ca-ui-react-themer

react-themer

Overview

React bindings for themer. This library helps making react components themeable and extensible.

This library provides a React decorator that developes can use to style their components. Other developers will then be able to easily replace or extend the default component theme.

This library supports all class-based styling mechanisms, for example:

• Global CSS
• CSS Modules
• JSS
• CSJS
• Aphrodite

This library is meant to be used in all CA components.

Installation

npm install ca-ui-react-themer --save

Usage

Basic Usage

Component Definition

import React from 'react';
import reactThemer from 'ca-ui-react-themer';
import theme from './styles.(css|scss|jss.js)';
 
const Header = (props) => {
  const { styles } = props.theme;
 
  return (
    <div className={styles.root}>
      <h1 className={styles.title}>{props.content}</h1>
    </div>
  );
};
 
export default reactThemer(theme)(Header);

Component Usage

import React from 'react';
import { render } from 'react-dom';
import Header from './Header';
 
render(<Header content="Some content here" />, document.getElementById('app'));

Adding Middleware

import React from 'react';
import { render } from 'react-dom';
import themer from 'ca-ui-themer';
import Header from './Header';
 
// see `themer`(https://github.com/CAAPIM/themer) for how to set middlewares
themer.setMiddleware((component, resolvedTheme) => {
  // middleware code to execute...
  return component; // return component
});
 
render(<Header content="Some content here" />, document.getElementById('app'));

Adding a Custom react-themer Instance

themer.js

import { create as createThemer } from 'ca-ui-themer';
import { create as createReactThemer } from 'ca-ui-react-themer';
 
// create themer instance.
const themer = createThemer();
 
// Set middleware for the newly created instance
themer.setMiddleware((component, resolvedTheme) => {
  // middleware code to execute...
  return component; // return component
});
 
const reactThemer = createReactThemer(themer);
 
export default reactThemer;

Using Decorator in Component

import React from 'react';
import themer from '../themer';
import theme from './styles.(css|scss|jss.js)';
 
const Header = (props) => {
  const { styles } = props.theme;
 
  return (
    <div className={styles.root}>
      <h1 className={styles.title}>{props.content}</h1>
    </div>
  );
};
 
export default themer(theme)(Header);
