    Designing an Ideal Linting Developer Experience with Flint | Josh Goldberg | Ep 62B

    In this episode with Josh Goldberg, maintainer of TypeScript ESLint, we dive into his latest research project, Flint. The goal of Flint is to test different hypothesis on how to architect a modern, hybrid-native JavaScript and TypeScript linter. What happens when every rule can be type-aware? Can you write lint rules in TypeScript and run them with near-native performance? How can error messages be more helpful for humans and agents alike? How can the configuration and plugin system be re-designed so it's less magical and has more type safety? These are the kinds of questions the Flint team is exploring and we talk with Josh about how things are progressing and where Flint's future is headed.
