Setup Room in Compose

To use Room in your app, add the following dependencies to your app’s build.gradle file:

dependencies {
  def room_version = "2.2.6"

  // FOR ROOM
  implementation "androidx.room:room-runtime:$room_version"
  kapt "androidx.room:room-compiler:$room_version"
  
  // optional - Kotlin Extensions and Coroutines support for Room
  implementation "androidx.room:room-ktx:$room_version"
  // END FOR ROOM
}

Components of Room

There are 3 major components in the Room:

• The database class that holds the database.
• Data entities that represent tables in your app’s database.
• Data access objects (DAOs) provide methods that your app can use to query, update, insert, and delete data in the database.
