Question

Как вариант типа того: const getCancellablePromise = (promise, isCanceled) =>

new Promise((resolve, reject) => {
promise.then(result => (
isCanceled() ? reject() : resolve(result)
));
});

class Test extends React.Component {

...

componentDidMount() {
this.isMounted_ = true;
}

componentWillUnmount() {
this.isMounted_ = false;
}

test() {
getCancellablePromise(
this.props.someAction(),
() => !this.isMounted_
).then(
() => {
// make smth
},
() => { /* canceled */ }
);
}
...

}
