For instance, if we want to stop doing challenge after 30 days we can increment the day from 1 to 30 and we can block the application at day 30.
Look the example.
```js
import React, { Component } from 'react'
import ReactDOM from 'react-dom'
class App extends Component {
constructor(props) {
super(props)
console.log('I am the constructor and I will be the first to run.')
this.state = {
firstName: 'John',
day: 1,
}
}
shouldComponentUpdate(nextProps, nextState) {
console.log(nextProps, nextState)
console.log(nextState.day)
if (nextState.day > 31) {
return false
} else {
return true
}
}
// the doChallenge increment the day by one
doChallenge = () => {
this.setState({
day: this.state.day + 1,
})
}
render() {
return (
<div className='App'>
<h1>React Component Life Cycle</h1>
<button onClick={this.doChallenge}>Do Challenge</button>
<p>Challenge: Day {this.state.day}</p>
{this.state.congratulate && <h2>{this.state.congratulate}</h2>}
</div>
)
}
}
const rootElement = document.getElementById('root')
ReactDOM.render(<App />, rootElement)
```
### render ### render
As we have mentioned it on the mounting phase of the component, the render() method is called when a component gets updated. It has to re-render the HTML to the DOM, with the new changes.

# Third Party Packages
There are more than 1.4M JavaScript on npm registry. By now there is a package for every kind of problem. We do not have to create the wheel instead we have to know how to use the wheel. In this section, we will learn how to use npm packages and also we will implement most common package for React applications. As of October 10, 2020, the npm registry popular packages, total number of packages, downloads per week and downloads per month.
![NPM packages](../images/npm_package_day_15.png)
In one way or the other you many need the following packages in your React applications.
- [node-sass](https://www.npmjs.com/package/node-sass)
- [moment](https://www.npmjs.com/package/moment)
- [axios](https://www.npmjs.com/package/axios)
- [react-icons](https://react-icons.github.io/react-icons/)
- [styled-components](https://styled-components.com/)
- [reactstrap](https://reactstrap.github.io/)
- [lodash](https://www.npmjs.com/package/lodash)
- [uuid](https://www.npmjs.com/package/uuid)
## NPM or Yarn
You can use either npm or yarn to install packages. If you want to use [yarn](https://yarnpkg.com) you have install it separately. I would recommend you to stick in one of the package. Don't use both package management tools in one application at the same time.
Let's how to install packages to an application. First we go to the project directory and write the following command.
```sh
// syntax, we can use i or install
npm i package-name
```
### node-sass
Sass is a CSS preprocess which allows to write CSS function, nesting and many more. Let's install node-sass to make use of the power of Sass.
Using npm:
```sh
Asabeneh@DESKTOP-KGC1AKC MINGW64 ~/Desktop/30-days-of-react$ npm install node-sass
```
Using yarn:
```sh
Asabeneh@DESKTOP-KGC1AKC MINGW64 ~/Desktop/30-days-of-react$ yarn add node-sass
```
After installing node-sass you can start using Sass in React. Create a styles folder and inside this folder create test.scss. Import this file to the component you are working or index.js. You don't need import the node-sass to the component.
```js
// index.js
import './styles/test.scss
```
### axios
Axios is a JavaScript library which can make HTTP requests to fetch data. In this section we will see on a get request. However, it is possible to do all the request types using [axios](https://github.com/axios/axios) (GET, POST, PUT, PATCH, DELETE).
Using npm:
```sh
Asabeneh@DESKTOP-KGC1AKC MINGW64 ~/Desktop/30-days-of-react$ npm install axios
```
Using yarn:
```sh
Asabeneh@DESKTOP-KGC1AKC MINGW64 ~/Desktop/30-days-of-react$ yarn add axios
```
```js
import React, { Component } from 'react'
// axios is a package which
// send requests to a server to fetch data
import axios from 'axios'
import ReactDOM from 'react-dom'
class App extends Component {
state = {
data: [],
}
componentDidMount() {
const API_URL = 'https://restcountries.eu/rest/v2/all'
axios
.get(API_URL)
.then((response) => {
this.setState({
data: response.data,
})
})
.catch((error) => {
console.log(error)
})
}
renderCountries = () => {
return this.state.data.map((country) => {
const languageOrLanguages =
country.languages.length > 1 ? 'Langauges' : 'Language'
const formatLanguages = country.languages
.map(({ name }) => name)
.join(', ')
return (
<div>
<div>
{' '}
<img src={country.flag} alt={country.name} />{' '}
</div>
<div>
<h1>{country.name}</h1>
<p>Capital: {country.capital}</p>
<p>
{languageOrLanguages}: {formatLanguages}
</p>
<p>Population: {country.population}</p>
</div>
</div>
)
})
}
render() {
return (
<div className='App'>
<h1>Fetching Data Using Axios</h1>
<div>
<p>There are {this.state.data.length} countries in the api</p>
<div className='countries-wrapper'>{this.renderCountries()}</div>
</div>
</div>
)
}
}
const rootElement = document.getElementById('root')
ReactDOM.render(<App />, rootElement)
```
### react-icons
Icons are integral part of a website. To get different SVG icons
Using npm:
```sh
Asabeneh@DESKTOP-KGC1AKC MINGW64 ~/Desktop/30-days-of-react$ npm install react-icons
```
Using yarn:
```sh
Asabeneh@DESKTOP-KGC1AKC MINGW64 ~/Desktop/30-days-of-react$ yarn add react-icons
```
```js
import React, { Component } from 'react'
import axios from 'axios'
import ReactDOM from 'react-dom'
import moment from 'moment'
import {
TiSocialLinkedinCircular,
TiSocialGithubCircular,
TiSocialTwitterCircular,
} from 'react-icons/ti'
const Footer = () => (
<footer>
<h3>30 Days Of React</h3>
<div>
<TiSocialLinkedinCircular />
<TiSocialGithubCircular />
<TiSocialTwitterCircular />
</div>
<div>
<small> Copyright &copy; {new Date().getFullYear()} </small>
</div>
</footer>
)
class App extends Component {
render() {
return (
<div className='App'>
<h1>Welcome to the world of Icons</h1>
<Footer />
</div>
)
}
}
const rootElement = document.getElementById('root')
ReactDOM.render(<App />, rootElement)
```
### moment
Moment is a small JavaScript library which gives us different time formats.
```sh
npm install moment
```
```js
import React, { Component } from 'react'
import ReactDOM from 'react-dom'
class App extends Component {
render() {
return (
<div className='App'>
<h1>How to use moment</h1>
<p>This challenge was started {moment('2020-10-01').fromNow()}</p>
<p>The challenge will be over in {moment('2020-10-30').fromNow()}</p>
<p>Today is {moment(new Date()).format('MMMM DD, YYYY HH:mm')}</p>
</div>
)
}
}
const rootElement = document.getElementById('root')
ReactDOM.render(<App />, rootElement)
```
### styled-components
It uses a tagged template literals to style a component. It removes the mapping between components and styles. This means that when you're defining your styles, you're actually creating a normal React component, that has your styles attached to it.
```js
import React, { Component } from 'react'
import ReactDOM from 'react-dom'
import styled from 'styled-components'
const Title = styled.h1`
font-size: 70px;
font-weight: 300;
`
const Header = styled.header`
background-color: #61dbfb;
padding: 25;
padding: 10px;
margin: 0;
`
class App extends Component {
render() {
return (
<div className='App'>
<Header>
<Title>30 Days Of React</Title>
<h2>Getting Started React</h2>
<h3>JavaScript Library</h3>
<p>Instructor: Asabeneh Yetayeh</p>
<small>Oct 15, 2020</small>
</Header>
</div>
)
}
}
const rootElement = document.getElementById('root')
ReactDOM.render(<App />, rootElement)
```
### reactstrap
The [reactstrap](https://reactstrap.github.io/) package allows to use a component with bootstrap.
### lodash
According to the official lodash documentation, 'A modern JavaScript utility library delivering modularity, performance & extras.'
