# Setup for Upgrading from AngularJS
|
||
|
||
# 准备从 AngularJS 升级
|
||
|
||
<!--
|
||
Question: Can we remove this file and instead direct readers to https://github.com/angular/quickstart/blob/master/README.md
|
||
-->
|
||
|
||
<div class="alert is-critical">
|
||
|
||
**Audience:** Use this guide **only** in the context of [Upgrading from AngularJS](guide/upgrade "Upgrading from AngularJS to Angular") or [Upgrading for Performance](guide/upgrade-performance "Upgrading for Performance").
|
||
Those Upgrade guides refer to this Setup guide for information about using the [deprecated QuickStart GitHub repository](https://github.com/angular/quickstart "Deprecated Angular QuickStart GitHub repository"), which was created prior to the current Angular [CLI](cli "CLI Overview").
|
||
|
||
**注意：**本指南**仅仅**适用于[从 AngularJS 升级](guide/upgrade "Upgrading from AngularJS to Angular")和[注重性能的升级](guide/upgrade-performance "Upgrading for Performance")。
|
||
本指南中提到的升级指南使用的是[已弃用的快速上手 Github 仓库](https://github.com/angular/quickstart "Deprecated Angular QuickStart GitHub repository")，它是在 Angular [CLI](cli "CLI Overview") 推出之前创建的。
|
||
|
||
**For all other scenarios,** see the current instructions in [Local Environment Setup](guide/setup-local "Setting up for Local Development").
|
||
|
||
**对于所有其它场景**，请参见[建立本地开发环境](guide/setup-local "Setting up for Local Development")中的步骤。
|
||
|
||
</div>
|
||
|
||
<!--
|
||
The <live-example name=quickstart>QuickStart live-coding</live-example> example is an Angular _playground_.
|
||
There are also some differences from a local app, to simplify that live-coding experience.
|
||
In particular, the QuickStart live-coding example shows just the AppComponent file; it creates the equivalent of app.module.ts and main.ts internally for the playground only.
|
||
-->
|
||
|
||
This guide describes how to develop locally on your own machine.
|
||
Setting up a new project on your machine is quick and easy with the [QuickStart seed on github](https://github.com/angular/quickstart "Install the github QuickStart repo").
|
||
|
||
本指南讲的是如何在你自己的机器上进行本地化开发。
|
||
利用 [github 上的**《快速上手》种子**](https://github.com/angular/quickstart "安装 github 《快速上手》库")在你的电脑上搭建一个新项目是很快很容易的。
|
||
|
||
**Prerequisite:** Make sure you have [Node.js® and npm installed](guide/setup-local#prerequisites "Angular prerequisites").
|
||
|
||
**前提条件：**确保你已经安装好了 [Node.js® 和 npm](guide/setup-local#prerequisites "Angular prerequisites")。

{@a seed}
|
||
|
||
## What's in the QuickStart seed?
|
||
|
||
## 《快速上手》种子库里都有什么？
|
||
|
||
The **QuickStart seed** provides a basic QuickStart playground application and other files necessary for local development.
|
||
Consequently, there are many files in the project folder on your machine,
|
||
most of which you can [learn about later](guide/file-structure).
|
||
|
||
**《快速上手》种子** 提供了一个基本的《快速上手》游乐场应用，以及进行本地开发的其它必要文件。
|
||
所以，你电脑里的项目目录中有*更多文件*，其中的大部分你都会[在稍后学到](guide/file-structure)。
|
||
|
||
{@a app-files}
|
||
|
||
Focus on the following three TypeScript (`.ts`) files in the **`/src`** folder.
|
||
|
||
注意**`/src`**目录中以下三个 TypeScript (`.ts`) 文件：
|
||
|
||
<div class='filetree'>
|
||
|
||
<div class='file'>
|
||
|
||
src
|
||
|
||
</div>
|
||
|
||
<div class='children'>
|
||
|
||
<div class='file'>
|
||
|
||
app
|
||
|
||
</div>
|
||
|
||
<div class='children'>
|
||
|
||
<div class='file'>
|
||
|
||
app.component.ts
|
||
|
||
</div>
|
||
|
||
<div class='file'>
|
||
|
||
app.module.ts
|
||
|
||
</div>
|
||
|
||
</div>
|
||
|
||
<div class='file'>
|
||
|
||
main.ts
|
||
|
||
</div>
|
||
|
||
</div>
|
||
|
||
</div>
|
||
|
||
<code-tabs>
|
||
|
||
<code-pane header="src/app/app.component.ts" path="setup/src/app/app.component.ts">
|
||
|
||
</code-pane>
|
||
|

<code-pane header="src/app/app.module.ts" path="setup/src/app/app.module.ts">
|
||
|

</code-pane>
|
||
|
||
<code-pane header="src/main.ts" path="setup/src/main.ts">
|
||
|
||
</code-pane>
|
||
|
||
</code-tabs>
|
||
|
||
All guides and cookbooks have _at least these core files_.
|
||
Each file has a distinct purpose and evolves independently as the application grows.
|
||
|
||
所有指南和烹饪书都至少有*这几个核心文件*。每个文件都有独特的用途，并且随着应用的成长各自独立演变。
|
||
|
||
Files outside `src/` concern building, deploying, and testing your app.
|
||
They include configuration files and external dependencies.
|
||
|
||
`src/` 目录之外的文件为构建、部署和测试 app 相关的文件，他们只包括配置文件和外部依赖。
|
||
|
||
Files inside `src/` "belong" to your app.
|
||
Add new Typescript, HTML and CSS files inside the `src/` directory, most of them inside `src/app`,
|
||
unless told to do otherwise.
|
||
|
||
`src/` 目录下的文件才“属于”你的 app。
|
||
除非明确指出，否则教程中添加的 TypeScript，HTML 和 CSS 文件都在 `src/` 目录下，
|
||
大多数在 `src/app` 目录中。
|
||
|
||
The following are all in `src/`
|
||
|
||
`src/` 目录文件详情如下：
|
||
|
||

The JIT compiler is a reasonable choice during the development of most projects and

it's the only viable choice for a sample running in a _live-coding_ environment like Stackblitz.
|

You'll learn about alternative compiling and [deployment](guide/deployment) options later in the documentation.

使[即时 (JIT) 编译器](guide/glossary#jit)用编译应用并且在浏览器中[启动](guide/bootstrapping "启动应用")并运行应用。

|
||
## Appendix: Node.js and npm
|
||
|
||
## 附录：node 与 npm
|
||
|
||
[Node.js](https://nodejs.org/en/) and the [npm](https://www.npmjs.com/) package manager are essential to modern web development with Angular and other platforms.
|
||
Node.js powers client development and build tools.
|
||
The _npm_ package manager, which is itself a _Node.js_ application, installs JavaScript libraries.
|
||
|
||
[Node.js](https://nodejs.org/en/) 和 [npm](https://www.npmjs.com/) 包管理器对使用 Angular 和其他平台进行现代网络开发是至关重要的。
|
||
Node.js 用来支持客户端开发和构建工具。*npm* 包管理器本身就是一个 *Node.js* 应用，用于安装 JavaScript 库。
|
||
|
||
<a href="https://docs.npmjs.com/getting-started/installing-node" target="_blank" title="Installing Node.js and updating npm">Get them now</a> if they're not already installed on your machine.
|
||
|
||
如果你的电脑没有安装它们，请<a href="https://docs.npmjs.com/getting-started/installing-node" target="_blank" title="安装 Node.js 和更新 npm">现在安装</a>。
|
||
|
||
**Verify that you are running Node.js `v8.x` or higher and npm `5.x` or higher**
|
||
by running the commands `node -v` and `npm -v` in a terminal/console window.
|
||
Older versions produce errors.
|
||
|
||
在终端/控制器窗口运行命令 `node -v` 和 `npm -v`，来**确认你运行的 Node.js 是 `v8.x` 或更高，npm 为 `5.x` 或更高。**
|
||
老版本会产生错误。
|
||
|
||
We recommend [nvm](https://github.com/creationix/nvm) for managing multiple versions of Node.js and npm.
|
||
You may need [nvm](https://github.com/creationix/nvm) if you already have projects running on your machine that use other versions of Node.js and npm.
|
||
|
||
我们推荐使用 [nvm](https://github.com/creationix/nvm) 来管理多版本 Node.js 和 npm。
|
||
如果你的电脑上已经有使用其他版本 Node.js 和 npm 的项目，你可能需要 nvm。
|
||
|
||
|
||
## Appendix: Develop locally with IE
|
||
|
||
## 附录：用 IE 进行本地化开发
|
||
|
||
If you develop angular locally with `ng serve`, a `websocket` connection is set up automatically between browser and local dev server, so when your code changes, the browser can automatically refresh.
|
||
|
||
如果你使用 `ng serve` 进行本地化 Angular 开发，就会自动在浏览器和本地开发服务器之间建立一个 `websocket` 连接，这样，在代码发生变化时，浏览器就会自动刷新。
|
||
|
||
In Windows, by default, one application can only have 6 websocket connections, <a href="https://msdn.microsoft.com/library/ee330736%28v=vs.85%29.aspx?f=255&MSPPError=-2147217396#websocket_maxconn" title="MSDN WebSocket settings">MSDN WebSocket Settings</a>.
|
||
So when IE is refreshed (manually or automatically by `ng serve`), sometimes the websocket does not close properly. When websocket connections exceed the limitations, a `SecurityError` will be thrown. This error will not affect the angular application, you can just restart IE to clear this error, or modify the windows registry to update the limitations.
|
||
|
||
在 Windows 上，默认情况下，每个应用最多只能有 6 个 websocket 连接，参见 <a href="https://msdn.microsoft.com/library/ee330736%28v=vs.85%29.aspx?f=255&MSPPError=-2147217396#websocket_maxconn" title="MSDN WebSocket settings">MSDN 上的 WebSocket 设置</a>。
|
||
所以，当 IE 刷新时（手动刷新或由 `ng serve` 自动刷新），websocket 可能无法正常关闭。当 websocket 连接数超过上限时，就会抛出一个 `SecurityError` 异常。这种错误不会影响 Angular 应用，你可以重启 IE 来清除此异常或在 Windows 注册表中加大这个上限。
|
||
|
||
## Appendix: Test using `fakeAsync()/async()`
|
||
|
||
## 附录：使用 `fakeAsync()/async()` 进行测试
|
||
|
||
If you use the `fakeAsync()/async()` helper function to run unit tests (for details, read the [Testing guide](guide/testing#async-test-with-fakeasync)), you need to import `zone.js/dist/zone-testing` in your test setup file.
|
||
|
||
如果你使用 `fakeAsync()/async()` 辅助函数来运行单元测试（详情参见[测试指南](guide/testing#async-test-with-fakeasync)），就要在测试的准备文件中导入 `zone.js/dist/zone-testing`。
|
||
|
||
<div class="alert is-important">
|
||
|
||
If you create project with `Angular/CLI`, it is already imported in `src/test.ts`.
|
||
|
||
如果你是用 `Angular/CLI` 创建的项目，那么它已经在 `src/test.ts` 中导入过了。
|
||
|
||
</div>
|
||
|
||
And in the earlier versions of `Angular`, the following files were imported or added in your html file:
|
||
|
||
在以前版本的 `Angular` 中，下列文件曾被导入或添加到 html 文件中：
|
||
|
||
```
|
||
import 'zone.js/dist/long-stack-trace-zone';
|
||
import 'zone.js/dist/proxy';
|
||
import 'zone.js/dist/sync-test';
|
||
import 'zone.js/dist/jasmine-patch';
|
||
import 'zone.js/dist/async-test';
|
||
import 'zone.js/dist/fake-async-test';
|
||
```
|
||
|
||
You can still load those files separately, but the order is important, you must import `proxy` before `sync-test`, `async-test`, `fake-async-test` and `jasmine-patch`. And you also need to import `sync-test` before `jasmine-patch`, so it is recommended to just import `zone-testing` instead of loading those separated files.
|
||
|
||
你仍然可以分别导入这些文件，不过导入顺序很重要，你必须在 `sync-test`、`async-test`、`fake-async-test` 和 `jasmine-patch` 之前导入 `proxy`。还要注意在 `jasmine-patch` 之前导入`sync-test`。所以，建议你只导入 `zone-testing` 而不要分别加载那些文件。
