npm i html-head-component

# or

yarn add html-head-component


In your JavaScript/TypeScript entry point:

import 'html-head-component';

You can also include the web component directly from



<script async src=""></script>

Then add the component in your HTML/JSX markup:

The custom component should be placed in the <body> tag. If you try to place it in the <head> the browser will explicitly move it in the <body> and you might experience issues with the rest of the elements in the <head>.

Using the data attribute

		"tag": "title",
		"content": "Title"
		"tag": "meta",
		"name": "author",
		"content": "Scriptex"
		"tag": "link",
		"rel": "stylesheet",
		"href": "./style.css"

Using the src attribute

<html-head-component src="./data.json"></html-head-component>

Usage details

The web component accepts two attributes:

  • src which is a valid path to a JSON file containing array of objects.
  • data which is a valid JSON string which represents an array of objects.

Only one of those attributes should be used. If both are used, the src attribute overwrites the data attribute.

Each object in the JSON array should have a tag property which specifies the HTML element which will be rendered.

The rest of the properties in the object specify the attributes and their content in key:value pairs (attribute:attribute-content).

There are several exceptions:

  1. The document title's content is rendered as innerHTML of the <title> tag.
  2. Each style tag's content property will be rendered as innerHTML of the <style> tag.
  3. Each script tag's content property will be rendered as innerHTML of the <script> tag.
  4. Each noscript tag's content property will be rendered as innerHTML of the <noscript> tag.

React with TypeScript

If you're using React with TypeScript, you need to extends the JSX IntrinsicElements interface so TypeScript knows that the html-head-component element exists.

You can do so in a custom.d.ts file in your project's root folder. Don't forget to add that file in your tsconfig.json!

declare namespace JSX {
	interface IntrinsicElements {
		html-head-component: any;

Full example
