How to share @mf-types between Host and Remote when using only runtime dependency (v2.0)

[Kim-soung-won]

I have been developing a Module Federation environment using Rsbuild and the associated build-time plugins for type sharing. My current setup successfully shares types between the Host and Remotes during the build process.

I am now transitioning my Host application to be runtime-based (using dynamic remote resolution). I have already upgraded to Module Federation 2.0, and the runtime logic for loading remotes works perfectly.

The Problem

While the application logic functions as expected at runtime, I am struggling with type synchronization. In a build-less or dynamic runtime host scenario, the Host doesn't necessarily have a static reference to the Remote at build time to pull @mf-types.

Questions

1. Is it possible for a Host to resolve or fetch @mf-types from a Remote using only runtime dependencies/configurations?
2. If the Host resolves remotes dynamically via the init or registerRemotes API, what is the recommended workflow to ensure the developer environment still has access to the Remote's types?
3. Are there plans or existing utilities within the @module-federation/enhanced or @module-federation/typescript ecosystem to "hot-fetch" types for a runtime-driven Host?

Environment

• Framework: Rsbuild
• MF Version: 2.0
• Language: TypeScript

I would appreciate any insights or recommended patterns for managing types when the relationship between Host and Remote is defined at runtime rather than build time.
