Channeling Away Your PubSub CPU and Memory Usage

We were facing an escalating problem of memory usage that refused to be tamed through horizontal scaling. On closer examination, we discovered that the culprit was none other than our Redis PubSub system that manages multi-user editing, notifications and other websocket-based subscriptions via GraphQL Subscriptions. I'll take you through how

How to Decrypt Express-OpenID-Connect Session Cookies

I find cookies, sessions, encryption, OpenID and OIDC all very confusing.  I use the express-openid-connect library to handle our Auth0 integration and for the most part it takes care of all the difficult parts of OAuth, tokens, etc.  Eventually you need to peel back the curtain and adjust things. tl;

Apollo GraphQL, Request Logging with Pino

I love using pino for logging in NodeJS.  It's lightweight and provides all the normal logging stuff you'd expect.  It's verbose as hell, and you really need to be ingesting your logs somewhere, like DataDog. Lately I've been tripped up on linking errors to the originating requests.  We have a

Housekeeping before Hiring a VA

I've written about how to hire a VA [https://blog.dadops.co/2020/11/03/how-to-hire-a-va/].  If you don't already work with someone who manages parts of your life, it can be a bit chaotic.  There's a high chance that I have ADHD based on my family history, and my

Save $100/mo with custom domains on Vercel

I love the idea of review apps or pull request.  Where your code in a pull request is server live. I had recently changed the backend of our services to only issue cookies on our personal domain, let's call it myapp.com.  Since we were using Heroku and later Vercel

server

Servers, Requests, and Responses

If you are new to web development you probably hear terms like servers and requests bandied about. Server is probably the more confusing of the term since it gets conflated with physical hardware, i.e. computers sitting in data-centers. A server, in software-speak, is anything that serves requests at a

These days everyone is a "full stack" developer, but what is a full stack? The purple might be your cloud service provider, and the yellow is the code in your web browser."Stack" refers to how we think of the various software layers.  The term is fuzzy and if you

Routing HTTP Requests

OG Routing With a static HTML site (and the first incarnation of my personal website) you had a file structure like this: mywebsite/ index.html favicon.ico 2021/ why-i-like-she-ra.html And you would run a webserver, or host this somewhere like Netlify that would serve index.html if someone requested

Hallmarks of a good API

Copy the current URL to the clipboard in a React app

Interacting with the clipboard used to be hard as there weren't a lot of great browser APIs.  That's changed now.  Here's how to copy the URL of the current page using React.  You don't really need to use React, but I did. The basic premise is this: 1. Create a

Connecting Github Actions across Repositories

I am a fan of small niche single purpose tools.  I was building a landing page for a web site and I wanted a screenshot of a text message. iFake Text Message [https://ifaketextmessage.com] is a simple tool that handles this well.  It's very iMessage-centric.  It let's you customize

Git and Historical Revision

A well crafted history is a trade off. It's similar to writing tests. Most of the time tests do nothing, but when they raise an alarm it is super handy. With practice, the cost is minimal.

The Purpose of Version Control

I think it's rare to see a project not automatically added to Github shortly after, if not before, inception.  It's just a checkbox of writing code.  Previously it was something to think about.Github [https://github.com] (and Bitbucket [http://bitbucket.org], Gitlab [https://gitlab.com/], etc) make it supremely
