Webext-polyfill-kinda NPM

webext-polyfill-kinda

Super-lightweight Promised wrapper around chrome.* APIs to be used in modules.

✅ Use this module when publishing your own micro-modules. This avoids having to import webextension-polyfill as a sub-dependency.

❌ Do not use this module if you need promised APIs directly in your extension. webextension-polyfill is much safer.

⚠️ This package isn't completely safe to use because it blindly wraps the chrome.* APIs whether it supports them or not.

Please test your module in every browser before assuming it works, or prefer webextension-polyfill.

Install

npm install webext-polyfill-kinda

Usage

import chromeP from 'webext-polyfill-kinda';

(async () => {
	// Cases where the API works
	const currentTab = await chromeP.tabs.getCurrent();
	const options = await chromeP.storage.local.get('options');

	// Do not use `chromeP` when dealing with listeners, it doesn't make sense. Use the native `chrome.*` API
	chrome.tabs.onUpdated.addListener(listener);
})();

TypeScript Usage

chromeP will reuse the global chrome type if it exists. The suggested solution is to also install this, the types will be automatically available.

npm install @types/chrome --save-dev
