This was a talk given at the 11ty International Symposium on Making Web Sites Real Good (2024): https://conf.11ty.dev/2024/11ty-and-large-project-tooling/

JetBrains has a knowledge base with lots of content, customizing, authors, developers… so we built it in Gatsby. Then switched to 11ty. But we wanted to keep some of the large-project tooling, so we added it. In this talk, we'll cover component driven development through TypeScript and TSX, unit testing with Vitest, in-editor validation of Markdown frontmatter for authors, content queries, and more.
