taskTracker

Hi,:wave: this is my first React project, I chose to build a task tracker to learn all the basics and get a good understanding how Reactjs framework works.
Note: Go to the Build-code branch to get the production code for this project and how to deploy it on your machine.

During this project had the chance to learn all the following about React

Set up my first react development envierment
by running the following command:
npx crear-react-app my-app

How to creat a class Component:

export default class Header extends React.Component{
constructor(props) {
    super(props);
    this.state = {}
}
    render()  {
        return (
            <div>
	<h1> My Header </h1>
            </div>
        )

   }
}

How to creat a function Component:

export const Header = () => {

      const name = ‘reda’

      return (
            <div>
	<h1> Hi {name} </h1>
            </div>
}

Calling a component:

Import Header from ‘./Header’;

 and use:  <Header />

Passing props to components:

< Component name=’reda’ />

setting a propsType:

Component.propTypes = {
name: PropTypes.string
}
{string, number, bool, func, array, object...}

Events:

<Button onClick={buttonClicked} />
<input  type="text"  onChange={e => console.log(e.target.value)} />

useState Hook:

The React useState Hook allows us to track state in a function component.
1 – Import the hook:

import { useState } from "react";

2 - Initialize useState:

const [variabl, setVariable] = useState([one, two, three]);

variable: is the name of our state.
SetVariable: the function we use to update our state.
UseState: the initial state of our state.

UseEffect:

UseEffect( ()=>{ } ) when we want something to happen right after page loads.

Lists & .map(key):

const numbers = [1, 2, 3, 4, 5];
const listItems = numbers.map((number) => <li>{number}</li>);

const users = [{name:’reda’, age:25},{name:’john’, age:28}];
const usersAge = users.map((key) => <p>{key.age}</p>);

React-icons:

1 - install react icons: npm I react-icons
2 - import to file: import {FaTimes} from 'react-icons/fa'
3 – use the icons in code: <FaTimes />

React Build Version:

After finishig the app we can create a statc version.
npm run build (Creat new folder named build with all files)
