Override WinJS promises with native promises as a Chrome Extension content script?

If you are working with TypeScript and using WinJS promises in your Chrome Extension content script, you might come across situations where you need to override WinJS promises with native promises. In this blog post, we will explore how you can achieve this.

Solution 1: Wrapping WinJS Promises

The first solution involves wrapping the WinJS promises with native promises. This can be done by creating a function that takes a WinJS promise as an argument and returns a native promise.


function wrapWinJSPromise(winJSPromise) {
  return new Promise((resolve, reject) => {
    winJSPromise.then(resolve, reject);
  });
}

// Usage
const winJSPromise = new WinJS.Promise((resolve, reject) => {
  // Your WinJS promise code here
});

const nativePromise = wrapWinJSPromise(winJSPromise);

By wrapping the WinJS promise with a native promise, you can now use native promise methods such as then, catch, and finally.

Solution 2: Converting WinJS Promises

The second solution involves converting WinJS promises to native promises. This can be done by creating a function that takes a WinJS promise as an argument and returns a new native promise.


function convertWinJSPromise(winJSPromise) {
  return new Promise((resolve, reject) => {
    winJSPromise.done(resolve, reject);
  });
}

// Usage
const winJSPromise = new WinJS.Promise((resolve, reject) => {
  // Your WinJS promise code here
});

const nativePromise = convertWinJSPromise(winJSPromise);

By converting the WinJS promise to a native promise, you can now use native promise methods such as then, catch, and finally.

Now that you know how to override WinJS promises with native promises, you can easily work with TypeScript in your Chrome Extension content script without any limitations.
