## Summary
[dependency-cruiser](https://github.com/sverweij/dependency-cruiser/tree/main)
is used for building dependency graph.
### Show all dependencies for a specific package/plugin or directory
#### Run for all plugins
```bash
bash scripts/dependency_usage.sh -p x-pack/plugins -o ./tmp/deps-result-all.json
```
#### Run for single plugin
```bash
bash scripts/dependency_usage.sh -p x-pack/plugins/security_solution -o ./tmp/deps-result-single.json
```
#### Run for multiple plugins
```bash
bash scripts/dependency_usage.sh -p x-pack/plugins/security_solution x-pack/plugins/security -o ./tmp/deps-result-multiple.json
```
#### Run for `x-pack/packages`
```bash
bash scripts/dependency_usage.sh -p x-pack/packages -o ./tmp/deps-packages-1.json
```
#### Run for `packages`
```bash
bash scripts/dependency_usage.sh -p packages -o ./tmp/deps-packages-2.json
```
#### Benchmark
| Analysis | Real Time | User Time | Sys Time |
|-----------------------|-------------|-------------|------------|
| All plugins | 7m 21.126s | 7m 53.099s | 20.581s |
| Single plugin | 31.360s | 45.352s | 2.208s |
| Multiple plugins | 36.403s | 50.563s | 2.814s |
| x-pack/packages | 6.638s | 12.646s | 0.654s |
| packages | 25.744s | 39.073s | 2.191s |
#### Show all packages/plugins within a directory that use a specific
dependency
```sh
bash scripts/dependency_usage.sh -d rxjs -p x-pack/plugins/security_solution
```
---
#### Show all packages/plugins within a directory grouped by code owner
```sh
bash scripts/dependency_usage.sh -d rxjs -p x-pack/plugins -g owner
```
---
#### Group by code owner with adjustable collapse depth for fine-grained
grouping
**Fine-grained grouping**:
```sh
bash scripts/dependency_usage.sh -p x-pack/plugins/security_solution -g owner --collapse-depth 4
```
**Collapsed grouping**: groups the results under a higher-level owner
(e.g., `security_solution` as a single group).
```bash
bash scripts/dependency_usage.sh -p x-pack/plugins/security_solution -g owner --collapse-depth 1
```
---
#### Show all dependencies matching a pattern (e.g., `react-*`) within a
package
```bash
bash scripts/dependency_usage.sh -p x-pack/plugins/security_solution -d 'react-*' -o ./tmp/result.json
```
