How-to guides

How-to guides assume you know the basics and want to get a specific job done.

• Migrate v1 → v2 — update an existing Reactra app to the v2 DSL.
• Control re-render granularity — make a component re-render only when it must.
• Render outside the tree with Portal — escape overflow, transform, and z-index ancestors for toasts and modals.
• Fetch and cache data
• Persist state across routes
• Add DI for testing
• Record and replay a session
• Debug a compile error
