How to run ionic in the background

问题:

I am trying to run ionic serve in the background so I can test it via my rails app on circle ci. I thought I could do it with:

nohup bash -c "ionic serve --nolivereload --nobrowser &"

But unfortunately it doesn't work. Does anyone know how to run it in the background?

回答1:

You could use screen:

screen -d -m -L ionic serve --nolivereload --nobrowser

回答2:

Why do you want it to run in background on CI ?

It should be ok to run the command directly before your test:

ionic serve --nolivereload --nobrowser &

Your CI should kill all the triggered process once its done...

Update:

If your CI does not kill the triggered process, you could do something like this:

ionic serve --nolivereload --nobrowser &
ionicpid=$!
your_test_command_here
kill -15 $ionicpid

It should work on CI if all of these commands are in the same job.

On CircleCI I have found this setup to work well

machine:
  node:
    version: v7.4.0

test:
  pre:
    - npm run webdriver-update
    - ionic serve --nolivereload --nobrowser --port 8101:
        background: true
    - sleep 15

  override:
    - npm run e2e

Here's a method that actually works (sorry so late)

sleep 999999999 | ionic serve -b &

I think there's an easy way in ionic v3, but this works for v1
