Description

Feature request

Allow the public path to be a function.

What is the expected behavior?

It should call the function everytime instead of +.

What is motivation or use case for adding/changing the behavior?

https://developer.chrome.com/docs/extensions/reference/manifest/web-accessible-resources

There is an option called "use_dynamic_url" in Chrome extension.

Normally, resources can be accessed via URLs like chrome-extension://odhaijconicohjickedigmojjmeblalp/my-file.js, but with this option on (this options improves security and privacy), it has to be chrome.runtime.getURL('my-file.js'), and the return URL becomes chrome-extension://21f06455-6875-452b-8132-01268c50ba0e/my-file.js where the UUID is random every time.

It will be easier to support this use case in a plugin (awesome-webextension/webpack-target-webextension#47) if the public path can be a function.

How should this be implemented in your opinion?

Add a new webpack internal function:

__webpack__require__.xxx = function (path) {
    if (typeof __webpack_require__.p == 'function') return __webpack_require__.p(path)
    return __webpack_require.p + path
}

And replace all direct use of RuntimeGlobals.publicPath to call this helper function.

Are you willing to work on this yourself?
yes
