Docusaurus Plugins

Docusaurus Plugin Guide

Quick Start

// Remark plugin - transforms markdown AST
module.exports = function remarkPlugin(options = {}) {
  return async function transformer(ast, vfile) {
    const { visit } = require("unist-util-visit");

    visit(ast, "link", (node) => {
      // Transform nodes
      node.data = node.data || {};
      node.data.hProperties = { className: "custom" };
    });

    return ast;
  };
};

// In docusaurus.config.js:
// remarkPlugins: [require('./plugins/my-plugin')]

Core Principles

• 5 Plugin Types: Remark (markdown), Rehype (HTML), Lifecycle (routes/webpack), Theme (components), Content (custom data)
• Remark: Transforms markdown before HTML conversion, use unist-util-visit for AST traversal
• Rehype: Transforms HTML after compilation, processes HAST (HTML AST)
• Lifecycle: Most flexible, implements hooks like loadContent(), contentLoaded(), postBuild()
• Export function: Returns transformer (remark/rehype) or plugin object (lifecycle)
