5## Use Single Dependency Versions Across Monorepo
6 
7Use a single version of each dependency across all packages in your monorepo.
8Prefer exact versions over ranges. Multiple versions cause duplicate code in
9bundles, runtime conflicts, and inconsistent behavior across packages.
10 
11Use a tool like syncpack to enforce this. As a last resort, use yarn resolutions
12or npm overrides.
13 
14**Incorrect (version ranges, multiple versions):**
15 
16```json
17// packages/app/package.json
18{
19  "dependencies": {
20    "react-native-reanimated": "^3.0.0"
21  }
22}
23 
24// packages/ui/package.json
25{
26  "dependencies": {
27    "react-native-reanimated": "^3.5.0"
28  }
29}
30```
31 
32**Correct (exact versions, single source of truth):**
33 
34```json
35// package.json (root)
36{
37  "pnpm": {
38    "overrides": {
39      "react-native-reanimated": "3.16.1"
40    }
41  }
42}
43 
44// packages/app/package.json
45{
46  "dependencies": {
47    "react-native-reanimated": "3.16.1"
48  }
49}
50 
51// packages/ui/package.json
52{
53  "dependencies": {
54    "react-native-reanimated": "3.16.1"
55  }
56}
57```

59Use your package manager's override/resolution feature to enforce versions at
60the root. When adding dependencies, specify exact versions without `^` or `~`.
