Kotlin .encodeToString()

The encodeToString() function is provided by the Kotlin Serialization library. It is used for serializing data to a string representation (commonly in JSON format).

Syntax

fun <T> encodeToString(serializer: SerializationStrategy<T>, value: T): String

• serializer: An instance of SerializationStrategy that defines how the data should be serialized.
• value: The object or data to be serialized to a string.

Example

Here is an example of how to use encodeToString() to serialize data into a JSON string:

import kotlinx.serialization.Serializable
import kotlinx.serialization.encodeToString
import kotlinx.serialization.json.Json

@Serializable
data class Person(val name: String, val age: Int)

fun main() {
  val person = Person("Johnny", 30)

  // Serialize the data class to a JSON string using encodeToString()
  val jsonString = Json.encodeToString(person)

  println(jsonString)
}
