@rnx-kit/lint-lockfile is a standalone tool for scanning your lockfiles for potential issues.

Supported lockfile formats:

Installation

yarn add @rnx-kit/lint-lockfile --dev

Usage

yarn lint-lockfile

Configuration

@rnx-kit/lint-lockfile can be configured in your root package.json file. For example:

{
  "rnx-kit": {
    "lint": {
      "lockfile": {
        "noDuplicates": {
          "enabled": true, // enabled by default
          "packages": [
            "react",
            "react-native"
          ]
        },
        "noWorkspacePackageFromNpm": {
          "enabled": true // enabled by default
        }
      }
    }
  }
}

Rules

`noDuplicates`

This rule checks for duplicate packages in the lockfile. It must be configured to check for specific packages. For example, to check for duplicates of React and React Native, configure it like this:

{
  "rnx-kit": {
    "lint": {
      "lockfile": {
        "noDuplicates": {
          "packages": [
            "react",
            "react-native"
          ]
        }
      }
    }
  }
}

You can allow multiple copies of a package by specifying a max count:

{
  "rnx-kit": {
    "lint": {
      "lockfile": {
        "noDuplicates": {
          "packages": [
            "react-native",
            ["react", 2], // allow up to 2 copies of `react`
            ["left-pad", 0] // disallow `left-pad` entirely
          ]
        }
      }
    }
  }
}

This rule also has a built-in preset for React Native. You can enable it with #react-native:

{
  "rnx-kit": {
    "lint": {
      "lockfile": {
        "noDuplicates": {
          "packages": [
            "#react-native"
          ]
        }
      }
    }
  }
}

`noWorkspacePackageFromNpm`

This rule checks for workspace packages that are unintentionally installed from npm. It is enabled by default, but can be disabled like this:

{
  "rnx-kit": {
    "lint": {
      "lockfile": {
        "noWorkspacePackageFromNpm": {
          "enabled": false
        }
      }
    }
  }
}
