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-native-vpn-detect

A React Native wrapper to determine if the current iOS network connection is on a VPN (NetInfo supplies this for Android).

Installation

npm i --save react-native-vpn-detect # npm syntax
yarn add react-native-vpn-detect # yarn syntax

then enter the ios directory and run pod install to link the pod to your React Native project.

Usage

Import the library along with the NativeEventEmitter exported from React Native:

import { ..., NativeEventEmitter } from "react-native";
import RNVPNDetect from "react-native-vpn-detect";

Setup:

in componentDidMount, instantiate a new NativeEventEmitter, passing in RNVPNDetect.

const RNVPNDetectEmitter = new NativeEventEmitter(RNVPNDetect);

Then, add a listener to the EventEmitter instance, and make sure to store it somewhere globally available on the component (e.g. instance variable) so you can unsubscribe from it later.

The listener should take: "RNVPNDetect.vpnStateDidChange" as the event name to listen to, and a handler of your choosing as the second argument.

RootContainer._iosVpnDetectSubscribe = RNVPNDetectEmitter.addListener(
  "RNVPNDetect.vpnStateDidChange",
  this._handleVpnStateChanged
);

RNVPNDetect can be used in two ways:

  • Using a timer, which will check for a change in the VPN state at the provided interval, and send an event IF the state has changed
  • Manually asking for the current vpn state

Use Timer

After following the setup steps above:

You can then initialize the timer with an interval of your choosing. It defaults to 3s (3000ms) if nothing is passed in.

RNVPNDetect.startTimer(5000)

Make sure to unsubscribe from the listener when your component unmounts.

componentDidUnmount {
  ...
  if (RootContainer._iosVpnDetectSubscribe) {
    RootContainer._iosVpnDetectSubscribe.remove();
    RootContainer._iosVpnDetectSubscribe = null;
    RNVPNDetect.stopTimer();
  }
}

Manual

After following the steps above, you can manually query the current vpn state by calling:

RNVPNDetect.checkIsVpnConnected()

This will check the current vpn state and trigger the listener you set up in componentDidMount.

You should still unsubscribe from the listener on unmount, but you can skip the stopTimer call if you never started one ;)

componentDidUnmount {
  ...
  if (RootContainer._iosVpnDetectSubscribe) {
    RootContainer._iosVpnDetectSubscribe.remove();
    RootContainer._iosVpnDetectSubscribe = null;
  }
}
