easy-html-injector is a simple Node module that allows you to inject HTML elements into an HTML string. The package exports a single function inject(html: string, element: HtmlElement) that takes an HTML string and an object representing an HTML element to be injected, and returns the modified HTML string with the new element inserted at the specified position.

Installation

To install easy-html-injector, use pnpm, npm, or yarn:

pnpm add easy-html-injector

npm install easy-html-injector

yarn add easy-html-injector

Usage

First, import the inject function:

import { inject } from 'easy-html-injector';

The inject function takes two arguments:

html: A string containing the HTML that you want to modify.
element: An object representing the HTML element that you want to inject. The object has the following properties:
- parent: A string representing the parent element into which the new element will be injected. This can be 'head', 'body', or any other valid HTML element tag name.
- position: A string representing the position at which the new element will be inserted. This can be 'prepend' or 'append'.
- tag: A string representing the tag name of the new element.
- content (optional): A string representing the content to be inserted into the new element.
- attributes (optional): An object representing the attributes to be added to the new element. The keys of the object represent attribute names, and the values represent attribute values.

Here is an example usage:

const html = `
  <!DOCTYPE html>
  <html lang="en">
    <head>
      <title>My page</title>
    </head>
    <body>
      <h1>Hello, world!</h1>
    </body>
  </html>
`;

const newElement = {
  parent: 'head',
  position: 'prepend',
  tag: 'meta',
  attributes: {
    charset: 'utf-8',
  },
};

const modifiedHtml = inject(html, newElement);
console.log(modifiedHtml);

This will output:

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <title>My page</title>
  </head>
  <body>
    <h1>Hello, world!</h1>
  </body>
</html>
