Lessons from Maintaining TypeScript Libraries

Maintaining widely-used JS libraries is already complicated, and TypeScript adds an additional set of challenges.

Join Redux maintainer Mark Erikson for a look at some of the unique problems TS library maintainers face, and how the Redux team has handled those problems. We'll cover:

  • Tradeoffs of different ways to define TS types for a library;
  • How to target different versions of TS, and considerations for determining the supported version range;
  • Migrating existing JS libraries to TS;
  • Differences between writing ""app"" types and ""library"" types;
  • Managing and versioning public types APIs;
  • Tips and tricks used by types from the Redux libraries;
  • TS limitations and possible language-level improvements.

Plug-in architecture: how TypeScript let us paint-by-numbers

Adding a new feature to an unfamiliar codebase can be painfully slow. What if you could lean on TypeScript to guide you?

At Snyk plugin architecture is a common pattern to extend language support across different products and codebases. Adding TypeScript to the mix has allowed us to add new features quickly and it can be as simple as painting by numbers when it comes to extending the code.

Join me as we create a simple library using plugin architecture and follow the trail of TypeScript hints to add a new feature.

TypeScript for Library Authors: Harnessing the Power of TypeScript for DX

Using real-life open-source examples, we'll explore the power of TypeScript to improve your users' experience. We'll cover best practices for library authors, as well as tips and tricks for how to take a library to the next level.

This talk will cover:

  • how to leverage the type inference to provide help to your users;
  • using types to reduce the need and complexity of your documentation - for example, using function overloads, string literal types, and helper (no-op) functions;
  • setting up testing to ensure your library works (and your types do too!) with tools like tsd and expect-type;
  • treating types as an API and reducing breaking changes whilst shipping enhancements;
  • I'd draw on my experience with libraries like nuxt3, sanity-typed-queries and typed-vuex and show what we managed to do and what I'd do differently in future.

Understanding types as sets

Get an in-depth understanding of what types represent in TypeScript, how basic set operations apply to them, and learn how to use them to your advantage through some practical examples.

Deno Land Inc., Netherlands
Writing universal modules for Deno, Node, and the browser

This talk will walk you through writing a module in TypeScript that can be consumed by users of Deno, Node, and browsers. I will walk through how to set up formatting, linting, and testing in Deno, and then how to publish your module to deno.land/x and npm. I will also start out with a quick introduction on what Deno is.

Onboarding React Developers to Typescript

Your team has just hired a React Developer to work on your Typescript codebase. Both your team and the new engineer are eager to start building features, but they only have experience writing Javascript. How can you quickly onboard the engineer to Typescript while still providing them with time and space needed to learn the language effectively? In this talk, we’ll discuss why Typescript fundamentals, like function types, interfaces, and generics, can be intimidating for learners. Then, we’ll walk through successful, practical approaches for teaching each of these concepts and relating them back to React. By the end of this talk, you’ll have the building blocks for creating a fruitful onboarding session for your engineers.

TypeScript and the Database: Who Owns the Types?

We all love writing types in TypeScript, but we often find ourselves having to write types in another language as well: SQL. This talk will present the choose-your-own-adventure story that you face when combining TypeScript and SQL and will walk you through the tradeoffs between the various options. Combined poorly, TypeScript and SQL can be duplicative and a source of headaches, but done well they can complement one another by addressing each other's weaknesses.

Alternatives to TypeScript - Ashley Claymore

While TypeScript is currently the most popular static type checker for JavaScript, there are alternatives. In this talk, we'll look at Flow.js and Hegel, and review the similarities and differences among the three. Doing this will put TypeScript in perspective, and maybe help explain why the TS team made certain design decisions.

How to properly handle URL slug changes in Next.js - Ondrej Polesny

If you're using a headless CMS for storing content, you also work with URL slugs, the last parts of any URL. The problem is, content editors are able to freely change the slugs which can cause 404 errors, lost page ranks, broken links, and in the end confused visitors on your site. In this talk, I will present a solution for keeping a history of URL slugs in the CMS and explain how to implement a proper redirect mechanism (using TypeScript!) for dynamically generated pages on a Next.js website.

Type Safety at Runtime in Typescript - Kajetan ŚwiΔ…tek

We all know, that TypeScript helps us in many ways. The compiler guides us during our work, ensuring, that every piece of data falls into a given place.

But there are some limitations. TypeScript was meant to help us during development time. After the compilation step, we still cannot be 100% sure what can happen during runtime...

Unless we do something about that and defend ourselves against unwanted runtime errors! This talk serves as an introduction to the problem and explains how we can face it to make our applications more error-proof.
