Barcode Scanner

This is a "Hello World!" mobile app to test Expo.io React Native mobile application.

This app will someday scan a UPC barcode and display the product image onscreen. At least, that's the plan. :-) This is a test project, so do not expect this to actually happen.

I used the Expo Snack and installed the app on a old LG Optimus (Verizon prepaid) phone, but I have been looking to take the next steps.

Steps to Setup

Using Linux operating system (OS) Ubuntu 17.10.

Sign up for Expo account. https://expo.io/signup

Install latest nvm scripts. (Node Version Manager, makes swapping Node and NPM versions easier.) https://github.com/creationix/nvm#install-script

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.8/install.sh | bash

Log out and then log back in again for updated profile settings to take effect.

Install Node. (Note, I am got a warning with this Node version later on, but have been able to continue thus far.)

[exp] Warning: You are using npm version 5.6.0. There may be bugs in this version, use it at your own risk. We recommend version 4.6.1.

nvm install 8.9
nvm use 8.9

Then follow the Expo.io step-by-step guide from Step 3. Get the Command Line Tool
