+
+# How to Validate Multilingual Error Messages in JavaScript Using Robust Validator
+
+## Intro
+
+If you are building an app that supports more than one language, you probably want to show error messages in the right language too. This is called internationalization or i18n.
+
+The good news is that [Robust Validator](https://validator.axe-api.com) makes this very easy. You can switch languages, use custom messages, and even create your own message formats.
+
+In this post, you will learn how to change the language of error messages and set your own custom messages.
+
+## Step 1: Set the Language
+
+By default, Robust Validator shows messages in English. You can switch the language using the `setLocale` function.
+
+```ts
+import { setLocale } from "robust-validator";
+
+setLocale("fr"); // Use French messages
+```
+
+That’s it. All error messages will now be shown in French.
+
+## Step 2: Validate Some Data
+
+Let’s try a simple example with a required rule.
+
+```ts
+import { validate } from "robust-validator";
+
+const data = {
+  name: "",
+};
+
+const schema = {
+  name: "required",
+};
+
+const result = await validate(data, schema);
+
+console.log(result);
+```
+
+If the name field is empty, you will get this message in French (after setting the locale):
+
+```json
+{
+  "isValid": false,
+  "isInvalid": true,
+  "fields": {
+    "name": false
+  },
+  "errors": {
+    "name": [
+      {
+        "rule": "required",
+        "message": "Le champ est obligatoire."
+      }
+    ]
+  }
+}
+```
+
+## Step 3: Add Your Own Messages
+
+You can override the active language by users' selection for every data validation.
+
+```ts
+import { validate } from "robust-validator";
+
+const data = {
+  name: "",
+};
+
+const schema = {
+  name: "required",
+};
+
+const result = await validate(data, schema, { language: "de" });
+console.log(result);
+```
+
+Now when the validation fails, it will return:
+
+```json
+{
+  "isValid": false,
+  "isInvalid": true,
+  "fields": {
+    "name": false
+  },
+  "errors": {
+    "name": [
+      {
+        "rule": "required",
+        "message": "Das Feld ist erforderlich."
+      }
+    ]
+  }
+}
+```
+
+## When to Use This
+
+Multilingual validation is useful when:
+
+- You are building an app for users in different countries
+- You want to make your forms more friendly and clear
+- You are working on international e-commerce, education, or health platforms
+- You just want better control over your messages
+
+## Wrap-Up
+
+Robust Validator makes it easy to show error messages in any language.
+
+This gives you full control over how your validation behaves in a multilingual app.
+
+Try it out today and give your users a better experience in their own language.
