Error Handling

Define custom error handlers to handle all errors in your app.

Usage

const app = new Kyrin({
  onError: (err, c) => {
    console.error(err);
    return c.json({ error: err.message }, 500);
  }
});

Validation Errors

Works with Zod validation:

import { z } from "zod";

const app = new Kyrin({
  onError: (err, c) => {
    if (err.name === "ZodError") {
      return c.json({ 
        error: "Validation failed", 
        issues: err.issues 
      }, 400);
    }
    return c.json({ error: err.message }, 500);
  }
});

const userSchema = z.object({ name: z.string() });
app.post("/users", userSchema, (c) => {
  const body = c.body();
  return c.json(body);
});

Default Behavior

If you don't define onError:

• Development mode: Shows error details with stack trace
• Production mode: Shows "Internal Server Error" only
