Hacker News commenters largely debated the merits of Next.js vs. Rails, with many arguing that the article presented a skewed comparison. Several pointed out that the performance issues described likely stemmed from suboptimal Next.js implementations, particularly regarding server-side rendering and caching, rather than inherent framework limitations. Others echoed the article's sentiment about the simplicity and developer experience of Rails, while acknowledging Next.js's strengths for complex frontends. A few commenters suggested alternative approaches like using Rails as an API backend for a separate frontend framework, or using Hotwire with Rails for a more streamlined approach. The overall consensus leaned towards choosing the right tool for the job, recognizing that both frameworks have their strengths and weaknesses depending on the specific project requirements.
HTML is designed for structuring content, not for complex logic like file inclusion. Including external files requires fetching and parsing them, a task handled by the server (server-side includes) or the browser (client-side JavaScript). While templating languages and build tools can pre-process HTML with includes, native HTML lacks the capability because it prioritizes simplicity, performance, and security. Implementing includes directly in HTML would introduce significant complexity, potentially impacting rendering speed and opening up security vulnerabilities if HTML files could arbitrarily execute external scripts. Therefore, the responsibility of assembling the final HTML document typically falls to other tools and technologies better suited to handle the complexities involved.
Hacker News users discuss the limitations of native HTML includes and the reasons behind them. Several commenters point to the complexity of implementing a robust include system within the browser, particularly regarding caching, dependency management, and potential security vulnerabilities. One highly upvoted comment suggests that the desire for includes often stems from a misunderstanding of HTML's purpose as a document format, not a programming language. Others argue that server-side includes (SSI) and build tools effectively address the need for modularity during development, making browser-native includes unnecessary. The lack of standardization and potential performance issues are also cited as reasons for the absence of this feature. Some commenters express a preference for using JavaScript and build tools, while others lament the added complexity this introduces. The historical context of frames and iframes is also brought up, highlighting their shortcomings and why they aren't suitable replacements for true includes.

This concern reflects a broader skepticism about the necessity of switching to a new tool without clear evidence of significant performance gains.
Some commenters express interest in the integrated approach of Biome.js, appreciating the potential for a more streamlined development workflow. They acknowledge the frustration of managing separate configurations for linting and formatting, suggesting that a unified tool could simplify project setup and maintenance. However, even those expressing interest also voice caution, emphasizing the importance of careful evaluation and community adoption before considering a migration in a production environment.
One commenter specifically highlights the potential for "vendor lock-in" with Biome.js, expressing concern about the risks associated with relying on a relatively new and less established tool. They raise the question of long-term maintenance and support, particularly in the event that the project loses momentum or faces unforeseen challenges.
Finally, some commenters mention alternative tools like Rome and Deno's built-in linting and formatting capabilities, further highlighting the evolving landscape of JavaScript tooling and the ongoing search for optimal development workflows. This suggests that while Biome.js presents an interesting alternative, it enters a competitive field with several established and emerging players.
