+import {
+  formatDecodal,
+  formatDecodalCommand,
+  initDecodalFormatter,
+} from 'decodal-codemirror/format';
+import formatterWasm from 'decodal-codemirror/wasm/decodal_language_tools_bg.wasm?url';

+const result = formatDecodal('Server={port=Int default 8080;};');
+if (result.ok) console.log(result.source);
