React 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/react:component
generator with the command:
~/myorg❯
npx nx g @nrwl/react:component banner --project=common-ui --export
> NX Generating @nrwl/react:component
CREATE libs/common-ui/src/lib/banner/banner.module.css
CREATE libs/common-ui/src/lib/banner/banner.spec.tsx
CREATE libs/common-ui/src/lib/banner/banner.tsx
UPDATE libs/common-ui/src/index.ts
Then create a simple Banner
component in the generated file:
export interface BannerProps {
text: string;
}
export function Banner(props: BannerProps) {
return <header>{props.text}</header>;
}
export default Banner;
admin
Add the Banner
component to the admin app:
import { Banner } from '@myorg/common-ui';
export function App() {
return (
<>
<Banner text="Welcome to our admin app." />
<div />
</>
);
}
export default App;
products
Export a Product
TS interface and some example products:
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:
import { Banner } from '@myorg/common-ui';
import { exampleProducts } from '@myorg/products';
// eslint-disable-next-line @typescript-eslint/no-unused-vars
export function App() {
return (
<>
<Banner text="Welcome to the store!" />
<ul>
{exampleProducts.map((product) => (
<li key={product.id}>
<strong>{product.name}</strong> Price: {product.price}
</li>
))}
</ul>
</>
);
}
export default App;
Now run npx nx graph
again:
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.
