After years of running this blog on Gatsby, I recently made the leap to Next.js. This migration wasn't just a simple framework swap—it represented a complete modernization of the blog's architecture, tooling, and user experience. Here's a deep dive into what changed and why.

The Migration Foundation

The migration itself was substantial, moving from Gatsby's static site generation approach to Next.js 13+ with the App Router. This wasn't just about swapping one React framework for another; it involved rethinking how content is processed, how pages are generated, and how the overall developer experience works.

Key Architectural Changes

Content Processing: The blog moved from Gatsby's GraphQL-based content layer to a more direct approach using gray-matter for frontmatter parsing and custom utilities in src/lib/blog.ts. This simplified the content pipeline while maintaining all the flexibility needed for a developer blog.

Routing: Transitioned from Gatsby's automatic page generation to Next.js App Router with dynamic routes at src/app/blog/[slug]/page.tsx. This provides better control over how individual blog posts are rendered and cached.

Static Generation: Maintained the benefits of static site generation but with Next.js's more modern approach, ensuring fast loading times while getting better developer tooling.

Post-Migration Enhancements

Since the initial migration, the blog has seen several significant improvements that showcase the flexibility of the new architecture:

1. Modern Terminal-Inspired Design

The most visible change has been a complete design overhaul. The new look embraces a terminal/code editor aesthetic with:

• Dark theme throughout with gray-900 backgrounds and syntax-highlighted colors
• Monospace typography using a clean, readable font stack
• Terminal-style navigation with commands like $ home, $ contact, etc.
• Sidebar layouts that mimic code editor interfaces with navigation and utility panels

This design isn't just aesthetic—it reflects the technical nature of the content and creates a cohesive experience for developers reading the blog.

2. Enhanced Page Structure

The blog now includes several new pages that weren't part of the original Gatsby setup:

Contact Page (src/app/contact/page.tsx): A terminal-themed contact interface that presents information in a developer-friendly format with commands like $ cat contact.info and $ ls -la ./interests.

Sitemap Page (src/app/sitemap/page.tsx): A comprehensive site map that displays all posts, pages, and tags in a tree-like structure reminiscent of the Unix tree command.

3. Advanced Content Management Tooling

One of the most significant additions is the custom blog management CLI tool (scripts/blog.js). This Node.js script provides:

• Post Creation: Interactive post creation with title input and publication status
• Post Editing: Browse and select from existing posts to edit
• Global Configuration: Setup for running the blog command from anywhere on the system
• Smart Project Detection: Automatically finds the blog project root using multiple strategies

The CLI tool demonstrates sophisticated project management features:

• Environment variable support (BLOG_PROJECT_ROOT)
• Home directory config file (~/.blog-config.json)
• Automatic project root detection by scanning for package.json and the content/blog directory
• Integration with system editors via the EDITOR environment variable

4. Improved Navigation and User Experience

The new architecture supports enhanced navigation features:

Adjacent Post Links: Blog posts now include navigation to previous and next posts, implemented with utility functions in src/lib/blog.ts that calculate post relationships.

Better Typography: The typography has been completely overhauled with proper spacing, readable font sizes, and consistent styling throughout.

Responsive Design: While maintaining the terminal aesthetic, the design works well across different screen sizes with appropriate sidebar behavior.

Technical Improvements Under the Hood

Beyond the visible changes, several technical improvements make the blog more maintainable and performant:

Type Safety

The migration introduced comprehensive TypeScript definitions in src/types/blog.ts, ensuring type safety throughout the content processing pipeline.

Modern Build Pipeline

Next.js provides a more modern build system with better optimization, automatic code splitting, and improved development experience.

Simplified Deployment

The blog maintains its Netlify deployment setup but benefits from Next.js's optimized build output and better caching strategies.

Lessons Learned

This migration highlighted several important considerations for static site modernization:

1. Framework Choice Matters: While Gatsby served well initially, Next.js's App Router provides more flexibility for custom content management and better alignment with modern React patterns.

2. Design and Function Integration: The terminal-themed design isn't just visual—it creates opportunities for creative technical content presentation that aligns with the blog's developer audience.

3. Tooling Investment: The custom CLI tool significantly improves the content creation workflow, demonstrating how investing in developer experience pays dividends in productivity.

4. Incremental Enhancement: The ability to enhance the blog post-migration with new pages, improved styling, and better tooling shows the value of choosing a flexible foundation.

Looking Forward

The migration to Next.js has positioned the blog for future enhancements. The modern architecture makes it easier to:

• Add new interactive features
• Integrate with external APIs or services
• Implement advanced content features like search or filtering
• Experiment with new design patterns

This evolution from Gatsby to Next.js represents more than a technical migration—it's a complete modernization that improves both the developer experience and the reader experience. The terminal-inspired design, custom tooling, and enhanced navigation create a cohesive platform that better serves its purpose as a developer-focused blog.

The journey from a simple Gatsby blog to this modern Next.js-powered platform demonstrates how thoughtful technical decisions can enable creative expression while maintaining excellent performance and maintainability.
