pm2 Single Page Application flag --spa throws 'unknown option' error

Question

I am using pm2 (5.1.2) and serve (13.0.2) to deploy a Node.js app. When I run the following:

pm2 serve build 8080 --spa

I receive the following error:

error: unknown option '--spa'

Is the flag deprecated? What could be causing this?

Answer 1

For pm2 there needs to be a space between -- and flags. The correct format is:

pm2 serve build 8080 -- spa
