How to match the same domain with multiple extensions in Chrome extension?

Question

So, I am working on a Chrome extension that needs to be activated on any site with the domain example.extension where extension can be anything(.com, .de etc.).

I have a content script and in the manifest.json I included all the domain names listed one after another:

"content_scripts": [{
    "js": ["content.js"],
    "matches": ["https://www.example.com/*","https://www.example.de/*"]
  }]

But how could I write something that matches example.* instead of enumerating all of them? Note that I tried something like this and it does not work:

 "content_scripts": [{
    "js": ["content.js"],
    "matches": ["https://www.example*"]
  }]

Answer 1

These are 2 options:

First option: You make use of the include_globs in the manifest as shown here

    "content_scripts": [{
           "js": ["content.js"],
            "matches": [ "*://*/*" ],
            "include_globs": [
                "*://*.example.*/*",
            ]
        }]

2nd Option: You can change your content script to check if the target URL matches www.example.*:

if (window.location.host.startsWith('www.example')){
   //content script code
}
