This is important to ensure that your application is secure and that you are not vulnerable to attacks such as SQL injection or cross-site scripting. Additionally, validating your data can help you catch errors early on and prevent them from causing issues later on in your application. Luckily, h3 provides a simple and powerful way to validate data in your Nuxt server routes. h3 is the H(TTP) server framework which is used by Nitro , which is the server engine used in Nuxt 3+. It provides the following utility methods to help you validate your data: getValidatedQuery to validate query parameters getValidatedRouterParams to validate route parameters readValidatedBody to validate the request body h3 allows you to use the validation library of your choice like Zod , Yup , or Joi to validate your data. For this example, we will use Zod to validate the data in our Nuxt server routes with the following schema: 1 import { z } from ' zod ' ; 2 3 const productSchema = z . object ({ 4 name : z . string (). min ( 3 ). max ( 20 ), 5 id : z . number ({ coerce : true }). positive (). int (), 6 }); Let's see how we can use these validation utils to validate query parameters in our Nuxt server routes. Therefore, you can use the getValidatedQuery method provided by h3 instead of getQuery . This method takes the schema that you want to validate the query parameters against and returns the validated query parameters: 1 export default defineEventHandler ( async ( event ) => { 2 const query = await getValidatedQuery ( event , productSchema . parse ); 3 4 return { 5 query , 6 }; 7 }); If you send a valid query like /?name=Product&id=1 , you will get the following response: 1 { 2 " query " : { 3 " name " : " Product " , 4 " id " : 1 5 } 6 } If you send an invalid request that does not match the schema, h3 will throw a 400 Validation Error . 📗 Read the whole article 📅 Events PrageVue 2024 (17 September 2024, Prag, Czech Republic) vuejs.de Conf (8 - 9 October 2024, Bonn, Germany) Vue Fes Japan 2024 (19 October 2024, Otemachi, Japan) VueConf Toronto (18 - 20 November 2024, Toronto, Canada) 💬 Quote of the week 🧑🏻💻 In Other News 📕 How Google handles JavaScript throughout the indexing process 👉🏻 MERJ and Vercel analyzed over 100,000 Googlebot fetches in an attempt to empirically demystify Google’s approach. 📕 Why Unknown Types Are Useful 👉🏻 TypeScript’s unknown, specifically. 📹 Tech Documentaries 👉🏻 Really cool cinematic documentaries on your favourite OSS projects like Vue and TypeScript. 🛠️ Fluid for Tailwind CSS 👉🏻 A shorthand for responsive code in Tailwind to make Tailwind code drier. 😂 Fun 🔗 Want more Vue & Nuxt content?
