I am learning more about RxJS because I am mostly developing with Angular.

First of all, I found RxJS super interesting because it offers an alternative to promises. I never even thought there could be an alternative way to handle data! So that was cool.

Then, I realized I had no idea how to use RxJS in React! So I took a small detour to learn more about it. I ended up writing Use RxJS in React with Hooks.

I feel like RxJS is not really widespread outside Angular, despite being a JS library. Have you ever used it in React?

Focusing on picking up some of the classic books from the libraries nearby me to learn more about html/css, Javascript, etc. I definitely study/work better in quiet places so the library atmosphere helps with my concentration and focus.

Learnt about how bcrypt works. I always thought it was some obscure magic for password hashing.

Here's a cool article by Auth0 if any of you are interested: Understanding bcrypt

I learned that Sass is going to deprecate the @import rule. From the Sass docs, "The Sass team discourages the continued use of the @import rule. Sass will gradually phase it out over the next few years, and eventually remove it from the language entirely. Prefer the @use rule instead. (Note that only Dart Sass currently supports @use. Users of other implementations must use the @import rule instead.)."

I learned a lot about Event Processors in the Axon Framework. I did not know before they where that configureble, which can be nice when dealing with non-functional requirements.

This week I learn a bit more about node/express/mongoDB and made my own (simple) API.

Then I did a painful day with user authentication and with tokens. Something I will need to revisit.

Rest of the week I decided to look at Gatsby/Sanity and today I did my first Graphql query. i quite liked it!
