How to set value ONLY ONCE in chrome extensions using chrome.storage.local



I am making a Chrome extension that features a login flow using an existing in house authentication system. I make a get query, then the system redirects to the auth URL, then returns the user to a white-listed URL.
Right before the user is sent to the authentication URL to do its business, I want to grab their location and store it, so after they are logged in and returned to the white-listed URL, they can then be redirected to where they kicked off the login flow.



I am using chrome.storage.local to set location and get location, but due to they async nature of this call, I'm getting an infinite loop.



Any suggestions on how to just set and get once and/or hack the async nature of chrome storage?

Before we started uploading we made sure the right COM-port was selected in the Arduino IDE and that also the right type of Arduino was selected. The Arduino Mega 2260. Then we started with compiling the firmware and then uploading it to the Mega, Somewhere in between that moment the IDE freezed and crashed. As a response we removed the USB cable that was connected from the PC uploading the firmware onto the Arduino Mega, (This was a st...

Clash Royale CLAN TAG #URR8PPP Visual Studio Code: How to configure includePath for better IntelliSense results so I am a complete beginner to using Visual Studio Code and I have no clue what I am doing. I've searched around (maybe not enough), but I cant find just a simple explanation for someone like me on how to configure the c_cpp_properties.json file that I am redirected to whenever I click on the yellow lightbulb next to a line that is underlined with a green squiggle.

Clash Royale CLAN TAG #URR8PPP C++ virtual function: Base class function is called instead of derived I have following code snippet: using namespace std; class base { public: virtual void print(char a){ std::cout<<" Base "<<std::endl;} }; class derived :public base { public: void print(floata) {std::cout<<" Derived "<<std::endl;} }; int main() { base* d = new derived; d->print(1.5); return 0; } Output is "base" Why output is coming from base function and not from derived one By clicking "Post Your Answer", you acknowledge that you have read our updated terms of service, privacy policy and cookie policy, and that your continued use of the website is subject to these policies.
