TemedicaTest

Prerequisite

• NodeJS
• Xcode or Android Emulator

BACKEND - tbackend

The backend was built on NestJS, which uses typescript by default. By using docker-compose, the set up should be easy as long as you have docker.

Use the following commands to run the nest application

• cd tbackend

• docker-compose up

The backend runs on port 4000 and was done in both GraphQL and REST, to access the graphql playground, go to http://localhost:4000/graphql after running it

To access the RESTful apis, go to http://localhost:4000/v1/drugs

NOTE

To run the app without docker, you need to install @nestjs/cli globally, run npm install -g @nestjs/cli you need to install Mysql workbench and mysql and create a schema/db called temedica, run a yarn install and then yarn start:dev

I used mysql because mongodb does not have a proper query builder in nestjs

TEST

• Run yarn test:watch to run controller and service tests
• Run yarn test:e2e to run e2e tests

MOBILE - tmobile

This was done in react-native, you need to have at least an Xcode to run this on macOS

Use the following commands

• cd tmobile

• yarn install

• npx react-native run-ios for iOS and npx react-native run-android for android

IOS TEST (DETOX)

REQUIREMENTS: node, ios simulator, detox Use this article to install the requirements on a mac https://blog.logrocket.com/end-to-end-testing-in-react-native-with-detox/ I only had the time to run test on iOS using detox

• Make sure the buildPath is pointing to ./ios/build/Products/Debug-iphonesimulator/tmobile.app . If it is not, go to Xcode > Workspace Settings > Advanced > Set build path to custom relative to workspace
• Run npx react-native run-ios
• Open new terminal in the project root and run detox test

FRONTEND - tfrontend

This was done in NextJS,

Use the following commands

• cd tfrontend

• yarn install

• yarn dev

And you can access this by going to http://localhost:3000

TEST

I didn't have enough time to write tests on this

I integrated with Apollo client from the frontend but I can also implement with REST and Redux. I also used debounce to limit excessive calls to the backend. All frontend applications are by default pointing to http://localhost:4000/graphql
