TypeScript for Product Teams

About this course

TypeScript is most valuable when it reflects the product domain, not only the framework of the week. This course shows how product-minded engineers use types to document intent, catch integration mistakes early, and keep refactors safe. We cover modeling domain states, narrowing unsafe data at boundaries, designing shared DTOs, and collaborating with designers and PMs using typed vocabulary. The curriculum stays practical: every lesson ends with a checklist you can apply to an existing codebase. Expect a focus on clarity over cleverness. The goal is readable types that help the next engineer, not a showcase of advanced language features.

Who it is for

• Product engineers working in TypeScript codebases
• Frontend and backend pairs sharing contracts
• Teams migrating from loose JavaScript models
