<h3 id="step-1-setting-up-the-html-and-including-the-barcode-scanner">Step 1: Setting up the HTML and Including the Barcode Scanner</h3>
<p>As outlined earlier, this guide will help you create a simple Hello World barcode scanning application using vanilla JavaScript. The full sample code is also available in the <a href="https://github.com/Dynamsoft/barcode-reader-javascript-samples/tree/v10.5.30">GitHub repository</a>.</p>
<p>The first step before writing the code is to include the SDK in your application. You can simply include the SDK by using the precompiled script.</p>
<pre><code class="hljs html language-html"><span class="hljs-meta"><!DOCTYPE <span class="hljs-meta-keyword">html</span>></span>
<span class="hljs-tag"><<span class="hljs-name">html</span> <span class="hljs-attr">lang</span>=<span class="hljs-string">"en"</span>></span>
<span class="hljs-tag"><<span class="hljs-name">head</span>></span>
<span class="hljs-tag"><<span class="hljs-name">meta</span> <span class="hljs-attr">charset</span>=<span class="hljs-string">"utf-8"</span> /></span>
<span class="hljs-tag"><<span class="hljs-name">meta</span> <span class="hljs-attr">name</span>=<span class="hljs-string">"viewport"</span> <span class="hljs-attr">content</span>=<span class="hljs-string">"width=device-width, initial-scale=1.0"</span> /></span>

<span class="hljs-tag"><<span class="hljs-name">script</span> <span class="hljs-attr">src</span>=<span class="hljs-string">"https://cdn.jsdelivr.net/npm/dynamsoft-barcode-reader-bundle@10.5.3000/dist/dbr.bundle.js"</span>></span><span class="hljs-tag"></<span class="hljs-name">script</span>></span>
<span class="hljs-tag"></<span class="hljs-name">head</span>></span>
<span class="hljs-tag"><<span class="hljs-name">body</span>></span>
<span class="hljs-tag"><<span class="hljs-name">h1</span> <span class="hljs-attr">style</span>=<span class="hljs-string">"font-size: large"</span>></span>Dynamsoft Barcode Scanner<span class="hljs-tag"></<span class="hljs-name">h1</span>></span>
<span class="hljs-tag"></<span class="hljs-name">body</span>></span>
<span class="hljs-tag"></<span class="hljs-name">html</span>></span>
</code></pre>
<p>In this example, we include the precompiled Barcode Scanner SDK script via public CDN in the header.</p>
<div class="multi-panel-switching-prefix"></div>
<div class="multi-panel-start"></div>
<div class="multi-panel-title">Use a public CDN</div>
<p>The simplest way to include the SDK is to use either the <a href="https://jsdelivr.com/"><strong>jsDelivr</strong></a> or <a href="https://unpkg.com/"><strong>UNPKG</strong></a> CDN.</p>
<ul>
<li>jsDelivr</li>
</ul>
<pre><code class="hljs html language-html"> <span class="hljs-tag"><<span class="hljs-name">script</span> <span class="hljs-attr">src</span>=<span class="hljs-string">"https://cdn.jsdelivr.net/npm/dynamsoft-barcode-reader-bundle@10.5.3000/dist/dbr.bundle.js"</span>></span><span class="hljs-tag"></<span class="hljs-name">script</span>></span>
</code></pre>
<ul>
<li>UNPKG</li>
</ul>
<pre><code class="hljs html language-html"> <span class="hljs-tag"><<span class="hljs-name">script</span> <span class="hljs-attr">src</span>=<span class="hljs-string">"https://unpkg.com/dynamsoft-barcode-reader-bundle@10.5.3000/dist/dbr.bundle.js"</span>></span><span class="hljs-tag"></<span class="hljs-name">script</span>></span>
</code></pre>
<p>When using a framework such as <strong>React</strong>, <strong>Vue</strong> or <strong>Angular</strong>, we recommend adding the package as a dependency using a package manager such as <strong>npm</strong> or <strong>yarn</strong>:</p>
<pre><code class="hljs sh language-sh"> npm i dynamsoft-barcode-reader-bundle@10.5.3000
<span class="hljs-comment"># or</span>
yarn add dynamsoft-barcode-reader-bundle@10.5.3000
</code></pre>
<p>As for package managers like <strong>npm</strong> or <strong>yarn</strong>, you likely need to specify the location of the engine files as a link to a CDN. Please see the <a href="https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/barcode-scanner.html#barcodescannerconfig">BarcodeScannerConfig API</a> for a code snippet on how to set the <code>engineResourcePaths</code>.</p>
<div class="multi-panel-end"></div>
<div class="multi-panel-start"></div>
<div class="multi-panel-title">Host the SDK yourself</div>
<p>Alternatively, you may choose to download the SDK and host the files on your own server or preferred CDN. This approach provides better control over versioning and availability.</p>
<ul>
<li><p>From the website</p>
<p><a href="https://www.dynamsoft.com/barcode-reader/downloads/?ver=10.5.30&utm_source=npm&product=dbr&package=js">Download Dynamsoft Barcode Reader JavaScript Package</a></p>
<p>The resources are located at path <code>dynamsoft/distributables/</code>.</p></li>
<li><p>From npm</p></li>
</ul>
<pre><code class="hljs sh language-sh"> npm i dynamsoft-barcode-reader-bundle@10.5.3000
</code></pre>
<p>The resources are located at the path <code>node_modules/<pkg></code>, without <code>@<version></code>. You can copy it elsewhere and add <code>@<version></code> tag. One more thing to do is to <a href="https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/barcode-scanner.html#barcodescannerconfig">specify the engineResourcePaths</a> so that the SDK can correctly locate the resources.</p>
<blockquote>
<p>[!IMPORTANT]<br />
Since "node<em>modules" is reserved for Node.js dependencies, and in our case the package is used only as static resources, we recommend either renaming the "node</em>modules" folder or moving the "dynamsoft-" packages to a dedicated folder for static resources in your project to facilitate self-hosting.</p>
</blockquote>
<p>You can typically include SDK like this:</p>
<pre><code class="hljs html language-html"><span class="hljs-tag"><<span class="hljs-name">script</span> <span class="hljs-attr">src</span>=<span class="hljs-string">"path/to/dynamsoft-barcode-reader-bundle@10.5.3000/dist/dbr.bundle.js"</span>></span><span class="hljs-tag"></<span class="hljs-name">script</span>></span>
</code></pre>
<div class="multi-panel-end"></div>
<div class="multi-panel-switching-end"></div>
<p>Barcode Scanner comes with a <strong>Ready-to-Use UI</strong>. When the Barcode Scanner launches, it creates a container which it populates with the <strong>Ready-to-Use UI</strong>.</p>
<h3 id="step-2-initializing-the-barcode-scanner">Step 2: Initializing the Barcode Scanner</h3>
<pre><code class="hljs js language-js"><span class="hljs-comment">// Initialize the Dynamsoft Barcode Scanner</span>
<span class="hljs-keyword">const</span> Barcodescanner = <span class="hljs-keyword">new</span> Dynamsoft.BarcodeScanner({
<span class="hljs-comment">// Please don't forget to replace YOUR_LICENSE_KEY_HERE</span>
<span class="hljs-attr">license</span>: <span class="hljs-string">"YOUR_LICENSE_KEY_HERE"</span>,
});
</code></pre>
<p>This is the <strong>simplest</strong> way to initialize the Barcode Scanner. The configuration object must include a valid <strong>license</strong> key. Without it, the scanner will fail to launch and display an error. For help obtaining a license, see the <a href="#license">licensing</a> section.</p>
<blockquote>
<p>[!TIP]<br />
By default, the <code>BarcodeScanner</code> scans a single barcode at a time. However, it also supports a <code>MULTI_UNIQUE</code> scanning mode, which continuously scans and accumulates unique results in real time. You can enable this mode by modifying the <a href="https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/barcode-scanner.html#barcodescannerconfig"><code>BarcodeScannerConfig</code></a> as follows:</p>
</blockquote>
<pre><code class="hljs js language-js"><span class="hljs-comment">// Initialize the Dynamsoft Barcode Scanner in MULTI_UNIQUE mode</span>
<span class="hljs-keyword">const</span> barcodescanner = <span class="hljs-keyword">new</span> Dynamsoft.BarcodeScanner({
<span class="hljs-attr">license</span>: <span class="hljs-string">"YOUR_LICENSE_KEY_HERE"</span>,
<span class="hljs-attr">scanMode</span>: Dynamsoft.EnumScanMode.SM_MULTI_UNIQUE,
<span class="hljs-attr">showResultView</span>: <span class="hljs-literal">true</span>,
});
</code></pre>
<h3 id="step-3-launching-the-barcode-scanner">Step 3: Launching the Barcode Scanner</h3>
<pre><code class="hljs js language-js">(<span class="hljs-keyword">async</span> () => {
<span class="hljs-comment">// Launch the scanner and wait for the result</span>
<span class="hljs-keyword">const</span> result = <span class="hljs-keyword">await</span> barcodescanner.launch();
alert(result.barcodeResults[<span class="hljs-number">0</span>].text);
})();
</code></pre>
<p>Now that the Barcode Scanner has been initialized and configured, it is ready to be launched! Upon launch, the Barcode Scanner presents the main <strong><code>BarcodeScannerView</code></strong> UI in its container on the page, and is ready to start scanning. By default, we use the <code>SINGLE</code> scanning mode, which means only one decoding result will be included in the final result. In the code above, we directly alerted the successfully decoded barcode text on the page.</p>
<blockquote>
<p>[!NOTE]<br />
In the Hello World sample, after a successfully decoding process, the scanner closes and the user is met with an empty page. In order to open the scanner again, the user must refresh the page. You may choose to implement a more user-friendly behavior in a production environment, such as presenting the user with an option to re-open the Barcode Scanner upon closing it.</p>
