Sam and Ryan discuss how TypeScript helped them understand the mechanics of how props get passed from Server Components to Client Components, and how to properly type client component props if the prop starts out as a rich data type on the server. They also clarify some points from last episode’s discussion about the RSC payload.

Topics include:

• 0:00 - Intro
• 0:40 - Clarifying what the RSC Payload actually is
• 10:12 - Understanding prop serialization when passing props from Server Components to Client Components
• 23:38 - How to define TypeScript types for serialized props, and Remix’s SerializeFrom helper
