Walkthrough

A tutorial documentation file is updated to replace the previous GET-based endpoint example with a new POST-based example that demonstrates request body validation using Elysia's schema system.

Changes

Cohort / File(s)	Summary
Getting Started Tutorial docs/tutorial/getting-started/validation/index.md	Updated example code: added t to Elysia imports; replaced GET endpoints with a POST /user route; introduced request body validation schema using t.Object({ name: t.String() }) to validate incoming request data; updated handler to read name from request body and return a greeting.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~5 minutes

• Verify the validation schema syntax and semantics are correct
• Confirm the example accurately demonstrates validation best practices
• Check that the code example is clear and follows the tutorial's intended learning objectives

Poem

A rabbit hops through validation's way,
POST requests now save the day!
With schemas tight and strings so true,
The tutorial shows what bodies can do! 🐰✨

131-142: Use spaces instead of hard tabs in code blocks.

The markdown linter flags hard tabs (MD010 violation) in the answer code snippet. Markdown convention is to use spaces for indentation.

Apply this diff to replace hard tabs with spaces:

-import { Elysia, t } from 'elysia'
-
-new Elysia()
-	.post(
-		'/user',
-		({ body: { name } }) => `Hello ${name}!`,
-		{
-			body: t.Object({
-				name: t.String()
-			})
-		}
-	)
-	.listen(3000)
+import { Elysia, t } from 'elysia'
+
+new Elysia()
+  .post(
+    '/user',
+    ({ body: { name } }) => `Hello ${name}!`,
+    {
+      body: t.Object({
+        name: t.String()
+      })
+    }
+  )
+  .listen(3000)

Note: The main example in lines 40–51 also uses hard tabs, so you may want to address the linting issue file-wide for consistency.

131-142: Answer snippet correctly demonstrates request body validation.

The code changes are correct and well-suited for a tutorial answer. The simplification (removing the age field from the schema) appropriately reduces complexity compared to the main example while still illustrating the core concept of validating request body data.
