Description

The HTML5 Report Viewer and Web Report Designer are built upon HTML5, CSS, and JavaScript. This allows using them in virtually any JavaScript framework including Vue.js.

The solution we are about to examine is a very basic approach to create a new Vue application, include the viewer and designer dependencies, and display them in separate views.

Solution

The following guide assumes previous knowledge of Vue:

Start by creating a new Vue application using the following CLI command:
- PowerShell
```
npm init vue@latest
```

Next, include the necessary JS dependencies of the viewer and designer in index.html. This includes the jQuery library, Kendo. For this example, we will be retrieving the Report Viewer and Report Designer JS resources from the online demos:

HTML

<body>
    <div id="app"></div>
    <script src="https://code.jquery.com/jquery-3.2.1.min.js"></script>
    <script src="https://kendo.cdn.telerik.com/2022.3.913/js/kendo.all.min.js"></script>
    <script src="https://demos.telerik.com/reporting/api/reports/resources/js/telerikReportViewer"></script>
    <script src="https://demos.telerik.com/reporting/api/reportdesigner/designerresources/js/webReportDesigner"></script>
    <script type="module" src="/src/main.js"></script>
</body>

Then, add the default Kendo SASS theme again in index.html, inside the head element, to style the report viewer and designer:
- HTML
```
<link rel="stylesheet" href="https://kendo.cdn.telerik.com/themes/5.9.0/default/default-main.css" />
```

Create a new report viewer component(e.g. ReportViewer.vue) and configure the routes accordingly. The new component contains a div element to hold the report viewer object and applies CSS to this element. The component calls the telerik_ReportViewer method to create the report viewer with the specified configuration options. It is important that the serviceUrl option points to the URL of a working Reporting REST Service:

HTML

<template>
    <div class="hello">
        <h1></h1>
        <div id="reportViewer1">loading...</div>
    </div>
</template>

<script>
    export default {
        name: 'ReportViewer',
        data () {
        return {
            msg: 'Welcome to Your Vue.js App'
        }
    },
    mounted () {
        this.$nextTick(function () {
            $('#reportViewer1')
            .telerik_ReportViewer({
                serviceUrl: 'http://demos.telerik.com/reporting/api/reports/',
                reportSource: {
                report: 'Dashboard.trdx'
                },
                viewMode: telerikReportViewer.ViewModes.INTERACTIVE,
                scaleMode: telerikReportViewer.ScaleModes.SPECIFIC,
                scale: 1.0,
                sendEmail: { enabled: true }
                })
            })
        }
    }
</script>

<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>
    #reportViewer1 {
        position: relative;
        width: 80vw;
        height: 1000px;
    }
</style>

Create a new report designer component((e.g. ReportDesigner.vue)) and configure the routes accordingly. The new component contains a div element to hold the report designer object and applies CSS to this element. The component calls the telerik_WebReportDesigner method to create the report viewer with the specified configuration options. It is important that the serviceUrl option points to the URL of a working Report Designer REST Service.

HTML

<template>
    <div id="wrd1">...</div>
</template>

<script>
    export default {
    name: "WebReportDesigner",
    mounted() {
        this.$nextTick(function () {
        $("#wrd1")
            .telerik_WebReportDesigner({
            toolboxArea: {
                layout: "list", //Change to "grid" to display the contents of the Components area in a flow grid layout.
            },
            serviceUrl: "https://demos.telerik.com/reporting/api/reportdesigner/",
            report: "Barcodes Report.trdx",
            })
            .data("telerik_WebDesigner");
        });
    },
};
</script>

<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>
    #wrd1 {
    position: relative;
    width: 100%;
    height: 880px;
    }
</style>

Run the dev script to start the application in development mode:
- PowerShell
```
npm run dev
```

Here is how the starting page of the application should look like:
