shadcn Migration
Agent Workflow (MANDATORY)
Before migration, use TeamCreate to spawn agents:
- fuse-ai-pilot:explore-codebase - Inventory all affected components
- fuse-ai-pilot:research-expert - Verify migration patterns via Context7
After: Run fuse-ai-pilot:sniper for validation.
Overview
| Feature | Description |
|---|
| Radix -> Base UI | Migrate from legacy to new primitives |
| Base UI -> Radix | Migrate to established primitives |
| API mapping | Complete transformation table |
| Validation | Post-migration checklist |
Critical Rules
- ALWAYS run detection before starting migration
- ALWAYS create backup branch before migration
- MIGRATE one component type at a time
- UPDATE CSS selectors along with JSX changes
- RUN tests after each component migration
Architecture
Migration order (leaf components first):
1. Tooltip, Switch, Checkbox (simple)
2. Accordion, Tabs (medium)
3. Dialog, Select, Popover, Menu (complex)
-> See migration-dialog.md for complete example
Pre-Migration Checklist
[ ] Run shadcn-detection to confirm current primitive
[ ] Create backup branch (git checkout -b pre-migration)
[ ] Inventory all affected files (Grep for imports)
[ ] Review component-specific API changes
[ ] Plan migration order (leaf components first)
Migration Workflow
1. DETECT -> Run shadcn-detection skill
2. BACKUP -> Create git branch
3. INVENTORY -> List all affected components
4. TRANSFORM -> Apply API changes per component
5. VALIDATE -> Run tests + sniper check
Key API Changes
| Aspect | Radix | Base UI |
|---|
| Composition | asChild | render prop |
| Dialog content | DialogContent | Dialog.Popup |
| Dialog overlay | DialogOverlay | Dialog.Backdrop |
| Positioning | Built-in | Separate Positioner |
| Accordion body | AccordionContent | Accordion.Panel |
| Data attrs | data-state="open" | data-[open] |
| Package | Multiple @radix-ui/* | Single @base-ui/react |
Best Practices
DO
- Migrate one component type at a time
- Run tests after each component migration
- Update CSS selectors along with JSX
- Remove unused Radix packages after migration
DON'T
- Migrate all components at once
- Skip detection step
- Leave mixed APIs in production
- Forget to update data-attribute CSS selectors
