Question

Is there a way for a Chrome extension to read properties from manifest.json? I’d like to be able to read the version number and use it in the extension.

You can just use chrome.runtime.getManifest() to access the manifest data – you don’t need to GET it and parse it.

var manifestData = chrome.runtime.getManifest();
console.log(manifestData.version);
console.log(manifestData.default_locale);
