TypeScript, Open Source and the Government: the birth of IO.italia.it

I'll talk about what is probably one of the biggest open source projects written entirely in TypeScript: IO.italia.it, an app and a platform API that helps people interact with the national and local Government.

We started working on IO at the beginning of 2017, in two and half years we've written almost 60K lines (and counting) of TypeScript code between the mobile app (React Native) and the backend (Express and Azure Functions). I'll talk about the history of the project, the technical and architectural choices we made, the libraries and the tools we use and we contributed to the community and how TypeScript helps us to write better, more solid and more secure code.
Federico Feroldi

I've written my first web app a little more than 20 years ago (in Perl) and since then I've never stopped enjoying building digital products.
I've worked for small startups, big megacorporates and I've also co-founded a few startups, giving me the chance to live and work in Italy, UK, US and Germany and have the opportunity to work with quality teams and exceptional people.
I love writing as much as reading other people's code, if you'd like a feedback just send me a code review request on github :)

Migrating large codebase to TypeScript

As a growing startup with large JavaScript codebase we’ve made the transition to TypeScript and survived to tell the tale! It wasn’t easy to make the decision but only half year later we feel like the investment already paid off. We looked back and identified many Dos and Don’ts to talk about.

It’s 2019 and TypeScript is the obvious choice for every new project. But if your codebase is JavaScript how do you make the switch? Facing a quarter million lines of code – a messy mixture of untyped or poorly flow-typed JavaScript – our team of 15 at productboard absolutely knew we wanted to make the switch, but the barrier to entry looked very high. A half a year later, 85% of the codebase is strictly typed TypeScript and our confidence over the code has increased tremendously. In this talk I’d like to share our experience and answer the following questions:
  • How we convinced management it was worth the effort?
  • How we approached the migration and how we phase it?
  • How we learned to best collaborate as a team?
  • What we’d do differently next time?
  • We learned a lot along the way and are eager to share it with all the other teams, because we believe everyone deserves TypeScript!

"I am Frontend developer at productboard, helping various companies around the globe with building better products. As a developer I always try to go one step further towards excellence. The best feeling is when even my designer is surprised about the result. I like delightful UIs and my most favourite interaction is Drag and Drop."

Full-stack type safety with TypeScript and io-ts

Ever wondered what going full-stack TypeScript means for your day-to-day workflow? In this talk we’ll see how to exploit the TS type system and the io-ts library to provide a “full-stack type-safe” development experience for a project comprising a Node.js HTTP API and a single page web application.

In this talk we’ll see how developing on the same language and technologies full-stack can lead to a smooth developer experience with strong assurances of correctness at build-time. I’ll present the awesome io-ts library by Giulio Canti and a few key concepts of the TS type-system, and we’ll build upon these to live-code a custom solution to meet our needs. We’ll also briefly discuss other related topics, such as JSON (de)serialization and API error handling, and compare what we obtained with other available solutions.

Fall in Love With TS Decorators

Decorators is one of the most underrated features in TS. At the same time is one of the most life changing features. Once you get it your, life will never be the same. We will start from basics definitions and go all the way to advanced real life examples and use cases.

Decorators are incredibly cool. They allow you to describe meta data directly in the class declaration, grouping everything in one place and avoiding duplication. Terribly addictive. Once having tried, you will use it forever However the decorators in TypeScript are not as simple as we would like. Working with them requires some skills.
In this talk we will try to cover:
  • Prologue
    • Decorators in TC39 stage 2. meaning and when to expect.
    • Babel
    • Frameworks uses decorators (Angular, NestJS, MobiX…)
  • Intro
    • Descriptor and why it’s matter
    • Simple logger decorator (livecoding)
  • Method decorator
    • Run time
    • Validators (livecoding)
    • memoize (livecoding)
  • Method’s param decorator
    • Why it’s so cool
    • Real life examples (livecoding)
  • Class Decorators (livecoding)
    • Class Composition
    • Class mixing
  • Advances (optionally)
    • Reflection, metadata
    • Use cases and examples (livecoding)
  • A coding is worth a thousand words….
