Good old AWS, the mercedes benz of cloud server hosts. I was at AWS today, and I got a better understanding of how to best run Ec2 servers to save in costs. ;)
Pro Tip: Use Async / Await With Act To Avoid Act Warnings in Jest / Enzyme Tests And Have Components Update Properly!
I was having a hard time recently writing jest + enzyme unit tests for a react.js project, and one of my colleagues saved the day with the await / async addition. In this post I'll go through what I was doing, what I tried that didn't work, and what we ultimately went with that fixed everything!
Although I am a huge fan of lambda functions and s3 + cloudfront deployment stacks, in this current project I was using the botkit framework to make a slack chatbot. The framework is awesome, but the only catch was that it needs to be actually deployed on a real server so I had to put on my sys admin hat and fire up some ec2's. I ran into an interesting challenge in that the botkit server wants to run on localhost:3000, but in order to run it securely I need to use port 443. After unsuccessfully trying a few simpler hacks I bit the bullet and chose to use nginx as a reverse proxy here. I hadn't had much hands-on experience with nginx before this project so it was definitely a learning experience for me, and this post will be basically a walkthrough of the things I did to get it up and running.
My team and I are working on a React project that runs in regular browsers, and we recently decided to use Cypress for end to end testing. It has an actually surprisingly nice you can use to write describe-it style test scripts that will load up a browser with any page on your site, click some things, interact with the dom, and then even do assertions that your page renders correctly. You can do "cypress run" to run your tests via the command line or "cypress open" to start this little application from which you can run all tests or just specific tests, and it creates this little sidebar that gives you a history of the commands it's running and details about what happened when things have failed. Anyway, yes Cypress is awesome, but that's not what thing blog post was supposed to be about...
I’ve been working as a software consultant for the past few weeks, and an interesting thing happened. The initial aggressive plan was to build a working prototype in 2 weeks that involved a React web front-end, Postgres db, and node backend api. Well, we wanted to not do a complete faceplant so we were kind of forced into cutting corners and optimizing for speed. For that reason and also since one of our three engineers was somewhat of a Ruby expert we thought it was be a quick win to quickly build out the backend api in ruby on rails. This post is me reflecting on my experiences today pair programming in Ruby on Rails.
