You can definitely use Next.js API routes to handle Discord interactions, and it's a good idea if you're already familiar with Next.js. The Discord API is just a regular API, so you can use Next.js to create endpoints that interact with it. However, you might run into some limitations, like having to handle webhooks and potentially long-running tasks, which can be tricky with Next.js. A dedicated Node.js bot framework like discord.js might be more straightforward for certain tasks, but if you're comfortable with Next.js, you can make it work. You just need to consider how you'll handle things like bot authentication and message processing.
