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 🙏

Published

Allow authentication to take place entirely in the client, avoiding the need for a server component. This is a security risk but may have some valid use cases or be useful when getting started.

pusher-js Client Authentication Plugin

Pusher is built with security in mind. Because of this you need to authenticate subscriptions to private- and presence- channels against a server. However, sometimes you don't want to do this. This plugin provides a way of authenticating on the client (in the browser).

However, you SHOULD NOT expose your application secret in production. If you have a real production use case for this then please drop me an email.

Prerequisites

This is a plugin for the official Pusher JavaScript library and compatible with the latest 2.2.x release. Make sure you have a working implementation up and running.

Documentation and configuration options are explained at the Pusher-js Github page

Usage

Load the plugin after including the Pusher library

<script src="//js.pusher.com/2.2/pusher.min.js"></script>
<script src="dist/pusher-js-client-auth.js"></script>

Configuration

This plugin comes with a few extra configuration parameters. The whole list is available at the Pusher-js Github page

var pusher = new Pusher(APP_KEY, {
    authTransport: 'client',
    clientAuth: {
      key: APP_KEY,
      secret: APP_SECRET,
      user_id: USER_ID,
      user_info: {}
    }
});

clientAuth.key (String)

Required field. This is duplicating the APP_KEY. However, there is no nice way of fetching the value through the existing API so duplication seems to be the best option for now.

clientAuth.secret (String)

Required field. This is your application secret. Remember: do not deploy this to production.

user_id (String)

The user_id used when authenticating Presence channels. This user id will be used to uniquely identify the user.

user_info (Object)

The user_info used when authenticating Presence channels. The information supplied here will be available to anybody subscribed to the presence channel.

var pusher = new Pusher(APP_KEY, {
    authTransport: 'client',
    clientAuth: {
      key: APP_KEY
      secret: APP_SECRET,
      user_id: 'leggetter',
      user_info: {
        twitter: 'leggetter'
        github: 'leggetter'
        bio: 'Developer Evangelist'
      }
    }
});
