API

This package exports the following:

remarkGfmCustom

function remarkGfmCustom(options?: Options): void;

The main plugin. It receives one optional parameter to configure behavior. See the Options section below for configuration details.

Options

  remarkGfm?: FootnoteOptions | TableOptions | StrikethroughOptions;
  plugins?: {
    autolinkLiteral?: boolean;
    footnote?: boolean;
    strikethrough?: boolean;
    table?: boolean;
    taskListItem?: boolean;
  };
};

Configuration for remarkGfmCustom. This consists of two main categories: remarkGfm and plugins.
