By default Dashboards.JS runs in trial mode with a watermark; registering your license key removes it.

In Vue.
<script setup lang="ts">
import { Viewer, Stimulsoft } from 'stimulsoft-dashboards-js-vuejs/viewer'

// Register your license from JavaScript code
// Stimulsoft.Base.StiLicense.key = "6vJhGtLLLz2GNviWmUTrhSqnO...";
// Stimulsoft.Base.StiLicense.loadFromFile("stimulsoft.key");

var report = new Stimulsoft.Report.StiReport();
report.loadFile("Dashboards/Dashboard.mrt");
</script>

<template>
    <Viewer :report="report" />
</template>

How it works. The license is registered before any component is created, so every dashboard renders without the trial watermark.
