5## Install Native Dependencies in App Directory
6 
7In a monorepo, packages with native code must be installed in the native app's
8directory directly. Autolinking only scans the app's `node_modules`—it won't
9find native dependencies installed in other packages.
10 
11**Incorrect (native dep in shared package only):**
12 
13```
14packages/
15  ui/
16    package.json  # has react-native-reanimated
17  app/
18    package.json  # missing react-native-reanimated
19```
20 
21Autolinking fails—native code not linked.
22 
23**Correct (native dep in app directory):**
24 
25```
26packages/
27  ui/
28    package.json  # has react-native-reanimated
29  app/
30    package.json  # also has react-native-reanimated
31```
32 
33```json
34// packages/app/package.json
35{
36  "dependencies": {
37    "react-native-reanimated": "3.16.1"
38  }
39}
40```
41 
42Even if the shared package uses the native dependency, the app must also list it
43for autolinking to detect and link the native code.
