4.2.0

• Merge onCancelList and finallyList
• Add isCancelablePromise util
• Migrate to Typescript and improve umd/esm outputs

4.1.0

• Prepare release without commit
• Cancel cancelable promise returned by a then/catch callback

Consider this example:

const { CancelablePromise } = require('cancelable-promise');

const promise1 = new CancelablePromise((resolve, reject, onCancel) => {
  const timer = setTimeout(() => {
    console.log('resolve promise1');
    resolve();
  }, 1000);
  const abort = () => {
    clearTimeout(timer);
  };
  onCancel(abort);
});

const promise2 = promise1.then(() => {
  const promise3 = new CancelablePromise((resolve, reject, onCancel) => {
    const timer = setTimeout(() => {
      console.log('resolve promise 3');
      resolve();
    }, 1000);
    const abort = () => {
      clearTimeout(timer);
    };
    onCancel(abort);
  });
  return promise3;
});

setTimeout(() => {
  console.log('cancel promise 2');
  promise2.cancel();
}, 1500);

Before this release, output was:

resolve promise1
cancel promise 2
resolve promise 3

Now if you return a cancelable promise in a then/catch callback, it will cancel it too when you are canceling the parent promise. Output will be:

resolve promise1
cancel promise 2

const promise = new CancelablePromise((resolve, reject, onCancel) => {
  const worker = new Worker('some-script.js');

  onCancel(() => {
    worker.terminate();
  });

  worker.onmessage = (event) => resolve(event.data);
  worker.onerror = (error) => reject(error);
});

promise.cancel(); // It will execute the callback passed to onCancel

let worker;
const promise = cancelable(
  new Promise((resolve, reject) => {
    worker = new Worker('some-script.js');
    worker.onmessage = (event) => {
      resolve(event.data); // never executed
    };
    worker.onerror = (error) => {
      reject(error); // never executed
    };
  })
)
  .then(() => {
    console.log('never logged');
  })
  .finally(
    () => {
      console.log('executed');
      if (worker) {
        worker.terminate();
        worker = null;
      }
    },
