如何在Electron

例如,我有一个ReactJS应用程序:https://iaya-664f3.firebaseapp.com/ 您可以在HTML源代码中看到bundle.js文件。

我曾尝试使用Electron将此应用程序作为桌面应用程序运行,它应该在chrome窗口中启动此Web应用程序,但它无法正常工作。

以下是我的主要React应用程序文件app.js,位于根目录中。但编译文件bundle.jsindex.html位于./public/目录中。

./app.js

import React, {Component} from 'react';
import ReactDOM from 'react-dom';
import { Router, Route, browserHistory } from 'react-router';
import routes from './routes';

import {Provider} from "react-redux";
import { createStore, applyMiddleware } from 'redux';
import ReduxPromise from 'redux-promise';
import rootReducer from './reducers/index';

const store = applyMiddleware(ReduxPromise)(createStore)(rootReducer);

ReactDOM.render(  <Provider store={store}>
                    <Router history={browserHistory}  routes={routes} />  
                </Provider> , 

                document.getElementById('react-app'));

./index.js

在这个文件中,我将我的应用程序嵌入到Electron中以运行铬。

var app = require("./app");
var BrowserWindow = require("browser-window");

// on electron has started up , booted up, everything loaded (Chromium ,goen, live)
app.on("ready", function(){
    var mainWindow = new BrowserWindow({
        width:800,
        height:600
    });
    mainWindow.loadUrl("file://" + __dirname+ "/public/index.html");
});

但这会在import React from 'React' ./app.js行中出现错误。

所以我假设,我应该只加载./public/index.html文件来加载包含已编译的bundle.js的文件。但我想知道,这将如何工作,因为app.on("ready", function(){行期望app

此外,我还在 ./index.js 中尝试了以下方式,但它会出现其他一些错误。

const electron = require('electron');

// Module to control application life.
const app = electron.app;

// Module to create native browser window.
const BrowserWindow = electron.BrowserWindow;

const path = require('path');
const url = require('url');

// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is garbage collected.
let mainWindow;

function createWindow () {
    // Create the browser window.
    mainWindow = new BrowserWindow({width: 800, height: 600});

    // and load the index.html of the app.
    /*mainWindow.loadURL(url.format({
        pathname: path.join(__dirname, 'public/index.html'),
        protocol: 'file:',
        slashes: true
    }));*/
    mainWindow.loadURL("file://" + __dirname+ "/public/index.html");

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

    // Emitted when the window is closed.
    mainWindow.on('closed', function () {
        // Dereference the window object, usually you would store windows
        // in an array if your app supports multi windows, this is the time
        // when you should delete the corresponding element.
        mainWindow = null;
    });
}

app.on('ready', createWindow);

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

app.on('activate', function () {
    // On OS X 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 (mainWindow === null) {
        createWindow();
    }
});

基本上事情很简单。电子就像桌面铬包装一样,可以在桌面铬中显示任何(任何)类型的网页。

例如,我们想要显示http://www.google.com,然后您只需将此网址传递给loadURL()功能。

以下是代码的工作副本(在问题中提出):

const electron = require('electron');
  // Module to control application life.
const app = electron.app;
  // Module to create native browser window.
const BrowserWindow = electron.BrowserWindow;

app.on('ready', function(){
    var mainWindow = new BrowserWindow({width: 800, height: 600});

    mainWindow.loadURL("http://localhost:8080/");  // option1: (loading a local app running on a local server)

    //mainWindow.loadURL("https://iaya-664f3.firebaseapp.com");  // option2: (loading external hosted app)

    // loading developer tool for debugging
    mainWindow.webContents.openDevTools();
});

我希望这会澄清许多人的混淆,他们是Electron的新手。所以最后的话是Electron只加载现有的和正在运行的Web应用程序。它不编译,不作为服务器。它只是一个盒子,你可以放置任何东西,并给它一个桌面的外观,例如menues,桌面通知,本地文件系统访问等。
