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

dnd-details

Takes a DragEvent object and returns information about the dropped content.

Installation

yarn add dnd-details

Resources

Usage

import dndDetails from 'dnd-details';

...

onDrop(event) {
    const details = dndDetails(event);
    console.log(details);
}

Returned object

The returned object has the shape

export interface IDropDetails {
    files: FileList;
    links: string[];
    images: string[];
    text: string;
    html: string;
}

Dragging from desktop

When files were dragged in from the local filesystem, the files list will be populated. None of the other values will be populated.

Dragging from other browser windows

When dragging content from other browser windows, the files list will always be empty, but several of the other values will be populated.

  • When a single link is dragged, text should contain the displayed text of the link, and links should have one entry with the href URL of the link
  • When a single image is dragged, images should have one entry with the src URL of the image
  • When a linked image is dragged, both links and images should be populated
  • When dragging in entire websites, e.g. Ctrl+A then drag and drop, you might have the data for many images and links
  • The links and images arrays will always exist, even if they're empty. So it's safe write code like if (details.images.length > 0) and you don't need if (details.images && details.images.length > 0)
