Generic SIP server infrastructure is required. For a working preconfigured example based on OpenSIPS follow:
Edit app/config.js with your server end-points.

Follow the Getting Started guide as much as you can but not everything will be explained. No install docs will be listed here for each tool as they'll change, go and check them out yourself.
Yarn can be a bit of a pain, especially when a git dependency changes.
To be sure you're running the lastest code run:
rm -rf node_modules
rm -r android/app/build
yarn cache clean
yarn
rm -rf ios/Pods
rm Podfile.lock
rm -r ~/.cocoapods
cd ios; pod setup; pod install; cd ..You might want to bring the project back to a clean repo if you're hitting any issues.
Try it as a dry-run first
git clean -d -x --dry-rungit clean -d -x -fnpm rebuild node-sass
Use react-native run-ios --help and react-native run-android --help to give you all you need to know. You shouldn't ever have to build from Xcode or Android Studio.
open ios/sylk.xcworkspace/If you don't have any simulators running, and don't have an android device plugged in (or available to adb) React Native will start up a simulator for you. If you have a device available (doesn't matter if its real or a simulator) this command will output to the device.
yarn react-native run-androidTo see the logs of the attached Android device:
adb logcat '*:W'.
Install https://reactnative.dev/docs/debugging#react-developer-tools
Shake the device and touch Debug.
In XCode enable debugger:
Product -> Scheme -> Edit -> Run -> Build Configuration -> Debug
Start Metro:
npx react-native start
Find the list of connected devices:
xcrun xctrace list devicesGet the id of the device and run:
xcodebuild -workspace ios/sylk.xcworkspace -scheme sylk \
-configuration Debug \
-destination 'id=00008120-0018510402A2201E' \
build installOr press Run inside the sylk target in Xcode.
yarn react-native run-android --deviceId "DeviceId"--deviceId [string] builds your app and starts it on a specific device/simulator with the given device id (listed by running "adb devices" on the command line).
To run the app on your device without tethering it to USB:
On Android:
yarn react-native run-android --mode=release
On iOS:
Select menu Product -> Scheme -> Edit scheme andselect for Run Build Configuration = Release
Beware that iOS push tokens are still meant for sandbox unless the app is released through Apple Store.
We use fastlane for building production versions of the app.
Fastlane can handle all the metadata around your entry into the relevant App Stores and much much more too.
Currently we have two commands - you will need to open Xcode and allow it to sync the deployment key as we allow Xcode to control that rather than do it ourselves. We could add it directly into the project with git-crypt and tell fastlane to use it to make this easier.
fastlane ios betafastlane android betaWe utilise the patch-package module in order to patch the react-native-callkeep module instead of maintaining a complete fork. See their README on how to make changes to the patch and how those patches get installed automatically within this project on install of npm modules.
