I'm going to open a PR:

• yes

Description:

If manifest.json is provided, if something in entries.contentScript is not in the manifest.json#content_scripts.js is is silently removed.

webpack-extension-reloader/src/utils/manifest.ts

Lines 41 to 49 in 4f9aa5e

	const contentEntries: unknown = content_scripts
	? flatMapDeep(Object.keys(webpackEntry), entryName =>
	content_scripts.map(({ js }) =>
	js
	.map(contentItem => contentItem.replace(toRemove, ""))
	.filter(contentItem => contentItem === entryName),
	),
	)
	: null;

I have a situation similar to here where I need to access the window object. This requires injecting a separate entry point like so:

export default function injectScript(filePath, tag) {
  var node = document.getElementsByTagName(tag)[0]
  var script = document.createElement('script')
  script.setAttribute('type', 'text/javascript')
  script.setAttribute('src', filePath)
  node.appendChild(script)
}

injectScript(chrome.extension.getURL('content-script.js'), 'body')

  "content_scripts": [
    {
      "matches": ["foo.com"],
      "css": ["style.global.css", "style.css"],
      "js": ["content-script-injector.js"],
      "all_frames": false
    }
  ],

This functionality prevents reloads when content-script.js is changed.

Maybe adding another option to IEntriesOption to specify a file that will be always injected with the middleware.
