TechsFree Website Major Redesign — Trilingual SPA and Blog Integration

techsfree-web-02: TechsFree Website Major Redesign — Trilingual SPA & Blog Integration

Why the Redesign

The TechsFree website (/www/wwwroot/techsfree.com/) was originally a basic static page. Redesign goals: a complete corporate website experience, Chinese/Japanese/English trilingual support, integrated blog system, and content depth befitting an IT company.

Server environment: PHP 7.4 + Nginx, port 8080. Note: PHP 7.4 lacks str_starts_with() / str_ends_with(), requiring strncmp() and substr() workarounds (added in PHP 8.0).

Architecture

Single-file SPA (following Dashboard's design language):

• Left-side fixed navigation + clock + calendar
• 6 main views: Home / Services / Blog / Demo / About / Contact
• Blog sidebar with category submenus and count badges

Blog System:

• Backend /blog/api.php, supporting action=list|get|categories
• Data source: /www/wwwroot/techsfree.com/blog/translations/ directory (73 en + 73 ja articles, synced from jack's translation output)
• Category mapping:
  • joe-* → AI Platform
  • techsfree-web-* → Web Dev
  • health* → Health
  • techsfree-fr-* → Business

Trilingual i18n:

• I18N object manages all UI text
• applyLang() full refresh, renderDynamic() re-renders dynamic content
• Language preference persisted in localStorage.tf_lang
• Calendar weekday headers and clock date formats switch with language (中文/日本語曜日/English Short)

Content Building

Not just technical changes — content was built out simultaneously:

Homepage: Hero banner + 4 stats (projects / active Agents / cities covered / satisfaction rate) + 6 service cards + latest article preview + tech stack grid

Services: 6 detailed service descriptions (AI Agent customization / Enterprise systems / Bot deployment / Data platforms / Web development / Tech consulting)

Demo: 4 real projects (Operations Dashboard / ERP / OpenClaw / Dashboard 2.0) with tech tags and access links

About: Company intro + 4 core values + 5 milestone timeline + 4 team members

A Debugging Detail

Blog API returned total=99 but only 73 articles existed — extras were empty slug files. PHP 7.4's scandir() includes . and .., requiring filtering. Also, the filename format {slug}.{lang}.md needs splitting by language suffix — can't just explode('.', $filename) since filenames may contain dots.

Final code size: 71KB → 84KB (+1507 lines), Blog system integrated with 73 × 2 language articles.
