# Getting Started with Create React App
This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app). # my-product-management-system
## Objective:
By the end of this session, students will be able to create class and functional components, style components using CSS, and perform CRUD operations in React using MockAPI. The project will be named "my-product-management-system" and will include pages to register categories and products.
## Agenda:
### 1. Introduction (30 minutes)
- Overview of React components: class components vs functional components.
- Introduction to React's component lifecycle methods.
- Brief introduction to CSS in React.
- Introduction to MockAPI for CRUD operations.
### 2. Setting Up the Project (30 minutes)

<Router>
<div className="App">
<h1>Product Management System</h1>
</div>
</Router>
);
}
export default App;
\`\`\`

import React, { useState } from 'react';
import { createCategory } from '../../services/ApiCategory';
const CategoryFormFunction = ({ fetchCategories }) => {
const [categoryName, setCategoryName] = useState('');
const [description, setDescription] = useState('');
const handleChange = (event) => {
const { name, value } = event.target;
if (name === 'name') setCategoryName(value);
if (name === 'description') setDescription(value);
};
const handleSubmit = async (event) => {
event.preventDefault();
await createCategory({ name: categoryName, description });
setCategoryName('');
setDescription('');
fetchCategories();
};
return (
<form onSubmit={handleSubmit}>
<input
type="text"

<input
type="text"
name="description"
value={description}
onChange={handleChange}
placeholder="Category Description"
/>
<button type="submit">Add Category</button>
</form>
);
};
export default CategoryFormFunction;
\`\`\`
\`\`\`jsx
// CategoryListFunction.js
import React, { useEffect, useState } from 'react';
import { getCategories, deleteCategory, updateCategory } from '../../services/ApiCategory';
import './Category.css';

const CategoryListFunction = () => {
const [categories, setCategories] = useState([]);
const [isEditing, setIsEditing] = useState(false);
const [currentCategory, setCurrentCategory] = useState({ id: '', name: '', description: '' });
useEffect(() => {
fetchCategories();
}, []);
const fetchCategories = async () => {
const categories = await getCategories();
setCategories(categories);
};
const handleDelete = async (id) => {
await deleteCategory(id);
fetchCategories();
};
const handleEdit = (category) => {
setIsEditing(true);
setCurrentCategory(category);
};
const handleCancelEdit = () => {
setIsEditing(false);
setCurrentCategory({ id: '', name: '', description: '' });
};
const handleChange = (event) => {
const { name, value } = event.target;
setCurrentCategory((prevCategory) => ({
...prevCategory,
[name]: value,
}));
};
const handleUpdate = async (event) => {
event.preventDefault();
await updateCategory(currentCategory.id, {
name: currentCategory.name,
description: currentCategory.description,
});
setIsEditing(false);
setCurrentCategory({ id: '', name: '', description: '' });
fetchCategories();
};
return (
<div>
<h2>Categories</h2>
{isEditing ? (
<form onSubmit={handleUpdate}>

</div>
);
};
export default CategoryListFunction;
\`\`\`
### 6. Lunch Break (30 minutes)
### 7. Adding CSS (30 minutes)
- Demonstrate how to add and apply CSS in React.
- Style the category and product forms.
\`\`\`css
/* Category.css */
form {
margin: 20px;
}
input {
margin-right: 10px;
}
\`\`\`
### 8. Integrating MockAPI for CRUD Operations (60 minutes)
- Set up MockAPI for category and product management.
- Perform CRUD operations (Create, Read, Update, Delete) using MockAPI.
\`\`\`jsx
// ApiCategory.js
const apiUrl = 'https://mockapi.io/endpoint';
export const getCategories = () => fetch(apiUrl).then((res) => res.json());
export const createCategory = (category) =>
fetch(apiUrl, {
method: 'POST',
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify(category),
}).then((res) => res.json());
export const deleteCategory = (id) =>
fetch(\`\${apiUrl}/\${id}\`, {
method: 'DELETE',
}).then((res) => res.json());
export const updateCategory = (id, category) =>
fetch(\`\${apiUrl}/\${id}\`, {
method: 'PUT',
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify(category),
}).then((res) => res.json());
\`\`\`
### 9. Building Pages for Category and Product Registration (60 minutes)
- Create forms for category and product registration.
- Link forms to MockAPI for data submission.
\`\`\`jsx
// Example form structure with API integration
const handleSubmit = (event) => {
event.preventDefault();
createCategory({ name: categoryName, description }).then((data) => console.log(data));
};
return (
<form onSubmit={handleSubmit}>
<input type="text" placeholder="Enter category name" />
<button type="submit">Submit</button>
</form>
);
\`\`\`
- Implement similar logic for \`ProductForm.js\`.
### 10. Building Lists to Display Data (45 minutes)
- Create lists to display categories and products.
- Fetch data from MockAPI and render it in the components.
\`\`\`jsx
// CategoryListFunction.js
import React, { useEffect, useState } from 'react';
import { getCategories } from '../services/ApiCategory';
const CategoryListFunction = () => {
const [categories, setCategories] = useState([]);
useEffect(() => {
getCategories().then((data) => setCategories(data));
}, []);
return (
<div>
<h2>Category List</h2>
<ul>
{categories.map((category) => (
<li key={category.id}>{category.name}</li>
))}
</ul>
</div>
);
};
export default CategoryListFunction;
\`\`\`
- Implement similar logic for \`ProductList.js\`.
### 11. Routing Navigation (15 minutes)
- Modify \`App.js\` to include a welcome message and links to the category and product registration pages.
#### Step-by-Step Instructions:
1. **Install React Router:**
- Run the following command to install React Router:
\`\`\`bash
npm install react-router-dom
\`\`\`
2. **Modify App.js:**
- Replace the content of \`App.js\` with the following code:
\`\`\`jsx
import React from 'react';
import { BrowserRouter as Router, Route, Link } from 'react-router-dom';
import logo from './logo.svg';
import './App.css';
import CategoryListClass from './components/Category/CategoryListClass';
import CategoryFormClass from './components/Category/CategoryFormClass';
import CategoryListFunction from './components/Category/CategoryListFunction';
function App() {
return (
<Router>
<div className="App">
<h1>Product Management System</h1>
<nav>
<ul>
<li>
<Link to="/category">Register Category</Link>
</li>
<li>
<Link to="/product">Register Product</Link>
</li>
</ul>
</nav>
<Route path="/category" component={CategoryFormClass} />
<Route path="/product" component={CategoryListFunction} />
</div>
</Router>
);
}
export default App;
\`\`\`
### 13. Design Content Navigation (15 minutes)
- Modify \`App.js\` to include a welcome message and links to the category and product registration pages.
#### Step-by-Step Instructions:
1. **Modify App.js:**
- Replace the content of \`App.js\` with the following code:
\`\`\`jsx
import React from 'react';
import { BrowserRouter as Router, Route, Link } from 'react-router-dom';
import logo from './logo.svg';
import './App.css';
import CategoryListClass from './components/Category/CategoryListClass';
import CategoryFormClass from './components/Category/CategoryFormClass';
import CategoryListFunction from './components/Category/CategoryListFunction';
function App() {
return (
<Router>
<div className="App">
<h1>Product Management System</h1>
<div className="container">
<nav className="sidebar">
<ul>
<li>
<Link to="/category">Register Category</Link>
</li>
<li>
<Link to="/product">Register Product</Link>
</li>
</ul>
</nav>
<div className="content">
<Routes>
<Route path="/category" element={<CategoryListClass />} />
<Route path="/product" element={<CategoryListFunction />} />
</Routes>
</div>
</div>
</div>
</Router>
);
}
export default App;
\`\`\`
2. **Modify App.css:**
- Update to add the content of \`App.css\` with the following code:
\`\`\`css
.App {
font-family: sans-serif;
text-align: center;
}
.container {
display: flex;
height: 100vh;
}
.sidebar {
width: 200px;
background-color: #f8f9fa;
padding: 15px;
box-shadow: 2px 0 5px rgba(0, 0, 0, 0.1);
}
.sidebar ul {
list-style-type: none;
padding: 0;
}
.sidebar ul li {
margin: 10px 0;
}
.sidebar ul li a {
text-decoration: none;
color: #007bff;
font-weight: bold;
}
.content {
flex-grow: 1;
padding: 20px;
}
h1 {
margin: 20px;
}
\`\`\`
## Conclusion (15 minutes)
- Recap the key concepts covered.
- Q&A session to address any doubts or questions.
- Provide resources for further learning.
## Resources:
- [React Documentation](https://reactjs.org/docs/getting-started.html)
- [MockAPI Documentation](https://mockapi.io/docs)
- [CSS Tricks](https://css-tricks.com/)
- [React Router Documentation](https://reactrouter.com/web/guides/quick-start)
- [Redux Documentation](https://redux.js.org/)
### Advanced Topics
- Discuss state management with Context API.
- 3rd-Party libary like axios,sweertalert,formik,bootstrap/tailwind
- Implementing more complex forms and validation.
- Error handling and debugging tips.
This comprehensive 5-hour training module ensures that students gain an in-depth understanding of React components, styling, and CRUD operations, with ample time for hands-on practice and advanced topics.
## Available Scripts
In the project directory, you can run:
### `npm start`
Runs the app in the development mode.\
Open [http://localhost:3000](http://localhost:3000) to view it in your browser.
The page will reload when you make changes.\
You may also see any lint errors in the console.
### `npm test`
Launches the test runner in the interactive watch mode.\
See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.
### `npm run build`
Builds the app for production to the `build` folder.\
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.\
Your app is ready to be deployed!
See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
### `npm run eject`
**Note: this is a one-way operation. Once you `eject`, you can't go back!**
If you aren't satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.
You don't have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.
