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 🙏

redis.auth

A non prescriptive Redis Authentication module for Express

By Chris Cates :star:

Installation

npm install redis.auth --save

Configuration

Note that it requires redis.token npm module to work properly

var redis = require("redis.token")()
var auth = require("redis.auth")(redis, {
  //Check for which Express header use when authenticating the client
  "header": "authorization",
  //The key in the redis session storage you want to check for
  "key": "grantType",
  //If return error is true it sends a 403 or 500 status based on the error
  //Turn this off if you want to do your own error checking
  "returnError": true
})

Example Express middleware

var express = require("express")
var app = express()

var auth = require("redis.auth")()

//Example single user permission
app.get("/user", auth("user"), function(req,res) {
  //req.auth = stored Redis.Token Object
  return res.status(200).send("Only users can access this...")
})

//Example multi user permission
app.get("/user", auth(["user", "admin"]), function(req,res) {
  //req.auth = stored Redis.Token Object 
  return res.status(200).send("Admins and users can access this...")
})

/*
** Assuming the following is in the redis token
** { grantType: user }
** And the header has a valid Redis token...
*/

Example status returns:

With returnError = true

return res.status(403).send({
  "error": true,
  "status": 403,
  "message": "No "+config.header+" header supplied..."
})

With returnError = false

//Sets these variables in req so you can check for them on your own
req.error = true
req.errorType = "No "+config.header+" header supplied..."
req.errorCode = 403
return next()
