kind of element we want to show:

    defaultProps({
        element: 'button'
                 }),


        <Button
            element={'a'} href="http://google.fi"
            style={{borderRadius: '10px'}}
            onClick={onRemoveBox}
        >Remove</Button>

We can change to 'a' tag if we want.
