# app
|
||
|
||
The `app` module is responsible for controlling the application's life time.
|
||
|
||
The example of quitting the whole application when the last window is closed:
|
||
|
||
```javascript
|
||
var app = require('app');
|
||
app.on('window-all-closed', function() {
|
||
app.quit();
|
||
});
|
||
```
|
||
|
||
## Event: will-finish-launching
|
||
|
||
Setup crash reporter and auto updater here.
|
||
|
||
## Event: finish-launching
|
||
|
||
Do final startup like creating browser window here.
|
||
|
||
## Event: window-all-closed
|
||
|
||
Emitted when all windows have been closed.
|
||
|
||
This event is only emitted when the application is not going to quit. If a
|
||
user pressed `Cmd + Q`, or the developer called `app.quit()`, atom-shell would
|
||
first try to close all windows and then emit the `will-quit` event, and in
|
||
this case the `window-all-closed` would not be emitted.
|
||
|
||
## Event: will-quit
|
||
|
||
* `event` Event
|
||
|
||
Emitted when all windows have been closed and the application will quit.
|
||
Calling `event.preventDefault()` will prevent the default behaviour, which is
|
||
terminating the application.
|
||
|
||
See description of `window-all-closed` for the differences between `will-quit`
|
||
and it.
|
||
|
||
## Event: open-file
|
||
|
||
* `event` Event
|
||
* `path` String
|
||
|
||
Emitted when user wants to open a file with the application, it usually
|
||
happens when the application is already opened and then OS wants to reuse the
|
||
application to open file.
|
||
|
||
You should call `event.preventDefault()` if you want to handle this event.
|
||
|
||
## Event: open-url
|
||
|
||
* `event` Event
|
||
* `url` String
|
||
|
||
Emitted when user wants to open a URL with the application, this URL scheme
|
||
must be registered to be opened by your application.
|
||
|
||
You should call `event.preventDefault()` if you want to handle this event.
|
||
|
||
## app.quit()
|
||
|
||
Try to close all windows. If all windows are successfully closed, the
|
||
`will-quit` event will be emitted and by default the application would be
|
||
terminated.
|
||
|
||
This method guarantees all `beforeunload` and `unload` handlers are correctly
|
||
executed. It is possible that a window cancels the quitting by returning
|
||
`false` in `beforeunload` handler.
|
||
|
||
## app.terminate()
|
||
|
||
Quit the application directly, it will not try to close all windows so cleanup
|
||
code will not run.
|
||
|
||
## app.getVersion()
|
||
|
||
Returns the version of current bundle or executable.
|
||
|
||
## app.commandLine.appendSwitch(switch, [value])
|
||
|
||
Append a switch [with optional value] to Chromium's command line.
|
||
|
||
**Note:** This will not affect `process.argv`, and is mainly used by developers
|
||
to control some low-level Chromium behaviors.
|
||
|
||
## app.commandLine.appendArgument(value)
|
||
|
||
Append an argument to Chromium's command line. The argument will quoted properly.
|
||
|
||
**Note:** This will not affect `process.argv`.
|
||
|
||
## app.dock.bounce([type])
|
||
|
||
* `type` String - Can be `critical` or `informational`, the default is
|
||
* `informational`
|
||
|
||
When `critical` is passed, the dock icon will bounce until either the
|
||
application becomes active or the request is canceled.
|
||
|
||
When `informational` is passed, the dock icon will bounce for one second. The
|
||
request, though, remains active until either the application becomes active or
|
||
the request is canceled.
|
||
|
||
An ID representing the request would be returned.
|
||
|
||
**Note:** This API is only available on Mac.
|
||
|
||
## app.dock.cancelBounce(id)
|
||
|
||
* `id` Integer
|
||
|
||
Cancel the bounce of `id`.
|
||
|
||
**Note:** This API is only available on Mac.

|
||
