Hello! I'm @Ryo54388667! ☺️

Here are the May release notes!

After Golden Week ended, development resumed in full swing. This month saw significant progress in both internationalization (i18n) and UI/UX improvements, enhancing both quality and usability. The multilingual support implementation, in particular, establishes a crucial foundation for the blog's global expansion.

Application Updates

Internationalization (i18n) Implementation 🌍

To expand the blog globally, we've finally implemented internationalization support! Users can now switch between Japanese and English, allowing us to deliver technical information to a broader audience.

Key Implementation Features:

Locale-based routing using Next.js 14's App Router
SEO-optimized URL path structure: /ja/blogs, /en/blogs
Multilingual support for header navigation, footer, and search functionality
Internationalization of category names and article metadata

// Language switching implementation example
const switchLanguage = (newLocale: string) => {
  const currentPath = pathname.replace(`/${locale}`, '')
  router.push(`/${newLocale}${currentPath}`)
}

After implementation, I thought "the language switcher might be too prominent..." and adjusted it to match the product's color and tone 😇 We ultimately settled on a more natural and user-friendly UI design.

SEO Benefits:

Search engine optimization for each language
Proper multilingual site recognition through hreflang attributes
Language-specific OpenGraph image generation

Code Block Feature Enhancement 💻

We've added convenient features to code blocks, which are essential for technical blogs, to improve the developer experience.

Text Copy Button

Added a one-click code copy button. It's a subtle feature, but one that many readers requested 👌

// Copy functionality implementation
const copyToClipboard = async (text: string) => {
  await navigator.clipboard.writeText(text)
  setIsCopied(true)
  setTimeout(() => setIsCopied(false), 2000)
}

Text Wrap Button

Implemented functionality to wrap long lines of code for display. A user-friendly design for those who dislike horizontal scrolling.

// Wrap button implementation
const toggleWrap = () => {
  setIsWrapped(!isWrapped)
}

// Dynamic CSS class switching
className={`${isWrapped ? 'whitespace-pre-wrap' : 'whitespace-pre'}`}

Initially, we displayed tooltips on click, but changed it to hover for a more intuitive UX.

LLMs Integration Button Addition 🤖

Responding to the AI era, we've added an LLMs (Large Language Models) integration button to the header. This feature is for readers who want to dive deeper into article content with AI assistance.

Implementation Features:

Transparent icon background supporting both dark and light modes
Proper formatting of article content for AI tool integration
User-friendly button placement and design

This feature enables readers who want to understand technical articles more deeply to use AI tools to advance their learning.

List Marker Display Improvement 📝

Fixed an issue where list markers in custom list components would overflow beyond the left margin.

/* Before */
.custom-list {
  list-style: disc;
}

/* After */
.custom-list {
  list-style: disc;
  @apply list-inside; /* Added TailwindCSS list-inside class */
}

While a minor fix, this improvement significantly contributes to readability and layout stability. Such attention to detail leads to enhanced user experience.

Infrastructure Updates

Enhanced SEO Optimization 🔍

We implemented URL path optimization, changing category pages from query parameters to path parameters for a more search engine-friendly structure.

# Before
/blogs?category=tech&page=2

# After  
/blogs/tech/2

Implementation Details:

Utilizing Next.js 14's Dynamic Routes
301 redirect processing from old URLs to new URLs
Automatic sitemap updates
Breadcrumb list improvements

We also implemented redirect processing that preserves existing links, achieving both SEO value inheritance and user experience.

Build-time Optimization ⚡

We expanded the scope of Static Site Generation (SSG) to improve performance.

Main Improvements:

Build-time generation of pagination pages
Reduced initial access response time
Build time optimization by removing unnecessary revalidate processing

// Page generation optimization
export async function generateStaticParams() {
  const totalPages = await getTotalPages()
  return Array.from({ length: totalPages }, (_, i) => ({
    page: (i + 1).toString(),
  }))
}

This significantly improved the perceived speed when users access the site.

Deployment Configuration Improvements 🚀

To improve CI/CD pipeline stability, we implemented the following improvements:

Optimized deploy.yml configuration
Added build error pre-detection functionality
Improved test execution processes
Automatic rollback functionality for deployment failures

These improvements enable safer and more stable deployments. Not only improving developer experience but also significantly enhancing site availability.

Next Month (June) Plans 📅

Major Performance Improvement Project 🚀

Targeting over 8 seconds of performance improvement, we plan to implement the following optimizations:

Enable Text Compression (2.25 seconds improvement expected)
CSS Optimization and Critical CSS Implementation (1.8 seconds improvement expected)
HTTP/2 Enablement (1.7 seconds improvement expected)
JavaScript Bundle Optimization (1.05 seconds improvement expected)
Enhanced Image Optimization (LCP improvement)

Visualization of measurement results integrated with Notion API
Quality management for both mobile and desktop

UI/UX & Accessibility Improvements
