DateField in @trackunit/react-form-components now displays, parses, and hints dates using the user's regional locale while continuing to emit canonical YYYY-MM-DD values to consumers.

The AEMP ISO Diagnostic Trouble Codes time-series endpoint now honors the Accept-Language request header when enriching fault codes with descriptions.

When an Accept-Language header is provided, the language is threaded through to the fault interpretation lookup, so the returned CodeDescription is localized to the caller's preferred language (for example, Accept-Language: da-DK,da;q=0.9,en;q=0.8 returns Danish descriptions) — but only if a translation for that language actually exists for the given fault code.

If no translation exists for the requested language — or if the header is omitted — the response falls back to the fault code's default description (typically English). The set of available languages depends on what the OEM provides and varies by manufacturer; common languages include English (en), German (de), French (fr), Italian (it), Spanish (es), Dutch (nl), Polish (pl), and Japanese (ja).

📝 GET: /15143/-3/Fleet/Equipment/ID/{oemISOIdentifier}/Faults/{startDate}/{endDate}/{pageNumber}

Get diagnostic trouble codes time-series, with fault descriptions localized via the Accept-Language header.

useModal in @trackunit/react-modal has been updated with sheet mode support and container scoping. Modals can now automatically adapt to a sheet presentation when rendered inside a narrow container.

SwipeableDrawer, DrawerPuller, and useSwipeHandlers have been removed from @trackunit/react-drawer. The react-swipeable peer dependency is also gone.

A new Sheet component is now available in @trackunit/react-components. It provides a bottom-sheet UI with snap points, gesture support, and container-scoped rendering — suitable for mobile and responsive layouts.

The WidgetKPI component now supports an onClick prop, making KPI cards interactive with a hover effect, chevron indicator, and keyboard accessibility.

Breaking Change​

WidgetContent padding has changed for KPI widgets using the onClick prop. If your widget previously used padding="responsive", you should update it to padding="none" — the WidgetKPI component now handles its own padding internally.

Iris Apps have been migrated from Rspack to Vite as the build system. Vite provides near-instant dev server startup, fast HMR using native ES modules, and optimized production builds.

Affected packages:

• @trackunit/iris-app-sdk-vite — new package, replaces @trackunit/iris-app-sdk-rspack for build and serve
• @trackunit/iris-app-sdk-rspack — deprecated for Iris Apps, will be removed in a future version

Old executors removed:

• @trackunit/iris-app:build — removed (was already deprecated)
• @trackunit/iris-app:serve — removed (was already deprecated)

Step 1: Update all Trackunit dependencies​

Make sure you are on the latest Trackunit dependencies:

npx npm-check-updates "/@trackunit/" -u

Then install:

npm install
npm install @trackunit/iris-app-sdk-vite -D

Step 2: Update project.json​

Replace the Rspack executors with the Vite equivalents.

Before:

{
  "targets": {
    "build": {
      "executor": "@trackunit/iris-app-sdk-rspack:build",
      "options": {
        "rspackConfig": "apps/{app-name}/rspack.config.ts",
        "outputPath": "dist/apps/{app-name}"
      },
      "outputs": ["{options.outputPath}"]
    },
    "serve": {
      "executor": "@trackunit/iris-app-sdk-rspack:serve",
      "options": {
        "rspackConfig": "apps/{app-name}/rspack.config.ts"
      }
    }
  }
}

After:

{
  "targets": {
    "build": {
      "executor": "@trackunit/iris-app-sdk-vite:build",
      "options": {
        "outputPath": "dist/apps/{app-name}"
      },
      "outputs": ["{options.outputPath}"]
    },
    "serve": {
      "executor": "@trackunit/iris-app-sdk-vite:serve",
      "options": {}
    }
  }
}

Key changes:

• Executor changed from @trackunit/iris-app-sdk-rspack to @trackunit/iris-app-sdk-vite
• The rspackConfig option is removed — Vite works with zero config by default
• Optionally, you can add a viteConfig option if you need custom configuration (see Step 3)

Step 3: Replace rspack.config.ts with vite.config.ts​

Delete your existing rspack.config.ts file.

If you had no customizations in your rspack config (i.e., it just returned the default configuration), you can skip creating a vite config entirely — it works out of the box.

If you need custom configuration, create a vite.config.ts in your app root:

import { defineConfig, UserConfig } from "vite";

export default defineConfig(async (configuration: UserConfig): Promise<UserConfig> => {
    return configuration;
});

You can extend the default configuration by spreading and adding your overrides:

import { defineConfig, UserConfig } from "vite";

export default defineConfig(async (configuration: UserConfig): Promise<UserConfig> => {
    return {
        ...configuration,
        define: {
            ...configuration.define,
            __MY_CUSTOM_FLAG__: JSON.stringify(true),
        },
    };
});

Then reference it in your project.json:

{
  "serve": {
    "executor": "@trackunit/iris-app-sdk-vite:serve",
    "options": {
      "viteConfig": "apps/{app-name}/vite.config.ts"
    }
  },
  "build": {
    "executor": "@trackunit/iris-app-sdk-vite:build",
    "options": {
      "viteConfig": "apps/{app-name}/vite.config.ts",
      "outputPath": "dist/apps/{app-name}"
    }
  }
}

Step 4: Remove tailwind.config.js (if present)​

If your app has a tailwind.config.js file, delete it. Tailwind CSS v4 is now configured automatically by the Vite plugin using PostCSS — no manual Tailwind config is needed.

See the Tailwind 4 upgrade changelog for more details on the Tailwind migration.

Step 5: Clean up old dependencies​

Remove unwanted packages from your NX's package.json (if present):

• @trackunit/iris-app-webpack-plugin
• @trackunit/iris-app-sdk-rspack
• @rspack/core
• @rspack/dev-server,
• copy-webpack-plugin
• css-loader
• esbuild-loader
• style-loader
• postcss
• postcss-loader
• json-loader
• webpack
• webpack-cli
• webpack-dev-server

Then install to update your lockfile:

npm install

Step 6: Verify​

Run serve and build to verify everything works:

# Start dev server
npx nx run {app-name}:serve

# Production build
npx nx run {app-name}:build

The dev server will start on a port in the range 22220–22229 and print a link to open your app:

✨ Iris App is now started, check it out ✨
https://new.manager.trackunit.com/goto/iris-app-dev

New executor options​

Serve options​

Build options​

Bundle analysis​

To analyze your bundle size, set the BUNDLE_ANALYSE environment variable:

BUNDLE_ANALYSE=true npx nx run {app-name}:build

This generates a stats.html file in the output directory using rollup-plugin-visualizer.

Troubleshooting​

CORS errors during development​

The Vite dev server automatically sets CORS headers for Trackunit domains. If you see CORS errors:

1. Verify the Vite server is running
2. Check that "Use Local Apps" is enabled in developer settings
3. Ensure no proxy is interfering with requests

In this version of our Iris App SDK, we have upgraded NX to v22.4.4. Make sure to upgrade your extensions to the latest version of NX.

npx nx migrate 22.4.4
npx nx migrate --run-migrations

Please refer to Maintaining Your Application for more information.

In this version we upgraded the foundation for our tailwind to use tailwind 4.1.18 instead of 3.x.

Effected packages:

• @trackunit/css-core - contains the generated css file to use
• @trackunit/css-tailwind - deprecated, just remove it from your package.json
• @trackunit/css-tailwind-custom-properties-plugin - deprecated, just remove it from your package.json

Also, many of the React libraries have changed, so make sure to update all Trackunit dependencies.

Use this command to make sure you are updated with all latest Trackunit dependencies

npx npm-check-updates "/@trackunit/" -u

Now you need to install the latest tailwind dependencies

npm install @tailwind/postcss@4.1.18 --save-dev
npm install tailwindcss@4.1.18 --save-dev

After this the 'serve' command will use the correct tailwindcss/postcss and all Trackunit dependencies are updated.
