Get Started with ActiveReportsJS Report Viewer in a Svelte.js application

Create Svelte application

The easiest way to create a Svelte application is to use the SvelteKit tool. Run the following command from the command prompt or terminal:

npm create svelte@latest arjs-svelte-viewer-app

It will ask several questions and below the list of recommended answers

┌  Welcome to SvelteKit!
│
◇  Which Svelte app template?
│  Skeleton project
│
◇  Add type checking with TypeScript?
│  Yes, using TypeScript syntax
│
◇  Select additional options (use arrow keys/space bar)
│  none
│
└  Your project is ready!

Once the command run successfully, you could open the newly created arjs-svelte-viewer-app in your favorite IDE, such as Visual Studio Code.

Install ActivereportsJS npm packages

We provide the Svelte Report Viewer Component through the @mescius/activereportsjs-svelte npm package. This package is built upon the foundational @mescius/activereportsjs package, which encompasses the core functionalities essential for the component's operation.

To install the latest version of the @mescius/activereportsjs-svelte package, along with its necessary dependencies, execute the command below from your application's root directory:

npm install @mescius/activereportsjs-svelte@latest
# or if you use yarn
yarn add @mescius/activereportsjs-svelte@latest 

Add ActiveReportsJS report to the application

ActiveReportsJS uses the JSON format and the rdlx-json extension for report template files.

In the static folder of the application, create a new file called report.rdlx-json and insert the following content into it.

{
  "Name": "Report",
  "Body": {
    "ReportItems": [
      {
        "Type": "textbox",
        "Name": "TextBox1",
        "Value": "Hello, ActiveReportsJS Viewer",
        "Style": {
          "FontSize": "18pt",
          "PaddingLeft": "5pt",
          "PaddingTop": "5pt"          
        },
        "Width": "8.5in",
        "Height": "0.5in"
      }
    ]
  }
}

Add Report Viewer component to the application

Replace the default content of the src\routes\+page.svelte file with the following code

<script lang="ts">
    import '@mescius/activereportsjs/styles/ar-js-ui.css';
    import '@mescius/activereportsjs/styles/ar-js-viewer.css';
    import {Viewer} from "@mescius/activereportsjs-svelte";
</script>

<div id="viewer-host">
    <Viewer report = {{ Uri: 'report.rdlx-json' }}></Viewer>
</div>

<style>
    #viewer-host {
        width: 100%;
        height: 100vh;
    }
</style>

Disable server-side rendering

By default, SvelteKit will render any page first on the server and send it to the client as HTML. But ActiveReportsJS can only operate on the client-side. Hence, we need to disable the server-side rendering for the page that contains the Report Viewer. We can do that by adding the +page.js file with the following content alongside the +page.svelte

export const prerender = false;
export const ssr = false;

Run and test the application

You can run the application by using the yarn run dev or npm run dev commands. By default, the project runs at http://localhost:5173/.

If you browse this URL, the ActiveReportsJS Report Viewer will appear on the page. The viewer will display the report that shows the Hello, ActiveReportsJS Viewer text. You can test the basic functionality by using the Report Viewer User Interface. The Report Viewer component exposes a rich API supplied with TypeScript declarations, so you can easily use it within a Svelte application.
