Introduction

Recipe app created to put in practice my learnings of the book Jetpack compose by tutorial - Kodeco

Screenshots

Home & Detail	Map

Requirements

The application must contain the following screens:

• Home Screen: Lists available recipes and a search bar.
• Detail Screen: Displays detailed information about a selected recipe.
• Map Screen: Shows the location of the selected recipe.

Solution

The app makes use of Clean Architecture to separate the application's logic into layers. The presentation layer displays the information to the user, the domain layer manages business logic, and the data layer handles data access.

The MVVM pattern separates the view logic from the application logic. The view presents information to the user, and the application logic provides information to the view.

Flows are used to manage the request of the data outside the main thread

The proposal takes advantage of Compose to build the user interface.

How to run

• Gradle JDK: Java 17 should be used Build > Execution > Deployment > Build tools > Gradle)

Good Practices

The application implements the Android version catalog to ensure compatibility with the latest Android versions.

Gradle KTS is used to write the application's build script.

Automated Tests

The application includes automated tests for verifying the application's logic.

Areas for Improvement

The application could be enhanced in the following areas:

• Abstraction of the HTTP client in ktorClientImpl.
• Addition of an interceptor to detect network status changes before making a request.
• Unit tests for ktorClientImpl.
• Implementation of database persistence.
• Interface segregation in LocalDataSource.
• Improvement of test object creation with a factory method.

Used Libraries

The application utilizes the following libraries:

• ktor for backend communication.
• coil for image loading.
• navigation for screen navigation.
• maps for displaying maps.
• dagger for dependency injection.
• turbine for debugging flows.
• coroutines for asynchronous programming.
• kotest for automated testing.

UX/UI

The UX/UI was inspired by the following design hosted by Figma and all the rights belong to its creator, this app does not have the intention to be published on any Marketplace Store.
