Add External Stylesheets/Pens

Any URL's added here will be added as <link>s in order, and before the CSS in the editor. If you link to another Pen, it will include the CSS from that Pen. If the preprocessor matches, it will attempt to combine them before processing.

JavaScript

Babel includes JSX processing.

Add External Scripts/Pens

Any URL's added here will be added as <script>s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.

JS

              
                import React from 'react';

//The most basic form of this is
const MyComponent = () => (
  <ul>
    // some list
  </ul>
)

//Another simple form without using ES6 arrow 
const Username = function(props) {
  return (
    <p>The logged in user is: {prpos.username} </p>
  )
}

//The above can be done in a single line vis ES6 arrow function, destructuring and implicit returns

const Username = ({username}) => <p>The logged in user is: {username}</p>

// when component has no logic outside JSX
const MyComponent = ({names}) => (
  <ul className="list">
    {names.map(name => <MyComponentList name={name} />)}    
  </ul>
);

export default MyComponent;

// when component fits on one line
const ListItem = (props) => <li className="list-item">{props.item.name}</li>;

// when component needs logic outside JSX
const Body = (props) => {
  let items = transformItems(props.rawItems);
  return (
    <div>
      <h1>{props.header}</h1>
      <List items={ items } />
    </div>
  );
};

//Equivalent to the previous example without the ES6 arrow
function Page(props, context) {
  return (
  <div>
    <Body header="My List" rawItems={props.rawItems} />
  </div>
  );
}
