Dependency Filters
bun outdated supports searching for outdated dependencies by package names and glob patterns.
To check if specific dependencies are outdated, pass the package names as positional arguments:
$bun outdated eslint-plugin-security eslint-plugin-sonarjs
bun outdated v1.2.23
Package
Current

eslint-plugin-security (dev)
2.1.1
2.1.1
3.0.1
eslint-plugin-sonarjs (dev)
0.23.0
0.23.0
3.0.1
You can also pass glob patterns to check for outdated packages:
$bun outdated 'eslint*'
bun outdated v1.2.23
