|
| 3 | When you want to fire an event no matter how a process exits:
|
| 4 |
|
| 5 | * reaching the end of execution.
|
| 6 | * explicitly having `process.exit(code)` called.
|
| 7 | * having `process.kill(pid, sig)` called.
|
| 8 |
|
| 9 | Use `signal-exit`.

|
| 12 | var onExit = require('signal-exit')
|
| 13 |
|
| 14 | onExit(function (code, signal) {
|
| 15 | console.log('process exited!')
|
| 16 | })
|
