What is Nyxo App

Nyxo is a mobile application for improving your sleep. Its built with React Native, AWS Amplify, styled-components, and Redux. Nyxo provides the following features:

  • Sleep tracking, with support for multiple different trackers
    • Google Fit
    • Apple Health
    • Oura
    • Withings
    • Fitbit
    • Polar
  • Sleep trends and sleep diary
  • Nyxo Cloud: backup your sleep data and coaching progress, and access it from nyxo.app
  • 4 week sleep coaching program
  • Ask experts, if you have any questions we have the professional sleep coaches to help
  • And more

The plan is to develop Nyxo further and allow contributions from everyone. If you want to for example build a new sleep visualization or add support for new sleep tracker, we will gladly welcome a pull request of that :)

Can I help?

Always!

If you know a language other than English, help us translate the app!

Getting started

Start by cloning repository and installing dependencies using yarn

git clone
cd nyxo-app
yarn

Link assets

react-native link

For iOS, install Cocoapods and run command

cd ios && pod install

Setting up the environment and services

App Center Set up Microsoft's Visual Studio App Center for event analytics & crash reports: https://docs.microsoft.com/en-us/appcenter/sdk/getting-started/react-native

Sentry Set up Sentry for React Native by executing the command. More Sentry-related information can be found at: https://docs.sentry.io/platforms/react-native/

AWS-amplify

We use aws-amplify for our api and authentication. We will most likely simplify the process of setting up Amplify in fresh project at some point. At the moment the worfklow for getting everything to run is following:

  • Get AWS account
  • See the instructions for installing amplify-cli
  • Do the following setup

Setting up enviroment variables

Nyxo configurations keys are placed in config.ts file, which then references the requirement enviroment variables from local .envfile. Head to docs/env-structure.md file to learn more. The way the project is structured you should need to provide keys for all the services to make the app work.

After creating the .env file, run yarn rnuc .env to generate variable files.

Troubleshooting

main.jsbundle missing

Run command react-native bundle --entry-file index.js --platform ios --dev=false --bundle-output ios/main.jsbundle --assets-dest ios for iOS Run command react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res/ for Android

When you get a weird Xcode error about undefined symbols

If you see something like this:

Undefined symbols for architecture x86_64: "_OBJC_CLASS_$_RCTReconnectingWebSocket", referenced from: objc-class-ref in libReact.a(RCTPackagerConnection.o) ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

Delete your Derived data

If you run into an Xcode build input file error

If you see a build error like this:

error: Build input file cannot be found: '/...path/Nyxo.app/PlugIns/NyxoTests.xctest/NyxoTests' (in target 'NyxoTests' from project 'Nyxo')

Switch your XCode Build System to Legacy Build System

Resetting bundlers etc.

  1. Clear watchman watches: watchman watch-del-all.
  2. Delete the node_modules folder: rm -rf node_modules && npm install.
  3. Reset Metro Bundler cache: rm -rf /tmp/metro-bundler-cache-* or npm start -- --reset-cache.
  4. Remove haste cache: rm -rf /tmp/haste-map-react-native-packager-*.
