Asynchronous serverless processing with in-app notifications using QStash and novu

In a tutorial exploring the use of serverless functions for processing tasks with potential failures, the integration of QStash and novu is demonstrated through the creation of a simple app that adds two numbers. This app, although basic in task, showcases the power of QStash as an HTTP-based messaging and scheduling solution, and novu's capability for managing communication channels like email and SMS. The app's serverless function conducts the addition and notifies users of success or failure through novu, highlighting the retry capabilities of QStash. By employing Next.js for development and deploying the app on Vercel, users can experience firsthand how such a setup can handle complex workflows beyond just adding numbers, offering a resilient framework that can automatically retry failed tasks and inform users accordingly. This approach underscores the potential of serverless architectures combined with messaging solutions to handle asynchronous tasks efficiently while minimizing infrastructure management.
