how to take screenshot or screen video in angular 5

I am using angular 5 sample project, want to build feature for screenshot or capture screen video using angular5 component structure.

For Screenshot, this library should do the trick.

npm install angular-screenshot

Basic usage example: Use screenshot as element or attribute, then use default template and cover children elements default

    <button class="btn btn-fab" ng-class="{true: 'btn-danger', false: 'btn-default'}
[appCtrl.isBasicOpen]" ng-click="appCtrl.isBasicOpen = !appCtrl.isBasicOpen">
    <i ng-if="!appCtrl.isBasicOpen" class="material-icons">crop</i>
    <i ng-if="appCtrl.isBasicOpen" class="material-icons">close</i>
</button>
<!--screenshot-->
<screenshot is-open="appCtrl.isBasicOpen">
    <div class="panel-body">
        ...
    </div>
</screenshot>

Use target parameter to set screenshot section on element

<div id="target1" class="panel panel-info">
    ...
    <div class="panel-body">
        <screenshot target="{{::'#target1'}}" is-open="appCtrl.target1Open" toolbox-options="appCtrl.target1Options"></screenshot>
            ...
    </div>
</div>

'use strict';
(function () {
angular.module('app', ['angular-screenshot'])
.controller('AppController', ['$scope', appController]);
    function appController($scope) {
        var self = this;
        self.target1Options = {
            filename: 'target1.png',
            downloadText: 'Download me',
            cancelText: 'Close it!'
        };
    }
})()
