Global state in React Native

Question

I am developing a React Native application.

I want to save the user id of the person who is logged in and then check if the user is logged in in every single compone

Answer 1

I usually do globals like this:

I creat an globals.js

module.exports = {
  USERNAME: '',
};

Something like that to store the username then you just need to import :

GLOBAL = require('./globals');

And if you wanna store the Data, lets say you want to save the username just do :

var username = 'test';
GLOBAL.USERNAME = username;

And there you go , you just need to import GLOBAL on the pages you want and use it, just use if (GLOBAL.username == 'teste').
