+
+The goal of this challenge is to use a React component inside an Angular application.
+
+Many components are available in React, and it can be interesting to use them in an Angular application. The goal is to create a React component and use it in an Angular application.
+
+## Information
+
+In this challenge, we have a simple application and a React component `ReactPost` in `app/react` to illustrate a React component from a library.
+
+## Statement
+
+- Your task is to display the posts with the React component `ReactPost`.
+- When you select a post, the post should be highlighted.
+
+In order to play with the React component, you should start by installing the React dependencies.
+
+```bash
+npm i --save react react-dom
+npm i --save-dev @types/react @types/react-dom
+```
+
+## Constraints
+
+- Do not transform the React component into an Angular component. The React component is pretty simple and can be written with ease in Angular. But **the goal is to use the React component**.
+
+### Hint
+
+<details>
+  <summary>Hint 1 - Configuration</summary>
+  Allow the React files in tsconfig.json
+
+```
+{
+...
+"compilerOptions": {
+  ...
+  "jsx": "react"
+},
+...
+}
+```
+
+</details>
+
+<details>
+  <summary>Hint 2 - Initialization</summary>
+  Create a react root with `createRoot(...)`
+</details>
+
+<details>
+  <summary>Hint 3 - Display</summary>
+  To render the component, it should look like this:
+
+    ```
+    <react root>.render(
+        <React.StrictMode>
+        ...
+        </React.StrictMode>
+    )
+    ```
+
+</details>
+
+<details>
+  <summary>Hint 4 - Design</summary>
+  Do not forget to allow the react file in Tailwind.

+
+:::note[Nota]
+Este exercício pode ser obsoleto com o novo controle de fluxo e do bloco de empty state dentro do bloco `@for`. No entanto, **diretivas estruturais** não serão removidas tão cedo, por isso você ainda pode aprender bastante com este exercício.
+:::
+
+## Informação
+
+Diretiva é uma ferramente poderosa oferecida pelo framework Angular. Você pode usar o princípio DRY compartilhando a lógica dentro de uma diretiva e aplicando ela em qualquer componente que quiser.
+
+Mas a verdadeira vantagem é que você consegue melhorar uma diretiva pré-existente que não **pertence** a você.
+
+## Declaração
+
+Neste exercício, queremos mostrar uma lista de pessoas. Se a lista está vazio, você deve mostrar _" the list is empty !! "_.
+
+Atualmente, temos:
+
+```typescript
+    <ng-container *ngIf="persons.length > 0; else emptyList">
+      <div *ngFor="let person of persons">
+        {{ person.name }}
+      </div>
+    </ng-container>
+    <ng-template #emptyList>The list is empty !!</ng-template>
+```
+
+Queremos nos livrar do `ng-container` escrevendo:
+
+```typescript
+    <div *ngFor="let person of persons; empty: emptyList">
+    {{ person.name }}
+    </div>
+    <ng-template #emptyList>The list is empty !!</ng-template>
+```
+
+Objetivo é **melhorar a diretiva ngFor**.
