网站转桌面应用
工具 刘宇帅 5天前 阅读量: 66
这两天工作又比较忙，没看书，没思考，写一篇简单的技术教程。其实我是不想写这种的，因为本身没啥技术含量，只是把写的东西整理一下，即提高不了技术，也没有思考深度，以后要少写，这类还是以笔记的形式记录到博客即可。
最近公司在推jira，但是整体感觉用起来很困难。主要因为是日常浏览器用的会比较多，基本上chrome上都有四五十个tab标签，经常会切到其它tab看东西，然后每次想要找jira的时候都不太好找，所以就想把jira单独打成一个桌面应用，整体操作和心理感受上感觉都简单很多。
electron介绍
Electron是由Github开发，用HTML，CSS和JavaScript来构建跨平台桌面应用程序的一个开源库。 Electron通过将Chromium和Node.js合并到同一个运行时环境中，并将其打包为Mac，Windows和Linux系统下的应用来实现这一目的。
详细教程
新建一个项目并安装electron electron-builder两个依赖
mkdir desktopdemo
cd desktopdemo
cnpm init
cnpm i electron --save-dev
cnpm i electron-builder --save-dev添加构建命令到package.json
"build": {
"appId": "com.example.app",
"mac": {
"target": [
"dmg",
"zip"
]
},
"win": {
"target": [
"nsis",
"zip"
]
}
},
"scripts": {
"start": "electron .",
"dist": "electron-builder"
},新建index.js
(async () => {
const {app, BrowserWindow, BrowserView, ipcMain, webContents} = require("electron");
const {join} = require("path");
await app.whenReady()
const window = new BrowserWindow({
webPreferences: {
sandbox: false,
nodeIntegration: true,
contextIsolation: false
}
});
await window.loadFile(join(__dirname, "./titlebar.html"));
const browserView = new BrowserView({
webPreferences: {
sandbox: true,
nodeIntegration: false
}
});
window.setBrowserView(browserView);
// const contents = window.webContents;
// contents.openDevTools(); //打开调试工具
const contentBounds = window.getContentBounds();
browserView.setBounds({x: 0, y: 50, width: contentBounds.width, height: contentBounds.height - 30});
browserView.setAutoResize({width: true, height: true});
await browserView.webContents.loadURL("https://www.liuyushuai.com/"); // 更换自己的域名
window.webContents.send("sendId", browserView.webContents.id);
window.webContents.on('did-finish-load', function () {
window.webContents.send("sendId", browserView.webContents.id);
})
browserView.webContents.on("did-navigate", () => {
window.webContents.send("canNav", browserView.webContents.canGoBack(), browserView.webContents.canGoForward());
});
ipcMain.on("goBack", (e, webContentsId) => {
const wc = webContents.fromId(webContentsId);
if (wc && wc.canGoBack()) {
wc.goBack();
}
});
ipcMain.on("goForward", (e, webContentsId) => {
const wc = webContents.fromId(webContentsId);
if (wc && wc.canGoForward()) {
wc.goForward();
}
});
})();

新建 renderer.js
const {ipcRenderer} = require("electron");
const backButton = document.getElementById("back");
const forwardButton = document.getElementById("forward");
let webContentsId = -1;
ipcRenderer.on("sendId", (e, id) => {
webContentsId = id;
});
ipcRenderer.on("canNav", (e, canBack, canForward) => {
backButton.disabled = !canBack;
forwardButton.disabled = !canForward;
backButton.classList = canBack ? "button back active":"button back";
forwardButton.classList = canForward?"button next active":"button next";
});
backButton.onclick = () => {
ipcRenderer.send("goBack", webContentsId);
};
forwardButton.onclick = () => {
ipcRenderer.send("goForward", webContentsId);
};
启动
cnpm start
打包
cnpm run dist可以看到dist目录下打包好的包
