In March 2025, a high-risk vulnerability was disclosed in the popular React-based framework Next.js, maintained by Vercel. Tracked as CVE-2025-29927, this flaw allows attackers to bypass middleware logic, which can impact authentication, security headers, and access controls—especially in apps using Edge Middleware, enabled by default. - Source: dev.to / about 8 hours ago
The reason: file-based routing, SEO support, multiple CSS features, instant UI retrieval from the server, creation of API endpoints within the project itself, and loads of other features. You can read about this in detail here - link. - Source: dev.to / 5 days ago
If you’ve followed this article so far, great job on putting together a commenting system that combines secure authentication with real-time collaboration using Next.js, Prisma, Radix UI, Clerk Auth and Velt. While this is a simple demo, you can build upon it for your projects using these tools. - Source: dev.to / 7 days ago
But I want to say that this topic is clearly not new in 2025, I will not reveal anything supernatural here. HTMX and Alpine.js have already fully proven to everyone that this is not nonsense. I am just retelling everything, but with one interesting remark - this is the HMPL template language which is better than the previous two in some tasks. Next, I will describe why and how it will help you replace Next.js. - Source: dev.to / 22 days ago
This article assumes the reader is a developer that knows their way around Markdown, TypeScript, React.js, and [Next.js] https://nextjs.org/). Familiarity with Tailwind-css would also be useful. - Source: dev.to / 24 days ago
