# Short Circuit Concurrently When Process Fails
|
|
|
|
In [Run Multiple Node Scripts
|
|
Concurrently](run-multiple-node-scripts-concurrently.md), I showed how we can
|
|
get all the essential processes of our web app running concurrently in
|
|
development using the `concurrently` package.
|
|
|
|
But what happens when there is an error and one of them exits early instead of
|
|
continuing to run?
|
|
|
|
Well, the rest of the processes under the `concurrently` umbrella continue to
|
|
run as if nothing has happened. In fact, if there is enough output, you might
|
|
even miss that that one process failed since the error gets quickly pushed off
|
|
the screen.
|
|
|
|
If we need every process running for our app to work, then it would be better
|
|
to have the whole set of concurrent processes short circuit and exit early if
|
|
one fails. We can do that by giving `concurrently` the `--kill-others-on-fail`
|
|
flag.
|
|
|
|
```json
|
|
{
|
|
"scripts": {
|
|
"dev": "concurrently --kill-others-on-fail \"npm:dev:*\"",
|
|
"dev:next": "next dev",
|
|
"dev:inngest": "pnpx inngest-cli@latest dev",
|
|
"dev:mailhog": "mailhog",
|
|
}
|
|
}
|
|
```
|
|
|
|
See the [Usage
|
|
section](https://github.com/open-cli-tools/concurrently?tab=readme-ov-file#usage)
|
|
of the docs for more details.
