Mobile app CI/CD demo app built with ReactNative and TypeScript

Monorepo for services and apps related to the RNTDemoApp

Get Started

Install missing prerequisites if neccessary

1. Install Node.js and Yarn
2. Install XCode from the AppStore (for iOS)
3. Install the required tools for running the mobile app locally

Running locally

1. Install dependencies

yarn

2. Start the background worker service (NodeJS app)

(cd services/background-worker && yarn run dev)

Let it fetch and store some data before starting the API

3. Start the backend service (GraphQL API)

(cd services/api && yarn run dev)

4. Start the React Native process and iOS and/or Android simulator in separate terminals as instructed here

Running from Docker Compose

1. Build containers and spin them up

env BUILD_VERSION=$(git rev-parse --short HEAD) docker-compose up --build

2. Ramp down

docker-compose down --remove-orphans

Known issues

MacOS M1

• Building with Docker Compose: disable buildkit

Android simulator

• The API_URL configured in clients/mobile-app/RNTDemoApp/.env needs to point to your local IP address like 192.168.x.x when testing through Docker Compose, with localhost the app fails to connect to the GraphQL endpoint

CI/CD

There's a single Github Action that both builds the Docker images (through Docker Compose) and then deploys the services to Azure Container Apps Environment. The docker-compose.build.yml is reserved for the CI process.
