The function with which you are trying to use 'new' does not have a call or construct signature

How can I prevent the error from appearing in my console.log?

An error message - 'Cannot use 'new' with an expression whose type lacks a call or construct signature.' - keeps popping up.

var audioContext = new window.AudioContext();

Is there any other method to resolve this issue?

    var AudioContext = <any>window.AudioContext || <any>window.webkitAudioContext;
    var audioContext = new AudioContext();

Answer №1

Typically, these types of global APIs are not initially defined in the TypeScript Window interface. However, you can declare it on the window using declaration merging as shown below:

declare namespace window {
    const AudioContext:{
        new():AudioContext;
    }
}

After doing this, you will be able to use it just like:

var audioContext = new window.AudioContext();
