Paris Typescript

On se retrouve pour le troisième meetup de l'année qui aura lieu online sur YouTube. Comme nous accueillons des speakers internationaux, ce meetup sera intégralement en anglais.

We meet again for the third meetup of the year that will be online on YouTube. As we welcome international speakers, this meetup will be in english.

Programme :

• Talk #1 : Implementing Complex Design Systems

Auteur : Andrey Soloviev (Aircall)

Durée : 20 min

Description :

As companies work on features and evolve their product, design systems become increasingly used and front-end engineers find themselves working with atomic components more and more. Our goal is to make our front-end components into our single source of truth, instead of the sketch files, and we'd like to share a few thoughts on how we're going about it.

• Talk #2 : Combining Type Systems with TS and GraphQL

Auteur : Roy Derks

Durée : 30 min

Description :

Having typed code is the major reason for developers to work with TypeScript. Most npm packages offer TypeScript typings, but usually your data doesn’t. When you’re using GraphQL as your datalayer, you can combine its own type system with TypeScript to maintain end-to-end type safety. In this talk I’ll show how you can use GraphQL to save you time and effort when creating your servers and applications.

• Talk #3 : TBD

Auteur : TBD

Durée : TBD

👨🏻🇫🇷Nicolas DUBIEN: Property-based testing: from zero to hero

Property based testing has been introduced by QuickCheck in Haskell years ago. It is a pretty well known technic to test apps in the functional world. Nonetheless, it is still pretty unknown outside of the functional world.

This talk will introduce the benefits that property based testing can have to increase the confidence you have in your tests. This new tool will make you able to detect unexpected bugs earlier and easily in various kinds of problems: from algorithms to ui interfaces.

Examples shown during the talk will be written using fast-check, a property based testing framework written in TypeScript that already discovered bugs in some huge libraries of the JavaScript ecosystem (eg.: Jest, Jasmine). But everything can be easily adapted to other frameworks in other languages.

About Nicolas:

Frontend software engineer for a start-up called Pigment launched in September 2019 and based in Paris. I am mostly working in TypeScript to build a React app - and sometimes a bit of C#.

Before that I have been working in C++ for 3yrs, then C# and TypeScript to build an Angular app for 2yrs.

Outside of the work, I am the author and maintainer of fast-check. I did multiple talks about it and proved it useful to detect bugs in many huge libraries so I really believe it can help the whole community.

👨🏻🇺🇸Robbie Ostrow: Taking Types Too Far: Checking the Collatz Conjecture at Compile Time

This talk is based on a blog post I wrote back in December: https://ostro.ws/2019...

This talk will build up Peano Arithmetic from scratch within the Typescript type system, where we use our newfound power to check the Collatz conjecture (well, at least for really short chains.) No prior number theory experience is required. Runtime side-effects are strictly forbidden.

If there's interest, I may also discuss using the same ideas while writing https://github.com/os...

Now that I'm under quarantine, I figured it would be nice to give a remote talk!

About Robbie:

I'm a software engineer sheltering-in-place in San Francisco. I work for a startup called Vanta and occasionally like to abuse tools to solve tasks that they have no business solving.

Phoenix TypeScript

We will have our first Phoenix TypeScript meetup event on June 9th. Feedback was roughly 50:50 on whether we should run it over lunch or dinner, so we'll do both. The plan is that we'll record short talks and have a live chat during the event. It will take place at both 12pm and 7pm on the day of the event, unless everyone ends up preferring one time over the other. :)

Also, we encourage you to attend HalfStack Online on May 22nd. It's a creative JS/TS+web celebration and covid-19 charity fundraiser. Tickets are just $19. https://halfstackconf... has more details.
