About Kotlin/JS Inspection Pack
Kotlin/JS Inspection Pack
Deprecation warning
All features of this plugin have been moved into the main IDEA Kotlin plugin, and will be available starting with IDEA 2023.1 (a.k.a IDEA platform 231), and further. These new IDEA versions will not, therefore, suggest installing of this plugin.
You can still download and use the plugin with older IDEA versions.
Plugin description
This plugin adds useful inspections, intentions, and quick-fixes for working with Kotlin/JS projects. It provides helpful functionality when you’re building new applications using Kotlin/JS, and it helps you migrate existing applications to the Kotlin/JS IR compiler.
The following features are available with this plugin:
• Convert JS and React-related classes and interfaces to external interfaces
Using Kotlin interfaces and classes (including data classes) that derive from pure JS classes, such as React's RState and RProps, can cause ClassCastExceptions. This plugin allows you to convert such classes and interfaces to external interfaces.
• Convert properties of external interfaces to var
Properties of external interfaces in Kotlin/JS code can't be read-only (val) properties.
The plugin contains a quick-fix that allows you to convert the read-only properties of an external interface into mutable var properties.
• Make boolean properties nullable in external interfaces
In JavaScript, a boolean variable can be null or undefined. Kotlin requires you to explicitly specify the nullability of boolean variables in external interfaces to prevent ClassCastExceptions.
Now there is an inspection that will highlight boolean properties in external interfaces and offer to make them nullable (Boolean?).
Feedback
If you encounter any issues with the inspections in the plugin, please report them in our issue tracker. For problems with Kotlin/JS, please report them the same way.
