Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

React DnD Preview NPM Version dependencies Status devDependencies Status

Try it here!

This project is a React component compatible with React DnD that can be used to emulate a Drag'n'Drop "ghost" when a Backend system doesn't have one (e.g. react-dnd-touch-backend).

See the migration section for instructions when switching from 4.x.x.

Installation

npm install react-dnd-preview

Usage & Example

Just include the Preview component close to the top component of your application (it places itself absolutely).

It is usable in two different ways: function-based and context-based. Both of them receive the same data formatted the same way, an object containing 3 properties:

  • itemType: the type of the item (monitor.getItemType())
  • item: the item (monitor.getItem())
  • style: an object representing the style (used for positioning), it should be passed to the style property of your preview component

The function needs to return something that React can render (React component, null, etc).

See also the examples for more information.

Hook-based

  import { usePreview } from 'react-dnd-preview';

  const MyPreview = () => {
    const {display, itemType, item, style} = usePreview();
    if (!display) {
      return null;
    }
    return <div class="item-list__item" style={style}>{itemType}</div>;
  };

  const App = () => {
    return (
      <DndProvider backend={MyBackend}>
        <ItemList />
        <MyPreview />
      </DndProvider>
    );
  };

Function-based

  import Preview from 'react-dnd-preview';

  const generatePreview = ({itemType, item, style}) => {
    return <div class="item-list__item" style={style}>{itemType}</div>;
  };

  class App extends React.Component {
    ...

    render() {
      return (
        <DndProvider backend={MyBackend}>
          <ItemList />
          <Preview generator={generatePreview} />
          // or
          <Preview>{generatePreview}</Preview>
        </DndProvider>
      );
    }
  }

Context-based

  import Preview, { Context } from 'react-dnd-preview';

  const MyPreview = () => {
    const {itemType, item, style} = useContext(Preview.Component);
    return <div class="item-list__item" style={style}>{itemType}</div>;
  };

  const App = () => {
    return (
      <DndProvider backend={MyBackend}>
        <ItemList />
        <Preview>
          <MyPreview />
          // or
          <Context.Consumer>
            {({itemType, item, style}) => <div class="item-list__item" style={style}>{itemType}</div>}
          </Context.Consumer>
        </Preview>
      </DndProvider>
    );
  };

Migrating

Migrating from 4.x.x

Starting with 5.0.0, react-dnd-preview will start passing its arguments packed in one argument, an object {itemType, item, style}, instead of 3 different arguments (itemType, item and style). This means that will need to change your generator function to receive arguments correctly.
