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.
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 yourpackage.json
devDependencies
section:"docjs-theme": "my-gh-username/reponame"
. That way when you install dependencies, your new theme will be in the projectsnode_modules
folder. -
In the folder you created, replace
require('../')
on lines 8 and 9 ofindex.js
withrequire('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"
If a documentation.yml file is used to establish a table of contents for your documentation, small changes to the default style can be made via a <style> element in the documentation.yml file.
For example, if you have you have a section header and text to describe the section, you can put it at the same level of the text as shown below:
- name: Section Header Name
description: |
<head>
<style>
h2{
color:black;
}
code.black{
background-color: #295377;
overflow: hidden;
padding: 0.5rem;
color: white;
font: 0.8rem Inconsolata, monospace;
width:100%;
}
</style>
</head>
### Sub Section header
Text that describes the section and sub-section here.
Any changes to elements and classes that also exist in the standard theme will be overwritten by what is in the documentation.yml. This opens up the possibility of the same CSS being defined twice, which can be confusing and is not best practice. However, it is easy to change HTML style this way. Recommend only using classes defined this way that do not exist in the standard documentation.js theme.
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.
