+name: pnpm-overrides
+description: Force specific versions of dependencies including transitive dependencies
+---
+
+# pnpm Overrides
+
+Overrides let you force specific versions of packages, including transitive dependencies. Useful for fixing security vulnerabilities or compatibility issues.
+
+## Basic Syntax
+
+Define overrides in `pnpm-workspace.yaml` (recommended) or `package.json`:
+
+### In pnpm-workspace.yaml (Recommended)
+
+```yaml
+packages:
+  - 'packages/*'
+
+overrides:
+  # Override all versions of a package
+  lodash: ^4.17.21
+  
+  # Override specific version range
+  "foo@^1.0.0": ^1.2.3
+  
+  # Override nested dependency
+  "express>cookie": ^0.6.0
+  
+  # Override to different package
+  "underscore": "npm:lodash@^4.17.21"
+```
+
+### In package.json
+
+```json
+{
+  "pnpm": {
+    "overrides": {
+      "lodash": "^4.17.21",
+      "foo@^1.0.0": "^1.2.3",
+      "bar@^2.0.0>qux": "^1.0.0"
+    }
+  }
+}
+```
+
+## Override Patterns
+
+### Override all instances
+```yaml
+overrides:
+  lodash: ^4.17.21
+```
+Forces all lodash installations to use ^4.17.21.
+
+### Override specific parent version
+```yaml
+overrides:
+  "foo@^1.0.0": ^1.2.3
+```
+Only override foo when the requested version matches ^1.0.0.
+
+### Override nested dependency
+```yaml
+overrides:
+  "express>cookie": ^0.6.0
+  "foo@1.x>bar@^2.0.0>qux": ^1.0.0
+```
+Override cookie only when it's a dependency of express.
+
+### Replace with different package
+```yaml
+overrides:
+  # Replace underscore with lodash
+  "underscore": "npm:lodash@^4.17.21"
+  
+  # Use local file
+  "some-pkg": "file:./local-pkg"
+  
+  # Use git
+  "some-pkg": "github:user/repo#commit"
+```
+
+### Remove a dependency
+```yaml
+overrides:
+  "unwanted-pkg": "-"
+```
+The `-` removes the package entirely.
+
+## Common Use Cases
+
+### Security Fix
+
+Force patched version of vulnerable package:
+
+```yaml
+overrides:
+  # Fix CVE in transitive dependency
+  "minimist": "^1.2.6"
+  "json5": "^2.2.3"
+```
+
+### Deduplicate Dependencies
+
+Force single version when multiple are installed:
+
+```yaml
+overrides:
+  "react": "^18.2.0"
+  "react-dom": "^18.2.0"
+```
+
+### Fix Peer Dependency Issues
+
+```yaml
+overrides:
+  "@types/react": "^18.2.0"
+```
+
+### Replace Deprecated Package
+
+```yaml
+overrides:
+  "request": "npm:@cypress/request@^3.0.0"
+```
+
+## Hooks Alternative
+
+For more complex scenarios, use `.pnpmfile.cjs`:
+
+```js
+// .pnpmfile.cjs
+function readPackage(pkg, context) {
+  // Override dependency version
+  if (pkg.dependencies?.lodash) {
+    pkg.dependencies.lodash = '^4.17.21'
+  }
+  
+  // Add missing peer dependency
+  if (pkg.name === 'some-package') {
+    pkg.peerDependencies = {
+      ...pkg.peerDependencies,
+      react: '*'
+    }
+  }
+  
+  return pkg
+}
+
+module.exports = {
+  hooks: {
+    readPackage
+  }
+}
+```
+
+## Overrides vs Catalogs
+
+| Feature | Overrides | Catalogs |
+|---------|-----------|----------|
+| Affects | All dependencies (including transitive) | Direct dependencies only |
+| Usage | Automatic | Explicit `catalog:` reference |
+| Purpose | Force versions, fix issues | Version management |
+| Granularity | Can target specific parents | Package-wide only |
+
+## Debugging
+
+Check which version is resolved:
+
+```bash
+# See resolved versions
+pnpm why lodash
+
+# List all versions
+pnpm list lodash --depth=Infinity
+```
