Kilua Project Wizard for IntelliJ IDEA

Robert Jaros — Tue, 03 Jun 2025 05:18:33 +0000

I have published a new, free plugin for IntelliJ IDEA - a project wizard for my Kilua framework.

The plugin allows you to easily start new web project with Kilua and Kotlin. You can choose a number of different options:

a project type - frontend or fullstack with one of five different servers, including Ktor, Spring Boot, Javalin, Jooby and Vert.x
web targets - K/JS, K/Wasm or both
a number of optional modules, including Bootstrap and TailwindCSS
whether to generate SSR (Server-Side Rendering) code
whether to generate test sources
internationalization code with gettext plugin and sample *.po translations.

The plugin is open source and written in Kotlin - you can check the sources in the GitHub repository.

This is an initial release, there might be some bugs - any feedback is appreciated!

Kilua - new Kotlin/Wasm web framework

Robert Jaros — Mon, 15 Apr 2024 11:28:06 +0000

I have published Kilua 0.0.1 - the first public release of my new compose powered web framework for Kotlin/Wasm and Kotlin/JS.

Kilua allows you to:

Use powerful Compose programming model and state management to develop web applications.
Compile the same application code for Kotlin/Wasm and Kotlin/JS targets.
Create fullstack applications with companion Kilua RPC library.
Deploy your application with full SSR (Server Side Rendering) for better SEO performance and user experience.

Kilua is similar to compose-html, but it has considerable advantages:

Webassembly support
Server Side Rendering
a lot of ready to use components
fullstack RPC with fullstack UI components
i18n support with gettext
imperative API layer to directly interact with UI components

If you want to see how to write Kilua applications, you can find fully compatible TodoMVC and RealWorld example applications, alongside other demo apps in the examples directory.

More information can be found at https://github.com/rjaros/kilua.

KVision 7.0.0 is released

Robert Jaros — Thu, 17 Aug 2023 12:02:20 +0000

KVision is an open source web framework created for Kotlin/JS. It allows developers to build modern web applications with the Kotlin language.

I have released KVision 7.0.0. This is a major upgrade bringing new features and some breaking changes.

Highlights of this release include:

Upgraded dependencies (Kotlin 1.9.0, Coroutines 1.7.3, Serialization 1.6.0-RC, KSP 1.0.13, Jooby 3.0.2, Spring Boot 3.1.2, Ktor 2.3.3, Micronaut 4.0.3, Koin 3.4.3, kotlin-wrappers 615, Gradle 8.3-rc-3, npm-publish 3.4.1, Bootstrap 5.3.1, Chart.js 4.3.3, Tempus dominus 6.7.11, Electron 25.5.0, Fontawesome 6.4.2, Handlebars 4.7.8, Imask 7.1.3, Tabulator 5.5.1, Tom Select 2.2.5).
Migration from Kotlin JS to Kotlin Multiplatform gradle plugin for both KVision itself and all example and template projects.
Integrated custom gradle tasks with KVision gradle plugin for all fullstack apps, to simplify and unify application build files.
Support Server-Sent Events connections in fullstack applications for all supported backend servers.

For more details about this release see the changelog.

Multiplatform plugin

Since Kotlin 1.9.0 Kotlin("js") Gradle plugin is deprecated and KVision is no longer using it. Only Kotlin("multiplatform") is supported. The migration is quite easy and well documented in the official guide. In general you just need to rename your source sets and source directories.

Fullstack changes

All custom Gradle tasks for fullstack applications are now integrated with KVision Gradle plugin. Also the source sets names are changed to standard jsMain and jvmMain (instead of frontendMain and backendMain). This makes KVision build files way simpler and unified. It's also a lot easier to convert a frontend-only project to a fullstack application.

KVision 7 allows you to use SSE (server-sent events) with all supported backend servers. Just like with KVision websockets connection, the implementation is fully type-safe and is based on Kotlin coroutines channels.

New examples

There are new examples in the repo. The template-fullstack-ktor-koin-annotations project shows you how to use Koin Annotations. And the tweets-fullstack-spring-boot-sse project implements a very simple chat application with server-sent events.

Migration

As with any other major release there are breaking changes in 7.0.0. A dedicated migration guide is available, so be sure to read it before upgrading.

KVision 6.0.0 is released

Robert Jaros — Sat, 31 Dec 2022 10:18:16 +0000

KVision is an open source web framework created for Kotlin/JS. It allows developers to build modern web applications with the Kotlin language.

I have released KVision 6.0.0. This is a major upgrade bringing a lot of significant changes and new features.

Highlights of this release include:

Java 17 or greater is now required.
Upgraded dependencies (Kotlin 1.8.0, Spring Boot 3.0.1, Micronaut 3.8.0, Ktor 2.2.1, Koin 3.3.0, Vert.x 4.3.7, kotlin-wrappers 466, Chart.js 4.1.1, Npm-publish 3.2.0, Bootstrap-icons 1.10.3, OnsenUI 2.12.8, Tempus-dominus 6.2.10, Trix 2.0.4, Electron 22.0.0, Tabulator 5.4.3).
Drop support for the deprecated legacy backend.
Direct dependency on kotlinx.coroutines library.
Support for returning Result<T> from fullstack remote methods.
New Upload component based on browser file input API.
New Numeric and ImaskNumeric components for handling decimal numbers.
New kvision-ballast and kvision-routing-ballast modules integrating with Ballast state management framework.
A lot of other bugfixes, cleanups and optimizations.

For more details about this release see the changelog.

Requirements

Following the path of Spring Boot, which from version 3.0 is targeting Java 17+, KVision also requires the latest LTS release of the JDK. Dropping support for the old, legacy backend is also a natural thing, since it's now deprecated in Kotlin 1.8.0.

As a result, we've simplified the codebase, reduced the resulting bundle sizes, and improved the performance, stability and security of fullstack applications.

Components

A few JavaScript libraries which were used by KVision components lost their support and proper maintenance. We had to remove those components and replace them with some other libraries. Fortunately the rich JS ecosystem provided good alternatives. New TomSelect and TomTypeahead components, based on the lightweight TomSelect library offer similar feature set to the old Select and Typeahead components, although the API is slightly different.

We've also put a lot of work to the numeric components. Instead of one spinner component, we now have three numeric components - Spinner for integer values, Numeric for fixed decimals and ImaskNumeric for decimal/float values with fully masked and configurable input.

Integrations

New modules allow you to easily build KVision apps with the Ballast opinionated application state management framework. You can see how Ballast (together with Koin) can help you design your application architecture in the new todomvc-ballast example.

It's also easier to use coroutines in your projects, because kotlinx.coroutines library is now a direct dependency of all KVision applications (note: you can still develop apps without using coroutines without larger bundle size).

Migration

As with any other major release there are breaking changes in 6.0.0. A dedicated migration guide is available, so be sure to read it before upgrading.

KVision 5.6.0 is released

Robert Jaros — Mon, 29 Nov 2021 16:53:03 +0000

KVision is an open source web framework created for Kotlin/JS. It allows developers to build modern web applications with the Kotlin language.

I have released KVision 5.6.0. Some major dependencies were upgraded, keeping KVision up to date with both Kotlin and JavaScript ecosystem.

Highlights of this release include:

Kotlin 1.6 support
Upgraded dependencies (Coroutines 1.6.0-RC, Serialization 1.3.1, Spring Boot 2.6.0, Ktor 1.6.6, Micronaut 3.2.0, Dokka 1.6.0)
Upgraded Snabbdom, Tabulator and Chart.js libraries
Other bugfixes and improvements

For more details about this release see the changelog.

Both kvision-tabulator and kvision-chart modules are now based on new major versions of Tabulator Tables and Chart.js. Both modules contain breaking changes. Please take a look at the migration guides for Tabulator 5 http://tabulator.info/docs/5.0/upgrade and Chart.js 3 https://www.chartjs.org/docs/latest/getting-started/v3-migration.html. Unfortunately both are quite huge documents. If you still want to use old versions, just change KVision dependencies - the old modules are published with new names: kvision-tabulator4, kvision-tabulator4-remote and kvision-chart2. The old components are deprecated but there are no plans to remove them (at least not before KVision 6).

KVision v4.0.0 is released (major upgrade with lots of improvements)

Robert Jaros — Sun, 14 Feb 2021 18:55:42 +0000

KVision is an open source web framework created for Kotlin/JS. It allows developers to build modern web applications with the Kotlin language.

I have released KVision 4.0.0. This is a major upgrade bringing a lot of significant changes and new features.

After the information about the upcoming sunset of Bintray warmed the Java/Kotlin community, I've made the decision to move publication to Maven Central while changing group identifier and package name to io.kvision at the same time. This is a breaking change for all KVision projects, but a simple global replace should fix the problems. More details can be found in the migration guide.

Other highlights include:

Update to Kotlin 1.4.30 with IR backend enabled by default in all templates and examples.
Upgraded dependencies (Serialization 1.1.0-RC, Ktor 1.5.1, Javalin 3.13.3, Vert.x 4.0.2, Micronaut 2.3.2, Dokka 1.4.20, Gradle 6.8.1, Bootstrap 4.6.0, NPM Publish 1.1.1).
Support bidirectional data binding for all form components.
Support for custom serializers module in the RestClient component.
Major performance optimizations.

Enabling IR by default can now significantly decrease the bundle size of most KVision projects, without much additional trouble.

For more details about this release see the changelog.

I've also published new example demo application, created with Patternfly UI toolkit. It presents how easy it is to create KVision application with a modern design system alternative to Bootstrap, even without direct support for this toolkit. You can find sources in the kvision-examples GitHub repo and live demo here.
Note: The application is heavily inspired by the Patternfly Kotlin project demo.

KVision 3.18.0 is released (with new Progress component and IR backend fixes)

Robert Jaros — Wed, 16 Dec 2020 12:34:52 +0000

KVision is an open source web framework created for Kotlin/JS. It allows developers to build modern web applications with the Kotlin language.

I have released KVision 3.18.0, the first release (and I hope not the last!) where external contributions are the most valuable.

The highlights of this release include:

Upgraded dependencies (Kotlin 1.4.21, Ktor 1.4.3, Spring Boot 2.4.1, Vert.x 4.0.0, Micronaut 2.2.1, Jackson Module Kotlin 2.12.0)
New Progress component
Simple way to use KVision components as React children
Fixes for the IR compiler backend

I would like to thank Yannik Hampe, for his fantastic work on Progress component and all code-base cleanups and refactorings.

I'm also announcing KVision Project Wizard IDEA plugin, which allows to easily create new KVision projects directly from IntelliJ IDEA, with support for all frontend and fullstack project versions. Many thanks to Jakub Neukirch for creating and maintaining the project.

KVision v3.17.0 is released (with IR backend support)

Robert Jaros — Fri, 27 Nov 2020 01:05:57 +0000

KVision is an open source web framework created for Kotlin/JS. It allows developers to build modern web applications with the Kotlin language.

I have released KVision 3.17.0, the first version of the framework supporting new Kotlin/JS IR compiler backend. All artifacts are published in "both" mode, so you can now choose the legacy or the IR compiler for your applications.

All examples, both frontend and fullstack, have been tested and are fully compatible with new backend.

However, note that we are still impatiently waiting for Kotlin 1.4.30, which will fix important bug and make KVision really usable with IR. Until then, the legacy backend is still the one to be used by default.
