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 🙏

About

The best way to check the internet status on the user's device.

This library makes it possible to check the connection status of the user's device in real-time, whenever the connection undergoes any change, it is verified, if this change means a loss of connection or the availability of connection, an event is triggered with the current connection status of the device.

  useEffect(() => {
    (async () => {
      //Start listener
      await NetworkListener.startListener();
        
      //Set callback for changes in network status 
      NetworkListener.onNetworkStateChange((status) => {
        console.log("+===STATUS: ", status);
        setNetworkStatus(status);
      })
    })();
    
    //Remove listener when app destroy
    return () => NetworkListener.stopListener();
  }, []);

  return (
      <SafeAreaView style={styles.sectionContainer}>
          <Text style={styles.sectionTitle}>Network Status:</Text>
          {networkStatus && <Text style={styles.sectionTitle}>Connected</Text>}
