4.4.0 Update to vue-cli@4

在新版本中将原来的 vue-cli@3 升级为 vue-cli@4。
主要是为了解决：

• npm run dev 会自动开两个 tab #2944
• npm run build:prod 页面白屏的问题 #3271

vue-cli 升级也非常简单，基本无需自己操作说明， 可参照 https://cli.vuejs.org/migrating-from-v3/

1. 安装 最新版本@vue/cli

npm install -g @vue/cli
# OR
yarn global add @vue/cli

2. 然后执行

vue upgrade

脚本就会自动帮你进行升级

⚠️ Breaking Changes

有一点需要额外注意，在新版本中废弃了通过VUE_CLI_BABEL_TRANSPILE_MODULES来控制懒加载

废弃原因

在vue-cli@3时代，使用VUE_CLI_BABEL_TRANSPILE_MODULES是 ok 的，但其实也是脆弱的，就比如在vue-cli@4时，vue-cli 引入babel-plugin-dynamic-import-node的逻辑就发生了变化，需要VUE_CLI_BABEL_TRANSPILE_MODULES和VUE_CLI_BABEL_TARGET_NODE同时为 true 时才会生效，所以只要 vue-cli 的判断逻辑发生了变化，我们都需要做相对应的改动，或非常被动和耦合。所以我们在vue-cli@4版本中，不再通过VUE_CLI_BABEL_TRANSPILE_MODULES:true来设置，而是通过手动引入'babel-plugin-dynamic-import-node'的方式，具体见下一部分。

vue-cli@4

1. 在 .env.development文件中不在需要配置VUE_CLI_BABEL_TRANSPILE_MODULES = true，删除即可。

2. 在命令行执行 npm install babel-plugin-dynamic-import-node -S -D

3. 在babel.config.js 中添加插件

module.exports = {
  presets: ['@vue/cli-plugin-babel/preset'],
  env: {
    development: {
      plugins: ['dynamic-import-node']
    }
  }
}

具体 commit：2ea998f

---

Upgrade the original vue-cli @ 3 to vue-cli @ 4 in the new version.
Mainly to solve:

-npm run dev will automatically open two tags #2944 -npm run build: white screen issue on prod page #3271

The upgrade of vue-cli is also very simple, basically you don’t need to operate your own instructions, you can refer to https://cli.vuejs.org/migrating-from-v3/

1. Install the latest version @vue/cli

npm install -g @vue/cli
# OR
yarn global add @vue/cli

2. Then execute

vue upgrade

The script will automatically upgrade for you

⚠️ Breaking Changes

One thing needs extra attention. In the new version, the control of lazy loading via VUE_CLI_BABEL_TRANSPILE_MODULES is abandoned.

Elimination reason

In the era of vue-cli@3, using VUE_CLI_BABEL_TRANSPILE_MODULES is ok, but it is actually fragile, as in vue-cli@4, vue-cli introduces babel-plugin-dynamic-import-node The logic ofhas changed, it needs to be VUE_CLI_BABEL_TRANSPILE_MODULES and VUE_CLI_BABEL_TARGET_NODE to be true at the same time, so as long as the judgment logic of vue-cli changes, we need to make corresponding changes, or be very passive and coupled . So in the vue-cli@4 version, we no longer set it by VUE_CLI_BABEL_TRANSPILE_MODULES: true, but by manually introducing 'babel-plugin-dynamic-import-node', see the next section for details.

vue-cli@4

1. No need to configure VUE_CLI_BABEL_TRANSPILE_MODULES = true in the .env.development file, just delete it.

2. Run npm install babel-plugin-dynamic-import-node -S -D

3. The way to add the dynamic-import-node plugin in babel.config.js, see the next section for details.

module.exports = {
  presets: ['@vue/cli-plugin-babel/preset'],
  env: {
    development: {
      plugins: ['dynamic-import-node']
    }
  }
}

v4.3.0 Change Node Sass to Dart Sass

⚠️ Breaking Changes

chore: change node-sass to dart-sass(#3040 by @Cat7373 )

/deep/ 已不适用，需要使用 ::v-deep进行替换

在 v4.3.0之前本项目都是基于node-sass进行构建的，但node-sass底层依赖 libsass，导致很多用户安装的特别的困难，尤其是 windows 用户，它强制用户在windows环境中必须安装python2和Visual Studio才能编译成功。

所以为了解决这个问题，本项目在 v4.3.0修改为dart-sass进行构建，它能在保证性能的前提下大大简化用户的安装成本。通过这个 issue下面相关的评论就可以知道，安装 node-sass 是多么麻烦的一件事。

这里选择使用dart-sass还有一个更主要的原因，sass官方已经将dart-sass作为未来主要的的开发方向了，有任何新功能它都是会优先支持的，而且它已经在社区里稳定运行了很长的一段时间，基本没有什么坑了。dart-sass之所以容易安装，主要是因为它会被编译成纯 js，这样就可以直接在的 node 环境中使用。虽然这样它的运行速度会比基于 libsass的慢一些些，但这些速度的差异几乎可以忽略不计。整个社区现在都在拥抱dart-sass，我们没有理由拒绝！而且它的确大大简化了用户的安装成本。

目前vue-cli在选择sass预处理的时候也会默认优先使用dart-scss，相关 pr

相关的说明可以见该篇文章： Announcing Dart Sass

具体 dart-sass性能评测可见：Perf Report

升级方案

升级也非常的简单，只需要两个步骤

npm uninstall node-sass

npm install sass -S -D

具体可见该： Pull Request

不兼容

替换 node-sass 之后有一个地方需要注意，就是它不再支持之前 sass 的那种 /deep/ 写法，需要统一改为 ::v-deep 的写法。相关： issue

具体 demo：

.a {
  /deep/ {
    .b {
      color: red;
    }
  }
}

/* 修改为 */
.a {
  ::v-deep {
    .b {
      color: red;
    }
  }
}

不管你是否使用dart-sass，我都是建议你使用::v-deep的写法，它不仅兼容了 css 的>>>写法，还兼容了 sass /deep/的写法。而且它还是 vue 3.0 RFC 中指定的写法。

而且原本 /deep/ 的写法也本身就被 Chrome 所废弃，你现在经常能在控制台中发现 Chrome 提示你不要使用/deep/的警告。

⚠️ Breaking Changes

chore: change node-sass to dart-sass(#3040 by @Cat7373 )

/deep/ is no longer applicable, it needs to be replaced with ::v-deep

Before v4.3.0, this project was built based on node-sass, but node-sass low-level dependencies libsass, resulting in many users installing Especially difficult for Windows users, it forces users to install python2 and Visual Studio in the windows environment to compile successfully.

So in order to solve this problem, this project was modified to build dart-sass in v4.3.0, it can guarantee performance Under the premise of greatly simplifying the user's installation costs. Through this issue the relevant comments below can be known, install` Node-sass is such a troublesome thing.

There is a more important reason for choosing to use dart-sass here. Officially, sass has taken dart-sass as the main development direction in the future. Any new features will be supported first, and it It has been running steadily in the community for a long time, and there are basically no pits. The main reason why dart-sass is easy to install is because it will be compiled into pure js, so that it can be used directly in the node environment. Although its running speed will be slower than that based on libsass, the difference in these speeds is almost negligible. The entire community is now embracing dart-sass, and we have no reason to refuse! And it does greatly simplify the user's installation costs.

Currently, vue-cli will also prefer to use dart-scss by default when selecting sass preprocessing, related: pr

Related instructions can be found in this article: Announcing Dart Sass

Specific dart-sass performance evaluation can be seen: Perf Report

Upgrade plan

The upgrade is also very simple, requiring only two steps

npm uninstall node-sass

npm install sass -S -D

The upgrade can also be seen in detail: Pull Request is simple and only requires two steps

Not compatible

One thing to note after replacing node-sass is that it no longer supports the /deep/ writing style of sass before, and it needs to be changed to the writing style of ::v-deep. Related: issue

Concrete demo:

.a {
  /deep/ {
    .b {
      color: red;
    }
  }
}

/* change into */
.a {
  ::v-deep {
    .b {
      color: red;
    }
  }
}

Regardless of whether you use dart-sass or not, I suggest you use ::v-deep notation, which is not only compatible with the css >>> notation, but also compatible with sass /deep/ . And it's the way of writing specified in vue 3.0 RFC.

And the original writing of /deep/ itself was abandoned by Chrome. You can often find a warning in the console that Chrome reminds you not to use /deep/.

v4.0.0

v4.0版本正式发布。

重大改变

• 基于 vue-cli@3进行构建

• 调整了项目的目录结构

  • mock 文件移至根目录下
  • layout 从 views 文件夹下移至 src 下

• 使用了最新的 eslint-plugin-vue@5，重新格式化了代码

• 现在可以在不刷新页面的情况下 remove routes

• 更新了[email protected]

• 增加了 jest 单元测试

• 新增了 npm run preview、 npm run test:uni、 npm run new指令

• 使用了新的 mock 方式，解决了之前 mock 若干问题

• vuex 启用了 模块化 namespaced

• 新增了 settings.js，让 sidebarLogo、fixedHeader、TagsViews 等都可配置

• 新增了 sidebar logo

• 重构了侧边栏 sidebar 代码逻辑，并且优化了样式和展开收起动画，同时让二级菜单内容过多时支持滚动

• 使用了 async/await 替代了部分 promise 代码

• 增加了 header-search 组件 #1591

• 增加了 fearure[TagsView]: add affix porperty #1577

• 移除了 tree-table 组件。 element-ui v2.7.0 开始支持tree-table，所以不再独立维护。

• 增加了权限配置 demo

• 增加了导出多级表头 excel 的 demo

• feature[Directive]: add auto-height table directive

RoadMap

• 更好的多级页面的缓存：目前页面的缓存基于keep-alive，但当三级路由嵌套的情况下，支持的并不好。之后探索一个更好的解决方案。
• 单元测试：当项目大了之后，没有单元测试维护起来还是有些吃力的。
  之后会慢慢补上 unit-test 的测试用例。 酌情加上一些e2e-test的例子。
• 去国际化：其实大部分人是不需要国际化的，默认情况下移除国际化。单独开一个国际化分支。
• 适配 webpack5：webpack5 还是解决了不少之前的痛点的，正式版发布之后会进行升级
• vue 3.0： 等官方发布之后会基于新版本进行重构

---

The v4.0 version was officially released.

Breaking Changes

• Build based on vue-cli@3

• Adjusted the directory structure

  • Mock file move to root directory
  • Layout from the views folder to src

• Reformatted the code with the latest eslint-plugin-vue@5

• You can now remove routes without refreshing the page.

• Updated [email protected]

• Added jest unit test

• Added npm run preview, npm run test:uni, npm run new directive

• Using the new mock method, solved some problems with the previous mock

• vuex use namespaced

• Added settings.js to make sidebarLogo, fixedHeader, TagsViews, etc. configurable

• Add sidebar logo

• Refactored the sidebar code logic and optimized the style and unfolding the animation

• Use Async/await

• Add header-search #1591

• Add fearure[TagsView]: add affix porperty #1577

• Remove tree-table. element-ui v2.7.0 started to support tree-table, so it is no longer maintained independently.

• Added permission configuration demohttps://github.com/PanJiaChen/vue-element-admin/commit/c963f56686b9731a517a17c4d562bc3da0fa3771

• Added demo to export multi-level header excel

• feature[Directive]: add auto-height table directive #1702 (by @yuntao1997 )

RoadMap

• Better multi-level page caching: The current page cache is based on keep-alive, but when the three-level routing is nested, the support is not good. Then explore a better solution.
• Unit testing: When the project is big, it is still a little difficult to maintain without unit testing.
  The unit-test test case will be added slowly. Add some examples of e2e-test as appropriate.
• Remove i18n: In fact, most people do not need to be i18n. Open a i18n branch separately.
• Adapting webpack5: webpack5 still solves a lot of pain points before, the upgrade will be upgraded after the official version is released.
• vue 3.0： vue 3.0: Refactoring based on the new version after official release

v3.11.0

注意：这是 v4.0 版本之前最后的一个版本更新了。之后除非有重大bug，不然 v3.x.x版本将不再继续迭代。

Note: This is the last version update before the v4.0 version. After that, unless there is a major bug, the v3.x.x version will not continue to iterate.
