Node Timeouts

An unresponsive service can be worse than a down one. It can tie up your entire system if not handled properly. All network requests should have a timeout.

Here’s how to add timeouts for popular Node packages. All have been tested. The default is no timeout, unless otherwise specified. Enjoy!

Also available for Ruby, Python, Go, and Rust
