Some people will tell you to test everything in your app. If you have time to kill, go for it. For most of us, we want to focus on tests that help us sleep at night. We'll be using jest in this guide, mostly because it provides snapshot testing.

This isn't something people normally test, but it saves us from typos that only show up in response to user interaction. Often we fail to dispatch all of the actions in our manual testing of UIs.

The premise here is simple, we want to know that all of our keys are actual functions. We'll be

Deploying a Production ready Django app on AWS

In this tutorial, I will be going over to how to deploy a Django app from start to finish using AWS and EC2. Recently, my partner Tu and I launched our app Hygge Homes (a vacation home rental app for searching and booking vacation homes based off Airbnb) and we wanted to share with other developers some of the lessons we learned along the way.

Following this tutorial, you will have an application that has:

• An AWS EC2 server configured to host your application
• SSL-certification with Certbot
• A custom domain name
• Continuous deployment with Github Actions/SSM Agent
