30-day Learning Challenge: Day 2— Learning AWS S3

Welcome back to the learning challenge that I’ve set out for myself, where I aim to document something new that I’ve learnt every single day for 30 days!

Today, I decided to take a short break from learning Figma from my day 1 adventures, and have engaged in some work on AWS.

For my tasks today:

• Work with uploaded files in an S3 bucket that would then be utilised in a script that I had written on my local machine few weeks prior.
• Learn how to implement S3 bucket object creation triggers for my Lambda functions. Overall, an exciting day!

This was my first time experimenting with accessing S3 via Javascript, and I had quite a bit of looking up to do. After searching online, and going down the dreaded rabbit hole of AWS documentation, I finally got it to work through the use of the AWS SDK, and the folks over on StackOverflow (thanks guys).

In the upcoming days, weeks and months, I hope to get even more comfortable with AWS and the different services it provides. Personally, after experimenting with different learning methods, I find that knowledge still sticks the best through trying our hand and attempting a practical. Nothing beats practicing the skill by actually utilising it for your code, work or internship, as there’s only so much know-how you can gain from purely reading about what AWS provides.

Drop a comment if you’d like to hop on a similar journey, and feel free to share with me what your goals are and who knows, we could get started on something together in the foreseeable future!

Have a great day ahead!
