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 🙏

Features

✓ returns a promise  
✓ invokes "noCredentials", if username or password is empty  
✓ invokes "notFound", if user not found by usesername
✓ invokes "isDeactivated", if user is deactivated
✓ invokes "toDeactivate" for HUMAN users, if last login and user's creation long time ago
✓ invokes "loginExpired" for HUMAN users, if last login is some hours ago
✓ invokes "invalidPassword" if active user exists, but passwort is wrong
✓ invokes "invalidWebToken", if JsonWebToken is there (not falsy) and invalid
✓ invokes "authenticated", if active user found and passwort is ok
✓ invokes "authenticated", if valid JsonWebToken is there
✓ invokes "notFound", if user not found by JsonWebToken
✓ invokes "invalidWebToken" by list of JsonWebTokens (jwtList)
✓ invokes "notFound", if last token is valid, but user not found (jwtList)
✓ invokes "authenticated" by jwtList (last entry will be checked first)
✓ invokes "authenticated" by jwtList (both entries will be checked if last one is invalid)
✓ invokes "oldPwUsed" (oldPasswordUsed), if secondary password is given, but old password is used (and does match) to authenticate
✓ supports login with secondary password, if configured
✓ invokes "toDeactivate", if active, non system user reach max attempts with wrong password, within some time-frame
✓ invokes "passwordExpired", if active, non system user login with old password
✓ supports login with temporary password
✓ must not invoke "toDeactivate", "loginExpired" and "passwordExpired" for SYSTEM user

Arguments

The argument object consists of

arg = {gofer, carrier, lib, jwt, jwtList, username, password}

Gofers are callback functions which will be invoked with "user" argument.
Carriers are Promises to load/send data.
Libs are functions or promises to map data.
jwt is optional JsonWebToken string, encoded as it comes from request data.
username/password is required, if jwt is falsy or invalid.
jwtList (array of string): with this argument, potential existence of more than one token (e.g. due to usage of cross-domain cookies) is supported. According to standard's recommendations how browsers send duplicate cookies, last item will be checked first. If jwtList is given, jwt is ignored.

gofer = {
	noCredentials(){},
	notFound(){},
	isDeactivated(){},
	toDeactivate(){},
	loginExpired(){},
	invalidPassword(){},
	authenticated(){},
	oldPwUsed(){},
	passwordExpired(){}
},
carrier = {
	getUser: ({username}) => <Promise resolve to user or null>

lib = { comparePassword: (x, y) => <Promise resolve to boolean> }
