Restrictions

This plugin does not operate on the GraphQL Layer. Any content source that plugs in via GraphQL should not work with it. It only works with source plugins that operate on the Gridsome Data Store API. Tested with gridsome-source-filesystem

Install

• yarn add gridsome-plugin-recommender
• npm install gridsome-plugin-recommender --save

Getting Started

Example: Find similar blog posts based on the title. You can find a more complex example on GitHub under /example

module.exports = {
  plugins: [
    {
      use: '@gridsome/source-filesystem',
      options: {
        path: 'content/posts/**/*.md',
        typeName: 'Post',
      },
    },
    {
      use: "gridsome-plugin-recommender",
      options: {
        enabled: true,
        typeName: 'Post',
        referenceTypeName: 'Tag',
        field: 'title',
        referenceField: 'title',
        relatedFieldName: 'related',
        referenceRelatedFieldName: 'related',
        caseSensitive: false,
        minScore: 0.01,
        maxScore: 1,
        minRelations:3,
        maxRelations: 10,
        fillWithRandom:false,
        debug: false
      }
    }
  ]
};

Important notice: the plugin needs to be placed below your source plugins or otherwise no required collections are created before. Issue-1342

In your templates use something like this

<page-query>
    query RelatedPosts {
      allPost(filter:{id:{eq:"current-post-id"}}) {
        edges {
          node {
            id
            related{
              id
              path
            }
          }
        }
      }
    }
</page-query>

The reference collection we want to use to create relations of default collection nodes.

field

• Type: [string] required

referenceField

• Type: [string] required

The reference collection field we want to analyze for similarities

relatedFieldName

• Type: [string]

maxScore

• Type: number [0,1]
