Migration

Check this page when upgrading to a new version of KVision. Any backwards-incompatibilities will be described here. This is an evolving framework and things may change as refactorings and improvements take place, but we aim to keep the core as stable as possible.

Check Migration guide for KVision 7.0.0.

This is the list of incompatibilities you may encounter when migrating your application to KVision 6.4.0:

• Guice was upgraded to 7.0.0 and you need to replace your javax.inject imports with new jakarta.inject namespace when using Guice with Javalin, Jooby, Ktor or Vert.x. See: https://github.com/google/guice/wiki/Guice700#jee-jakarta-transition

• Jooby was upgraded to 3.0.0.M9 (a milestone release). See: https://github.com/jooby-project/jooby/blob/3.x/docs/asciidoc/migration.adoc

This is the list of incompatibilities you may encounter when migrating your application to KVision 4.7.0:

• You need to upgrade Kotlin to 1.5.10.

• Due to changes in webpack-dev-server you need to modify DevServer options in your build.gradle.kts file. Please replace:

  • proxy = mapOf(...) with proxy = mutableMapOf(...)

  • contentBase = listOf(...) with static = mutableListOf(...)

This is the list of incompatibilities you may encounter when migrating your application to KVision 4.5.0:

• You need to upgrade Kotlin to 1.5.0 and serialization to 1.2.0 in your project gradle.properties.

• Webpack used internally by Kotlin/JS plugin was upgraded to 5.x. You need to adjust any custom configuration in your webpack.config.d directory. Please use these bootstrap.js, css.js and file.js files as examples. You can find more information here.

• kvision-onsenui-css module was removed and integrated with kvision-onsenui module.

• When developing full-stack application with Spring Boot 2.4.5, you need to add this snippet to your build.gradle.kts:

extra["kotlin.version"] = "1.5.0"
extra["kotlin-coroutines.version"] = "1.5.0-RC"

This is the list of incompatibilities you may encounter when migrating your application to KVision 4.1.0:

• DSL builder functions have been annotated with @DslMarker annotation, which provides strict scope control over implicit receivers. It can lead to compile errors for existing code with hard to notice bugs. Sometimes it may also be necessary to specify the receivers explicitly.

• Routing functionality has been externalized to optional modules. If your application uses built-in KVision routing, you need to add kvision-routing-navigo module to your dependencies and call Routing.init() at the beginning of your Application.start() method.

This is the list of incompatibilities you may encounter when migrating your application to KVision 4.0.0:

• Artifacts publication has been moved to Maven Central under new maven coordinates with io.kvision group identifier. You have to update all KVision dependencies in your build.gradle.kts.

• All package names have been renamed with io.kvision prefix. You should replace your sources in the following order:

  • pl.treksoft.navigo with io.kvision.navigo

  • pl.treksoft.jquery with io.kvision.jquery

  • pl.treksoft.kvision with io.kvision

• Make sure you are not using any deprecated code before migrating. All methods, classes and functions deprecated before version 4.0.0 have been removed.

• If you use web sockets with Ktor backend you need to manually install WebSockets feature in your main() function.

• If you use Ktor backend you should move kvisionInit() call to the end of your main() function.

• If you use moment module with locale support you need to manually require() all or some of the needed locales. You should also update moment.js file in the webpack.config.d directory from the current template.

• You should remove all Bintray repository addresses from your Gradle build files.

This is the list of incompatibilities you may encounter when migrating your application to KVision 3.13.x:

• Due to changes in the Kotlin/JS gradle plugin for Kotlin 1.4.0 it is necessary to fix your build.gradle.kts file and webpack.config.d/webpack.js file. You can apply the following patch for build.gradle.kts file and just copy new version of webpack.js from the current template project (standard or fullstack, respectively).

kvision-3.13.0.txt

• Kotlinx.serialization library 1.0.0 contains a lot of incompatible changes, so you have to migrate your code if you are using this library directly.

• Jed was replaced by gettext.js library. You can safely delete webpack.config.d/jed.js file. You need to make sure your *.po files contain both Language and Plural forms headers.

• All flexbox and grid CSS properties and enums have been moved to the StyledComponent and the core package. Deprecated type aliases for refactored enums were added. Follow deprecation messages to remove deprecated types from your code.

• If you are using fullstack configuration with Spring Boot add extra["kotlin.version"] = "1.4.0" to your build.gradle.kts file.

This is the list of incompatibilities you may encounter when migrating your application to KVision 3.5.x:

• Due to changes in the Kotlin/JS gradle plugin it is necessary to fix your build.gradle.kts file and webpack.config.d/webpack.js file. Carefully analyze these changes for frontend projects and these changes for fullstack projects.

• Kotlinx.serialization library 0.20.0 contains also some incompatible changes, so you have to migrate your code if you are using this library directly.

This is the list of incompatibilities you may encounter when migrating your application to KVision 3:

• The setEventListener() method and the onEvent() extension function return now an Int instead of a Widget. The returned value can be used with removeEventListener(id: Int) method.

• The old, deprecated setEventListener() method without type parameter has been removed. Use onEvent instead.

• Problematic overloaded constructors for all css styling classes in the core package - Color, Border, Background, TextDecoration and TextShadow has been removed. Each class has only one, primary constructor.

• There are two new factory extension functions for the Color class. Color.hex() allows you to create a Color object from a hexadecimal Int literal. Color.name() allows you to create a Color object with an Col enum value.

• The dependency on the Pac4J library has been removed. The p.t.k.remote.Profile class has been removed as well. You can add Pac4J to your own project if you still want to use it.

• Jooby has been updated to version 2.x. You need to upgrade your application if you are using Jooby integration. See upgrade docs.

This is the list of incompatibilities you may encounter when migrating your application to KVision 2:

• All DSL builder functions have been moved out of the companion objects to allow better auto-completion in IntelliJ IDEA. This change is incompatible with KVision 1 code. To migrate you should just remove code based on this regular expression: [^\.]+\.Companion\. from all your frontend code imports (Kotlin compiler will help you easily find all possible errors afterwards).

• The default font size in Bootstrap 4 is larger. You may have to adjust your application layout manually or use a custom CSS theme.

• The direct child of the Root component is no longer 100% wide. Use width = 100.perc if you want it to be.

• The modules names have changed (the API of the components, package names, class names, methods and properties are mostly the same, with the differences described in details below).

KVision 1 module name	KVision 2+ module name
kvision-select	kvision-bootstrap-select
kvision-select-remote	kvision-bootstrap-select-remote
kvision-datetime	kvision-bootstrap-datetime
kvision-spinner	kvision-bootstrap-spinner
kvision-upload	kvision-bootstrap-upload
kvision-dialog	kvision-bootstrap-dialog

• Two new modules: kvision-bootstrap-css and kvision-fontawesome were extracted from the kvision-bootstrap module.

• The Glyphicons support is dropped. Use Font Awesome icons instead.

• The Font Awesome icon names require a style prefix (fas, far or fab).

• Components like dropdown, context menu, modal, window, progressbar, navbar, toolbar, responsive grid, tab panel, tooltip and popover were moved into kvision-bootstrap module.

• ButtonStyle.DEFAULT was removed. The ButtonStyle.PRIMARY value is the new default. New ButtonStyle.SECONDARY value is also available.

• RadioStyle.DEFAULT and CheckBoxStyle.DEFAULT were removed and are no longer necessary.

• The deprecated Label component was removed. Use Span component instead.

• TableType.CONDENSED was removed. Use new TableType.SMALL value instead.

• ButtonGroupStyle.JUSTIFIED was removed. Use a different approach.

• The responsive property of the Table component was removed. Use responsiveType property with a chosen enum value instead.

• The dropup property of the DropDown component was removed. Use thedirection property with a Direction.DROPUP value instead.

• The withCaret parameter of the DropDown component constructor was removed. No replacement at the moment.

• NavbarType.STATICTOP was removed. Use NavbarType.STICKYTOP instead.

• Do not use Tag(TAG.LI) components when creating links inside Nav component. Use Link with nav-item and nav-link classes (or use navLink DSL builder function).

• When adding links to the DropDown or ContextMenu use Link with a dropdown-item class (or use ddLink and cmLink DSL builder functions respectively).

• GridSize.XS was removed from the ResponsiveGridPanel component.

• The buttonsType is no longer a var property in the Spinner and the SpinnerInput components (changing its value didn't work anyway ;-)

• The DateTime and DateTimeInput components are based on a new version of bootstrap-datetimepicker. The weekstart, todayhighlight andshowmeridian properties were removed. The todayBtn and clearBtn properties were renamed to showTodayButton and showClear respectively.

• The ObservableList class was moved from pl.treksoft.kvision.utils to pl.treksoft.kvision.state package.

• The StateBinding component was moved from pl.treksoft.kvision.redux to pl.treksoft.kvision.state package and is available in the main KVision module. It also can be used with any data source implementing ObservableState interface (e.g. ReduxStore or ObservableList).

• The mapping of date and time classes between the client and the server code was significantly changed. The pl.treksoft.kvision.types.Date class is deprecated and not supported anymore. You should use LocalDateTime, LocalDate, LocalTime, OffsetDateTime and OffsetTime from pl.treksoft.kvision.types package instead. All of these classes are mapped to kotlin.js.Date on the client side, but to the corresponding java.time.* class on the server side. This way you can easily use new Java types in your server side applications.

• The pl.treksoft.kvision.hmr package was removed and is not needed anymore. All KVision applications should now extend pl.treksoft.kvision.Application class and are executed with new startApplication() function.

• ReduxStore.subscribe() method calls the callback function once immediately right after the registration.

• Service functions for SelectRemote / TabulatorRemote were changed to suspending. The function for SelectRemote component takes additional state: String? parameter.

• You are strongly encouraged to migrate your server-side interfaces common and frontend code with the help of the new KVision compiler plugin.
