• Tanner Linsley's background as an open source software developer and entrepreneur • His transition from being an Angular fanboy to adopting React around 2014-2015 • How his experience using open source libraries, particularly Angular, led him to create his own open source projects • The creation of Nozzle, a startup that uses reverse-engineered Google search rankings • The development of the TanStack, a set of projects including react-query, react-table, and react-charts • The branding and marketing of the TanStack as a cohesive entity • Creation of the TanStack umbrella for hosting personal projects • Background on building popular libraries including React Query, React Table, and others • Managing open-source libraries as a co-founder of Nozzle and founder of individual projects • Balancing startup responsibilities with maintaining open-source libraries • Importance of contributors and maintainers in helping manage library growth • The role of react-query as a data synchronization library, not just a fetching library • React Query synchronization with remote data • Cache as a temporary mirror of remote data • Misconceptions about React Query being a GraphQL library or replacement for Axios • React Query's flexibility in handling asynchronous data sources (e.g. promises, Firebase subscriptions) • Use of custom hooks to encapsulate query logic and side effects • Automatic caching and invalidation with customizable configuration options • Aggressive but sane defaults for fetching data, prioritizing up-to-date data over network bandwidth concerns • Discussion of aggressive vs. gentle cache invalidation strategies • Configuring react-query hooks for specific caching behavior • Semi-persistent caching features and automatic garbage collection • Hiding asynchronous data complexities with react-query • Placeholder and initial data concepts for hydrating cached data • Server-side rendering (SSR) hydration and suspense support • React-query dev tools and inspiration from other libraries • Development of React dev tools with in-line styles • Transition to using TypeScript for the project and its libraries • Challenges and trade-offs of using generics and writing library TypeScript code • Discussion on the current state and improvements of TypeScript features • Introduction to react-table as a headless UI utility • Downshift utility for building autocomplete and select box experiences • React-table library evolution from component-based to headless, render-prop based design • Benefits of headless design, including customizability and flexibility • Challenges with traditional component libraries, such as styling and markup inflexibility • Features and utilities provided by react-table, including data manipulation and modeling • Comparison with other libraries and components, such as AG Grid and Material-UI table • Discussion around react-query and react-table integration • Version 8 improvements in react-table, including TypeScript support, API surface area, and performance enhancements • Controlled tables feature allowing developers to manage table state externally • Plugin system changes, with version 8 incorporating previously separate plugins into a monolithic bundle • Developer experience improvements, including better type safety and autocompletion • Open source sustainability model discussion, including sponsorship for libraries • React-table version 8 will be released in alpha and beta stages for upper and lower-level sponsors before a general public release. • Sponsorship tiers will be available through GitHub Sponsors to support the development of react-table. • The goal is to explore sustainability in open source software, prevent burnout, and ensure packages remain maintained. • A paid manifestation of an open-source entity is being considered, similar to AG Grid or Remix.
