Documentation.js supports customizable themes for HTML output. A theme is a Node.js module that exports a single function with the following signature:

/**
 * @function
 * @param {Array<Object>} comments - an array of comments to be output
 * @param {Object} options - theme options
 * @param {ThemeCallback} callback - see below
 */

/**
 * @callback ThemeCallback
 * @param {?Error} error
 * @param {?Array<vinyl.File>} output
 */

The theme function should call the callback with either an error, if one occurs, or an array of vinyl File objects.

The theme is free to implement HTML generation however it chooses. See the default theme for some ideas.

Customizing the Default Theme

Instructions

  • Copy contents of default_theme folder (noted above) into a new folder in your project. One way to do it is to create a new git repository with the folder contents and add this line to your package.json devDependencies section: "docjs-theme": "my-gh-username/reponame". That way when you install dependencies, your new theme will be in the projects node_modules folder.

  • In the folder you created, replace require('../') on lines 10 and 11 of index.js with require('documentation') and save.

  • You can now make changes that will show up when you generate your docs using your theme. Example package.json scripts entry: "documentation build index.js -f html -o docs --theme node_modules/docjs-theme"

Theming Markdown

The default Markdown generator for documentation.js isn't customizable - instead of a plain-text theme, it's generated by creating an AST and then rendering it with remark. If you need something extra in Markdown, you can either rally for that thing to be included in the default theme, or you can hack around it by using an HTML theme that outputs Markdown.
