Week 2 Recaping Golang and building a CLI

Hey, this week was all fun.

I learned about Golang, how it works, what goroutines are, what mutexes are, what context is, and much more, including enums and coding practices.

Then I built a CLI using Golang to easily get AWS account details. It takes the credentials saved in your Linux machine and shows you what you need, like the cost explorer and EC2 details.

I faced problems understanding the Golang file structure and how structs are used to validate interfaces for plug-and-play databases. I built a web server that supports CRUD operations for students, which helped me understand the context and how everything works.

I also had trouble understanding what context is and how we use it.

I watched a video on context in Golang by Melkey on YouTube to grasp the basics. I also used ChatGPT to better understand and learn when to use context.TODO, context.Background, context.WithTimeout, etc.

Currently, I am using QuickDB as a project to learn more about Go and to strengthen my fundamentals. QuickDB is an in-memory database that uses the RESP protocol to communicate between the CLI and the server. It's quite nice.

Here are the links to the github project that I talked about

Special thanks to Savinder Puri for keeping me motivated and creating such great videos.

Here are the resources I used to review and learn about Golang:
MelkeyDev YouTube Channel
Hitesh Code Lab YouTube Channel
Coders Gyan YouTube Channel
ChatGPT
Stack Overflow

Will might write a blog to explain Golang context.

That's all from me. See you next week.

Thanks,
Yagya Goel
