Getting Started

To get a local copy up and running follow these simple steps.

Prerequisites

Install latest npm version on your system.

• npm

  npm install npm@latest -g

  Check the version by running this command.

• npm version

  npm -v

  I used expo-cli for this project,if you want to build the project with expo install expo-cli on your system

• expo cli

  npm install --global expo-cli

If installation gives you error like this,

•     npm ERR! code EACCES
      npm ERR! syscall access
      npm ERR! path /usr/local/lib/node_modules/expo-cli
      npm ERR! errno -13
      npm ERR! Error: EACCES: permission denied,...

  You have to give root permission ,like for linux:

•   sudo npm install --global expo-cli

Installation

1. Clone the repo

   git clone https://github.com/vivek9patel/CPU-Scheduling-APP-React-Native.git

2. Install Expo packages

   npm install expo

• Now your project folder should look like this :

      └── CPU-Scheduling-APP-React-Native-master
      ├── App.js
      ├── app.json
      ├── assets
      ├── babel.config.js
      ├── models
      ├── node_modules
      ├── package.json
      ├── package-lock.json
      ├── README.md
      ├── routes
      └── screens

Usage

• You can run this project by starting the metro server

  npm start

  or

  expo start

• If you are using expo , you can debug the project by installing expo app on your mobile devices & scanning the QR code.

  • Expo App Android
  • Expo App IOS

• You can also debug the application by running the emulators on your systems.
