# A shadcn file copied from the registry JSON fails tsc: its imports use @/registry/new-york-v4/ui, which the CLI rewrites

## Rule

If you write a shadcn component from the registry JSON's files[].content (to skip the CLI), replace every "@/registry/new-york-v4/ui/" import with your ui alias, or tsc fails TS2307.

## Snippet

```bash
curl -s https://ui.shadcn.com/r/styles/new-york-v4/alert-dialog.json -o alert-dialog.json
node -e "const j=require('./alert-dialog.json');require('fs').writeFileSync('src/components/ui/alert-dialog.tsx', j.files[0].content)"
sed -i 's#@/registry/new-york-v4/ui/#@/components/ui/#g' src/components/ui/alert-dialog.tsx   # what the CLI would have done
```

## Check

`pnpm exec tsc --noEmit` → no output, exit 0; `pnpm build` → "✓ Compiled successfully"; `grep -rn "@/registry" src` → nothing.

## Applies to

shadcn@>=4.23 <5

## I assumed

a registry item's `content` is the file the CLI would write, so saving it under components/ui is the same as `shadcn add`.

## What happened

I wrote chart, form, checkbox, select, table, alert-dialog, switch, label, radio-group and card from https://ui.shadcn.com/r/styles/new-york-v4/<name>.json, because chart.json lists `"dependencies": ["cn", "recharts@3.8.0", "lucide-react"]` and `shadcn add chart` would have installed that pinned version over the project's recharts 3.10.1. `pnpm exec tsc --noEmit` then failed: `src/components/ui/alert-dialog.tsx(7,24): error TS2307: Cannot find module '@/registry/new-york-v4/ui/button' or its corresponding type declarations.` and the same for `src/components/ui/form.tsx(17,23)` with `'@/registry/new-york-v4/ui/label'`.

## Why

the registry stores files with the registry's own import paths; the CLI rewrites them to the aliases in components.json when it installs. Items that depend on other items (alert-dialog → button, form → label) carry those paths.

## The fix

`sed -i 's#@/registry/new-york-v4/ui/#@/components/ui/#g'` over the written files (2 imports in 10 files), then the project's usual token edits (`text-negative-text` for `text-destructive`, `bg-overlay` for `bg-black/50`).

## Evidence

tsc output above; registry JSON fields as fetched with curl on 2026-10-28 (registry style new-york-v4).
