Currently, I am experimenting with REACTJS to build a basic app featuring Transitions. In my project file, I have imported CSSTransitions and Group Transition. However, when attempting to implement CSSTransition for specific news items, the animations are not appearing. It seems like they are non-existent despite being wrapped within the component. Can someone assist me in identifying where I might be going wrong?
import React, { Component } from 'react';
import {CSSTransition, TransitionGroup} from 'react-transition-group';
import {Link} from 'react-router-dom';
import Axios from 'axios';
import {URL} from '../../../Config';
import styles from './NewsList.module.css';
export default class NewsList extends Component {
state={
items:[],
start: this.props.start,
end: this.props.start+this.props.amount,
amount: this.props.amount
}
componentWillMount(){
this.request(this.state.start,this.state.end)
}
request=(start,end)=>{
Axios.get(`${URL}/articles?_start=${start}&_end=${end}`)
.then(response=>{
this.setState({
items:[...this.state.items,...response.data]
})
})
}
loadMore=()=>{
let end = this.state.end + this.state.amount
this.request(this.state.end, end)
}
renderNews=(type)=>{
let template= null;
switch(type){
case('Card'):
template= this.state.items.map((item, i)=>(
<CSSTransition
classNames={{
enter: styles.newList_wrapper,
enterActive: styles.newList_wrapper_enter
}}
timeout= {500}
key={i}
>
<div>
<div className={styles.newslist_item}>
<Link to={`/articles/${item.id}`}>
<h2>{item.title}</h2>
</Link>
</div>
</div>
</CSSTransition>
)
);
break;
default:
template = null;
}
return template;
}
render() {
return (
<div>
<TransitionGroup
component="div"
className="list"
>
{this.renderNews(this.props.type)}
</TransitionGroup>
<div onClick={window.history.pushState({},"","/newpage")}>
Click Here for More News
</div>
</div>
);
}
}.newslist_item{
border: 1px solid #f2f2f2;
background: #ffffff;
margin-top: 0px;
padding: 8px 5px 0 5px;
}
.newslist_item h2{
font-size: 13px;
line-height: 21px;
margin: 5px 0;
color: #525252
}
.newslist_item a {
text-decoration:none;
}
.newsList_wrapper{
box-sizing: border-box;
opacity: 0;
transform: translateX(-100%);
transition: all .5s ease-in;
}
.newsList_wrapper_enter{
opacity: 1;
transform: translateX(0%);
