gatsby-source-license

Continuous integration Vulnerabilities codecov npm version

Gatsby source plugin for pulling software license information from dependencies.

The plugin reads the dependencies from package.json, and will check the node_modules directories for these dependencies and their licenses. In addition, it also checks nested dependencies, and should work for npm 3.x and higher.

Install

This plugin can be installed by using:

npm install --save gatsby-source-license

How to use

// In your gatsby-config.js
module.exports = {
  plugins: [
    {
      resolve: `gatsby-source-license`,
      options: {
        // The amount of nested dependencies that should be checked.
        // 1 = Only the license within the current package.json is sourced
        // 2 = Licenses of direct dependencies and the current package are sourced
        // Infinity = All dependencies will be checked.
        // Default = Infinity
        depth: Infinity,
        // Indicates whether the own software license should be sourced or not.
        // Be aware that this may conflict with maxDepth.
        // If you set this to true, and have a maxDepth of 1, no software license will be sourced.
        // Default = true
        excludeSelf: true,
        // A list of excluded dependencies, using the format library@1.0.0.
        // For example, if we want to exclude ESLint version 6.8.0, we use [`eslint@6.8.0`]
        // Default = []
        excludedDependencies: [],
        // Indicates whether normal dependencies should be sourced or not.
        // If you set this to true, normal dependencies will be sourced.
        // Default = true
        includeDependencies: true,
        // Indicates whether development dependencies should be sourced or not.
        // If you set this this to true, development dependencies (dependencies installed with --save-dev) will be sourced.
        // Default = false
        includeDevDependencies: false
      }
    }
  ]
};

How to query

Once done, you can query for the software licenses your project uses, by using the following query:

query {
  allSoftwareLicenseLibrary {
    edges {
      node {
        license
        label
        url
        name
        version
      }
    }
  }
}

This would return a JSON structure similar to:

{
  "allSoftwareLicenseLibrary": {
    "edges": [
      {
        "node": {
          "license": "MIT",
          "label": "gatsby-source-license@0.0.1",
          "url": "https://github.com/g00glen00b/gatsby-source-license",
          "name": "gatsby-source-license",
          "version": "0.0.1"
        }
      }
    ]
  }
}
