Question

I want to implement audio recording functionality in my angular app using media recorder but I am getting the following error:

error TS2304: Cannot find name 'MediaRecorder'

Does anyone has solution for this.

Answer 1

Assuming you are using Media Recorder

Go to your tsconfig file if you dont have one create by npx tsc --init

{
  "compilerOptions": {
    // ......your other options
    "lib": ["dom", "dom.iterable", "esnext"]
  }
}
