NW When starting the application, first to read the Package.json file, initialize the basic properties, let us look at the full parameters of Package.json. Each parameter configuration is marked with a comment.

In the above configuration, main and name are required properties. Other simple and straightforward to read the comments directly, Bo main talk about a few more difficult to understand the parameters configuration.

(1) "Node-main" configuration: Specify a JS file, the JS file is the first to run the program when the file, in the Node-main script can also access the global "Window" object, which points to the Dom window, but if the page navigation has changed, The Window object accessed is also changed. Because it executes before the DOM is loaded, the "window" object cannot be used until the page has finished loading. Also, in the DOM page, you can get node-main information through Process.mainmodule.

(2) "single-instance" configuration: Simply speaking, whether to allow multiple NW applications to be opened at the same time.

(3) "Kiosk" configuration: If the configuration is set to Ture, it is displayed in full screen mode and the block off button, that is, the display will remain in the NW application display interface, similar to the bank queue waiting for business of the ticket machine interface.
