ns-demo

Cryptocurrency market difference demo app

This demo is an app that updates the price difference information of the cryptocurrency market (BTC/USD), this app will get realtime prices data from multiple cryptocurrency trading platforms (exchanges) through their websocket server and then display in a mobile list view for users to compare..

• Cryptocurrency exchanges: Bybit, Deribit, Bitmex, Okex, Liquid, Bitmax

NOTE: Because NativeScript PREVIEW (Playground) cannot support Websockets so we must either do a cloud build or a local build; Preview cannot use native "compiled" modules of which NS-Websocket is one of them... In this demo, i used local build on XCode simulator.

Demo:

Run:

Because we must do local build to make this demo work, so we must install full nativescript system requirements first. After that, just run this demo on simulator or connected device:

• Install Nativescript cli:

npm install -g nativescript

• Install dependencies:

tns install

npm install

• Run app in simulator (through tns cli):

tns run ios

# or

tns run android

• If tns cli can't open simulator, we must manual open simulator first and then use tns run again, for ios:

xcrun simctl list
# get udid of the device you want to launch
# Paste this in the terminal
open -a Simulator --args -CurrentDeviceUDID <DeviceUDID>

# run
tns run ios

NOTE:

• If you use XCode 10, we prefer using iOS 10 when running iphone simulator (iOS 12-13 too laggy when running with XCode 10)

TODO:

• Unit test.
• End to End test.
• Try cloud build.
