Extjs5 app. js buffer settings

After the official version of Extjs5 was released in June 2, The sencha recommended that the project compile be used to publish the application. during the development process, the sencha app watch command can be used to generate the service. Each time a js class is created, ctrl + C is required, and then re-enter the sencha app watch command. Otherwise, the new class will not take effect. when the project is finally released, the sencha app build will automatically compile the project, then deploy the compiled project to the server, and everything is not good at this time. You will find that every time you access the application, the compiled app. all js files will be downloaded again, which is very slow. Is there any way to speed up? In other words, can I directly buffer app. js? The answer is yes. Tracking the sencha code will find that a bootstrap. js file has a disableCaching attribute. You only need to set disableCaching to false.
