themeVersion

Configure the version that will appear in the pom.xml file within the jar file of your theme and in the kcContext.themeVersion.

This is purely indicative, it's a way for you to quickly see what version of your theme is in production.

By default the version that is used is the one in the package.json of your project

package.json

{
  "version": "1.3.4"
}

But you can overwrite this value using an environment variable:

Vite

vite.config.ts

import { defineConfig } from 'vite'
import react from '@vitejs/plugin-react'
import { keycloakify } from "keycloakify/vite-plugin";

export default defineConfig({
  plugins: [
    react(), 
    keycloakify({
      themeVersion: "1.2.3"
    })
  ],
})
