Styles module

Generally, hard coding styles values in a component should be avoided. Any values that are likely to be used across different UI components should be split into their own module.

// Styles module
export const white = '#fff';
export const black = '#111';
export const blue = '#07c';

export const colors = {
  white,
  black,
  blue
};

export const space = [
  0,
  8,
  16,
  32,
  64
];

const styles = {
  bold: 600,
  space,
  colors
};

export default styles

Usage

// button.jsx
import React from 'react'
import { bold, space, colors } from './styles'

const Button = ({
  ...props
  }) => {
  const sx = {
    fontFamily: 'inherit',
    fontSize: 'inherit',
    fontWeight: bold,
    textDecoration: 'none',
    display: 'inline-block',
    margin: 0,
    paddingTop: space[1],
    paddingBottom: space[1],
    paddingLeft: space[2],
    paddingRight: space[2],
    border: 0,
    color: colors.white,
    backgroundColor: colors.blue,
    WebkitAppearance: 'none',
    MozAppearance: 'none'
  };

  return (
    <button {...props} style={sx}/>
  )
};
