参考：
electron 网页TodoList工具打包成win桌面应用exe

electron直接打包exe应用，打开网页上面添加的task在重启后为空，历史没有被保存，需要持久化工具保存之前的操作记录

这里测试用electron-store或electron-conf两个持久化工具运行都ESM报错：

在这里插入图片描述

解决方法：
直接使用 Node.js 的 fs 模块直接读写 JSON 文件。这样可以避免 ES modules 的问题。
1）electron配置文件
main.js

const { app, BrowserWindow, ipcMain } = require('electron')
const path = require('path')
const fs = require('fs')const STORAGE_PATH = path.join(app.getPath('userData'), 'todos.json')function saveTodos(todos) {fs.writeFileSync(STORAGE_PATH, JSON.stringify(todos))
}function loadTodos() {try {return JSON.parse(fs.readFileSync(STORAGE_PATH, 'utf8'))} catch (error) {return []}
}function createWindow () {const win = new BrowserWindow({width: 800,height: 600,webPreferences: {nodeIntegration: true,contextIsolation: false}})win.loadFile('index.html')
}app.whenReady().then(() => {createWindow()app.on('activate', () => {if (BrowserWindow.getAllWindows().length === 0) {createWindow()}})
})app.on('window-all-closed', () => {if (process.platform !== 'darwin') {app.quit()}
})// 修改这些 IPC 处理器
ipcMain.on('save-todos', (event, todos) => {saveTodos(todos)
})ipcMain.handle('load-todos', () => {return loadTodos()
})

package.json

{"name": "todolist-app","version": "1.0.0","main": "main.js","build": {"appId": "com.yourcompany.todolist","mac": {"category": "public.app-category.productivity"},"win": {"icon": "icons/icon.png","target": ["nsis"]},"linux": {"target": ["AppImage","deb"]}},"scripts": {"start": "electron .","build": "electron-builder  --win"},"keywords": [],"author": "","license": "ISC","description": "","devDependencies": {"electron": "^31.2.1","electron-builder": "^24.13.3"},"dependencies": {}
}

2）网页应用
index.html

<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><meta name="viewport" content="width=device-width, initial-scale=1.0"><title>TodoList</title><link rel="stylesheet" href="styles.css">
</head>
<body><h1>TodoList</h1><form id="todo-form"><input type="text" id="todo-input" placeholder="Enter a new task" required><button type="submit" id="add-button">Add</button></form><ul id="todo-list"></ul><script src="script.js"></script>
</body>
</html>

styles.css

body {font-family: Arial, sans-serif;max-width: 500px;margin: 0 auto;padding: 20px;
}
h1 {text-align: center;
}
#todo-form {display: flex;margin-bottom: 20px;
}
#todo-input {flex-grow: 1;padding: 10px;font-size: 16px;border: 1px solid #ddd;border-radius: 4px 0 0 4px;
}
#add-button {padding: 10px 20px;font-size: 16px;background-color: #4CAF50;color: white;border: none;border-radius: 0 4px 4px 0;cursor: pointer;

#todo-list {list-style-type: none;padding: 0;
}
.todo-item {display: flex;align-items: center;padding: 10px;background-color: #f9f9f9;border: 1px solid #ddd;margin-bottom: 10px;border-radius: 4px;
}
.todo-item.completed {text-decoration: line-through;opacity: 0.6;
}
.todo-item input[type="checkbox"] {margin-right: 10px;
}
.delete-button {margin-left: auto;background-color: #f44336;color: white;border: none;padding: 5px 10px;border-radius: 4px;cursor: pointer;
}

script.js

const { ipcRenderer } = require('electron')const todoForm = document.getElementById('todo-form')
const todoInput = document.getElementById('todo-input')
const todoList = document.getElementById('todo-list')async function loadTodos() {const todos = await ipcRenderer.invoke('load-todos')todos.forEach(todo => {addTodoToDOM(todo.text, todo.completed)})
}function saveTodos() {const todos = Array.from(todoList.children).map(li => ({text: li.querySelector('span').textContent,completed: li.classList.contains('completed')}))ipcRenderer.send('save-todos', todos)
}function addTodoToDOM(text, completed = false) {const li = document.createElement('li')li.className = 'todo-item' + (completed ? ' completed' : '')li.innerHTML = `<input type="checkbox" ${completed ? 'checked' : ''}><span>${text}</span><button class="delete-button">Delete</button>`li.querySelector('input[type="checkbox"]').addEventListener('change', function() {li.classList.toggle('completed')if (li.classList.contains('completed')) {todoList.appendChild(li)} else {todoList.insertBefore(li, todoList.firstChild)}saveTodos()})li.querySelector('.delete-button').addEventListener('click', function() {li.remove()saveTodos()})if (completed) {todoList.appendChild(li)} else {todoList.insertBefore(li, todoList.firstChild)}
}todoForm.addEventListener('submit', function(e) {e.preventDefault()if (todoInput.value.trim() === '') returnaddTodoToDOM(todoInput.value)saveTodos()todoInput.value = ''
})loadTodos()
