uniapp或者vue 使用serialport

参考https://blog.csdn.net/ykee126/article/details/90440499

版本是第一位：否则容易编译失败
node 版本 18.14.0
npm 版本 9.3.1
electron 版本 30.0.8
electron-rebuild 版本 3.2.9
serialport 版本 10.0.0

需要python环境

在这里插入图片描述

main.js

// Modules to control application life and create native browser window
const { app, BrowserWindow, Menu } = require('electron')
const path = require('path')

function createWindow () {
  // Create the browser window.
  const mainWindow = new BrowserWindow({
    width: 1920,
    height: 1080,
    webPreferences: {
	  nodeIntegration: true, //设置开启nodejs环境
	  contextIsolation: false,
      preload: path.join(__dirname, 'preload.js')
    }
  })

  // and load the index.html of the app.
  mainWindow.loadFile('./dist/index.html')

  // Open the DevTools.
  mainWindow.webContents.openDevTools()
}

// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.whenReady().then(() => {
  createWindow()

  app.on('activate', function () {
    // On macOS it's common to re-create a window in the app when the
    // dock icon is clicked and there are no other windows open.
    if (BrowserWindow.getAllWindows().length === 0) createWindow()
  })
})

// Quit when all windows are closed, except on macOS. There, it's common
// for applications and their menu bar to stay active until the user quits
// explicitly with Cmd + Q.
app.on('window-all-closed', function () {
  if (process.platform !== 'darwin') app.quit()
})

Menu.setApplicationMenu(null);

// In this file you can include the rest of your app's specific main process
// code. You can also put them in separate files and require them here.

直接

npm install

然后编译serialport

.\node_modules\.bin\electron-rebuild.cmd

期间会遇到各种问题
需要python环境

serialport-util.js

const {
	SerialPort
} = require("serialport");
export default {
	init() {
		const port = new SerialPort({
			path: 'COM3',
			baudRate: 115200,
			dataBits: 8,
			parity: 'none',
			stopBits: 1,
			flowControl: false,
		});

		port.on('data', (data) => {
			console.log('Data received:', data);
			// 在这里处理接收到的数据，或者通过IPC发送给渲染进程
		});
		port.on('error', (err) => {
			console.error('Error with serial port:', err);
		});
	}
}
