Detect webpage updates and notify user to reload. support vite, umijs and webpack.

> Take the git commit hash (also support svn revision number、package.json version、build timestamp、custom) as the version number, and write version into json file. The client polls the version of the server (visibilitychange or focus event assistant), compares it with the local one, and if it is not the same, notifies the user to refresh the page (you can custom behavior).

**When to check for updates (fetch version.json)** ?

1. first load page.
2. poll (default: 10 * 60 * 1000 ms).
3. script resource loading failure detected (404 ?).
4. when the tab page is refocus or revisible.

## Why

Some users do not have the habit of closing web pages. If the front-end page is updated, the user page has always been a historical version, any there may be report an error (file 404) or a white screen.

## Install

```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
```

## Usage

[vite](#vite) | [umi](#umijs) | [webpack](#webpack)

### Vite

**basic usage**

```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,
    }),
  ]
})
```

**custom notification text**

```ts
// vite.config.ts
export default defineConfig({
  plugins: [
    vue(),
    webUpdateNotice({
      notificationProps: {
        title: 'system update',
        description: 'System update, please refresh the page',
        buttonText: 'refresh',
      },
    }),
  ]
})
```

**internationalization**

```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')
```

**hidden default notification, listener to update event and custom behavior.**

```ts
// vite.config.ts
export default defineConfig({
  plugins: [
    vue(),
    webUpdateNotice({
      hiddenDefaultNotification: true
    }),
  ]
})

// other file to listener update event and custom behavior
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

```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,
      }),
    ],
  },
})
```

### suggest: disabled index.html cache

```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;
}
```

## What was changed

![inject_content](https://raw.githubusercontent.com/GreatAuk/plugin-web-update-notification/master/images/inject_content.webp)

## Q&A

1. `TypeScript` intellisense, if you use `window.pluginWebUpdateNotice_.` or listener custom update event。

   ```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. request `version.json` file get `404 error`.

   If you upload the production files bundled to cdn server:

   ```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
       })
     ]
   })
   ```

   Deploy the project in a non-root directory:

   ```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, in most case, you not need to set injectFileBase, it will be automatically detected from the base of vite config、publicPath of webpack config or publicPath of umi config

3. Custom notification button event.

   ```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. Custom notification style.

   you can cover css styles with higher weights. ([default css file](https://github.com/GreatAuk/plugin-web-update-notification/blob/master/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. manual check update.

   ```ts
   // vue-router check update before each route change
   router.beforeEach((to, from, next) => {
     window.pluginWebUpdateNotice_.checkUpdate()
     next()
   })
   ```

6. Some versions do not notify. For example, if the customer version is `v1.0`, you need to update to `v1.0.1`, but do not want to display the update prompt.

   ```ts
   webUpdateNotice({
     ...
     silence: true
   })
   ```
