Community Plugin

gatsby-source-multigitmarkdown

The plugin is a source plugin that helps in pulling content of MD files from different github repositories. It can also be configured to get content from same repository but different md files. Each md file content and it’s configured metadata is created as a node in an array of nodes.

Dependencies

The project used the following libraries

axios (for making the http call to fetch content)
remark (for parsing the contents of md files into a HTML)

How to install

To install the plugin you may run the following command

For NPM:

   npm -i gatsby-source-multigitmarkdown

For Yarn:

    yarn add gatsby-source-multigitmarkdown

To use the plugin, add the following into the gatsby-config.js

module.exports = {
  siteMetadata: siteMetadata,
  plugins: [
    {
      resolve: `gatsby-multigitsource-plugin`,
      options: {
        pages: [{
          repo: "arunmadhavan-g/config-driven-ui",
          file: "README.md",
          title: "Building a Config Driven UI in React - Part 1",

        }]
      }
    }]
}

Available options

Options	Description
pages.repo	the username and repository name part of the repo URL
pages.file	The name of the md file
pages.title	The Page title
pages.publishedOn	The published date of the page
page.author	author’s name
page.tags	tags associated with the page
page.description	A short Description of what the page does

The above mentioned options would be exposed as part of the graphql node. Information passed in pages.repo and pages.file will be utlilised for fetching the md file content.

When do I use this plugin?

The motivation behind building this plugin was to aggregate content from multiple github repositries into a single blog platform This helps in adding pages with sources coming from different public repositories md file into a single place.

Examples of usage

Add the following code with proper options to your gatsby-config.js

module.exports = {
  siteMetadata: siteMetadata,
  plugins: [
    {
      resolve: `gatsby-multigitsource-plugin`,
      options: {
        pages: [{
          repo: "arunmadhavan-g/config-driven-ui",
          file: "README.md",
          title: "Building a Config Driven UI in React - Part 1",
          publishedOn: "2019-11-24T12:39:18.088Z",
          author: "Arun Madhavan",
          tags: ["reactjs", "javascript", "ui"],
          description: "Part 1 of a 2 part blog, where I share my experiences with development of a configuration driven UI to build their executive dashboard",
        }]
      }
    }]
}

The data can be queried using the following graphQL query

query MyQuery {
  allMultiGitSource {
    edges {
      node {
        pageInfo {
          author
          content
          description
          pagePath
          publishedOn
          tags
          title
        }
      }
    }
  }
}

For example we can query the data in gatsby-node.js and createPages for each of the returned information as shown below

exports.createPages = async ({ graphql, actions: { createPage } }) =>
  (await graphql(`
  query MyQuery {
    allMultiGitSource {
      edges {
        node {
          pageInfo {
            author
            content
            description
            pagePath
            publishedOn
            tags
            title
          }
        }
      }
    }
  }`)).data.allMultiGitSource.edges.map(x => x.node.pageInfo).forEach(page => {
    createPage({
      path: `/${_.camelCase(page.title)}`,
      component: require.resolve("./src/templates/page-template.js"),
      context: { page },
    })
  })

How to query for data

The data is made available as part of allMultiGitSource node. Contents can be queried using a query like below.

query MyQuery {
  allMultiGitSource {
    edges {
      node {
        pageInfo {
          author
          content
          description
          pagePath
          publishedOn
          tags
          title
        }
      }
    }
  }
}
