# Angular Monorepo Tutorial - Part 2: Project Graph
|
|
|
|
Run the command: `npx nx graph`. A browser should open up with the following contents:
|
|
|
|
|
|
|
|
This is still different than the design from the start of Part 1:
|
|
|
|
|
|
|
|
The Project Graph is derived from the source code of your workspace. Make the following adjustments to your existing projects, so that our Project Graph will match the design:
|
|
|
|
### `common-ui`
|
|
|
|
Run the `@nrwl/angular:component` generator with the command:
|
|
|
|
```{% command="npx nx g @nrwl/angular:component banner --project=common-ui --export" path="~/myorg" %}
|
|
|
|
> NX Generating @nrwl/angular:component
|
|
|
|
CREATE libs/common-ui/src/lib/banner/banner.component.css
|
|
CREATE libs/common-ui/src/lib/banner/banner.component.html
|
|
CREATE libs/common-ui/src/lib/banner/banner.component.spec.ts
|
|
CREATE libs/common-ui/src/lib/banner/banner.component.ts
|
|
UPDATE libs/common-ui/src/lib/common-ui.module.ts
|
|
UPDATE libs/common-ui/src/index.ts
|
|
```
|
|
|
|
Then create a simple `Banner` component in the generated file:
|
|
|
|
```javascript {% fileName="libs/common-ui/src/lib/banner/banner.component.ts" %}
|
|
import { Component, Input } from '@angular/core';
|
|
|
|
@Component({
|
|
selector: 'myorg-banner',
|
|
template: `<header>{{ title }}</header>`,
|
|
styleUrls: ['./banner.component.css'],
|
|
})
|
|
export class BannerComponent {
|
|
@Input() title = '';
|
|
}
|
|
```
|
|
|
|
### `admin`
|
|
|
|
Add the `Banner` component to the admin app:
|
|
|
|
```javascript {% fileName="apps/admin/src/app/app.component.ts" %}
|
|
import { Component } from '@angular/core';
|
|
|
|
@Component({
|
|
selector: 'myorg-root',
|
|
template: `
|
|
<myorg-banner title="Welcome to our admin app."> </myorg-banner>
|
|
`,
|
|
})
|
|
export class AppComponent {}
|
|
```
|
|
|
|
```javascript {% fileName="apps/admin/src/app/app.module.ts" %}
|
|
import { NgModule } from '@angular/core';
|
|
import { BrowserModule } from '@angular/platform-browser';
|
|
import { CommonUiModule } from '@myorg/common-ui';
|
|
|
|
import { AppComponent } from './app.component';
|
|
import { NxWelcomeComponent } from './nx-welcome.component';
|
|
|
|
@NgModule({
|
|
declarations: [AppComponent, NxWelcomeComponent],
|
|
imports: [BrowserModule, CommonUiModule],
|
|
providers: [],
|
|
bootstrap: [AppComponent],
|
|
})
|
|
export class AppModule {}
|
|
```
|
|
|
|
### `products`
|
|
|
|
Export a `Product` TS interface and some example products:
|
|
|
|
```javascript {% fileName="libs/products/src/lib/products.ts" %}
|
|
export interface Product {
|
|
id: string;
|
|
name: string;
|
|
price: number;
|
|
}
|
|
|
|
export const exampleProducts: Product[] = [
|
|
{
|
|
id: '1',
|
|
name: 'Product 1',
|
|
price: 100,
|
|
},
|
|
{
|
|
id: '2',
|
|
name: 'Product 2',
|
|
price: 200,
|
|
},
|
|
];
|
|
```
|
|
|
|
### `store`
|
|
|
|
Use both the `Banner` component from your `common-ui` lib, and the `exampleProducts` from your `products` lib:
|
|
|
|
```javascript {% fileName="apps/store/src/app/app.component.ts" %}
|
|
import { exampleProducts } from '@myorg/products';
|
|
import { Component } from '@angular/core';
|
|
|
|
@Component({
|
|
selector: 'myorg-root',
|
|
template: `
|
|
<myorg-banner title="Welcome to the store!"> </myorg-banner>
|
|
<ul>
|
|
<li *ngFor="let product of products">
|
|
<strong>{{ product.name }}</strong> Price: {{ product.price }}
|
|
</li>
|
|
</ul>
|
|
`,
|
|
})
|
|
export class AppComponent {
|
|
products = exampleProducts;
|
|
}
|
|
```
|
|
|
|
```javascript {% fileName="apps/store/src/app/app.module.ts" %}
|
|
import { NgModule } from '@angular/core';
|
|
import { BrowserModule } from '@angular/platform-browser';
|
|
import { CommonUiModule } from '@myorg/common-ui';
|
|
|
|
import { AppComponent } from './app.component';
|
|
import { NxWelcomeComponent } from './nx-welcome.component';
|
|
|
|
@NgModule({
|
|
declarations: [AppComponent, NxWelcomeComponent],
|
|
imports: [BrowserModule, CommonUiModule],
|
|
providers: [],
|
|
bootstrap: [AppComponent],
|
|
})
|
|
export class AppModule {}
|
|
```
|
|
|
|
Now run `npx nx graph` again:
|
|
|
|
{% side-by-side %}
|
|
|
|
|
|
|
|
{% /side-by-side %}
|
|
|
|
Your graph now matches the original design.
|
|
|
|
The Project Graph is more than just a visualization - Nx provides tooling to optimize your task-running and even automate your CI based on this graph. This will be covered in more detail in: [4: Workspace Optimization](/angular-tutorial/4-workspace-optimization).
