React Native Environment Setups

There is a different alternative for React Native environment setup (installation), depends upon the operating system you use.

The instructions are quite different for each development and target operating system.
In this tutorial, we will use Windows as a development operating system and Android as a target operating system.

Developing app using React Native framework requires Node, React Native command line interface, Python2, JDK, and Android Studio.
Here, we are using a favorite package manager Chocolatey for Windows. Using this, we can install a recent version of Python, and Java SE Development Kit (JDK).

Steps to Setup React Native Environment

1. Visit Chocolatey, and click "Install Chocolatey Now" it open another URL.

How I Reduced the Size of My React Native App by 85%

How and Why You Should Do It I borrowed 25$ from my friend to start a Play Store Developer account to put up my first app. I had already created the app, created the assets and published it in the store. Nobody wants to download a todo list app that costs 25mb of bandwidth and another 25 MB of storage space. So today I am going to share with you how I reduced the size of Tet from 25 MB to around 3.5 MB. Size Matters Like any beginner, I wrote my app using Expo, the awesome React Native platform that makes creating native apps a breeze. There is no native setup, you write javascript and Expo builds the binaries for you. I love everything about Expo except the size of the binaries. Each binary weighs around 25 MB regardless of your app. So the first thing I did was to migrate my existing Expo app to React Native. Migrating to React Native react-native init  a new project with the same name Copy the  source  files over from Expo project Install all de...

React Native - Text Input

In this chapter, we will show you how to work with  TextInput  elements in React Native. The Home component will import and render inputs. App.js import React from 'react' ; import Inputs from './inputs.js' const App = () => { return ( < Inputs /> ) } export default App Inputs We will define the initial state. After defining the initial state, we will create the  handleEmail  and the  handlePassword  functions. These functions are used for updating state. The  login()  function will just alert the current value of the state. We will also add some other properties to text inputs to disable auto capitalisation, remove the bottom border on Android devices and set a placeholder. inputs.js import React , { Component } from 'react' import { View , Text , TouchableOpacity , TextInput , StyleSheet } from 'react-native' class Inputs extends Component { state = { ...
