Custom module

You can create your own module according to your needs and use it from moduleParams from any method.

Here is a simple example to create a simple custom module called Addition that takes two numbers and add them.

Addition.js

class Addition {
  constructor() {}
  add(num1, num2) {
    return num1 + num2
  }
}

var addition = null;

const getAddition = () => {
  if (addition == null) {
    addition = new Addition();
  }
  return addition;
};

export default getAddition;

And include the Addition in RNNano componenent like below

import {RNNano} from  'react-native-nano';
import Addition from 'Addition'

const customModules =  {
    "addition" : Addition
}


const  App = () => {
    return <RNNano screens={[screen]} customModules={customModules} />;
};
export  default  App;

And use the addition module from any method like below.

const buttonPress = {
  component: NANO.BUTTON,
  value: 'CLICK ME TO ADD',
  onPress: ({ moduleParams }) => {
       const added =  moduleParams["addition"].add(1, 2) 
       console.log(added)
  }
};

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