Go - The Ultimate Folder Structure

Organizing your Go (Golang) project's folder structure can help improve code readability, maintainability, and scalability. While there is no one-size-fits-all structure, here's a common folder structure for a Go project:

project-root/
    ├── cmd/
    │   ├── your-app-name/
    │   │   ├── main.go         # Application entry point
    │   │   └── ...             # Other application-specific files

Basic definitions

• String s matches the regex pattern /p/ whenever s contains the pattern 'p'.
  • Example: abc matches /a/, /b/, /c/
• For simplicity, we will use the matches verb loosely in a sense that
  • a string can match a regex (e.g. 'a' matches /a/)
  • a regex can match a string (e.g. /a/ matches 'a')
• A regex pattern consists of literal characters that match itself, and metasyntax characters
• Literal characters can be concatenated in a regular expression. String s matches /ab/ if there is an a character *directly followed by a b character.
• Example: abc matches /ab/, /bc/, /abc/

Windows Preparation

1. Ensure hypervisor functionality is enabled in BIOS.

   • I know it sounds stupid, but if you already have it enabled, disable it, restart the machine, and enable it again.
   • Otherwise you will hit microsoft/WSL#5363

2. Launch a PowerShell prompt in Administrator mode [Win+X > Windows PowerShell (Admin)]

dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart

ARN Base Pattern :-

arn:<aws_parition>:<aws_service>:[<aws_region>]:<account_id>:<root | resource_type>:/<resource_name>[/<sub_resource_names>...]

i. <aws_partition>
Regex - (aws|aws-us-gov|aws-cn)

ii. <aws_service> - No fixed pattern
iii. <aws_region> - No fixed pattern
Most of the regions occur in combination of 2 letter followed by "-" followed by a combination of direction based word , followed by a "-" and then a digit.
