Check it out! https://www.curiosity-lab.net/ultimat... ==================================== ✅ Contents: ==================================== This AppGyver tutorial explains how to use variables in your AppGyver mobile application. You will learn to learn the different type of variables and how to you use them when you build an mobile application. What is a variable? A variable is a way of storing information in a computer program. Think of a variable like a container and the name of the variable as the label on the container which shows us what is inside. variable's scope A variable's scope determines where in a program a variable is available for use. A variable's scope is defined by where the variable is initialized or created. App Variables App variables exist in the global context of the app. When the app opens for the first time, or is closed and reopened, app variables are reset. App variables are available under the appVars namespace in formulas. Page Variables Page variables exist in the context of a single page. When a page is removed from the navigation stack, its page variables are reset. Page variables are available under the pageVars namespace in formulas. Page Parameters Page parameters can only be of the text type. Page parameters are read-only variables that can be set with the Open page flow function for the new page, e.g. ID of a product for a product details page. When the page is closed, page parameters are reset. Data Variables Data variables are like page variables, but their schema is defined by the data resource they are linked to. They also come with default logic that loads the associated data from the backend and stores it in the data variable. When a page is removed from the navigation stack, its data variables are reset. Data variables are available under the data namespace in formulas. Special variables System variables System variables define properties of the current app and the device its running on. They cannot be affected by the user directly, but change when the underlying property changes. For example, resizing your browser window will affect systemVars.dimensions.window.width, and systemVars.os will be different on Android vs. iOS. System variables are available under the systemVars namespace in formulas. Sensor variables Sensor variables store data collected by device sensors, such as GPS position or accelerometer values. Sensor variables are available under the sensorVars namespace in formulas. Source.
