App

Since v0.3.1

Synopsis

// Load native UI library
var gui = require('nw.gui');

// Print arguments
console.log(gui.App.argv);

// Quit current app
gui.App.quit();

Reference

argv

Get the command line arguments when starting the app.

fullArgv

Get all the command line arguments when starting the app. Because node-webkit itself used switches like --no-sandbox and --process-per-tab, it would confuse the app when the switches were meant to be given to node-webkit, so App.argv just filtered such switches (arguments' precedence were kept). You can get the switches to be filtered with App.filteredArgv.

dataPath

since v0.6.1

Get the application's data path in user's directory. Windows: %LOCALAPPDATA%/<name>; Linux: ~/.config/<name>; OSX: ~/Library/Application Support/<name> where <name> is the field in the manifest.

clearCache()

Since v0.6.0

Clear the HTTP cache in memory and the one on disk. This method call is synchronized.

closeAllWindows()

since v0.3.2

Send the close event to all windows of current app, if no window is blocking the close event, then the app will quit after all windows have done shutdown. Use this method to quit an app will give windows a chance to save data.

getProxyForURL(url)

since v0.6.3

Query the proxy to be used for loading url in DOM. The return value is in the same format used in PAC (e.g. "DIRECT", "PROXY localhost:8080").
