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 🙏

react-online

Build passing Code coverage NPM package Code style: prettier Last commit License

A react component to declaratively check connection status. Uses isomorphic-is-online to work on Web, React Native and Node.

Installation

On your command-line terminal:

npm install --save react-online

Then in your code:

// Using ES6 modules with Babel or TypeScript
import Online from "react-online";

// Using CommonJS modules
const Online = require("react-online").default;

Usage

For example, in a web environment:

import Online from "react-online";

ReactDOM.render(
  <Online
    onChange={({ online }) => {
      if (online) {
        console.log("We can reach the internet, whoop whoop!");
      }
    }}
    render={({ online }) => (
      <div style={{ textAlign: "center" }}>
        <p>
          You can open up the devtools to simulate losing the network, or
          actually turn off your wifi to test things out.
        </p>
        <h1>{online ? "You are online." : "You are offline."}</h1>
      </div>
    )}
  />,
  DOM_NODE
);

Indeed, the Online component exposes a status object to represent connectivity so that you can act accordingly:

{
  online: boolean;
}

| Prop name | type | default | description | | --------- | ---- | ---------------- | ------------------------------------------------------------------------ | | onChange | func | (status) => {} | receives the latest status object, define some side effects | | render | func | (status) => null | receives the latest status object, returns the React component to render |
