Finding the location of a file within a published web component

I am currently working on a webcomponent where I need to include a link tag in the head section and set the href attribute to a folder within a node module.

At this stage, during the development of my component, my project structure looks like this:

https://i.stack.imgur.com/3IRw1.png

My goal is to add the fontawesome.css stylesheet to the head of my page. For this purpose, I have created the following script:

  constructor() {
    super();
    if (!this.isFontAwesomeLoaded()) {
      this.iclass = '';
      const fontEl = document.createElement('link');
      fontEl.rel = 'stylesheet';    
      fontEl.href = "./fontawesome/css/all.css";
      document.head.appendChild(fontEl);    
    }
  }

However, there is an issue with the path ./fontawesome/css/all.css when it reaches the head tag because the index.html file loading the script lacks the necessary folder in its project structure. Instead, upon reaching production, it needs to determine the absolute path to my module and then locate the fontawesome folder.

My question is: How can I obtain that path?

Answer №1

It is important to be mindful of certain things to avoid in web development:

  1. Avoiding external dependencies within web-components, especially large ones like fontawesome, as it contradicts the goal of reducing coupling.
  2. Using web-components without shadow-dom may not be ideal, and by incorporating fontawesome, the true potential of web-components is neglected.

There are several ways to address this issue:

  1. Extract the necessary parts from fontawesome's all.css and integrate them into your web-component.
  2. Clearly state in the component's documentation that it relies on fontawesome and instruct clients to provide it themselves.
  3. Utilizing a CDN (not recommended):
constructor() {
    super();
    if (!this.isFontAwesomeLoaded()) {
      this.iclass = '';
      const fontEl = document.createElement('link');
      fontEl.rel = 'stylesheet';    
      fontEl.href = "https://stackpath.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css";
      document.head.appendChild(fontEl);    
    }
}
