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

Adding "Copy" (to Clipboard) Button

If you would like to add a button to your fenced code blocks so that users may copy the code, you can do so in Docusaurus. You will have to add some code to your Docusaurus project, as seen below.

Under static/js, create a file called code-block-buttons.js with the following:

// Turn off ESLint for this file because it's sent down to users as-is.
/* eslint-disable */
window.addEventListener('load', function() {

This is the example usage of electron-packager that I never found online anywhere else.

To add resource.exe and resource2.dll in the resource folder when you create an installer, this is how you do it with the --extra-resource commandline switch.

--extra-resource

electron-packager . --overwrite --asar --extra-resource="resource1.exe" --extra-resource="resource2.dll" --platform=win32 --arch=ia32 --icon=./frontend/dist/assets/icon.ico --prune=true --out=./build --version-string.ProductName='Hot Pan de sal'

within the backend code you can refer to the files as:
