Electron: 如何以 Vue.js, Vuetify 开始应用

  • Electron: 使用 JavaScript, HTML 和 CSS 等 Web 手艺建立原生程序的框架
  • Vue.js: Web 前端用于构建用户界面的渐进式框架
  • Vuetify: Vue.js 的 Material Design 组件框架

看完以上先容,也明了了本文要做的事:用 Vue.js 与 Vuetify 组件,基于 Electron 来建立原生桌面应用。

  • 环境准备
    • Visual Studio Code
    • Node.js
    • Yarn
    • Vue CLI
  • 建立 Vue.js 应用
  • 添加 Vuetify 组件
  • 添加 Electron 构建
  • 公布 Electron 应用
  • 参考
  • 结语

环境准备

Visual Studio Code

建议使用的 VS Code 编辑代码,下载地址: https://code.visualstudio.com/

同时可安装如下些扩展:

  • ESLint: 代码检查
  • Prettier – Code formatter: 代码花样化
  • Vetur: Vue 代码工具
  • Vue 2 Snippets: Vue 代码提醒(可选)

查看 VS Code 版本:

$ code -v
1.46.1
cd9ea6488829f560dc949a8b2fb789f3cdc05f5d
x64

Node.js

Node.js 开发环境,下载地址: https://nodejs.org/en/download/

建议选择 Latest LTS Version ,由于 Electron v9 依旧使用的 Node.js v12 。

查看 Node, NPM 版本:

$ node -v
v12.18.1

$ npm -v
6.14.5

Yarn

Yarn 包管理工具,相比 NPM 而言: Fast, Reliable, Secure 。

GitHub: https://github.com/yarnpkg/yarn

全局安装 Yarn :

npm config set registry https://registry.npm.taobao.org
npm install -g yarn

查看 Yarn 版本:

$ yarn -v
1.22.4

Vue CLI

Vue CLI 是 Vue.js 开发的尺度工具。

GitHub: https://github.com/vuejs/vue-cli

全局安装 Vue CLI :

yarn global add @vue/cli

查看 Vue CLI 版本:

$ vue -V
@vue/cli 4.4.6

建立 Vue.js 应用

vue create my-app

追随指导举行工程设置,如下:

Vue CLI v4.4.6
? Please pick a preset: Manually select features
? Check the features needed for your project: Babel, TS, Router, Vuex, Linter
? Use class-style component syntax? Yes
? Use Babel alongside TypeScript (required for modern mode, auto-detected polyfills, transpiling JSX)? Yes
? Use history mode for router? (Requires proper server setup for index fallback in production) Yes
? Pick a linter / formatter config: Prettier
? Pick additional lint features: Lint on save
? Where do you prefer placing config for Babel, ESLint, etc.? In dedicated config files
? Save this as a preset for future projects? No
? Pick the package manager to use when installing dependencies: Yarn

~/.vuerc 会保留一些可复用的 preset :

$ cat ~/.vuerc
{
  "useTaobaoRegistry": true,
  "packageManager": "yarn"
}

运行应用:

cd my-app
yarn serve

浏览器打开 http://localhost:8080/

添加 Vuetify 组件

Vuetify 是 Vue.js 的 Material Design 组件库。也可以换用其他的,如 Element 等。

GitHub: https://github.com/vuetifyjs/vuetify

添加 Vuetify :

cd my-app
vue add vuetify

preset 选择 Default

nginx web服务器概念了解 配置

? Choose a preset: Default (recommended)

添加完成后,编辑下 tsconfig.json

{
  "compilerOptions": {
    ...
    "types": [
-      "webpack-env"
+      "webpack-env",
+      "vuetify"
    ],
    ...
  },
  ...
}

运行应用:

yarn serve

浏览器打开 http://localhost:8080/

编辑 tsconfig.json 是为了修正如下错误

ERROR in /Users/John/Codes/ikuokuo/start-electron/my-app/src/plugins/vuetify.ts(2,21):
2:21 Could not find a declaration file for module 'vuetify/lib'. '/Users/John/Codes/ikuokuo/start-electron/my-app/node_modules/vuetify/lib/index.js' implicitly has an 'any' type.
  Try `npm install @types/vuetify` if it exists or add a new declaration (.d.ts) file containing `declare module 'vuetify/lib';`

      |                     ^

    4 | Vue.use(Vuetify);

添加 Electron 构建

若是你可以建一个网站,你就可以建一个桌面应用程序。 Electron 卖力将 Web 构建成原生桌面应用。

而将 Vue.js 应用构建成 Electron 应用,现在用 Vue CLI Plugin Electron Builder 即可。

首先,指明下 node 版本:

yarn add @types/node@12 --dev

之后,添加 Electron Builder :

cd my-app
vue add electron-builder

Electron 版本选择 9.0.0

? Choose Electron Version ^9.0.0

添加完成后,编辑下 src/router/index.ts

...
const router = new VueRouter({
-  mode: "history",
+  mode: process.env.IS_ELECTRON ? "hash" : "history",
  base: process.env.BASE_URL,
  routes
});

export default router;

运行应用:

yarn electron:serve

现在是桌面窗口了:

Electron: 如何以 Vue.js, Vuetify 开始应用

下令界说在了 package.json

{
  ...
  "scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint",
    "electron:build": "vue-cli-service electron:build",
    "electron:serve": "vue-cli-service electron:serve",
    "postinstall": "electron-builder install-app-deps",
    "postuninstall": "electron-builder install-app-deps"
  },
  ...
}

yarn 执行即可,如下:

$ yarn lint
yarn run v1.22.4
$ vue-cli-service lint
 DONE  No lint errors found!
  Done in 3.17s.

yarn add @types/node@12 --dev 是为了修正如下错误

ERROR in /Users/John/Codes/ikuokuo/start-electron/my-app/node_modules/electron/electron.d.ts(1659,31):
1659:31 Cannot extend an interface 'NodeJS.EventEmitter'. Did you mean 'implements'?
...

编辑 src/router/index.ts 是为了修正如下忠告

 WARN  It is detected that you are using Vue Router. If you are using history mode, you must push the default route when the root component is loaded. Learn more at https://goo.gl/GM1xZG .

公布 Electron 应用

Vue 应用了 Electron Builder 插件,以是直接用此工具即可。

GitHub: https://github.com/electron-userland/electron-builder

yarn electron:build 编译公布:

# 淘宝镜像,海内下载 Electron 更快
export ELECTRON_MIRROR="https://cdn.npm.taobao.org/dist/electron/"

# macOS 下禁用署名。若要署名,见最后参考
export CSC_IDENTITY_AUTO_DISCOVERY=false

cd my-app
yarn electron:build

dist_electron/ 下即是公布内容。

例如 macOS 可见打包好的 dmg

双击 dmg 试用或安装:

若要修改公布花样或内容,见 Electron Builder 文档: https://www.electron.build/

export CSC_IDENTITY_AUTO_DISCOVERY=false 是为了制止如下错误
