How to combine with other node command about concurrently HOT 1 CLOSED

The exit code of concurrently will be 1 so bash never runs the command after &&.
If it is really such a simple use case, I'd probably go without concurrently and instead use the command timeout, for example.
If there are other reasons for you to stay with concurrently, you could adjust the command to:

# to always run "npm run three"
npm run one && concurrently -k  "node ./timeout.js" "npm run two"; npm run three

# or to run "npm run three" only if concurrently wasn't successful (timeout reached and therefore killed)
npm run one && concurrently -k  "node ./timeout.js" "npm run two" || npm run three
