检测网页更新并通知用户刷新，支持 vite、umijs 和 webpack 插件。

> 以 git commit hash (也支持 svn revision number、package.json version、build timestamp、custom) 为版本号，打包时将版本号写入 json 文件。客户端轮询服务器上的版本号（浏览器窗口的 visibilitychange、focus 事件辅助），和本地作比较，如果不相同则通知用户刷新页面。

**什么时候会检测更新(fetch version.json)**  ?

1. 首次加载页面。
2. 轮询 （default: 10 * 60 * 1000 ms）。
3. script 脚本资源加载失败 (404 ?)。
4. 标签页 refocus or revisible。

## Why

部分用户（老板）没有关闭网页的习惯，在网页有新版本更新或问题修复时，用户继续使用旧的版本，影响用户体验和后端数据准确性。也有可能会出现报错（文件404）、白屏的情况。

## 安装

```bash
# vite
pnpm add @plugin-web-update-notification/vite -D

# umijs
pnpm add @plugin-web-update-notification/umijs -D

# webpack plugin
pnpm add @plugin-web-update-notification/webpack -D
```

## 快速上手

[vite](#vite) | [umi](#umijs) | [webpack](#webpack)

### 关键：禁用 `index.html` 缓存！！！

如果 `index.html` 存在缓存，可能刷新后，更新提示还会存在，所以需要禁用 `index.html` 的缓存。这也是 `SPA` 应用部署的一个最佳实践吧。

通过 `nginx` ，禁用缓存：

```nginx
# nginx.conf
location / {
  index index.html index.htm;

  if ( $uri = '/index.html' ) { # disabled index.html cache
    add_header Cache-Control "no-cache, no-store, must-revalidate";
  }

  try_files $uri $uri/ /index.html;
}
```

直接通过 `html meta` 标签禁用缓存：

```html
<!DOCTYPE html>
<html lang="en">
<head>

  <meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate" />
  <meta http-equiv="Pragma" content="no-cache" />
  <meta http-equiv="Expires" content="0" />

</head>
</html>
```

### Vite

**基础使用**

```ts
// vite.config.ts
import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import { webUpdateNotice } from '@plugin-web-update-notification/vite'

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [
    vue(),
    webUpdateNotice({
      logVersion: true,
    }),
  ]
})
```

**自定义通知栏文本**

```ts
// vite.config.ts
export default defineConfig({
  plugins: [
    vue(),
    webUpdateNotice({
      notificationProps: {
        title: '标题',
        description: 'System update, please refresh the page',
        buttonText: '刷新',
        dismissButtonText: '忽略'
      },
    }),
  ]
})
```

**国际化**

```ts
// vite.config.ts
export default defineConfig({
  plugins: [
    vue(),
    webUpdateNotice({
      // plugin preset: zh_CN | zh_TW | en_US
      locale: "en_US",
      localeData: {
        en_US: {
          title: "📢 system update",
          description: "System update, please refresh the page",
          buttonText: "refresh",
          dismissButtonText: "dismiss",
        },
        zh_CN: {
          ...
        },
        ...
      },
    }),
  ],
});


// other file to set locale
window.pluginWebUpdateNotice_.setLocale('zh_CN')
```

**取消默认的通知栏，监听更新事件自定义行为**
```ts
// vite.config.ts
export default defineConfig({
  plugins: [
    vue(),
    webUpdateNotice({
      hiddenDefaultNotification: true
    }),
  ]
})

// 在其他文件中监听自定义更新事件
document.body.addEventListener('plugin_web_update_notice', (e) => {
  const { version, options } = e.detail
  // write some code, show your custom notification and etc.
  alert('System update!')
})
```

### Umijs

不支持 `umi2`, `umi2` 可以尝试下通过 `chainWebpack` 配置 `webpack` 插件。

```ts
// .umirc.ts
import { defineConfig } from 'umi'
import type { Options as WebUpdateNotificationOptions } from '@plugin-web-update-notification/umijs'

export default {
  plugins: ['@plugin-web-update-notification/umijs'],
  webUpdateNotification: {
    logVersion: true,
    checkInterval: 0.5 * 60 * 1000,
    notificationProps: {
      title: 'system update',
      description: 'System update, please refresh the page',
      buttonText: 'refresh',
      dismissButtonText: 'dismiss',
    },
  } as WebUpdateNotificationOptions
}
```

### webpack

```js
// vue.config.js(vue-cli project)
const { WebUpdateNotificationPlugin } = require('@plugin-web-update-notification/webpack')
const { defineConfig } = require('@vue/cli-service')

module.exports = defineConfig({
  // ...other config
  configureWebpack: {
    plugins: [
      new WebUpdateNotificationPlugin({
        logVersion: true,
      }),
    ],
  },
})
```

## webUpdateNotice Options

```ts
function webUpdateNotice(options?: Options): Plugin

## 变动了哪些内容

![inject_content](https://raw.githubusercontent.com/GreatAuk/plugin-web-update-notification/main/images/inject_content.webp)

## Q&A

1. `TypeScript` 的智能提示, 如果你想使用 `window.pluginWebUpdateNotice_.` 或监听自定义更新事件。

   ```ts
   // src/shim.d.ts

   // if you use vite plugin
   /// <reference types="@plugin-web-update-notification/vite" />

   // if you use umi plugin
   /// <reference types="@plugin-web-update-notification/umijs" />

   // if you use webpack plugin
   /// <reference types="@plugin-web-update-notification/webpack" />
   ```

2. 请求 `version.json` 文件提示 `404 error`。

   上传打包内容到 cdn 服务器：

   ```ts
   // vite.config.ts

   const prod = process.env.NODE_ENV === 'production'

   const cdnServerUrl = 'https://foo.com/'

   export default defineConfig({
     base: prod ? cdnServerUrl : '/',
     plugins: [
       vue(),
       webUpdateNotice({
         injectFileBase: cdnServerUrl
       })
     ]
   })
   ```

   在非根目录下部署的项目：

   ```ts
   // vite.config.ts

   const prod = process.env.NODE_ENV === 'production'

   const base = '/folder/' // https://example.com/folder/

   export default defineConfig({
     base,
     plugins: [
       vue(),
       webUpdateNotice({
         injectFileBase: base
       })
     ]
   })
   ```

   > After version 1.2.0, you not need to set this option, it will be automatically detected from the base of vite config、publicPath of webpack config or publicPath of umi config

3. 自定义 `notification` 的刷新和忽略按钮事件。

   ```ts
   // refresh button click event, if you set it, it will cover the default event (location.reload())
   window.pluginWebUpdateNotice_.onClickRefresh = (version) => { alert(`click refresh btn: ${version}`) }

   // dismiss button click event, if you set it, it will cover the default event (dismissUpdate())
   window.pluginWebUpdateNotice_.onClickDismiss = (version) => { alert(`click dismiss btn: ${version}`) }
   ```

4. 自定义 notification 样式。

   你可以通过更高的权重覆盖默认样式。([default css file](https://github.com/GreatAuk/plugin-web-update-notification/blob/main/packages/core/public/webUpdateNoticeInjectStyle.css))

   ```html
   <!-- notification html content -->

   <div class="plugin-web-update-notice-anchor">
     <div class="plugin-web-update-notice">
       <div class="plugin-web-update-notice-content" data-cy="notification-content">
         <div class="plugin-web-update-notice-content-title">
           📢  system update
         </div>
         <div class="plugin-web-update-notice-content-desc">
           System update, please refresh the page
         </div>
         <div class="plugin-web-update-notice-tools">
           <a class="plugin-web-update-notice-btn plugin-web-update-notice-dismiss-btn">dismiss</a>
           <a class="plugin-web-update-notice-btn plugin-web-update-notice-refresh-btn">
             refresh
           </a>
         </div>
       </div>
     </div>
   </div>
   ```

5. 手动检测更新

   ```ts
   // vue-router check update before each route change
   router.beforeEach((to, from, next) => {
     window.pluginWebUpdateNotice_.checkUpdate()
     next()
   })
   ```

6. 部分版本不通知。如客户版本是 `v1.0`, 你需要更新 `v1.0.1`, 但不想显示更新提示。

   ```ts
   webUpdateNotice({
     ...
     silence: true
   })
   ```
