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-connection-info

travis build version downloads MIT license github

Higher order component for React Native to detect network connection state.

Use withConnection to inject the connection object which currently has the isConnected property. This is a boolean value that indicates internet connectivity status (see the NetInfo documentation on isConnected).

Usage

Installation

npm install --save react-native-connection-info

Android

Make sure to also include permissions on Android. Add the following line to your AndroidManifest.xml

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

Examples

import React from 'react';
import {
  Text,
  View,
} from 'react-native';
import { withConnection, connectionShape } from 'react-native-connection-info';

const MyComponent = ({ connection }) => (
  <View>
    <Text
      style={{ color: connection.isConnected ? 'lightskyblue' : 'lightcoral' }}
    >
      {connection.isConnected ? 'Connected' : 'Offline'}
    </Text>
  </View>
)

MyComponent.propTypes = {
  connection: connectionShape,
};

export default withConnection(MyComponent);

Redux Wrapped Instance

Usage with redux is supported by default.

This section is only used if you need to reference the wrapped instance using getWrappedInstance() when using react-redux's connect(). This component uses { withRef: true }.

Usage

// instead of importing from 'react-native-connection-info'
// import { withConnection, connectionShape } from 'react-native-connection-info';
// just add /redux
import { withConnection, connectionShape } from 'react-native-connection-info/redux';

The rest is the same as in the first example.
