🎓 How to use

// in your gatsby-config.js
plugins: [
  {
    resolve: 'gatsby-transformer-remark',
    options: {
      plugins: [
        {
          resolve: 'gatsby-remark-toc',
          options: {
            header: {
              text: 'Table of Contents', // the custom header text
              depth: 2 // the custom depth of header
            },
            /**
             * or, alternatively, you can only specify header text
             * this way, depth will be set to 2 by default
             */
            // header: 'Table of Contents',
            include: [
              'content/**/*.md' // an include glob to match against
            ]
          }
        }
      ]
    }
  }
];

If you want your table of contents to appear at a specific place in your Markdown file, use the reuseExistingHeader option:

// in your gatsby-config.js
plugins: [
  {
    resolve: 'gatsby-transformer-remark',
    options: {
      plugins: [
        {
          resolve: 'gatsby-remark-toc',
          options: {
            header: 'Table of Contents', // the custom header text
            reuseExistingHeader: true, // searches for `Table of Contents` in your Markdown file and adds the list right after it
            include: [
              'content/**/*.md' // an include glob to match against
            ]
          }
        }
      ]
    }
  }
];

Use the orderedList option if you want to change the list type from <ul> to <ol>.

Meanwhile, you can specify a wrapper container for table of contents:

// in your gatsby-config.js
plugins: [
  {
    resolve: 'gatsby-transformer-remark',
    options: {
      plugins: [
        {
          resolve: 'gatsby-remark-toc',
          options: {
            header: 'Table of Contents', // the custom header text
            wrapper: {
              name: 'aside', // tagName of wrapper component
              properties: {
                // attributes of wrapper component
                class: 'custom-class-here'
                // you can add more here, such as aria-hidden: true, etc.
              }
            },
            // or, alternatively you can simply pass a string here, which will be used as tagName
            // wrapper: 'aside',
            include: [
              'content/**/*.md' // an include glob to match against
            ]
          }
        }
      ]
    }
  }
];

Additionally, you can pass custom options directly to mdast-util-toc like so:

// in your gatsby-config.js
plugins: [
  {
    resolve: 'gatsby-transformer-remark',
    options: {
      plugins: [
        {
          resolve: 'gatsby-remark-toc',
          options: {
            header: 'Table of Contents', // the custom header text
            include: [
              'content/**/*.md' // an include glob to match against
            ],
            mdastUtilTocOptions: {
              maxDepth: 2
            }
          }
        }
      ]
    }
  }
];
