Sorting Users and Implementing Animations on SUSI Web Chat Team Page

Sorting Users and Implementing Animations on SUSI Web Chat Team Page

While we were developing the chat application, we wanted to show details of Developers.  So we planned to build a team page for SUSI Web Chat Application. In this post I discuss few things we built there. Like sorting feature, animations of the page, usage of Material UI.

First we made an array of objects to store user details. In that array we grouped them in sub arrays so we can refer them in different sections separately. We stored following data in “TeamList.js” in an array.

var team = [{
 'mentors': [{
   'name': 'Mario Behling',
   'github': 'http://github.com/mariobehling',
   'avatar': 'http://fossasia.org/img/mariobehling.jpg',
   'twitter': 'https://twitter.com/mariobehling',
   'linkedin': 'https://www.linkedin.com/in/mariobehling/',
   'blog': '#'
 }]
},{ 'server': [{
    }]
}

There was a requirement to sort developers by their name so we had to build a way to sort out array data which are in main array. This is how we built that.
The function we are going to use for sorting.

   function compare(a, b) {
     if (a.name < b.name) { return -1; }
     if (a.name > b.name) { return 1; }
     return 0;
   }

This is how we have used it to sort developers.

import team from './TeamList';
team[1].server.sort(compare);

In this function we took values of object two by two and compared.
Now we have to show these sorted information on view.
Extract data that we want from array and we used material UI Cards to show these data on view.
This is how we extracted data from the array.

   team[1].server.sort(compare);
   let server = team[1].server.map((serv, i) => {
     return ( <Card className='team-card' key={i}>
         <CardMedia className="container" >
           <img src={serv.avatar} alt={serv.name} className="image" />
           <div className="overlay" >
             <div className="text"> <FourButtons member={serv} /> </div>
           </div>
         </CardMedia>
         <CardTitle title={serv.name} subtitle={serv.designation} />
       </Card>)   })

Now it shows data on the view.
“” contains an image of the member. We need to show social media links of the user on mouseover. We did that using simple CSS. I added a block comment around those particular styles. Check those styles here.

.overlay {
 position: absolute;
 bottom: 100%;
 left: 0;
 right: 0;
 background-color: #000;
 overflow: hidden;
 width: 100%;
 height:0;
 transition: .3s ease;
 opacity:0;
}
.container:hover .overlay {
 bottom: 0;
 height: 100%;
 opacity:0.7;
}

Above lines show that how we made the animation of the overlay animation.

Now we want to show social media buttons on the overlay. We made another separate component for buttons and return those like this.

render() {
       let member= this.props.member;
       return (<div>
         <CardActions>
           <IconButton href={member.github} target="_blank" >
  <CardActions>
		</div>)}

Finally we showed those data on Team page. We returned these JSX from render(){} method.

         <div className="team-header">
           <div className="support__heading">Developers</div>
         </div>
         <div className='team-container'>{server}</div>

I have mentioned few resources which I used to implement these features. If you are willing to contribute SUSI AI Web Chat application. Fork our repository on github.
