JSPM – react-display-name@0.2.4

Package Exports

react-display-name

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (react-display-name) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

npm install --save react-display-name

Get the displayName from a Component. This is a common pattern with React Higher Order Components (HoCs). This is a simple reusable utility to get the name of a component.

Usage:

import {expect} from 'chai';
import React, {Component} from 'react';
import getDisplayName from 'react-display-name';

const container = (WrappedComponent) => {
  class Container extends Component {
    static displayName = `Container(${getDisplayName(WrappedComponent)})`;
    render() {
      return (
        <WrappedComponent />
      );
    }
  }
  return Container;
}

class HelloWorld extends Component {
  render() {
    return (
      <div>Hello</div>
    );
  }
}

const HelloWorldPrime = container(HelloWorld);

expect(getDisplayName(HelloWorldPrime)).to.equal('Container(HelloWorld)');
expect(HelloWorldPrime.displayName).to.equal('Container(HelloWorld)');
