NodeJS SIGKILL不存在并引发错误

Question

I have implement in my node js app restart of node using terminal:

killall -9 node

i try to detect SIGKILL before node is actually killed with this code:

process.on('SIGKILL', function() {
    /* DO SOME STUFF HERE */

    process.exit()
})

but problem is that node does not recognize SIGKILL and throws an error while compiling...so my question is does anyone have idea how to detect killall -9 command in node before node app is terminated so that i can do some stuff before killing node app?

I read on node web page that SIGKILL is reserved and is not used so i need alternative way how to detect killall -9 command.... thanks

Problem solved using:

killall -2 node

-2 define signal interrupt like Ctrl+C so node triggers SIGINT before exits because -2 simulates Ctrl+C...and voila problem solved.
