🧠 Core API

Node.js / TypeScript

import { validatePlate } from "@codecorn/euro-plate-validator";

// Italy (car)
validatePlate("AB 123 CD", ["IT"], { vehicleType: "car" });
// → { isValid: true, matches: [{country:"IT", name:"Italy"}], checked:["IT"] }

// UK vs IE
validatePlate("AB12 CDE", ["UK", "IE"]);

🧩 Browser Client SDK — `createEuroPlate()`

The browser client auto-generates a full UI (flag + input + dropdown + status) or attaches to an existing <input>. ecco la versione EN tradotta 1 : 1 . Ho lasciato il codice invariato , e ho applicato lo spazio prima / dopo la punteggiatura solo al testo in prosa .

🧠 Core API ( Node / TS )

import { validatePlate } from "@codecorn/euro-plate-validator";

// IT (car)
validatePlate("AB 123 CD", ["IT"], { vehicleType: "car" });
// → { isValid: true, matches:[{country:"IT", name:"Italy"}], checked:["IT"] }

// UK vs IE
validatePlate("AB12 CDE", ["UK", "IE"]);

🧩 Client SDK ( UI ) — `createEuroPlate`

The client either generates the markup ( flag + input + country dropdown + status ) or attaches to an existing input .

Main options ( including new ones )

type EuroPlateOptions = {
  // DOM
  input?: HTMLInputElement; // external input
  wrapper?: string | HTMLElement | false; // if provided → auto-build UI
  inputId?: string; // default: derived ( e.g., "epv-xxxx-plate" )
  inputName?: string; // default: same
  preserveInputAttrs?: boolean; // NEW: if true, does NOT overwrite existing id/name
  autoFocusOnInit?: boolean; // NEW: default false ( no focus on init )

  // ⚙️ UI configuration ( new: EVERYTHING under "ui" )
  ui?: {
    /**
     * Where to show the status :
     * - "block"  → uses <div class="status"> under the input ( back-compat , default )
     * - "inline" → overlays inside the input , does not change height
     * - "off"    → hides status text / icon
     */
    statusMode?: "block" | "inline" | "off"; // default: "block"

    /** Icon type for inline status ( ignored in "block" and "off" ) */
    statusIcon?: "none" | "icon" | "pill"; // default: "none"

    /** Whether to show status text */
    showStatusText?: boolean; // default: block→true , inline→false

    /** Inline icon position */
    iconPosition?: "right" | "left"; // default: "right"

    // Optional references to existing nodes ( when NOT using wrapper )
    flagIcon?: HTMLElement;
    flagLabel?: HTMLElement;
    dropdown?: HTMLElement;
    button?: HTMLElement;
    status?: HTMLElement;
  };

  // UX / i18n
  mode?: "AUTO" | string; // fixed country or AUTO ( default )
  i18n?: "AUTO" | "IT" | "EN"; // default AUTO → navigator it / en
  allowedCountries?: string[]; // whitelist ; default : all
  vehicleType?: "any" | "car" | "bike"; // default : any
  placeholders?: { auto?: string }; // placeholder for AUTO

  // Normalization / formatting
  normalize?: (code: string) => string; // default GB→UK
  formatters?: Record<string, (s: string) => string>; // per country code

  // Timings
  timings?: { debounce?: number; clear?: number };

  // Dependencies / logging
  deps?: { inputmask?: any }; // manual inject ( e.g., window.Inputmask )
  autoLoadDeps?: { inputmask?: boolean }; // default : true ( autoload UMD )
  cdn?: { inputmask?: string }; // override Inputmask CDN URL
  logger?: Logger;
  debug?: boolean;
};

Values and defaults ( UI )

Key	Type	Values	Default	Notes
`ui.statusMode`	`"block" \| "inline" \| "off"`	block / inline / off	`"block"`	block uses `<div class="status">` , inline overlays inside the input , off hides UI
`ui.statusIcon`	`"none" \| "icon" \| "pill"`	none / icon / pill	`"none"`	used only when `statusMode` is `inline`
`ui.showStatusText`	`boolean`	true / false	`block→true` , `inline→false`	short text in inline ; full text in block
`ui.iconPosition`	`"right" \| "left"`	right / left	`"right"`	icon position for inline
`ui.status`	`HTMLElement` ( optional )	—	auto created / derived	existing host for status when you do not use `wrapper`
`ui.button` / `dropdown` / `flagIcon` / `flagLabel`	`HTMLElement` ( optional )	—	auto created if `wrapper`	for re-using external DOM

Instance methods

type EuroPlateInstance = {
  setCountry(code: "AUTO" | string): void; // alias of setMode
  setMode(m: "AUTO" | string): void; // set fixed country or AUTO
  setAllowed(codes: string[]): void; // dynamic whitelist
  setVehicleType(t: "any" | "car" | "bike"): void;
  setI18n(code: "AUTO" | "IT" | "EN"): void;
  setDebug(on: boolean): void;

  validate(): { ok: boolean; country?: string; value: string };
  destroy(): void;
  getI18n(): "it" | "en";
};

🖼️ Usage examples

A ) Quick start with a shared `common` config + autoload deps ( Inputmask , jQuery , Toastr )

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@codecorn/euro-plate-validator@1.0.14/dist/assets/css/styles.css" />

<div id="plateBox"></div>

<script type="module">
  import * as EuroMod from "https://cdn.jsdelivr.net/npm/@codecorn/euro-plate-validator@1.0.14/dist/browser/index.esm.js";
  import { createEuroPlate } from "https://cdn.jsdelivr.net/npm/@codecorn/euro-plate-validator@1.0.14/dist/client/index.mjs";

  // Common options used across examples
  const common = {
    mode: "AUTO",
    i18n: "IT",
    allowedCountries: ["IT", "FR", "DE", "ES"],
    vehicleType: "any",
    autoFocusOnInit: false,
    ui: {
      statusMode: "inline",
      statusIcon: "icon",
      showStatusText: true, // | false
      iconPosition: "right",
    },
    // Autoload deps (UMD) from CDN
    autoLoadDeps: { inputmask: true, jquery: true, toastr: true },

    // Optional : route logs to Toastr if available
    useToastrLogger: true,

    debug: true,
  };

  createEuroPlate(EuroMod, {
    wrapper: "#plateBox", // optional
    ...common,
  });
</script>

Notes :

With autoLoadDeps.jquery: true and autoLoadDeps.toastr: true the client will fetch UMD builds from CDN when missing .

useToastrLogger: true sends SDK logs and validation notices to Toastr if it is present ( either auto-loaded or injected ) .

jQuery is not required by the core validator ; it is only pulled if your page / widgets rely on it .

B ) You provide `Inputmask` manually ( UMD → `window.Inputmask` )

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@codecorn/euro-plate-validator@1.0.14/dist/assets/css/styles.css" />
<script src="https://cdn.jsdelivr.net/npm/inputmask@5.0.9/dist/inputmask.min.js"></script>

<script type="module">
  import * as EuroMod from "https://cdn.jsdelivr.net/npm/@codecorn/euro-plate-validator@1.0.14/dist/browser/index.esm.js";
  import { createEuroPlate } from "https://cdn.jsdelivr.net/npm/@codecorn/euro-plate-validator@1.0.14/dist/client/index.mjs";

  createEuroPlate(EuroMod, {
    wrapper: "#plateBox",
    i18n: "AUTO",
    autoFocusOnInit: false,
    deps: { inputmask: window.Inputmask }, // manual inject
  });
</script>

C ) Autoload deps from CDN ( default , Inputmask only )

<script type="module">
  import * as EuroMod from "https://cdn.jsdelivr.net/npm/@codecorn/euro-plate-validator@1.0.14/dist/browser/index.esm.js";
  import { createEuroPlate } from "https://cdn.jsdelivr.net/npm/@codecorn/euro-plate-validator@1.0.14/dist/client/index.mjs";

  createEuroPlate(EuroMod, {
    wrapper: "#plateBox",
    i18n: "AUTO",
    autoFocusOnInit: false,
    // No deps object → will autoload Inputmask UMD from jsDelivr
  });
</script>

D ) Autoload ON with a custom CDN URL

createEuroPlate(EuroMod, {
  wrapper: "#plateBox",
  cdn: { inputmask: "https://unpkg.com/inputmask@5.0.9/dist/inputmask.min.js" },
});

E ) Disable autoload ( “no mask” fallback , no error )

createEuroPlate(EuroMod, {
  wrapper: "#plateBox",
  autoLoadDeps: { inputmask: false },
});

F ) Attach to an existing input ( no auto-build )

<input id="myPlate" />
<script type="module">
  import * as EuroMod from ".../index.esm.js";
  import { createEuroPlate } from ".../index.mjs";

  createEuroPlate(EuroMod, {
    input: document.getElementById("myPlate"),
    inputName: "plate_number",
    preserveInputAttrs: true, // do NOT overwrite existing id/name
    i18n: "EN",
    mode: "AUTO",
    autoFocusOnInit: false,
  });
</script>

🧩 WordPress ( WP ) / Elementor

1 ) Enqueue CSS + init helper ( type = "module" )

add_action('wp_enqueue_scripts', function () {
  wp_register_script('epv-init', '', [], null, true);

  wp_enqueue_style(
    'epv-styles',
    'https://cdn.jsdelivr.net/npm/@codecorn/euro-plate-validator@1.0.14/dist/assets/css/styles.css',
    [],
    '1.0.14'
  );

  add_filter('script_loader_tag', function ($tag, $handle) {
    if ($handle === 'epv-init') {
      return '<script type="module">' .
        'import * as EuroMod from "https://cdn.jsdelivr.net/npm/@codecorn/euro-plate-validator@1.0.14/dist/browser/index.esm.js";' .
        'import { createEuroPlate } from "https://cdn.jsdelivr.net/npm/@codecorn/euro-plate-validator@1.0.14/dist/client/index.mjs";' .
        'window.__epvInit=(id,opts)=>createEuroPlate(EuroMod,Object.assign({wrapper:"#"+id,mode:"AUTO",i18n:"IT",debug:true,autoFocusOnInit:false},opts||{}));' .
      '</script>';
    }
    return $tag;
  }, 10, 2);

  wp_enqueue_script('epv-init');
});

⚙️ WordPress / Elementor integration

You can enqueue the CSS and auto-inject a window.__epvInit bootstrapper.

Then, create a shortcode to instantiate it dynamically inside Elementor.

Full example available in the Italian README → “WordPress (WP) / Elementor” section.

- Finalized placeholders via finalizeInputMaskLayouts + scripts/test-placeholders.mjs.
Client SDK
- Centralized logging (imLog, imPreLog, imMounted, imError) using BADGE/LOG when debug: true.
- Lowercase input supported across layouts with L token.
- Examples updated with autoLoadDeps: { inputmask: true, jquery: true, toastr: true } and useToastrLogger: true.
Docs
- CDN bumped to 1.0.14.
