|
When you want to fire an event no matter how a process exits: |
|
|
|
* reaching the end of execution. |
|
* explicitly having `process.exit(code)` called. |
|
* having `process.kill(pid, sig)` called. |
|
* receiving a fatal signal from outside the process |
|
|
|
Use `signal-exit`. |
|
|
|
```js |
|
var onExit = require('signal-exit') |
|
|
|
onExit(function (code, signal) { |
|
console.log('process exited!') |
|
}) |
|
``` |
|
|
|
## API |
|
|
|
`var remove = onExit(function (code, signal) {}, options)` |
|
|
|
The return value of the function is a function that will remove the |
|
handler. |
|
|
|
Note that the function *only* fires for signals if the signal would |
|
cause the process to exit. That is, there are no other listeners, and |
|
it is a fatal signal. |
|
|
|
## Options |
|
|
|
* `alwaysLast`: Run this handler after any other signal or exit |
|
handlers. This causes `process.emit` to be monkeypatched.
