# MarkLite 重构方案：TypeScript + React + IndexedDB
|
||
|
||
## 一、重构目标与原则
|
||
|
||
| 维度 | 现状 | 目标 |
|
||
|------|------|------|
|
||
| 语言 | JavaScript (无类型) | **TypeScript 5.x** (全量类型) |
|
||
| UI 框架 | 原生 DOM 操作 | **React 18** (函数组件 + Hooks) |
|
||
| 状态管理 | 全局变量 + 闭包 | **Zustand** (轻量状态管理) |
|
||
| 持久化 | localStorage | **IndexedDB** (via Dexie.js) |
|
||
| 样式 | 纯 CSS | **CSS Modules** + CSS 变量 |
|
||
| 构建 | 无打包 | **Vite** + electron-vite |
|
||
| Markdown | marked.min.js (离线) | **unified/remark/rehype** 生态 |
|
||
| 代码高亮 | highlight.js (离线) | **Shiki** 或 **rehype-highlight** |
|
||
| 编辑器 | `<textarea>` | **CodeMirror 6** (专业编辑器) |
|
||
|
||
**核心原则**：
|
||
|
||
1. **功能 100% 兼容** — 不丢失任何现有功能
|
||
2. **渐进式重构** — 主进程/预加载脚本改动最小，重点重构渲染进程
|
||
3. **类型安全** — 所有接口、IPC 通信、状态都有 TypeScript 类型
|
||
4. **可测试性** — 业务逻辑与 UI 解耦，便于单元测试
|
||
|

||
## 三、技术选型详解
|
||
|
||
### 1. TypeScript — 类型安全
|
||
|
||
```typescript
|
||
// src/renderer/types/tab.ts
|
||
export interface Tab {
|
||
id: string; // nanoid 生成
|
||
filePath: string | null;
|
||
content: string;
|
||
isModified: boolean;
|
||
scrollTop: number;
|
||
scrollLeft: number;
|
||
selectionStart: number;
|
||
selectionEnd: number;
|
||
previewScrollTop: number;
|
||
}
|
||
|
||
// src/renderer/types/ipc.ts — IPC 通道类型映射
|
||
export interface IpcInvokeMap {
|
||
'dialog:openFile': [void, OpenFileResult | null];
|
||
'file:read': [string, ReadFileResult];
|
||
'file:save': [SaveFilePayload, SaveFileResult];
|
||
'file:saveAs': [SaveAsPayload, SaveFileResult];
|
||
'file:reload': [void, ReloadFileResult];
|
||
'dir:readTree': [string, ReadDirTreeResult];
|
||
'dir:openDialog': [void, string | null];
|
||
'dir:watch': [string, void];
|
||
'tab:switched': [string | null, void];
|
||
'window:forceClose': [void, void];
|
||
}
|
||
|
||
// 类型安全的 IPC 调用封装
|
||
export function invoke<K extends keyof IpcInvokeMap>(
|
||
channel: K,
|
||
...args: IpcInvokeMap[K][0] extends void ? [] : [IpcInvokeMap[K][0]]
|
||
): Promise<IpcInvokeMap[K][1]> {
|
||
return window.electronAPI.invoke(channel, ...args);
|
||
}
|
||
```
|
||
|
||
### 2. Zustand — 状态管理
|
||
|
||
```typescript
|
||
// src/renderer/stores/tabStore.ts
|
||
import { create } from 'zustand';
|
||
import { nanoid } from 'nanoid';
|
||
import type { Tab } from '../types/tab';
|
||
|
||
interface TabState {
|
||
tabs: Tab[];
|
||
activeTabId: string | null;
|
||
mruStack: string[];
|
||
|
||
// Actions
|
||
createTab: (filePath?: string | null, content?: string) => Tab;
|
||
closeTab: (tabId: string) => void;
|
||
switchToTab: (tabId: string) => void;
|
||
updateTabContent: (tabId: string, content: string) => void;
|
||
setModified: (tabId: string, modified: boolean) => void;
|
||
getActiveTab: () => Tab | null;
|
||
}
|
||
|
||
export const useTabStore = create<TabState>((set, get) => ({
|
||
tabs: [],
|
||
activeTabId: null,
|
||
mruStack: [],
|
||
|
||
createTab: (filePath = null, content = '') => {
|
||
// 检查是否已打开
|
||
if (filePath) {
|
||
const existing = get().tabs.find(t => t.filePath === filePath);
|
||
if (existing) {
|
||
get().switchToTab(existing.id);
|
||
return existing;
|
||
}
|
||
}
|
||
|
||
const tab: Tab = {
|
||
id: nanoid(),
|
||
filePath,
|
||
content,
|
||
isModified: false,
|
||
scrollTop: 0,
|
||
scrollLeft: 0,
|
||
selectionStart: 0,
|
||
selectionEnd: 0,
|
||
previewScrollTop: 0,
|
||
};
|
||
|
||
set(state => ({
|
||
tabs: [...state.tabs, tab],
|
||
activeTabId: tab.id,
|
||
}));
|
||
|
||
return tab;
|
||
},
|
||
|
||
closeTab: (tabId) => {
|
||
set(state => {
|
||
const index = state.tabs.findIndex(t => t.id === tabId);
|
||
if (index === -1) return state;
|
||
|
||
const newTabs = state.tabs.filter(t => t.id !== tabId);
|
||
const newMru = state.mruStack.filter(id => id !== tabId);
|
||
|
||
let newActiveId = state.activeTabId;
|
||
if (state.activeTabId === tabId) {
|
||
if (newTabs.length === 0) {
|
||
newActiveId = null;
|
||
} else {
|
||
const newIndex = Math.min(index, newTabs.length - 1);
|
||
newActiveId = newTabs[newIndex].id;
|
||
}
|
||
}
|
||
|
||
return {
|
||
tabs: newTabs,
|
||
activeTabId: newActiveId,
|
||
mruStack: newMru,
|
||
};
|
||
});
|
||
},
|
||
|
||
switchToTab: (tabId) => {
|
||
set(state => {
|
||
if (state.activeTabId === tabId) return state;
|
||
return {
|
||
activeTabId: tabId,
|
||
mruStack: [
|
||
state.activeTabId!,
|
||
...state.mruStack.filter(id => id !== state.activeTabId),
|
||
],
|
||
};
|
||
});
|
||
},
|
||
|
||
updateTabContent: (tabId, content) => {
|
||
set(state => ({
|
||
tabs: state.tabs.map(t =>
|
||
t.id === tabId ? { ...t, content, isModified: true } : t
|
||
),
|
||
}));
|
||
},
|
||
|
||
setModified: (tabId, modified) => {
|
||
set(state => ({
|
||
tabs: state.tabs.map(t =>
|
||
t.id === tabId ? { ...t, isModified: modified } : t
|
||
),
|
||
}));
|
||
},
|
||
|
||
getActiveTab: () => {
|
||
const { tabs, activeTabId } = get();
|
||
return tabs.find(t => t.id === activeTabId) ?? null;
|
||
},
|
||
}));
|
||
```
|
||
|
||
### 3. IndexedDB (Dexie.js) — 持久化
|
||
|
||
```typescript
|
||
// src/renderer/db/schema.ts
|
||
import Dexie, { type EntityTable } from 'dexie';
|
||
|
||
interface TabSnapshot {
|
||
id: string; // 与 Tab.id 对应
|
||
filePath: string | null;
|
||
content: string;
|
||
scrollTop: number;
|
||
scrollLeft: number;
|
||
selectionStart: number;
|
||
selectionEnd: number;
|
||
previewScrollTop: number;
|
||
isModified: boolean;
|
||
updatedAt: number; // 时间戳
|
||
}
|
||
|
||
interface Settings {
|
||
id: string; // 固定为 'default'
|
||
darkMode: boolean;
|
||
viewMode: 'split' | 'editor' | 'preview';
|
||
splitRatio: number;
|
||
sidebarCollapsed: boolean;
|
||
sidebarWidth: number;
|
||
}
|
||
|
||
interface RecentFile {
|
||
id?: number; // 自增主键
|
||
filePath: string;
|
||
lastOpened: number;
|
||
}
|
||
|
||
const db = new Dexie('MarkLite') as Dexie & {
|
||
tabSnapshots: EntityTable<TabSnapshot, 'id'>;
|
||
settings: EntityTable<Settings, 'id'>;
|
||
recentFiles: EntityTable<RecentFile, 'id'>;
|
||
};
|
||
|
||
db.version(1).stores({
|
||
tabSnapshots: 'id, filePath, updatedAt',
|
||
settings: 'id',
|
||
recentFiles: '++id, filePath, lastOpened',
|
||
});
|
||
|
||
export { db };
|
||
export type { TabSnapshot, Settings, RecentFile };
|
||
```
|
||
|
||
```typescript
|
||
// src/renderer/db/tabRepository.ts
|
||
import { db, type TabSnapshot } from './schema';
|
||
|
||
export const tabRepository = {
|
||
/** 保存所有标签快照（关闭时/定期） */
|
||
async saveAll(tabs: TabSnapshot[]): Promise<void> {
|
||
await db.transaction('rw', db.tabSnapshots, async () => {
|
||
await db.tabSnapshots.clear();
|
||
await db.tabSnapshots.bulkAdd(tabs);
|
||
});
|
||
},
|
||
|
||
/** 加载上次的标签快照 */
|
||
async loadAll(): Promise<TabSnapshot[]> {
|
||
return db.tabSnapshots.orderBy('updatedAt').toArray();
|
||
},
|
||
|
||
/** 清除所有快照（用户主动清除时） */
|
||
async clearAll(): Promise<void> {
|
||
await db.tabSnapshots.clear();
|
||
},
|
||
};
|
||
```
|
||
|
||
### 4. CodeMirror 6 — 编辑器
|
||
|
||
```typescript
|
||
// src/renderer/components/Editor/useCodeMirror.ts
|
||
import { useEffect, useRef, useCallback } from 'react';
|
||
import { EditorState, type Extension } from '@codemirror/state';
|
||
import { EditorView, keymap, lineNumbers, highlightActiveLine } from '@codemirror/view';
|
||
import { defaultKeymap, history, historyKeymap } from '@codemirror/commands';
|
||
import { markdown, markdownLanguage } from '@codemirror/lang-markdown';
|
||
import { syntaxHighlighting, defaultHighlightStyle } from '@codemirror/language';
|
||
import { oneDark } from '@codemirror/theme-one-dark';
|
||
|
||
interface UseCodeMirrorOptions {
|
||
content: string;
|
||
onChange: (value: string) => void;
|
||
darkMode: boolean;
|
||
}
|
||
|
||
export function useCodeMirror({ content, onChange, darkMode }: UseCodeMirrorOptions) {
|
||
const containerRef = useRef<HTMLDivElement>(null);
|
||
const viewRef = useRef<EditorView | null>(null);
|
||
|
||
// 初始化
|
||
useEffect(() => {
|
||
if (!containerRef.current) return;
|
||
|
||
const extensions: Extension[] = [
|
||
lineNumbers(),
|
||
highlightActiveLine(),
|
||
history(),
|
||
keymap.of([...defaultKeymap, ...historyKeymap]),
|
||
markdown({ base: markdownLanguage }),
|
||
syntaxHighlighting(defaultHighlightStyle),
|
||
EditorView.updateListener.of(update => {
|
||
if (update.docChanged) {
|
||
onChange(update.state.doc.toString());
|
||
}
|
||
}),
|
||
EditorView.lineWrapping,
|
||
];
|
||
|
||
if (darkMode) extensions.push(oneDark);
|
||
|
||
const state = EditorState.create({
|
||
doc: content,
|
||
extensions,
|
||
});
|
||
|
||
const view = new EditorView({
|
||
state,
|
||
parent: containerRef.current,
|
||
});
|
||
|
||
viewRef.current = view;
|
||
|
||
return () => {
|
||
view.destroy();
|
||
viewRef.current = null;
|
||
};
|
||
}, [darkMode]); // darkMode 变化时重建
|
||
|
||
// 外部内容更新（切换标签时）
|
||
const setContent = useCallback((newContent: string) => {
|
||
const view = viewRef.current;
|
||
if (!view) return;
|
||
const current = view.state.doc.toString();
|
||
if (current !== newContent) {
|
||
view.dispatch({
|
||
changes: { from: 0, to: current.length, insert: newContent },
|
||
});
|
||
}
|
||
}, []);
|
||
|
||
return { containerRef, viewRef, setContent };
|
||
}
|
||
```
|
||
|
||
### 5. Markdown 渲染管线
|
||
|
||
```typescript
|
||
// src/renderer/lib/markdown.ts
|
||
import { unified } from 'unified';
|
||
import remarkParse from 'remark-parse';
|
||
import remarkGfm from 'remark-gfm';
|
||
import remarkRehype from 'remark-rehype';
|
||
import rehypeRaw from 'rehype-raw';
|
||
import rehypeSanitize, { defaultSchema } from 'rehype-sanitize';
|
||
import rehypeStringify from 'rehype-stringify';
|
||
import rehypeHighlight from 'rehype-highlight';
|
||
|
||
const processor = unified()
|
||
.use(remarkParse)
|
||
.use(remarkGfm)
|
||
.use(remarkRehype, { allowDangerousHtml: true })
|
||
.use(rehypeRaw)
|
||
.use(rehypeSanitize, {
|
||
...defaultSchema,
|
||
attributes: {
|
||
...defaultSchema.attributes,
|
||
img: [...(defaultSchema.attributes?.img ?? []), ['src']],
|
||
},
|
||
})
|
||
.use(rehypeHighlight)
|
||
.use(rehypeStringify);
|
||
|
||
export async function renderMarkdown(content: string): Promise<string> {
|
||
const result = await processor.process(content);
|
||
return String(result);
|
||
}
|
||
```
|
||
|
||

|
||
|
||
## 四、IndexedDB 替代 localStorage 的数据模型
|
||
|
||
| 原 localStorage Key | IndexedDB Store | 字段 | 说明 |
|
||
|---------------------|-----------------|------|------|
|
||
| `marklite-settings` | `settings` | darkMode, viewMode, splitRatio, sidebarCollapsed, sidebarWidth | 用户偏好 |
|
||
| *(无，标签状态丢失)* | `tabSnapshots` | id, filePath, content, scrollTop, ... | **新增**：标签页状态持久化 |
|
||
| *(无)* | `recentFiles` | filePath, lastOpened | **新增**：最近打开文件列表 |
|
||
|
||
**IndexedDB 优势**：
|
||
|
||
- 存储容量大（localStorage 约 5-10MB，IndexedDB 可达数百 MB）
|
||
- 支持大文件内容缓存（当前 20MB 限制的文件也能存）
|
||
- 支持索引查询（按 filePath、updatedAt 查询）
|
||
- 异步 API，不阻塞 UI
|
||
- 标签页状态可持久化（关闭窗口后恢复所有标签）
|
||
|

## 六、主进程重构（改动最小）
|
||
|
||
主进程保持 Electron 原生，仅将 JS → TS，逻辑不变：
|
||
|
||
```typescript
|
||
// src/main/file-system.ts — 类型安全的文件操作
|
||
import { readFile, writeFile, stat, readdir } from 'fs/promises';
|
||
import { join, extname } from 'path';
|
||
import type { FileNode, ReadFileResult, SaveFileResult } from '../shared/types';
|
||
|
||
const ALLOWED_EXTENSIONS = ['.md', '.markdown', '.txt'] as const;
|
||
const MAX_FILE_SIZE = 20 * 1024 * 1024; // 20MB
|
||
|
||
export async function readFileContent(filePath: string): Promise<ReadFileResult> {
|
||
const stats = await stat(filePath);
|
||
if (stats.size > MAX_FILE_SIZE) {
|
||
return { success: false, error: `文件过大 (${formatBytes(stats.size)})` };
|
||
}
|
||
let content = await readFile(filePath, 'utf-8');
|
||
// 去除 BOM
|
||
if (content.charCodeAt(0) === 0xFEFF) content = content.slice(1);
|
||
return { success: true, content };
|
||
}
|
||
|
||
export async function buildDirTree(dirPath: string): Promise<FileNode[]> {
|
||
const entries = await readdir(dirPath, { withFileTypes: true });
|
||
const result: FileNode[] = [];
|
||
|
||
for (const entry of entries) {
|
||
if (shouldSkip(entry.name)) continue;
|
||
const fullPath = join(dirPath, entry.name);
|
||
|
||
if (entry.isDirectory()) {
|
||
result.push({
|
||
name: entry.name,
|
||
path: fullPath,
|
||
type: 'dir',
|
||
children: await buildDirTree(fullPath),
|
||
});
|
||
} else if (ALLOWED_EXTENSIONS.includes(extname(entry.name).toLowerCase() as any)) {
|
||
result.push({ name: entry.name, path: fullPath, type: 'file' });
|
||
}
|
||
}
|
||
|
||
return result.sort((a, b) => {
|
||
if (a.type !== b.type) return a.type === 'dir' ? -1 : 1;
|
||
return a.name.localeCompare(b.name);
|
||
});
|
||
}
|
||
```
|
||
|
||
---
|
||
|
||
## 七、滚动同步算法（保留现有逻辑）
|
||
|
||
现有基于**块级元素 DOM 位置映射**的算法非常优秀，直接用 TypeScript 重写：
|
||
|
||
```typescript
|
||
// src/renderer/lib/scrollSync.ts
|
||
interface ScrollMap {
|
||
lineToPreviewMap: number[];
|
||
}
|
||
|
||
export function buildScrollMap(
|
||
markdown: string,
|
||
previewContainer: HTMLElement
|
||
): ScrollMap {
|
||
const lines = markdown.split('\n');
|
||
const totalLines = lines.length;
|
||
const lineToPreviewMap = new Array(totalLines).fill(0);
|
||
|
||
// 1. 识别块级元素起始行
|
||
const blockStarts = identifyBlockStarts(lines);
|
||
|
||
// 2. 获取预览 DOM 元素位置
|
||
const previewPositions = getPreviewPositions(previewContainer);
|
||
|
||
// 3. 块起始行 → 预览位置映射
|
||
// 4. 线性插值填充中间行
|
||
interpolateBlockPositions(blockStarts, previewPositions, lineToPreviewMap, totalLines);
|
||
|
||
return { lineToPreviewMap };
|
||
}
|
||
|
||
function identifyBlockStarts(lines: string[]): Set<number> {
|
||
const starts = new Set<number>();
|
||
let inCodeBlock = false;
|
||
|
||
for (let i = 0; i < lines.length; i++) {
|
||
const line = lines[i].trim();
|
||
if (line.match(/^```/)) {
|
||
if (!inCodeBlock) starts.add(i);
|
||
inCodeBlock = !inCodeBlock;
|
||
continue;
|
||
}
|
||
if (inCodeBlock) continue;
|
||
if (line.match(/^#{1,6}\s/) || line.match(/^[-*+]\s/) || line.match(/^\d+\.\s/) ||
|
||
line.match(/^>/) || line.match(/^\|/) || line.match(/^---/) || line === '') {
|
||
starts.add(i);
|
||
}
|
||
}
|
||
return starts;
|
||
}
|
||
```
|
||
|

|
||
|
||
## 八、CSS Modules + CSS 变量
|
||
|
||
```css
|
||
/* src/renderer/styles/variables.css */
|
||
:root {
|
||
/* 亮色主题 */
|
||
--color-primary: #1a73e8;
|
||
--color-primary-dark: #1557b0;
|
||
--color-primary-light: rgba(26, 115, 232, 0.1);
|
||
--color-bg: #ffffff;
|
||
--color-bg-secondary: #f8f9fa;
|
||
--color-bg-tertiary: #f1f3f4;
|
||
--color-text: #333333;
|
||
--color-text-secondary: #5f6368;
|
||
--color-text-tertiary: #80868b;
|
||
--color-border: #e1e4e8;
|
||
--color-border-light: #f0f0f0;
|
||
--color-code-bg: #f6f8fa;
|
||
|
||
/* 布局 */
|
||
--toolbar-height: 36px;
|
||
--tabbar-height: 34px;
|
||
--statusbar-height: 24px;
|
||
--sidebar-width: 220px;
|
||
|
||
/* 字体 */
|
||
--font-ui: system-ui, -apple-system, "Segoe UI", Roboto, sans-serif;
|
||
--font-mono: "Cascadia Code", "Fira Code", "JetBrains Mono", Consolas, monospace;
|
||
--font-size: 14px;
|
||
|
||
/* 圆角/阴影 */
|
||
--radius: 6px;
|
||
--shadow-sm: 0 1px 2px rgba(0,0,0,0.05);
|
||
--shadow-lg: 0 4px 12px rgba(0,0,0,0.15);
|
||
}
|
||
|
||
:root.dark {
|
||
--color-primary: #8ab4f8;
|
||
--color-primary-dark: #669df6;
|
||
--color-primary-light: rgba(138, 180, 248, 0.15);
|
||
--color-bg: #1e1e1e;
|
||
--color-bg-secondary: #252526;
|
||
--color-bg-tertiary: #2d2d2d;
|
||
--color-text: #d4d4d4;
|
||
--color-text-secondary: #9e9e9e;
|
||
--color-text-tertiary: #6e6e6e;
|
||
--color-border: #3e3e3e;
|
||
--color-border-light: #333333;
|
||
--color-code-bg: #2d2d2d;
|
||
}
|
||
```
|
||
|

|
||
|
||
## 九、构建配置
|
||
|
||
```typescript
|
||
// electron.vite.config.ts
|
||
import { defineConfig, externalizeDepsPlugin } from 'electron-vite';
|
||
import react from '@vitejs/plugin-react';
|
||
|
||
export default defineConfig({
|
||
main: {
|
||
plugins: [externalizeDepsPlugin()],
|
||
build: {
|
||
outDir: 'dist/main',
|
||
rollupOptions: {
|
||
input: { index: 'src/main/index.ts' },
|
||
},
|
||
},
|
||
},
|
||
preload: {
|
||
plugins: [externalizeDepsPlugin()],
|
||
build: {
|
||
outDir: 'dist/preload',
|
||
rollupOptions: {
|
||
input: { index: 'src/preload/index.ts' },
|
||
},
|
||
},
|
||
},
|
||
renderer: {
|
||
plugins: [react()],
|
||
root: 'src/renderer',
|
||
build: {
|
||
outDir: 'dist/renderer',
|
||
rollupOptions: {
|
||
input: { index: 'src/renderer/index.html' },
|
||
},
|
||
},
|
||
},
|
||
});
|
||
```
|
||
|
||
```json
