Change Log
|
|
|
|
@intro
|
|
An annotated history of recent documentation improvements.
|
|
|
|
@description
|
|
|
|
|
|
|
|
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" cookbook 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="_blank" 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/style-guide): 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/server-communication#override-default-request-options) 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)](cookbook/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](cookbook/ts-to-js) cookbook
|
|
now 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" target="_blank">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" cookbook (2016-10-11)
|
|
|
|
The NEW [Ahead of time (AOT) Compilation](cookbook/aot-compiler) cookbook
|
|
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](cookbook/ngmodule-faq) cookbook.
|
|
|
|
## New "Internationalization" Cookbook (2016-09-30)
|
|
|
|
Added a new [Internationalization (i18n)](cookbook/i18n) cookbook 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" target="_blank">Read about them on github</a>.
|
|
|
|
## "Style Guide" with _NgModules_ (2016-09-27)
|
|
|
|
[StyleGuide](guide/style-guide) explains recommended conventions for Angular modules (NgModule).
|
|
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. |
