Next.js features and specs

  • Server-Side Rendering (SSR)
    Next.js supports SSR, allowing pages to be rendered on the server-side before being sent to the client. This results in improved SEO and faster initial page loads.
  • Static Site Generation (SSG)
    Enables pre-rendering pages at build time, which can further improve performance and scalability while allowing for dynamic generation when needed.
  • API Routes
    Next.js allows you to build API endpoints directly in the application, simplifying the process of creating back-end services and endpoints.
  • File-Based Routing
    Offers a simple file-based routing mechanism where the file structure maps directly to the app’s routes, making it easier to manage and understand.
  • Automatic Code Splitting
    Automatically splits code at the page level, reducing the initial load time and improving performance by only loading necessary JavaScript.
  • TypeScript Support
    Built-in support for TypeScript, allowing developers to use static type checking and other TypeScript features easily.
  • Developer Experience
    Provides a great developer experience with features like fast refresh, hot reloading, and detailed error reporting.
  • Rich Ecosystem
    Benefiting from the rich ecosystem of the React community and integrating well with other libraries and tools.
  • Internationalization
    Built-in support for internationalization helps developers build multilingual applications with ease.
  • Community and Support
    Strong community and extensive documentation provide ample support and resources for new and experienced developers alike.

Possible disadvantages of Next.js

  • Learning Curve
    The robust feature set of Next.js can present a steep learning curve for developers who are new to React or server-side rendering concepts.
  • Configuration Overhead
    Although Next.js aims for simplicity, complex projects may still require significant configuration and customization.
  • Performance Overhead
    SSR can introduce additional server load and latency compared to static site generators, especially under high traffic conditions.
  • Deployment Complexity
    Deploying Next.js applications that leverage SSR or API routes may be more complex and could require more sophisticated server infrastructure.
  • Vendor Lock-In
    If heavily relying on Next.js-specific features, moving away from the framework to another solution could require significant refactoring.
  • Bundle Size
    Without careful optimization, client-side bundle sizes can become large, negatively affecting the application’s performance.
  • Build Times
    For large applications, build times can be significant, impacting the development cycle and deployment times.
  • Dependencies
    Next.js introduces its own set of dependencies and tooling, which might complicate version management and compatibility with other tools.

  • I replaced Next.js for my application with this module 🔥
    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

  • What is the role of QoS for Pods?
    There are tools CastAI (https://cast.ai/) and KubeCost (https://www.kubecost.com/) which helps you get these values. I haven't tried it personally, but they are promising. There are other tools as well. One of the approach OP suggested, monitor the values over a period of time to determine the right requests value, is really good one. I would modify it a bit. Generally take the p95 value for requests and 1.5-2x... Source: almost 2 years ago

    Curious about what about cast.ai sets it apart for you? I went with spot because it is owned by a big company and knew it wasn't going to disappear. I think cast was still in invite only mode, as well. Source: over 2 years ago
