Purpose

The purpose of the following gist is to allow me (and interested readers) to level up our backend knowledge to design, implement and maintain Pub/Sub services in Node.js using Kafka as the message bus.

I'll be documenting my journey and learning here.

Tech stack to explore

• Javascript
• Typescript
• Node.js

This could be a problem cause by your Windows OS being a bottleneck and limit your speed. After some talks and discussion with a colleague, this is the solution that worked for my case!

From Windows

The Foundation has been here for years and has been crucial to help F# become what it is now. So now, we're seeing that the F# community has taken flight and things never seemed better. We have the great things happening like the ever-successful mentorship program that attracts several developers each round. Now comes the time to re-think what can the Foundation to help and support its community in ways that we didn't try better.

TL~DR

I want to promote F# developers and education initiatives as much as I can.

• Let's help create, maintain and support courses in F# in high school and in STEM programs,
• Let's plan more events so that we can continue spreading the good word on F#. Still in 2021, when I say F#, I can hear developers being unaware of what it is or being confused about what can be achieved with F#
• I'd like to find a way around the limitations of Foundation to help support the F# projects that have the most traction,
• We lack representation in Microsoft docs. We usually see a lot of C# and

Some of the books I'll be recommending are based on .NET. Do not be discouraged. We shouldn't strive to stick to a specific technology stack. Your ambitions and goals will evolve over time and that might lead you a completely new space. Moreover, there are lessons to be learned from an environment that's different from what you're used to.
