reactjs-epg v1.2.0

ReactJS EPG ( Electronic Programme Guide ) Component

It makes use of standard HTML elements ( divs ) to render data

Background

Live Streaming web portals, STB and browsers on mobile devices requires some form of EPG ( Electronic Programme Guide) to render channels and schedules. This is optimized based on recommendations to force web browsers to promote this component to take adavantage of GPU for performance.

Components are rendered based on ems for responsiveness. It's easy to customize for mobile devices by applying media-queries to containers in which the EPG is rendered and set different font-sizes based on the breakpoints or form factors.

For issues/bugs, meanwhile I open source this library, please report any bugs to vimalmadhav88@gmail.com

Future Release

• Support for paginated scrolling to include multiple days of EPG
• Render in chunks for better UX by reducing time to first meaningful paint / first contentful paint

Sample

import EPG from "reactjs-epg";

const getStartTime = (programme) => {
  const start = programme.startTime;
  const end = programme.endTime;
  return `${new Date(start).getHours()}:${new Date(start).getMinutes()}-${new Date(end).getHours()}:${new Date(end).getMinutes()}`;
};

const epgData = (chs) => {
  return chs.filter((ch) => {
    return schedules.some((schedule) => schedule.channelId === ch.channelID);
  });
};

export default function App() {
  const channels = epgData(channels.channels);
  const settings = {
    EPGClass: "epg",
    ChannelListClass: "channel-list",
    ChannelIconClass: "channel",
    ProgammeClass: "programme",
    TimeScaleClass: "time-scale",
    TimeScaleStampClass: "current-time",
    TimeScaleSeparatorClass: "separator",
    CurrentProgrammeClass: "current-program",
  };
  return (
    <div className="App">
      <div className="container">
        <EPG
          schedules={schedules}
          channels={channels}
          onSelected={(e, item) => console.log(e, item)}
          settings={settings}
          renderItem={(data) => {
            return (
              <>
                <div>{data.title}</div>
                <div>{getStartTime(data)}</div>
              </>
            );
          }}
        />
      </div>
    </div>
  );
}

Props

Note: Keep the channels and schedules of same length
