How to convert from Laravel to Kotlin

As technology evolves, developers often find themselves needing to transition between frameworks and languages to best suit their project's needs. Moving from Laravel, a popular PHP framework, to Kotlin, a powerful, statically-typed language running on JVM, is one such scenario. This guide will provide you with a comprehensive overview of this transformation process.

Understanding the Fundamentals

Laravel vs. Kotlin

Before diving into the conversion process, it's essential to understand the core differences between Laravel and Kotlin.

  • Laravel is a robust PHP framework known for its simplicity, elegance, and expressive syntax. It is widely used for crafting web applications and follows the MVC (Model-View-Controller) architectural pattern.

  • Kotlin is a statically-typed programming language designed to interoperate with Java and fully compatible with JVM. It is known for its concise syntax and safety features. Kotlin can be used for back-end development, Android development, and more.

Setting Up Your Kotlin Environment

To begin the conversion from Laravel to Kotlin, you must set up a Kotlin development environment. Install the latest version of the Java Development Kit (JDK) and IntelliJ IDEA, an integrated development environment (IDE) that supports Kotlin.

Initial Project Setup

  1. Create a New Kotlin Project:

    • Open IntelliJ IDEA.
    • Select "New Project."
    • Choose "Kotlin" from the list of templates and follow the prompts to set up your project.
  2. Set Up Gradle or Maven:

    • Kotlin projects typically use Gradle or Maven for dependency management. Selecting one during setup, add necessary dependencies such as Ktor for web development.

Converting Laravel Models to Kotlin Entities

Models in Laravel are used to represent data and interact with the database. In Kotlin, you’ll use data classes along with ORM libraries like Exposed or Hibernate.

Example: Laravel Model to Kotlin Entity

// Laravel User Model
class User extends Model {
    protected $fillable = ['name', 'email', 'password'];
// Kotlin User Entity using Exposed

object Users : Table() {
    val id = integer("id").autoIncrement().primaryKey()
    val name = varchar("name", 255)
    val email = varchar("email", 255)
    val password = varchar("password", 255)

Converting Laravel Controllers to Kotlin

Controllers in Laravel handle HTTP requests and return responses. In Kotlin, you can harness the power of Ktor to handle such tasks.

Example: Laravel Controller to Ktor Route

// Laravel Controller
class UserController extends Controller {
    public function index() {
        $users = User::all();
        return response()->json($users);
// Ktor Route
import io.ktor.application.*
import io.ktor.response.*
import io.ktor.routing.*

fun Route.userRoutes() {
    route("/users") {
        get {
            val users = transaction {
                Users.selectAll().map { 
                    User(it[], it[], it[], it[Users.password]) 

Converting Middleware and Provider Logic

Laravel's middleware and providers serve as filters and service handlers respectively. Ktor offers similar features through interceptors and custom plugins.

Example: Laravel Middleware to Ktor Interceptor

// Laravel Middleware
class CheckAge {
    public function handle($request, Closure $next) {
        if ($request->age < 18) {
            return redirect('home');
        return $next($request);
// Ktor Interceptor
import io.ktor.application.*
import io.ktor.response.*
import io.ktor.routing.*

fun Application.checkAge() {
    intercept(ApplicationCallPipeline.Call) {
        val age = call.request.queryParameters["age"]?.toIntOrNull() ?: 0
        if (age < 18) {
            return@intercept finish()

Converting Blade Templates to Thymeleaf or React

Laravel uses Blade for templating. In Kotlin, options like Thymeleaf or modern front-end frameworks such as React can be utilized.

Example: Blade to Thymeleaf

<!-- Laravel Blade Template -->
<!DOCTYPE html>
<head><title>User List</title></head>
@foreach ($users as $user)
    <p>{{ $user->name }}</p>
<!-- Thymeleaf Template -->
<!DOCTYPE html>
<head><title>User List</title></head>
        <li th:each="user : ${users}" th:text="${}"></li>


Converting from Laravel to Kotlin involves a series of structured steps encompassing environment setup, data modeling, controller logic, middleware, and templating. By understanding the parallels and differences in both technologies, you can approach the migration systematically, ensuring a seamless transition. Adopting Kotlin can provide enhanced performance, scalability, and maintainability for your applications, making the conversion effort worthwhile.
