Kotlinova architecture demo

Playground / demo app for using Kotlinova architecture. It is simple app that loads data from https://dummyjson.com. Features include:

• 100% Compose (single activity)
• Deep links to every screen
• Configuration change and process deaths handling
• Dark mode support
• Material You support
• Improved support for large screens (two-pane layout for user and post list)
• Offline support (data is saved to database and can be browsed offline)
• Pagination
• List of all reusable Compose components in-app (via Showkase)
• Unit tests for UI and all logic code
• Integration tests that test the whole app, optimized with R8
• Easy to use screenshot tests
• Macrobenchmark

See also other branches:

• empty_kotlinova_project = Empty template project with most of the kotlinova architecture set up
• empty_project = Barebones empty project with some essentials pre-created

Readme for the application

Checking out project

1. Install Git LFS
2. Checkout the repo
3. Run git lfs fetch in the repo

Updating versions

Process for updating all library versions::

1. Run ./gradlew dependencyUpdates :buildSrc:dependencyUpdates --no-configuration-cache > /dev/null && ./gradlew :app:updateLibsToml. This will check for new versions of all libraries and automatically bump versions inside libs.toml. Until AGP issue is resolved, auto update is broken. You must open libs.toml, and manually update all versions that are marked in yellow (Lint warning)
2. Check the output of the above task and manually update any libraries that task said it couldn't update automatically.
3. Update Gradle version (see instructions in the gradle wrapper's properties)
4. Sync the project, build the app and run all tests to make sure everything still works.
5. Run detektDebug gradle task to find any new deprecated code
6. For any new deprecated code found by the search:
   • If the fix is trivial, fix it immediately as part of the update commit
   • Otherwise, make a tech debt ticket and add a @Suppress with the ticket number (and/or discuss with the team how to address it)

Creating a new module

1. Right click on the root in the project window, select New and then the project type you want
2. Add module to settings.gradle.kts
3. Add module to app's build.gradle.kts as implementation(projects.newModule))

Hierarchy of the feature modules

Every feature should contain following modules:

• feature-name
  • data - data module with all non-UI logic (such as repositories). No other module (except for top level app) should depend on this.
  • api - interfaces and data models exposed to other modules. This module should generally contain no logic to speed up builds.
  • ui - Module containing feature's ui (Screens / Fragments / ViewModels)
  • test (optional) - Module containing test helpers for all other modules in this group

Running integration tests

./gradlew :app:connectedAndroidTest -PtestAppWithProguard

Creating screenshot tests

To create screenshot tests for your compose screen:

1. Make preview functions public
2. Add showkase plugin to the module of the screen you want to test
3. Add @ShowkaseComposable(group = "Test") annotation to the preview of the screen you want to test
4. run recordPaparazziDebug gradle task to record golden screenshot (double check that only previews for your screen were generated)
