Make a synchronous function have a timeout
npm install function-timeout> Make a synchronous function have a timeout
This can be useful if you accept external data and want to ensure processing it does not take too long.
The timeout only works in Node.js. When used in a browser, the function will be wrapped, but never time out.
I have a different package to prevent ReDoS for regexes.
``sh`
npm install function-timeout
`js
import functionTimeout, {isTimeoutError} from 'function-timeout';
const generateNumbers = count => {
// Imagine this takes a long time.
};
const generateNumbersWithTimeout = functionTimeout(generateNumbers, {timeout: 100});
try {
console.log(generateNumbersWithTimeout(500));
} catch (error) {
if (isTimeoutError(error)) {
console.error('Timed out');
} else {
throw error;
}
}
`
Returns a wrapped version of the given function that throws a timeout error if the execution takes longer than the given timeout.
#### options
Type: object
##### timeout?
Type: number` (integer)
The time in milliseconds to wait before timing out.
Keep in mind that execution time can vary between different hardware and Node.js versions. Set a generous timeout to avoid flakiness.
Returns a boolean for whether the given error is a timeout error.
