<blockquote>
|

<p><strong>Data URLs</strong>, URLs prefixed with the <code>data:</code> scheme, allow content creators to embed small files inline in documents.</p>
|
||
<p>— <a href=https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URLs target=_blank rel="noopener noreferrer">MDN</a></p>
|
||
</blockquote>
|
||
<p>Sometimes, you need to use an external file (e.g. script, stylesheet) that is not hosted online. In this case, you can use data URLs to embed the file in your code. These can then be used similar to regular URLs (e.g. for <code><script src></code>, <code><link href></code>, import URL, etc.).</p>
|
||
<p>LiveCodes UI allows creating and consuming these data URLs.</p>
|
||
<h2 class="anchor anchorWithStickyNavbar_LWe7" id=creating-data-urls>Creating data URLs<a href=#creating-data-urls class=hash-link aria-label="Direct link to Creating data URLs" title="Direct link to Creating data URLs"></a></h2>
|
||
<p>Data URLs can be created from:</p>
|
||
<h3 class="anchor anchorWithStickyNavbar_LWe7" id=assets>Assets<a href=#assets class=hash-link aria-label="Direct link to Assets" title="Direct link to Assets"></a></h3>
|
||
<p>For local files on user's device.</p>
|
||
<p><a href=/docs/features/assets>Assets screen</a> can be accessed from Settings menu → Assets. This works for any file type, including text files (e.g. stylesheets or scripts) and binary files like images. Generated data URLs are saved locally in the user's browser storage and are available across projects.</p>
|
||
<h3 class="anchor anchorWithStickyNavbar_LWe7" id=copy-code-as-data-url-button>"Copy code as data URL" button<a href=#copy-code-as-data-url-button class=hash-link aria-label='Direct link to "Copy code as data URL" button' title='Direct link to "Copy code as data URL" button'></a></h3>
|
||
<p>For code in code editor.</p>
|
||
<p>The button can be found in the editor toolbar, below the code editor. This copies the code of the active editor as data URL to the clipboard.</p>
|
||
<p>The content is base64-encoded. Unicode content is appropriately encoded (see <a href=https://developer.mozilla.org/en-US/docs/Glossary/Base64#the_unicode_problem target=_blank rel="noopener noreferrer">The "Unicode Problem"</a>).</p>
|
||
<h2 class="anchor anchorWithStickyNavbar_LWe7" id=consuming-data-urls>Consuming data URLs<a href=#consuming-data-urls class=hash-link aria-label="Direct link to Consuming data URLs" title="Direct link to Consuming data URLs"></a></h2>
|
||
<p>Data URLs can be used anywhere you use a regular URL (e.g. for <code><script src></code>, <code><link href></code>, import URL, etc.).</p>
|
||
<p>In addition, LiveCodes supports <a href=/docs/features/import>importing</a> data URLs, like other URLs. If the language is detected, it is loaded in the appropriate editor (e.g. <code>data:text/typescript;charset=UTF-8;base64,....</code> is detected as TypeScript).</p>
