The gatsby-plugin-excerpts from yoshiwalsh

Truncating an excerpt leaves html, head and body tags

Using a modified example from #2 with no replacements and adding truncation:

{
  resolve: `gatsby-plugin-excerpts`,
  options: {
    sources: {
      beheadedDescription: {
        type: 'htmlQuery',
        sourceField: 'description',
        excerptSelector: 'body > *',
        elementReplacements: [],
        truncate: {
          stripTags: true,
          length: 80,
          byWords: true,
          ellipsis: '…'
        },
      },
    },
    sourceSets: {
      beheadDescription: [
        `beheadedDescription`
      ]
    },
    excerpts: {
      processedDescription: {
        type: `html`,
        nodeTypeSourceSet: {
          ContentYaml: `beheadDescription`
        }
      }
    }
  },
}

Produces a result like:

{
  "beheadDescription": "<html><head></head><body>Wherever you are Put your stuff in Dropbox and get to it from your computers, phones, or tablets. Edit docs, automatically add photos, and show off videos from anywhere.Share with confidence Share photos with friends. Work with your team like you&apos;re using a single computer. Everything&apos;s automatically private, so you control who sees what.Safe and secure Even if your phone goes for a swim, your stuff is always safe in Dropbox and can be restored in a snap. Dropbox secures&#x2026;</body></html>"
}

All tags are properly stripped because of the truncate stripTags flag, however html, head, and body are left within the results.

Error: TypeError: Cannot read property 'call' of undefined

I'm trying to use this excerpt on html that is coming from markdown within yaml.

Plugins I'm using:

gatsby-transformer-yaml-full
gatsby-yaml-full-markdown
gatsby-plugin-excerpts

Here is an example yaml file:

name: Dropbox
description: !markdown |
  **Wherever you are**  
  Put your stuff in Dropbox and get to it from your computers, phones, or tablets. Edit docs, automatically add photos, and show off videos from anywhere.

My excerpts config looks like this:

{
  resolve: `gatsby-plugin-excerpts`,
  options: {
    sources: {
      snippetBlocks: {
        type: 'htmlQuery',
        sourceField: 'description',
        stripSelector: 'a',
        elementReplacements: [
          {
            selector: 'h6',
            replaceWith: 'strong'
          },
          {
            selector: 'h5',
            replaceWith: 'h6'
          },
          {
            selector: 'h4',
            replaceWith: 'h5'
          },
          {
            selector: 'h3',
            replaceWith: 'h4'
          },
          {
            selector: 'h2',
            replaceWith: 'h3'
          },
        ],
      },
      default: {
        type: 'htmlQuery',
        sourceField: 'html',
        excerptSelector: 'html > *',
        ignoreSelector: 'img, .gatsby-highlight',
        stripSelector: 'a',
        elementReplacements: [
          {
            selector: 'h6',
            replaceWith: 'strong'
          },
          {
            selector: 'h5',
            replaceWith: 'h6'
          },
          {
            selector: 'h4',
            replaceWith: 'h5'
          },
          {
            selector: 'h3',
            replaceWith: 'h4'
          },
          {
            selector: 'h2',
            replaceWith: 'h3'
          },
        ],
        truncate: {
          length: 80,
          byWords: true,
          ellipsis: '…'
        },
      }
    },
    sourceSets: {
      markdownHtml: [
        `snippetBlocks`,
        `default`
      ]
    },
    excerpts: {
      snippet: {
        type: `html`,
        nodeTypeSourceSet: {
          ToolkitYaml: `markdownHtml`
        }
      }
    }
  },
}

When running this in the GraphQL explorer my console is outputting:
