Session

Nano framework has inbuilt session module, it helps to store key-value information in app session that gets cleared when app closed/killed.

Storing and reading data from session:

All the methods like onPress, onLongPress, onStart, onResume, onPause and onEnd in framework has access to moduleParams parameter that has all the available modules, you can use session module from it like below.

For example, below is the code to store and delete key-value data using setValue, deleteValue and deleteAllValues method from session module.

const buttonPress = {
  component: NANO.BUTTON,
  value: 'CLICK TO SAVE DATA TO SESSION',
  onPress: ({ moduleParams }) => {
        
        // set Value
        moduleParams["session"].setValue("name", "value") 

        // delete Value
        moduleParams["session"].deleteValue("name")
        
        // delete All values
        moduleParams["session"].deleteAllValues()
        


  }
};

const screen = {
  name: 'HomeScreen',
  screen: {
    h1: [buttonPress]
  }
};

You can read data from session in any screen using getValue and getAllValues like below.

const text2 = {
  component: NANO.TEXT,
  value: "I AM IN ANOTHER SCREEN",
};

const screen = {
  name: 'AnotherScreen',
  screen: {
    h1: [text],
  },
  onStart: ({moduleParams}) => {
      
      // read single value
      console.log(moduleParams["session"].getValue("name"))

      // read all stored values
      console.log(moduleParams["session"].getAllValues())
    
  }
};
