He shares his journey into open source and the importance of filling in the gaps in the ecosystem. He also discusses the best incremental migration path to TypeScript and highlights advanced features like shenanigans with type parameters and the 'satisfies' keyword. The conversation covers topics such as literals in TypeScript, writing a book, the process of writing and shipping a book, the reception of the book, the development of TypeScript ESLint, abstract syntax trees (ASTs), parsing, and static analysis. We also discuss the future of TypeScript, the performance of ESLint, and configuration tips to improve ESLint's performance. Takeaways1. Being a full-time independent open source maintainer is rewarding and allows for direct contributions to tools that benefit everyone.2. When migrating to TypeScript, it's best to start with one file at a time and gradually increase strictness.3. Type parameters in TypeScript can be complex, but they are useful for advanced scenarios.4. The 'satisfies' keyword in TypeScript allows for declaring data that adheres to a type while still inferring a more specific type.5. Parsing is the process of converting a string of code into an AST.6. ESLint provides a report function that allows lint rules to report issues to the user.7. TypeScript ESLint supports typed linting, which allows for more powerful linting rules.8. ESLint's performance can be affected by misconfiguration, the number of plugins, and the use of ESLint plugin prettier.9. Separating ESLint and Prettier as separate tools can improve performance.10. Being an open-source maintainer can be challenging, but having a fallback plan and a supportive community can make it sustainable.Chapters00:00 Josh Goldberg03:37 Introduction and Background06:22 The Journey into Open Source and Filling in the Gaps15:15 The Best Incremental Migration Path to TypeScript28:41 Introducing the 'Satisfies' Keyword in TypeScript30:31 The Process of Writing and Shipping a Book35:10 The Development of TypeScript ESLint37:26 Parsing and Static Analysis with Abstract Syntax Trees56:54 Improving ESLint Performance: Configuration Tips01:01:00 Understanding the Role of ASTs and Compilers in TypeScript and ESLint01:03:42 Configuring Type Linting in TypeScript01:06:22 The Intersection of AI with TypeScript and ESLint01:11:53 Creating a Standardized Open-Source Sponsorship Rating System

Cross, co-founder of NX, discusses the origins of NX and its evolution as a tool for monorepos. He explains the benefits of using NX, such as code mod running, large-scale migrations, and CI optimizations. Jeff also clarifies the definition of a monorepo and how NX supports both package-based and graph-based monorepos. He highlights the features of NX that help with development, integration, and deployment, including the interactive graph, tagging system, and caching. We also cover the ability of NX to deflake tests and shares his perspective on running a business, including the challenges of positioning and marketing, and his experience of starting NX. Takeaways1. NX is a powerful tool for monorepos that offers features such as code mod running, large-scale migrations, and CI optimizations.2. A monorepo can be defined as a single repository containing multiple distinct projects with well-defined relationships.3. NX supports both package-based and graph-based monorepos, with the latter being more suitable for application developers.4. NX also offers features for integration and deployment, such as building affected targets, replaying builds and tests, and distributing work across multiple machines.5. NX has the ability to deflake tests, which are tests that indeterministically fail or pass. NX detects and handles flaky tests by analyzing test results and determining if a test fails often or fails without changes in inputs or dependencies.6. Measuring the developer experience is challenging, but NX uses user feedback, internal testing, and collaboration with enterprise customers to improve the product.7. Positioning and marketing a product can be a difficult task, especially for a tool like NX that doesn't fit into a specific category.8. Finding a niche and being the best in the world at it is crucial for success as a consultant or business owner.9. Continuous adaptation and evolution are essential qualities for a CEO, as they need to be able to change and pivot as the company grows.10. Polygraph, an upcoming feature of Nx, will provide visibility and dependency management across multiple workspaces in an organization.Chapters00:00:00 Jeff Cross00:03:18 Introduction and Origins of NX00:06:25 Understanding Monorepos and NX00:11:04 Tools for Development and Code Consistency00:14:56 Integration and Deployment with NX00:36:09 Detecting and Handling Flaky Tests00:38:20 The Developer Experience with NX00:48:36 Understanding Lexers, Parsers, Compilers, and Rich Text Editors01:00:54 Challenges of Positioning and Marketing01:03:36 Starting and Running a Business01:10:47 The impact of Nx Cloud on CI performance01:18:49 Introducing Polygraph: Visibility and dependency management01:27:46 What's next for Nx01:31:47 Conclusion

Wiz is a resumable web framework that focuses on loading minimal JavaScript and uses the concept of signals for reactive programming. Signals are reactive properties that reflect the state of an observable or reactive property at any given time. The Wiz framework also incorporates JS Action, a library that listens to events and delivers them to event handlers only when necessary, reducing the amount of JavaScript that needs to be loaded. The conversation also touches on the merger of Wiz and Angular and the potential for unified APIs in the future. The conversation explores the concept of responsible JavaScript and web performance. We dive into the use of signals and JS action in Wiz and Angular, and how they enable declarative behavior and interactivity on the client side. The discussion also touches on the challenges of using TSX in Angular and the potential for future improvements. The importance of measuring performance and understanding the user experience on different devices is emphasized, along with the use of feature flags and instrumentation to optimize the user funnel.Takeaways1.
