Today's Talk explores the world of TypeScript ecosystem tooling, discussing essential tools for project setup, including package managers and project scaffolding. It also covers code analysis, testing, and deployment in TypeScript, as well as best practices for maintaining high-quality code. The Talk emphasizes the importance of intelligent code editors, code formatters, and linters in ensuring code quality. It also highlights the significance of codebase maintainability and following TypeScript best practices for efficient and scalable code.

Today's Talk focused on the importance of TypeScript in preventing runtime errors and its integration with popular frameworks like Vue.js, Angular, and React. TypeScript provides error assistance and typing boundaries between components, ensuring correct usage. It also allows for the creation of generic components, leveraging TypeScript generics to define contracts between unknown properties. The Talk highlighted the use of TypeScript in various scenarios, such as working with React Node, and provided resources for further learning and exploration.

This Talk is about implementing a limited subset of the type equivalent of React, specifically its JSX engine, in the TypeScript type system with no runtime code. The speaker demonstrates how to use TypeScript features like constrained types and template literal strings to infer and render JSX elements in the type system. They also show how to render headings and children using a utility called 'render component'. The Talk concludes with additional resources for learning TypeScript and related topics.

This Talk explores static analysis tooling for JavaScript and TypeScript, focusing on detecting bugs with TypeScript and ESLint. The importance of type checking and extending recommended rules is emphasized. The Talk also delves into specific ESLint rules and provides code samples to demonstrate their usage. The insights provided by ESLint powered by TypeScript are highlighted. Floating promises and misused promises are discussed, along with recommendations for handling exceptions and resources. The Talk concludes by offering resources and support for further exploration and development.

TypeScript's influence in the JavaScript ecosystem and its alignment with JavaScript's goals and principles. TypeScript's impact on the industry and its popularity among JavaScript programmers. The goal of TypeScript to innovate in types without introducing new concepts to JavaScript. The challenges of running TypeScript on other people's code and making it a native browser language. TypeScript's compatibility with JavaScript and its aim to be a thin layer on top of JavaScript. The efforts to improve support for JS and JS docs and the pain points of transitioning to TypeScript. The accessibility work in TypeScript and the absence of real competitors in the market.

The Talk discusses the limitations of TypeScript and the lies we tell ourselves about its type safety. It explores examples of unsafe operations and bending the type system using keywords like type assertion and function is dice. The Talk also covers catching syntax errors, type mismatches, and the complexity of conditional types and generics. It emphasizes the importance of understanding TypeScript's limitations and making well-informed decisions as software engineers.

TypeScript for library authors offers benefits for both internal and external use, improving code quality and providing accurate understanding of libraries. Documentation and examples should be in code to provide up-to-date information. Testing types alongside unit tests ensures accurate typing. Managing changes and exposing types requires careful versioning. Deep integration of types improves usability. Using a map in TypeScript allows for simpler implementation and customization. Leveraging types in libraries can generate code based on user access. TypeScript integration with Nuxt provides support and type declarations.

Today's Talk highlights the importance of software quality and its impact on businesses. It emphasizes the use of different tools and practices to improve software quality. The Talk covers topics such as testing with TypeScript and React Testing Library, accessibility, Cypress for end-to-end testing, writing better queries, monitoring performance, using feature flags with LaunchDarkly, and the value of Prettier. The key takeaway is that developing high-quality software with fast feedback loops and simplicity is crucial for success.

This Talk explores the use of TypeScript, 3JS, hand recognition, and TensorFlow.js to create 3D experiences on the web. It covers topics such as rendering 3D objects, adding lights and objects, hand tracking, and creating interactive gestures. The speaker demonstrates how to build a cube and a bouncy box, move objects with flick gestures, and create a solar system with stars and planets. The Talk also discusses the possibilities of using hand gestures for web navigation and controlling websites, as well as the performance limits of these technologies.

Hi, everyone. Today, I'll be showing you some of the features that modern frameworks implement or frameworks that leverage Typescript implement to improve the developer and user experience. I'll cover some of the features that Expo with Expo Router and Next.js with the AppRouter implements. Let's talk about setting up TypeScript in both Expo and Next.js. Both frameworks provide a TypeScript-first development experience. The most important feature is type safe routing, which enhances developer productivity and app stability. Frameworks provide a built-in link component for link generation. It reduces the risk of typos and throws type errors when linking to non-existent routes. In Expo, enable the .typed experiment and import the link component from the exporouter package. Expo supports static and dynamic routes, and throws errors for incorrect parameters. ExpoRouter provides hooks like UseSegments and UseRouter for more control. In Next.js, enable typedRoutes in the next config file. We can import the link component from the next link package and restart the dev server after updating the next config file. Next.js automatically generates route definitions and includes the type file in the TS config. Autocompletion is available for the href attribute, which can be a string or dynamic value. Next.js provides hooks like use router for static navigation and router.push to prevent redirection to broken routes. Catch all routes in type safe routing pose a challenge for enforcing type safety on the href attribute. TypeScript may not throw an error for routes that may be broken or lead to unwanted pages. Keep this in mind when working with catch all routes. Before a production build, route types should be in place to ensure accurate type definitions. Generating routes is an ongoing task that needs to happen at the right moment to avoid build-time errors. When implemented correctly, type-safe routes can elevate the developer experience by preventing broken links or dysfunctional routes. In Next.js, server components and client components have different limitations. Next.js provides automatic error checking for importing useState in server components and enforces the useClientDirective to prevent using client-related code in the wrong places. Next.js also ensures type safety by throwing errors for invalid segment config options and requiring the alt attribute for image components to improve accessibility. Config files in Expo and Next.js have different approaches to incorporating TypeScript, with Expo using the TS node require hook and Next.js supporting type checking through jsdoc in the config JS file. By enabling type-safe routing, we catch potential issues at compile time, ensuring robust routes and unbroken links. Many other frameworks and tools leverage TypeScript to empower developers and deliver error-free experiences to users.
