Variable stopReadonly

A Symbol that can be returned by a beforeRetry hook to stop the retry. This will also short circuit the remaining beforeRetry hooks.

Note: Returning this symbol makes Ky abort and return with an undefined response. Be sure to check for a response before accessing any properties on it or use optional chaining. It is also incompatible with body methods, such as .json() or .text(), because there is no response to parse. In general, we recommend throwing an error instead of returning this symbol, as that will cause Ky to abort and then throw, which avoids these limitations.

A valid use-case for ky.stop is to prevent retries when making requests for side effects, where the returned data is not important. For example, logging client activity to the server.

Example

import ky from 'ky';

const options = {
    hooks: {
        beforeRetry: [
            async ({request, options, error, retryCount}) => {
                const shouldStopRetry = await ky('https://example.com/api');
                if (shouldStopRetry) {
                    return ky.stop;
                }
            }
        ]
    }
};

// Note that response will be `undefined` in case `ky.stop` is returned.
const response = await ky.post('https://example.com', options);

// Using `.text()` or other body methods is not supported.
const text = await ky('https://example.com', options).text();
