This Week in Effect - 2024-02-09

Feb 9th, 2024

Hi Effecters!

Welcome back to This Week In Effect (TWIE), our weekly update that aims to help you keep track of everything that is going on inside our Community and the Effect Ecosystem.

If it’s your first time here, Effect is a powerful TypeScript library designed to help developers create complex, synchronous, and asynchronous programs. One of the key features that sets Effect apart is how it leverages structured concurrency to provide features such as async cancellation and safe resource management, making it easier to build robust, scalable, and efficient programs.

To get started, below you’ll find our quick-start guide and documentation that will be your first step in your Effect journey. Enjoy!

Overview of TWIE

Another week has passed, and we're on our second date with TWIE. Since some of you may have missed the last post, we would like to spend a few words on what TWIE is and what it aims for.

We’re happy to witness the community growing so fast, with more and more people adopting Effect, and we understand that it might not be that easy keeping up with everything that is going on in the Effect Ecosystem:

  • Our Discord server reached 1850+ members a few days ago and the engagement is at an all-time high.
  • We’re approaching our very first Effect Days Conference in Vienna on February 23, 2024, and lots of new content is coming up.
  • All projects around Effect are receiving key updates and there has been a lot of activity on GitHub.

So, we wanted to make it easy for you to find all the info you need to fully enjoy your Effect journey!

And, that’s why we created TWIE – a weekly update to inform you about key events about Effect in the previous week, both from the community (Discord discussions, X posts, YouTube content, etc.) and from a technical standpoint.

In this way, we want to help you stay on track with everything happening in the Effect Ecosystem and actively engage with our community.

Now, back to business!

Effect Days Update

As you may already know, our big event in Vienna is getting closer and closer. From the 22nd to the 24th of February, we'll have the opportunity to meet our amazing community and unfold what the future of Effect will be.

There are only 3 workshop tickets left, and if you're still sitting on the fence, that's your last chance to get one!

For those of you who may have missed it, here's our full speaker lineup.
