rehype plugin to prevent a network request to the favicon when there is none.


What is this?

This package is a plugin that inserts an empty favicon image, when there is none referenced, to prevent a network request.

When should I use this?

You can use this plugin when you don’t have a favicon.ico at the root of your server, and want to prevent browsers sending out a network request to find it.

This plugin increases the size of the HTML, but prevents a round trip to the server by inserting an empty favicon.

HTML is parsed according to WHATWG HTML (the living standard), which is also followed by all browsers.

Syntax tree

The syntax tree used is hast.


This package is fully typed with TypeScript.


Projects maintained by the unified collective are compatible with maintained versions of Node.js.

When we cut a new major release, we drop support for unmaintained versions of Node. This means we try to keep the current release line, rehype-prevent-favicon-request@^4, compatible with Node.js 16.


As rehype works on HTML and improper use of HTML can open you up to a cross-site scripting (XSS) attack, use of rehype can also be unsafe. Use rehype-sanitize to make the tree safe.
