Sometimes, we want to add a response timeout with Express.js and Node.js.
In this article, we’ll look at how to add a response timeout with Express.js and Node.js.
How to add a response timeout with Express.js and Node.js?
To add a response timeout with Express.js and Node.js, we can use the connect-timeout module.
To install it, we run
npm i connect-timeout
Then we use it by writing
const timeout = require('connect-timeout');
const haltOnTimedout = (req, res, next) => {
if (!req.timedout) {
next();
}
}
app.use(timeout(120000));
app.use(haltOnTimedout);
to define the haltOnTimeout function.
We check if the request has timed out with req.timedout.
If it’s false, then we call next to call the next middleware.
And we add the middleware returned by timeout called with the request timeout in milliseconds and the halfOnTimedout function with app.use in the order they’re listed to lets us set a timeout for all requests to 120000 milliseconds.
Conclusion
To add a response timeout with Express.js and Node.js, we can use the connect-timeout module.
