Form validation with Next.js and Netlify

Building serverless forms is becoming increasingly feasible with advancements in JAMStack technologies and serverless approaches, allowing for tasks traditionally requiring a backend to be managed on the frontend or through APIs. This article explores creating fully serverless forms using Netlify Lambda functions, which facilitate running server-side code with minimal configuration and integrate well with Next.js. The process involves setting up a Next.js project, utilizing libraries such as React Hook Form for client-side validation and Yup for schema validation, and connecting to a MongoDB database to store form data. The serverless functions, designed to execute on-demand, allow scalability without requiring continuous runtime, and a detailed guide is provided on implementing these using Netlify. By leveraging these technologies, developers can create efficient, scalable forms while minimizing backend dependencies, enhancing the overall capabilities of web applications.
