| # Change Log
 | |
| 
 | |
| 
 | |
| 
 | |
| The Angular documentation is a living document with continuous improvements.
 | |
| This log calls attention to recent significant changes.
 | |
| 
 | |
| ## Updated to Angular 4.0. Documentation for Angular 2.x can be found at [v2.angular.io](https://v2.angular.io).
 | |
| 
 | |
| ## All mention of moduleId removed. "Component relative paths" guide deleted (2017-03-13)
 | |
| We added a new SystemJS plugin (systemjs-angular-loader.js) to our recommended SystemJS configuration.
 | |
| This plugin dynamically converts "component-relative" paths in templateUrl and styleUrls to "absolute paths" for you.
 | |
| 
 | |
| We strongly encourage you to only write component-relative paths.
 | |
| That is the only form of URL discussed in these docs. You no longer need to write @Component({ moduleId: module.id }), nor should you.
 | |
| 
 | |
| ## NEW: Downloadable examples for each guide (2017-02-28)
 | |
| Now you can download the sample code for any guide and run it locally.
 | |
| Look for the new download links next to the "live example" links.
 | |
| 
 | |
| ## Template Syntax/Structural Directives: refreshed (2017-02-06)
 | |
| The [_Template-Syntax_](guide/template-syntax) and [_Structural Directives_](guide/structural-directives)
 | |
| guides were significantly revised for clarity, accuracy, and current recommended practices.
 | |
| Discusses `<ng-container>`.
 | |
| Revised samples are more clear and cover all topics discussed.
 | |
| 
 | |
| ## NEW: Samples re-structured with `src/` folder (2017-02-02)
 | |
| All documentation samples have been realigned with the default folder structure of the Angular CLI.
 | |
| That's a step along the road to basing the sample in the Angular CLI.
 | |
| But it's also good in its own right.
 | |
| It helps clearly separate app code from setup and configuration files.
 | |
| 
 | |
| All samples now have a `src/` folder at the project root.
 | |
| The former `app/` folder moves under `src/`.
 | |
| Read about moving your existing project to this structure in
 | |
| <a href="https://github.com/angular/quickstart#updating-to-a-newer-version-of-the-quickstart-repo" target="Migrating samples/quickstart app to the src folder">
 | |
| the QuickStart repo update instructions</a>.
 | |
| 
 | |
| Notably:
 | |
| 
 | |
| * `app/main.ts` moved to `src/main.ts`.
 | |
| * `app/` moved to `src/app/`.
 | |
| * `index.html`, `styles.css` and `tsconfig.json` moved inside `src/`.
 | |
| * `systemjs.config.js` now imports `main.js` instead of `app`.
 | |
| * Added `lite-server` configuration (`bs-config.json`) to serve `src/`.
 | |
| 
 | |
| ## NEW: Reactive Forms guide (2017-01-31)
 | |
| The new [**Reactive Forms**](guide/reactive-forms) guide explains how and why to build a "reactive form".
 | |
| "Reactive Forms" are the code-based counterpart to the declarative "Template Driven" forms approach
 | |
| introduced in the [Forms](guide/forms) guide.
 | |
| Check it out before you decide how to add forms to your app.
 | |
| Remember also that you can use both techniques in the same app,
 | |
| choosing the approach that best fits each scenario.
 | |
| 
 | |
| ## NEW: Deployment guide (2017-01-30)
 | |
| 
 | |
| The new [Deployment](guide/deployment) guide describes techniques for putting your application on a server.
 | |
| It includes important advice on optimizing for production.
 | |
| 
 | |
| ## Hierarchical Dependency Injection: refreshed (2017-01-13)
 | |
| 
 | |
| [Hierarchical Dependency Injection](guide/hierarchical-dependency-injection) guide is significantly revised.
 | |
| Closes issue #3086.
 | |
| Revised samples are clearer and cover all topics discussed.
 | |
| 
 | |
| ## Miscellaneous (2017-01-05)
 | |
| 
 | |
| * [Setup](guide/setup) guide:
 | |
| added (optional) instructions on how to remove _non-essential_ files.
 | |
| * No longer consolidate RxJS operator imports in `rxjs-extensions` file; each file should import what it needs.
 | |
| * All samples prepend template/style URLs with `./` as a best practice.
 | |
| * [Style Guide](guide/styleguide): copy edits and revised rules.
 | |
| 
 | |
| ## Router: more detail (2016-12-21)
 | |
| 
 | |
| Added more information to the [Router](guide/router) guide
 | |
| including sections named outlets, wildcard routes, and preload strategies.
 | |
| 
 | |
| ## HTTP: how to set default request headers (and other request options) (2016-12-14)
 | |
| 
 | |
| Added section on how to set default request headers (and other request options) to
 | |
| HTTP guide.
 | |
| 
 | |
| ## Testing: added component test plunkers (2016-12-02)
 | |
| 
 | |
| Added two plunkers that each test _one simple component_ so you can write a component test plunker of your own: <live-example name="setup" plnkr="quickstart-specs">one</live-example> for the QuickStart seed's `AppComponent` and <live-example name="testing" plnkr="banner-specs">another</live-example> for the Testing guide's `BannerComponent`.
 | |
| Linked to these plunkers in [Testing](guide/testing#live-examples) and [Setup anatomy](guide/setup-systemjs-anatomy) guides.
 | |
| 
 | |
| ## Internationalization: pluralization and _select_ (2016-11-30)
 | |
| 
 | |
| The [Internationalization (i18n)](guide/i18n) guide explains how to handle pluralization and
 | |
| translation of alternative texts with `select`.
 | |
| The sample demonstrates these features too.
 | |
| 
 | |
| ## Testing: karma file updates (2016-11-30)
 | |
| 
 | |
| * `karma.config` + `karma-test-shim` can handle multiple spec source paths;
 | |
| see quickstart issue: [angular/quickstart#294](https://github.com/angular/quickstart/issues/294).
 | |
| * Displays Jasmine Runner output in the karma-launched browser.
 | |
| 
 | |
| ## QuickStart Rewrite (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](guide/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.
 | |
| 
 | |
| ## Sync with Angular v.2.2.0 (2016-11-14)
 | |
| 
 | |
| Docs and code samples updated and tested with Angular v.2.2.0.
 | |
| 
 | |
| ## UPDATE: NgUpgrade Guide for the AOT friendly _upgrade/static_ module (2016-11-14)
 | |
| 
 | |
| The updated [NgUpgrade Guide](guide/upgrade) guide covers the
 | |
| new AOT friendly `upgrade/static` module
 | |
| released in v.2.2.0, which is the recommended
 | |
| facility for migrating from AngularJS to Angular.
 | |
| The documentation for the version prior to v.2.2.0 has been removed.
 | |
| 
 | |
| ## ES6  described in "TypeScript to JavaScript" (2016-11-14)
 | |
| 
 | |
| The updated TypeScript to JavaScript guide (removed August 2017, PR #18694)
 | |
| explains how to write apps in ES6/7
 | |
| by translating the common idioms in the TypeScript documentation examples
 | |
| (and elsewhere on the web) to ES6/7 and ES5.
 | |
| 
 | |
| ## Sync with Angular v.2.1.1 (2016-10-21)
 | |
| 
 | |
| Docs and code samples updated and tested with Angular v.2.1.1.
 | |
| 
 | |
| ## npm _@types_ packages replace _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.
 | |
| 
 | |
| The [AngularJS Upgrade](guide/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 development.
 | |
| 
 | |
| ## "Template Syntax" explains two-way data binding syntax (2016-10-20)
 | |
| 
 | |
| Demonstrates how to two-way data bind to a custom Angular component and
 | |
| re-explains `[(ngModel)]` in terms of the basic `[()]` syntax.
 | |
| 
 | |
| ## BREAKING CHANGE: `in-memory-web-api` (v.0.1.11) delivered as esm umd (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 <a href="https://github.com/angular/in-memory-web-api/blob/master/CHANGELOG.md#0113-2016-10-20">change note</a>
 | |
| in the `in-memory-web-api` repo.
 | |
| 
 | |
| ## "Router" _preload_ syntax and _:enter_/_:leave_ animations (2016-10-19)
 | |
| 
 | |
| The router can lazily _preload_ modules _after_ the app starts and
 | |
| _before_ the user navigates to them for improved perceived performance.
 | |
| 
 | |
| New `:enter` and `:leave` aliases make animation more natural.
 | |
| 
 | |
| ## Sync with Angular v.2.1.0 (2016-10-12)
 | |
| 
 | |
| Docs and code samples updated and tested with Angular v.2.1.0.
 | |
| 
 | |
| ## NEW "Ahead of time (AOT) Compilation" guide (2016-10-11)
 | |
| 
 | |
| The NEW [Ahead of time (AOT) Compilation](guide/aot-compiler) guide
 | |
| explains what AOT compilation is and why you'd want it.
 | |
| It demonstrates the basics with a QuickStart app
 | |
| followed by the more advanced considerations of compiling and bundling the Tour of Heroes.
 | |
| 
 | |
| ## Sync with Angular v.2.0.2 (2016-10-6)
 | |
| 
 | |
| Docs and code samples updated and tested with Angular v.2.0.2.
 | |
| 
 | |
| ## "Routing and Navigation" guide with the _Router Module_ (2016-10-5)
 | |
| 
 | |
| The [Routing and Navigation](guide/router) guide now locates route configuration
 | |
| in a _Routing Module_.
 | |
| The _Routing Module_ replaces the previous _routing object_ involving the `ModuleWithProviders`.
 | |
| 
 | |
| All guided samples with routing use the _Routing Module_ and prose content has been updated,
 | |
| most conspicuously in the
 | |
| [NgModule](guide/ngmodule) guide and [NgModule FAQ](guide/ngmodule-faq) guide.
 | |
| 
 | |
| ## New "Internationalization" guide (2016-09-30)
 | |
| 
 | |
| Added a new [Internationalization (i18n)](guide/i18n) guide that shows how
 | |
| to use Angular "i18n" facilities to translate template text into multiple languages.
 | |
| 
 | |
| ## "angular-in-memory-web-api" package rename (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.
 | |
| 
 | |
| 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.
 | |
| <a href="https://github.com/angular/in-memory-web-api/blob/master/README.md">Read about them on github</a>.
 | |
| 
 | |
| ## "Style Guide" with _NgModules_ (2016-09-27)
 | |
| 
 | |
| [StyleGuide](guide/styleguide) explains recommended conventions for NgModules.
 | |
| 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.
 | |
| Also relaxed the rule that discouraged use of the `@Component.host` property.
 | |
| 
 | |
| ## _moduleId: module.id_ everywhere (2016-09-25)
 | |
| 
 | |
| Sample components that get their templates or styles with `templateUrl` or `styleUrls`
 | |
| have been converted to _module-relative_ URLs.
 | |
| Added the `moduleId: module.id` property-and-value to their `@Component` metadata.
 | |
| 
 | |
| This change is a requirement for compilation with AOT compiler when the app loads
 | |
| modules with SystemJS as the samples currently do.
 | |
| 
 | |
| ## "Lifecycle Hooks" guide simplified (2016-09-24)
 | |
| 
 | |
| The [Lifecycle Hooks](guide/lifecycle-hooks) guide is shorter, simpler, and
 | |
| draws more attention to the order in which Angular calls the hooks.
 |
