"content": "# AVVW APICLOUD 开发框架\n\nApicloud + Vue2 + Vant2（有赞前端）+ Webpack4 (Vue-cli3) 打包，是一个采用 Vue 数据绑定特性和 Apicloud 手机操控能力相结合的 APP 开发框架，此框架**并非**采用 Vue 的 SPA 单页面应用方式，而是遵从 Apicloud 的多页面原生渲染效率方式，Vue+Webpack 只是为了提供更佳的 ES2015+语法、模块分割和数据绑定代码体验，弥补 Apicloud 本身无法应用在庞大工程协作的缺点。\n\n> 使用 AVVW 可以极速开发出流畅的商用级别 APP，让你轻松应付各种开发需求\n\n> 采用最新 Vue-cli3 脚手架制作，开发、编译和维护更轻便快捷\n\n# 案例展示\n\n [知法乎](https://apps.apple.com/cn/app/id1454196247)\n\n\n\n---\n\n [广州电台花城 FM](http://hcfm.gztv.com)\n\n\n\n---\n\n [俭道](https://apps.apple.com/cn/app/俭道/id1517346440)\n\n\n\n---\n\n [易挖网](https://apps.apple.com/cn/app/易挖网/id1476913825)\n\n\n\n---\n\n [建老大](https://apps.apple.com/cn/app/建老大/id1504655165#?platform=iphone)\n\n\n\n---\n\n [武文浓墨](https://apps.apple.com/cn/app/id1504004849)\n\n\n\n---\n\n [收货地址助手](https://apps.apple.com/cn/app/id1510714935)\n\n\n\n# 目录结构\n\n- dist 编译代码，压缩后上传到 Apicloud 发布 App\n- src 源代码，所有开发在此开始，除 pages 目录外，其他目录可随意增删\n - components Vue 公用组件\n - libs 公共库\n - **pages** Apicloud 使用 openWin 和 openFrame 打开的页面，vue 组件化，支持**多级目录**\n- public Webpack 编译时的模板文件，**不能随意修改，除非您知道自己在干什么**\n - js/fastclick.min.js 移动端减少触点反馈时间\n - js/vue.js 未压缩 vue 库，用于开发环境\n - js/vue.min.js 压缩 vue 库，用于生产环境\n - index.html Apicloud 启动文件\n - page.ejs 将 pages 下 vue 编译为 Apicloud 可用的模板\n - config.xml Apicloud 配置文件\n- .env 开发和生成环境对应的入口地址\n- 其他省略\n\n# 开始使用\n\ngit clone 或者 直接下载 master 包，cd 进入包目录后安装依赖\n\n```bash\nnpm i # 初始化安装npm模块\n```\n\n### 手机实时调试\n\n```bash\nnpm run wifi-start # 开wifi服务，Apploader连接wifi服务，wifi-stop 停止服务\n```\n\n待 wifi 服务开启后，查看本地 ip 地址，如下地址：\n\n```bash\nAPICloud Is Listening on ip: [\"192.168.0.104\",\"192.168.146.1\",\"192.168.69.1\"]\n```\n\n然后打开./.env，修改 VUE_APP_ENTRY_DEV 测试环境下调试手机能访问你本地测试服的局域网 IP:8080，如下：\n\n```text\nVUE_APP_ENTRY_DEV=http://192.168.0.104:8080/home.html\nVUE_APP_ENTRY_PRD=./home.html\n```\n\n然后再打开本地测试服\n\n```bash\nnpm run dev # 开启本地测试服\n```\n\n> **特别注意：如果你在开发时增加了./src/pages/里的页面，那么需要先关闭 dev，重新运行才会编译新页面，因为多入口热加载并不会检测新页面**\n\n待本地测试服开启后，可以开始同步文件到手机 Apploader 进行调试\n\n```bash\n npm run wifi-sync # 真机wifi同步\n npm run wifi-log # 真机wifi日志输出\n```\n\n> 注意：wifi-sync 和 wifi-log 都只需要运行一次，Apploader 第一次同步完成后，修改./src 文件保存后手机自动同步和浏览器热加载一样！无需再手动 wifi-sync 同步一次！\n\n> **特别注意：很多小伙伴发现开发时页面第一次加载比较慢，其实是因为手机从本地局域网电脑无线获取页面数据而导致的，但编译为发布包时，页面文件会一并打入 APP，所以开发时的页面加载速度可忽略！**\n\n### config.xml\n\n使用自定义 Apploader 时，./public/config.xml 的 `` 的 widget id 必须修改为您的 App id 才能 Wifi 同步成功\n\n### 本地浏览器调试\n\n```bash\nnpm run dev # 开启本地测试服\n```\n\n打开浏览器输入例如 http://localhost:8080/home.html 即可对某个页面进行调试，注意由于在本地浏览器环境下，所以无法调试 Apicloud sdk 的相关功能\n\n### 编译上传\n\n```bash\n npm run build # 编译\n```\n\n编译后，修改./dist 目录名称为 ./widget，压缩./widget 文件夹生成 widget.zip 上传 apicloud 后台的“代码”处即可进行发布\n\n# 如何升级\n\n从 v1.3.0 之前的版本升级，只需获取框架最新源代码后，将旧项目的./src 下除 templates 外的文件全部覆盖到 v1.3.0 框架下的./src 下，然后对比修改 package.json，同时对比修改 public/index.html 和 page.ejs 后，重新运行 npm i 安装新开发依赖即可！\n\n# 开发细节\n\n如无需高级配置，那么只需关注 src 目录下文件，这里说明一下 pages 文件：\n\n### xxx.vue\n\n任何 vue 语法都可以使用，而且直接`export default`vue 即可，**无需再像 v1.3.0 之前版本那样 window.xxxVue 这样处理**\n\n> 由于框架并非采用 Vue 的 SPA，所以无法在多页面间使用 vue-router、vuex 之类的单页面应用的数据共享技术，而只能采用 Apicloud API 提供的相关页面跳转传递、数据共享技术\n\n### 多级目录引用\n\nApicloud 引用打开多级目录页面时，以./src/pages 作为根目录如下调用:\n\n```js\nthis.$ac.openFrameGroup({\n name: \"homeTabs\",\n frames: [\n {\n name: \"tab1\",\n url: \"./tabs-tab1.html\", // 引用多级目录文件格式: ./[subdir]-[...]-[filename].html\n },\n {\n name: \"tab2\",\n url: \"./tabs-tab2.html\",\n bounces: true,\n },\n {\n name: \"tab3\",\n url: \"./tabs-tab3.html\",\n },\n ],\n});\n```\n\n### 首页入口\n\n框架默认 home.html 为 App 首页入口，你也可以修改其他页面为入口，只需修改./.env\n\n```text\nVUE_APP_ENTRY_DEV=http://192.168.0.104:8080/home.html # 修改home.html为main.html, eg.\nVUE_APP_ENTRY_PRD=./home.html # 修改home.html为main.html, eg.\n```\n\n### 本地浏览器预览\n\nnpm run dev 开启测试服，但和一般的 vue 测试不同的是，你需要手动切换需要测试的页面，eg. [http://localhost:8080/home.html](http://localhost:8080/home.html)，不能测试 index.html，因为此文件是 Apicloud 所用，页面测试时遇到**api is not defined**不用理会，因为 api 是 Apicloud App 环境下才初始化的对象\n\n> 浏览器预览是用来调节界面排版布局，体验性测试请使用真机 Apploader\n\n### Apicloud API SDK\n\n你可以在 vue 中直接使用 api.xxx，也可以使用 this.\\$ac.xxx 来调用 api sdk\n\n### ES6 支持\n\n> vue 支持大部分 ES6 语法，但要注意的是如果你修改 public 下的 page.ejs 和 index.html，请不要使用 ES6 语法，因为 webpack 默认没有转义模板文件\n\n### 按需加载和异步加载\n\n> 手机 CPU 和内存有限，而且 Apicloud 采用 Hybird 技术，在性能上尤其低端安卓上肯定大打折扣，所以使用按需加载、异步加载和懒加载会更好地让 App 保持流畅原生感\n\n### 开发编译内存溢出\n\n有小伙伴在开发时发现页面过多时，热加载编译会出现内存溢出问题，已修改 npm run dev 的脚本命令增加 node 的运行时内存上限，如仍出现内存溢出，请继续上调 max_old_space_size 的值\n\npackage.json:\n\n```json\n\"scripts\" {\n \"dev\": \"cross-env NODE_OPTIONS=--max_old_space_size=8192 vue-cli-service serve\"\n}\n```\n\n# 扩展使用\n\n框架集成了[有赞 vant](https://vant-contrib.gitee.io/vant) 2.8.4 前端框架，适用大部分需求，当然你也可以更换其他 Vue 前端框架。\n\n> 欢迎扩展和完善此框架，接下去我会放出更多其他更好用的开发框架\n\n---\n\n_Copyright by [Grape Studio](https://github.com/grapewheel?tab=repositories)_ \n_QQ 群 492968709_\n"
