<p><a href=https://gleam.run target=_blank rel="noopener noreferrer">Gleam</a> is a friendly language for building type-safe systems that scale!</p>
<p>Gleam is a statically-typed functional programming language, which compiles to Erlang or JavaScript.</p>
<h2 class="anchor anchorWithStickyNavbar_LWe7" id=usage>Usage<a href=#usage class=hash-link aria-label="Direct link to Usage" title="Direct link to Usage">​</a></h2>
<p>LiveCodes compiles Gleam code to JavaScript using the WebAssembly (wasm) version of the <a href=https://github.com/gleam-lang/gleam target=_blank rel="noopener noreferrer">official Gleam compiler</a>. The compiled JavaScript code is then executed in the context of the <a href=/docs/features/result>result page</a>.</p>
<p>The compiled JavaScript code can be inspected in the <a href=/docs/features/compiled-code>Compiled Code Viewer</a> in the <a href=/docs/features/tools-pane>Tools Pane</a> (below the result page). Console output is shown in the <a href=/docs/features/console>integrated console</a>.</p>
<p>Please note that the compiler messages (e.g. errors and warnings) are shown in the browser console (not the integrated console).</p>

<h3 class="anchor anchorWithStickyNavbar_LWe7" id=custom-modules>Custom Modules<a href=#custom-modules class=hash-link aria-label="Direct link to Custom Modules" title="Direct link to Custom Modules">​</a></h3>
<p>Custom modules can be used in Gleam code. These modules have to be precompiled (to JavaScript) by the Gleam compiler. URLs to the compiled JavaScript code and either the Gleam source code or URLs to the Gleam source code are needed to be able to import custom modules.</p>
<p>This is an example for a repo with precompiled Gleam modules:
<a href=https://github.com/live-codes/gleam-precompiled target=_blank rel="noopener noreferrer">https://github.com/live-codes/gleam-precompiled</a></p>
<p>Please refer to <a href=https://gleam.run/writing-gleam/command-line-reference/ target=_blank rel="noopener noreferrer">Gleam CLI docs</a> for details about adding and building packages.</p>
<p>Note that the built code was committed to the repo by clearing out <code>.gitignore</code> file.</p>
<p>The built code can then by accessed from a <a href="https://www.jsdelivr.com/?docs=gh" target=_blank rel="noopener noreferrer">CDN that mirrors GitHub</a>, like this:
<code>https://cdn.jsdelivr.net/gh/live-codes/gleam-precompiled@main/...</code></p>
<p>Built modules can then be declared in <a href=/docs/advanced/custom-settings>custom settings</a> (Project menu → Custom Settings), under the <code>gleam</code> property, by adding a <code>modules</code> property.</p>
<p>The <code>modules</code> property is an object that has the module name as the key. The value is an object with the following properties:</p>
<ul>
<li><code>srcUrl</code>: the URL to the Gleam source code of the module.</li>
<li><code>src</code>: optionally use this instead of <code>srcUrl</code> to specify the Gleam source code of the module.</li>
<li><code>compiledUrl</code>: the URL to the compiled JavaScript code of the module.</li>
</ul>
<p>Example:</p>

<p>See the <a href=#example-usage>demo below</a> (<a href="https://livecodes.io/?template=gleam" target=_blank rel="noopener noreferrer">open in LiveCodes</a>).</p>
<p>If <code>compiledUrl</code> property is not specified, the JavaScript module is imported from this URL pattern: <code>{module_name}.mjs</code> (example: <code>plinth/browser/document.mjs</code>).
This can then be <a href=/docs/features/module-resolution#custom-module-resolution>mapped (using import maps)</a> in <a href=/docs/advanced/custom-settings>custom settings</a> (Project menu → Custom Settings) to the full URL of the compiled JavaScript code.</p>
