Community Plugin

gatsby-transformer-gitinfo

Add some git information on File fields from latest commit: date, author and email.

Install

npm install --save @skylerwlewis/gatsby-transformer-gitinfo

Note: You also need to have gatsby-source-filesystem installed and configured so it points to your files.

How to use

In your gatsby-config.js

module.exports = {
  plugins: [
    {
      resolve: `gatsby-source-filesystem`,
      options: {
        path: `./src/data/`,
      },
    },
    `@skylerwlewis/gatsby-transformer-gitinfo`,
  ],
}

Where the source folder ./src/data/ is a git versioned directory.

The plugin will add several fields to File nodes: gitLogLatestAuthorName, gitLogLatestAuthorEmail and gitLogLatestDate. These fields are related to the latest commit touching that file.

If the file is not versioned, these fields will be null.

They are exposed in your graphql schema which you can query:

query {
  allFile {
    edges {
      node {
        fields {
          gitLogLatestAuthorName
          gitLogLatestAuthorEmail
          gitLogLatestDate
        }
        internal {
          type
          mediaType
          description
          owner
        }
      }
    }
  }
}

Now you have a File node to work with:

{
  "data": {
    "allFile": {
      "edges": [
        {
          "node": {
            "fields": {
              "gitLogLatestAuthorName":"John Doe",
              "gitLogLatestAuthorEmail": "john.doe@github.com",
              "gitLogLatestDate": "2019-10-14T12:58:39.000Z"
            },
            "internal": {
              "contentDigest": "c1644b03f380bc5508456ce91faf0c08",
              "type": "File",
              "mediaType": "text/yaml",
              "description": "File \"src/data/example.yml\"",
              "owner": "gatsby-source-filesystem"
            }
          }
        }
      ]
    }
  }
}

Configuration options

include [regex][optional]

This plugin will try to match the absolute path of the file with the include regex. If it does not match, the file will be skipped.

module.exports = {
  plugins: [
    {
      resolve: `@skylerwlewis/gatsby-transformer-gitinfo`,
      options: {
        include: /\.md$/i, // Only .md files
      },
    },
  ],
}

ignore [regex][optional]

This plugin will try to match the absolute path of the file with the ignore regex. If it does match, the file will be skipped.

module.exports = {
  plugins: [
    {
      resolve: `@skylerwlewis/gatsby-transformer-gitinfo`,
      options: {
        ignore: /\.jpeg$/i, // All files except .jpeg
      },
    },
  ],
}

dir [string][optional]

The root of the git repository. Will use current directory if not provided.
