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: 1import { z } from 'zod'; 2 3const 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: 1export 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?
