How to use styled-components in react component

Question

Total newbie on using styled-components. I'm wondering what's the usage of it? How should I implement component life cycle methods after styling it? For simplicity sake I've removed all the other style.

import styled from 'styled-components';

const Button = styled.button`
  background-color: 'green'
`

export default Button;

I'm wondering how do I further working on this Button component?

Traditionally we can declare a class-based component and implement some lifecycle methods, but now with this styled-components, I'm not really sure how to combine them together as they are really the single Button Component?

UPDATES:

Full sourcecode for Button.js. By having the below code, all styles will be gone and I can't understand the problem

import React from 'react';
import styled from 'styled-components';
// import Button from 'react-bootstrap/Button';

import color from '../config/color';

const Button = ({ children, onPress }) => (
  <button type="button" onPress={onPress}>{children}</button>
);

const StyledButton = styled(Button)`
  width: 12rem;
  height: 54px;
  font-size: 1rem;
  background-color: ${(props) => {
    if (props.inverted) return 'white';
    if (props.disabled) return color.disabled;
    return (props.color || color.primary);
  }};
  color: ${(props) => {
    if (props.disabled) return color.disabledText;
    if (props.inverted) return (props.color || color.primary);
    return 'white';
  }};
  border:${(props) => (props.inverted ? `2px solid ${props.color || color.primary}` : 'none')};
  border-radius: 60px;

  &:hover {
    filter: ${(props) => (props.inverted || props.disabled ? 'none' : 'brightness(95%)')}
  }
`;

export default StyledButton;

In order to style a custom react component you can pass on the custom component name as argument to styled. According to the doc:

The styled method works perfectly on all of your own or any third-party component, as long as they attach the passed className prop to a DOM element.

import React from 'react';
import styled from 'styled-components';
// import Button from 'react-bootstrap/Button';

import color from '../config/color';

const Button = ({ children, className onPress }) => (
  <button type="button" className={className} onPress={onPress}>{children}</button>
);

const StyledButton = styled(Button)`
  width: 12rem;
  height: 54px;
  font-size: 1rem;
  background-color: ${(props) => {
    if (props.inverted) return 'white';
    if (props.disabled) return color.disabled;
    return (props.color || color.primary);
  }};
  color: ${(props) => {
    if (props.disabled) return color.disabledText;
    if (props.inverted) return (props.color || color.primary);
    return 'white';
  }};
  border:${(props) => (props.inverted ? `2px solid ${props.color || color.primary}` : 'none')};
  border-radius: 60px;

  &:hover {
    filter: ${(props) => (props.inverted || props.disabled ? 'none' : 'brightness(95%)')}
  }
`;

export default StyledButton;
