💡 What’s the prupose of it?

Just fun 🙂. I love learn and code, so, this every time I have free time, pick some crazy idea or got inspiration from another projects and make it. 😋

🦄 Inspiration

When I saw the project of Mohit, react-insta-stories, immediately wanted to know how complicated it would be to do the same thing using Web Components. So, I built this. Thanks, Mohit! 😃

⚙️ How it works?

There are three components working together:

<wc-stories-story>: this component shows a image. The maximun size of an image is the containers viewport.
<wc-stories-progress>: this component shows the progress bar at top the the container. It uses Web Animations API to run it. If we change of image (clicking on left/right), the previous animation is cancelled.
<wc-stories>: this is the main component. This one harbor the two components above. Here is the logic for control which image should be revealed, what happen if the user
clicks on left or right side, etc.

🚀 How to run?

After install depenencies, you just need to run yarn start. Once the server was started, go to localhost:4444 and see it in action.

🛠️ How to build?

Execute the yarn build command to compile the source code and get the ES5 equivalent. Compiled code will be available on dist/ folder.

🙋 How to use it in my web/app?

First, we need to add the needed polyfills:

@webcomponents/webcomponentsjs/custom-elements-es5-adapter.js
@webcomponents/webcomponentsjs/webcomponents-loader.js.
web-animations-js/web-animations.min.js

Web Components/Vanilla JavaScript

If you’re using Web Components or vanilla JavaScript, just put the wc-stories tag inside your HTML and pass it the array of images:

<wc-stories height="480" width="320" withShadow>
  <wc-stories-story src="/img/01.jpg"></wc-stories-story>
  <wc-stories-story src="/img/02.jpg"></wc-stories-story>
  <wc-stories-story src="/img/03.jpg"></wc-stories-story>
  <wc-stories-story src="/img/04.jpg"></wc-stories-story>
  <wc-stories-story src="/img/05.jpg"></wc-stories-story>
</wc-stories>

React

If you’re using React, use the component as is. Instead of passing raw values you can use state to
store the component configuration:

export class MyComponent extends React.Component {
  this.state = {
    width: 320,
    height: 480,
    withShadow: true,
    stories: [
      '/path/to/image',
      '/path/to/image',
      '/path/to/image',
      ...
    ]
  }
  render() {
    return (
      <wc-stories
        width={this.state.height}
        height={this.state.width}
        withShadow={this.state.withShadow}
      >
      {
        this.state.stories.map(story => (
          <wc-stories-story src={story} ></wc-stories-story>
        ))
      }
      </wc-stories>
    )
  }
}

Angular

If you’re using Angular, put the component inside your template. Like React, you can put the configuration inside the controller instead passing raw values:

<template>
  ...
  <wc-stories [width]="storiesWidth" [height]="storiesHeight" withShadow>
    <wc-stories-story *ngFor="let story of stories" [src]="story">
    </wc-stories-story>
  </wc-stories>
</template>

@Component({
  ...
})
class MyComponent implements OnInit {
  ngOnInit() {
    stories = [
      '/path/to/image',
      '/path/to/image',
      '/path/to/image',
      ...
    ]
  }
}

Vue

If you’re using Vue, put the component inside your template. Like React, you can put the configuration inside the controller instead passing raw values:

<wc-stories :width="storiesWidth" :height="storiesHeigh" :withShadow="withShadow">
  <wc-stories-story v-if="story of stories" :src="story"></wc-stories>
</wc-stories>

export default {
  data: () => ({
    width: 320,
    height: 480,
    withShadow: tre,
    stories: [
      '/path/to/image',
      '/path/to/image',
      '/path/to/image',
      ...
    ]
  })
}

🆕 Lazy Loading

There are several ways to lazy loading images like Low quality image placeholders and progressive images. This feature relies on the first one, so, in order to enable it, you need to pass, along with the images, the placeholders too.

Tip: you can generate lightweight svg LQIP from high resolution images using sqip.

<wc-stories height="667" width="375" withShadow>
  <wc-stories-story src="img/01.jpg" placeholder="img/01.ph.svg"></wc-stories-story>
  <wc-stories-story src="img/02.jpg" placeholder="img/02.ph.svg"></wc-stories-story>
  <wc-stories-story src="img/03.jpg" placeholder="img/03.ph.svg"></wc-stories-story>
  <wc-stories-story src="img/04.jpg" placeholder="img/04.ph.svg"></wc-stories-story>
  <wc-stories-story src="img/05.jpg" placeholder="img/05.ph.svg"></wc-stories-story>
</wc-stories>
