QuickStart Rewrite (2016-11-18)

全新《快速起步》 (2016-11-18)

The QuickStart is completely rewritten so that it actually is quick. It references a minimal "Hello Angular" app running in Plunker. The new Setup page tells you how to install a local development environment by downloading (or cloning) the QuickStart github repository. You are no longer asked to copy-and-paste code into setup files that were not explained anyway.

《快速起步》被重新编写,变得更加快速。 它使用了在 Plunker 中运行的最小化的 “Hello Angular” 应用。 新添加的搭建本地开发环境页面解释了如何通过下载或者克隆 QuickStart github 库来安装本地开发环境。 你将不再需要拷贝粘贴代码到一些并没有对其解释的配置文件中。

npm @types packages replace typings (2016-10-20)

使用npm的@types包替换typings (2016-10-20)

Documentation samples now get TypeScript type information for 3rd party libraries from npm @types packages rather than with the typings tooling. The typings.json file is gone.

文档例子现在从npm的@types第三方库获取TypeScript类型信息,不再使用typings。 删除typings.json文件。

The "Angular 1 Upgrade" guide reflects this change. The package.json installs @types/angular and several @types/angular-... packages in support of upgrade; these are not needed for pure Angular 2 development.

"从1.x升级"指南反映了这个变化。 package.json安装@types/angular和一些@types/angular-...包来支持升级。它们在纯Angular 2开发中是不需要的。

"Template Syntax" explains two-way data binding syntax (2016-10-20)

展示了如何在自定义Angular组件中双向数据绑定,用基础[()]重新解释[(ngModel)]

BREAKING CHANGE: in-memory-web-api (v.0.1.11) delivered as esm umd (2016-10-19)

破坏性变化:in-memory-web-api (v.0.1.11) 以esm umd的形式发布 (2016-10-19)

This change supports ES6 developers and aligns better with typical Angular libraries. It does not affect the module's API but it does affect how you load and import it. See the change note in the in-memory-web-api repo.

这个变化支持ES6开发者,并与典型的Angular库看齐。 它不会影响模块的API,但是它改变了加载和导入它的方式。 参见in-memory-web-api库的变更记录

"Router" preload syntax and :enter/:leave animations (2016-10-19)

"路由器"预加载语法和:enter/:leave动画(2016-10-19)

The router can lazily preload modules after the app starts and before the user navigates to them for improved perceived performance.

路由器可以在应用启动之后和用户导航到惰性加载模块之前,预先加载惰性模块,以增强性能。

New :enter and :leave aliases make animation more natural.

:enter:leave语法,让动画更加自然。

The Routing and Navigation guide now locates route configuration in a Routing Module. The Routing Module replaces the previous routing object involving the ModuleWithProviders.

Routing and Navigation现在在路由模块中设置路由配置。 路由模块替换之前的路由对象,使用了ModuleWithProviders

Routing and Navigation

路由与导航

All guided samples with routing use the Routing Module and prose content has been updated, most conspicuously in the NgModule guide and NgModule FAQ cookbook.

重命名“angular-in-memory-web-api”包(2016-09-27)

Many samples use the angular-in-memory-web-api to simulate a remote server. This library is also useful to you during early development before you have a server to talk to.

许多例子使用了angular-in-memory-web-api来模拟远程服务器。 这个库在你拥有服务器之前的早期开发阶段也很有用。

The package name was changed from "angular2-in-memory-web-api" which is still frozen-in-time on npm. The new "angular-in-memory-web-api" has new features. Read about them on github.

这个包的名字从“angular2-in-memory-web-api”(仍然有效,但不再更新了)重新命名了。 新的“angular-in-memory-web-api”有新的功能。 到github获得更多详情.

"Style Guide" with NgModules (2016-09-27)

“风格指南”中添加了NgModules(2016-09-27)

StyleGuide explains our recommended conventions for Angular modules (NgModule).

StyleGuide解释了我们为Angular模块(NgModule)而推荐的约定。

Barrels now are far less useful and have been removed from the style guide; they remain valuable but are not a matter of Angular style. We also relaxed the rule that discouraged use of the @Component.host property.

现在,封装桶不再那么重要,风格指南已经移除了它们。 它们仍然很有价值,但是它们与Angular风格无关。 我们同时对不推荐使用@Component.host属性的规则有所放宽。

moduleId: module.id everywhere (2016-09-25)

moduleId:到处添加module.id(2016-09-25)

Sample components that get their templates or styles with templateUrl or styleUrls have been converted to module-relative URLs. We added the moduleId: module.id property-and-value to their @Component metadata.

在所有使用templateUrl或者styleUrls来获取模板或样式的例子组件都被转换为相对模块的URL。 我们添加了moduleId: module.id到它们的@Component元数据。

This change is a requirement for compilation with AoT compiler when the app loads modules with SystemJS as the samples currently do.

当应用像例子当前使用的方法一样 - 使用SystemJS加载模块时,本更新是AoT编译器的前提条件。

"Lifecycle Hooks" guide simplified (2016-09-24)

简化了“生命周期钩子”章(2016-09-24)

The Lifecycle Hooks guide is shorter, simpler, and draws more attention to the order in which Angular calls the hooks.
