Miscellaneous Components
There are several miscellaneous components that don’t fit into other categories. These are:
They are described in more detail below.
startup
The startup component is the one that you would use if you are not
using a combined component, but are using
the load array to specify the components you want to load. Like a
combined component, you would load this directly via a <script> tag,
as in
<script type="text/javascript" id="MathJax-script" async
src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/startup.js">
</script>
This is the component that manages the global MathJax object.
It is responsible for creating the needed objects (like the input and
output jax), and for adding the typesetting and conversion methods
described in the Typesetting and Converting Mathematics section.
See the Startup Options section for information about configuring this component.
ui/safe
The ui/safe component is intended for use in situations where your
readers will be allowed to enter mathematical notation into your pages
themselves, such as a question-and-answer site, or a blog with user
comments. It filters the mathematics on the page to make sure that
certain values within the mathematics are not misused by the reader to
cause problems on your page. For example, the \href macro
normally could be used to insert javascript: URLs into the page;
the ui/safe extension can be used to prevent that.
See the Safe Extension Options section for more information on what is filtered and how to control the level of filtering being performed. See Typesetting User-Supplied Content for additional details.
adaptors/liteDOM
The adaptors/liteDOM component implements an alternative to the browser DOM that can be used to parse HTML pages outside of a browser. This can be used in Node applications that don’t have access to a browser DOM, or in webworkers that can’t access the document DOM.
core
The core component includes the code that is required for all other components, including the base classes for input and output jax, math documents, math items within those documents, DOM adaptors, and so on. This component is loaded automatically when needed, so you don’t usually have to load it yourself. But you can include it if you are creating your own combined component.
loader
The loader component contains the code needed to load other components. It is included automatically by the startup component, but if you don’t want the features created by the startup module, you can use the loader component instead to load the MathJax component you need. You can even use it as a general loader for other javascript, if you want.
See the Loader Options section for information about configuring this component.
