Bringing Pattern Matching To Typescript

Meetup teaser image

With the emergence and wide adoption of libraries such as React, Redux or XState, in the last few years the frontend ecosystem has shifted from an imperative to a declarative programming model. Now that we have realised how much easier it is to reason about declarative code and how many bugs are ruled out by embracing this paradigm, there is simply no going back.

Yet, Javascript and TypeScript weren’t designed for this paradigm, and these languages are lacking a very important piece of the puzzle: declarative code branching.

This talk will demonstrate how we can write conditional logic that is easy to read and maintain using ts-pattern, a Pattern Matching library for TypeScript.


Gabriel is a data visualisation software engineer @ Datadog passionate about application architecture, programming language design and colouring pixels.

Past Events

A hell of an icon

Using well known game avatars, Hendrik showed why using icon fonts could put you a bit more into icon hell when you want to have maximum flexibility in terms of positioning and theming. He demonstrated how SVGs combined with subtle animations give you a lot more creative options in combination with your text font and reduce visual noise in your user interface.

A hell of an icon / SVG, icon fonts, typography ...

Thanks for this session, Hendrik! And please checkout the list of SVG resources below to dig in deep into vector graphics on the web.

A blast from the past

Already 2 years ago Sebastian Golasch talked about exciting possibilities with the new Web USB API and which crazy things are possible when you actually can talk to your hardware via the browser. We think an update on the latest IoT ideas from him would be cool, what do you think? Also checkout his talk about WebRTC!
