It’s known for some time that Microsoft has plans for getting Chrome extensions on board for Edge browser, and it seems the company has quietly made the tool available for the developers in the Windows Store. Know as the Microsoft Edge Extension Toolkit. It creates the necessary JSON manifest entries and bridges the chrome—APIs to the browser.
This, of course, works with Windows 10 Anniversary Update on Build 14393.10, which is now in the public domain and henceforth will make it easy for Chrome extension developers to get on board with minimum code changes. The listing on the store says:
This toolkit allows developers to convert a Chrome extension to run on Microsoft Edge in the Windows 10 Anniversary Update (14393.10) edition. The tool creates the necessary JSON manifest entries and bridges the chrome—APIs to the browser. APIs supported on Microsoft Edge, poly-filing where necessary.
The extension toolkit is pretty straight forward. One installed and loaded, you will need to point to the source of extensions you developed for chrome. It then reveals all files and folders and maps Chrome APIs to the Edge browser. You have the option to save and revalidate to cross-check for any errors.
Remember, this is only for developers, and you cannot download an extension from Chrome Store and then covert. They have compiled source codes meant for execution. It’s only for developers.
