From 2c9d5ed65071cdf90bd5d96b5e5ffc36cb9723c6 Mon Sep 17 00:00:00 2001 From: gbanyan Date: Thu, 20 Nov 2025 00:10:26 +0800 Subject: [PATCH] Add full-text search with Chinese tokenization using Pagefind MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Integrated Pagefind for static site search with built-in Chinese word segmentation support. Changes: 1. **Installed Pagefind** (v1.4.0) as dev dependency 2. **Updated build script** to run Pagefind indexing after Next.js build - Indexes all 69 pages with 5,711 words - Automatic Chinese (zh-tw) language detection 3. **Created search modal component** (components/search-modal.tsx) - Dynamic Pagefind UI loading (lazy-loaded on demand) - Keyboard shortcuts (Cmd+K / Ctrl+K) - Chinese translations for UI elements - Dark mode compatible styling 4. **Added search button to header** (components/site-header.tsx) - Integrated SearchButton with keyboard shortcut display - Modal state management 5. **Custom Pagefind styles** (styles/globals.css) - Tailwind-based styling to match site design - Dark mode support - Highlight styling for search results Features: - ✅ Full-text search across all blog posts and pages - ✅ Built-in Chinese word segmentation (Unicode-based) - ✅ Mixed Chinese/English query support - ✅ Zero bundle impact (20KB lazy-loaded on search activation) - ✅ Keyboard shortcuts (⌘K / Ctrl+K) - ✅ Search result highlighting with excerpts - ✅ Dark mode compatible Technical Details: - Pagefind runs post-build to index .next directory - Search index stored in .next/pagefind/ - Chinese segmentation works automatically via Unicode boundaries - No third-party services or API keys required 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- components/search-modal.tsx | 177 ++++++++++++++++++++++++++++++++++++ components/site-header.tsx | 10 ++ package-lock.json | 104 +++++++++++++++++++++ package.json | 5 +- styles/globals.css | 45 +++++++++ 5 files changed, 339 insertions(+), 2 deletions(-) create mode 100644 components/search-modal.tsx diff --git a/components/search-modal.tsx b/components/search-modal.tsx new file mode 100644 index 0000000..704f043 --- /dev/null +++ b/components/search-modal.tsx @@ -0,0 +1,177 @@ +'use client'; + +import { useEffect, useRef, useState } from 'react'; +import { FontAwesomeIcon } from '@fortawesome/react-fontawesome'; +import { faMagnifyingGlass, faXmark } from '@fortawesome/free-solid-svg-icons'; + +interface SearchModalProps { + isOpen: boolean; + onClose: () => void; +} + +export function SearchModal({ isOpen, onClose }: SearchModalProps) { + const [isLoaded, setIsLoaded] = useState(false); + const searchContainerRef = useRef(null); + const pagefindUIRef = useRef(null); + + useEffect(() => { + if (!isOpen) return; + + // Load Pagefind UI dynamically when modal opens + const loadPagefind = async () => { + if (pagefindUIRef.current) { + // Already loaded + return; + } + + try { + // Load Pagefind UI CSS + const link = document.createElement('link'); + link.rel = 'stylesheet'; + link.href = '/pagefind/pagefind-ui.css'; + document.head.appendChild(link); + + // Load Pagefind UI JS + const script = document.createElement('script'); + script.src = '/pagefind/pagefind-ui.js'; + script.onload = () => { + if (searchContainerRef.current && (window as any).PagefindUI) { + pagefindUIRef.current = new (window as any).PagefindUI({ + element: searchContainerRef.current, + showSubResults: true, + showImages: false, + excerptLength: 15, + resetStyles: false, + translations: { + placeholder: '搜尋文章...', + clear_search: '清除', + load_more: '載入更多結果', + search_label: '搜尋此網站', + filters_label: '篩選', + zero_results: '找不到 [SEARCH_TERM] 的結果', + many_results: '找到 [COUNT] 個 [SEARCH_TERM] 的結果', + one_result: '找到 [COUNT] 個 [SEARCH_TERM] 的結果', + alt_search: '找不到 [SEARCH_TERM] 的結果。改為顯示 [DIFFERENT_TERM] 的結果', + search_suggestion: '找不到 [SEARCH_TERM] 的結果。請嘗試以下搜尋：', + searching: '搜尋中...' + } + }); + setIsLoaded(true); + } + }; + document.head.appendChild(script); + } catch (error) { + console.error('Failed to load Pagefind:', error); + } + }; + + loadPagefind(); + }, [isOpen]); + + useEffect(() => { + const handleEscape = (e: KeyboardEvent) => { + if (e.key === 'Escape' && isOpen) { + onClose(); + } + }; + + document.addEventListener('keydown', handleEscape); + return () => document.removeEventListener('keydown', handleEscape); + }, [isOpen, onClose]); + + useEffect(() => { + // Prevent body scroll when modal is open + if (isOpen) { + document.body.style.overflow = 'hidden'; + } else { + document.body.style.overflow = ''; + } + return () => { + document.body.style.overflow = ''; + }; + }, [isOpen]); + + if (!isOpen) return null; + + return ( +
