javascript - Ensuring user permits Microphone access before firing event in React app - Stack Overflow

I have created a React ponent with a microphone button that:

• OnMouseDown => User begins recording audio
• OnMouseUp => Audio recording ends

In other words, as long as the button is held down, the user can continue recording (similar to WhatsApp / other apps voice-message feature).

My issue is, on the first time the page appears on a user's desktop, the moment they click the button to record, Chrome pops up a dialog asking the user permission to access the microphone.

The problem with that is that, in order to click "ok" on the dialog, the user has to Mouse-up on the button which is causing an error due to the recording element not having been created yet.

Is there a way to make it such that OnMouseDown =>

1. Make sure user has given permission to access microphone
2. If not, ask for permission without firing off the recording sequence yet

From the research I've done, it seems I need to do something along the lines of:

const onMouseDown = async () => {
    await navigator.mediaDevices.getUserMedia({ audio: true });
    // rest of code
};

But it seems that that actually starts a recorder (and there won't be any corresponding MouseUp event to end it) and all I want to do with this portion of the code is:

• Nothing if user has already given permission
• Ask for permission if the first time and exit event to ensure microphone is enabled for the next time the user clicks.

In case someone gets caught up with the same issue, what I ended up having to do was create a global variable checking if microphone permissions were granted (I did this via Redux). Then, when the ponent first mounts, I run an action that:

1. Checks the microphone permissions against the global variable
2. If not granted / denied, then it runs the following:

    export const checkMicrophonePermissions = () => async dispatch => {
          let retval = false;
    
          await navigator.mediaDevices.getUserMedia({ audio: true })
            .then(stream => retval = true)
            .catch(err => retval = false);
    
          dispatch({
              type: MICROPHONE_ACCESS,
              payload: retval
          });
      }

Basically, it will run as the page loads the first time and pop-up a dialog asking the user to permit microphone access and sets the global variable relating to MICROPHONE_ACCESS to true / false based upon the user's reply.
