# Angular Modules (NgModules) have landed in Angular RC5!
|
||||||
|
|
||||||
|
_Angular Modules_, also known as _NgModules_, are the powerful new way to organize and bootstrap your Angular application.
|
||||||
|

|
||||||
|
Read more in the ["RC5 and NgModules" announcement](https://angularjs.blogspot.com).
|
||||||
|
|
||||||
|
Learn the details of NgModule in the [Angular Module](../guide/ngmodule) chapter.
|
||||||
|

|
||||||
|
The new `@NgModule` decorator gives you module-level components, directives, and pipes without
|
||||||
|
the need to specify them repeatedly in every component of your application.
|
||||||
|
|
||||||
|
The `@NgModule` metadata give the Angular compiler the context needed so that you can use the same code
|
||||||
|
regardless of whether you are running Angular in [Ahead of Time](../glossary.html#aot) or [Just in Time](../glossary.html#jit) mode.
|
||||||
|
|
||||||
|
## How do I use them?
|
||||||
|
|
||||||
|
If you were previously writing an Angular application, your app should continue to work in RC5.
|
||||||
|
We’ve worked hard to ensure that applications that worked with RC4 continue to work while you migrate.
|
||||||
|
For this to work, we’re doing 2 things automatically for you:
|
||||||
|
|
||||||
|
* We create an implicit `NgModule` for you as part of the `bootstrap()` command
|
||||||
|
* We automatically hoist your components, pipes, and directives
|
||||||
|
|
||||||
|
While your application will continue to work today,
|
||||||
|
it’s important that you update your application to ensure future updates and deprecations don’t negatively affect you.
|
||||||
|
To make it easier, you can think of the process as having 5 steps.
|
||||||
|
|
||||||
|
1. **Update to RC5** - Your application should continue to work without modification, but it’s important that you are running the latest version of Angular.
|
||||||
|
|
||||||
|
2. **Create an _NgModule_** - Create the root `NgModule` that you’ll use to bootstrap your application.
|
||||||
|
|
||||||
|
3. **Update your bootstrap** - Bootstrap that module instead of your root component
|
||||||
|
|
||||||
|
4. **Update your 3rd party libraries** - Take advantage of the latest from Forms, Material, Http, and more
|
||||||
|
|
||||||
|
5. **Cleanup** - Clean up your code.
|
||||||
|
The deprecated classes, methods and properties will be removed from Angular very soon.
|
||||||
|
|
||||||
|
Prefer to look at code and diffs?
|
||||||
|
Check out the upgrade in [one commit](https://github.com/StephenFluin/ngmodule-migration/commit/9f9c6ae099346e491fc31d77bf65ed440e1f164c).
|
||||||
|
|
||||||
|
## 1. Update to RC5
|
||||||
|
If you use npm, you should be able to either update your package.json file and run npm install.
|
||||||
|
Or alternatively you can run the following command:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
npm install @angular/{core,common,compiler,angular-cli,platform-browser,platform-browser-dynamic}@2.0.0-rc.5 --save
|
||||||
|
```
|
||||||
|
|
||||||
|
You should also update any libraries you are using
|
||||||
|
|
||||||
|
```bash
|
||||||
|
npm install @angular/router@3.0.0-rc.1
|
||||||
|
npm install @angular/forms@1.0.0-rc.1
|
||||||
|
npm install @angular2-material/{button,card,toolbar,etc}@experimental
|
||||||
|
```
|
||||||
|
|
||||||
|
## 2. Create an NgModule
|
||||||
|
Create a new file called app.module.ts. Populate it with your root component as follows:
|
||||||
|
|
||||||
|
```javascript
|
||||||
|
import { NgModule } from '@angular/core';
|
||||||
|
import { BrowserModule } from '@angular/platform-browser';
|
||||||
|
import { AppComponent } from './app.component';
|
||||||
|
|
||||||
|
@NgModule({
|
||||||
|
declarations: [AppComponent],
|
||||||
|
imports: [BrowserModule],
|
||||||
|
bootstrap: [AppComponent],
|
||||||
|
})
|
||||||
|
export class AppModule {}
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
## 3. Update your bootstrap
|
||||||
|
Update your `main.ts` file to bootstrap using the Just in Time compiler.
|
||||||
|
|
||||||
|
```javascript
|
||||||
|
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
|
||||||
|
import { AppModule } from './app/app.module';
|
||||||
|
|
||||||
|
platformBrowserDynamic().bootstrapModule(AppModule);
|
||||||
|
```
|
||||||
|
|
||||||
|
## 4. Update your 3rd party libraries
|
||||||
|
Remove any 3rd party libraries from you AppComponent’s providers.
|
||||||
|
You’ll want to move these to your NgModule’s imports, while updating to use each library’s provided Module(s).
|
||||||
|
|
||||||
|
```javascript
|
||||||
|
imports: [
|
||||||
|
BrowserModule,
|
||||||
|
// Router
|
||||||
|
RouterModule.forRoot(config),
|
||||||
|
// Forms
|
||||||
|
FormsModule,
|
||||||
|
// Material Design
|
||||||
|
MdSlideToggleModule,
|
||||||
|
MdButtonModule,
|
||||||
|
MdToolbarModule,
|
||||||
|
MdCardModule,
|
||||||
|
MdInputModule,
|
||||||
|
],
|
||||||
|
```
|
||||||
|
|
||||||
|
## 5. Cleanup
|
||||||
|
As of RC5, we allow you to leave `directives` and `pipes` in your `@Component` decorators.
|
||||||
|
In fact, we automatically hoist (add) them to the NgModule that they belong to.
|
||||||
|
|
||||||
|
.alert.is-important
|
||||||
|
:marked
|
||||||
|
This behavior is provided temporarily for backward compatibility. It will soon be removed.
|
||||||
|
|
||||||
|
Stay ahead of this deprecation by removing them from your components and placing them into your `NgModule` declarations
|
||||||
|
as soon as possible.

Angular applications can be compiled by developers at build-time.
|
||||||
|
By compiling your application using the compiler-cli, `ngc`, you can boostrap directly
|
||||||
|
to a Module Factory, meaning you don't need to include the Angular compiler in your javascript bundle.
|
||||||
|
Ahead of Time compiled applications also benefit from decreased load time and increased performance.

With Angular _Just in Time_ bootstrapping you compile your components and modules in the browser
|
||||||
|
and launch the application dynamically. This is a good choice during development.
|
||||||
|
Consider the [Ahead of Time](#aot) mode for production apps.
