How to use the vue-inbrowser-compiler-utils.isCodeVueSfc function in vue-inbrowser-compiler-utils

const getScript = (code: string): string => {
		// if in JSX mode just parse code as is
		if (config.jsxInExamples) {
			return code
		}

		// script is at the beginning of a line after a return
		// In case we are loading a vue component as an example, extract script tag
		if (isCodeVueSfc(code)) {
			const parts = parseComponent(code)
			return parts && parts.script ? parts.script.content : ''
		}
		//else it could be the weird almost jsx of vue-styleguidist
		return code.split(/\n[\t ]*

function prepareVueCodeForEvalFunction(code: string, config: any): EvaluableComponent {
	let style,
		vsgMode = false,
		template

	// if the component is written as a Vue sfc,
	// transform it in to a "return"
	// even if jsx is used in an sfc we still use this use case
	if (isCodeVueSfc(code)) {
		return normalizeSfcComponent(code)
	}

	// if it's not a new Vue, it must be a simple template or a vsg format
	// lets separate the template from the script
	if (!/new Vue\(/.test(code)) {
		// this for jsx examples without the SFC shell
		// export default {render: (h) =&gt; <button>}
		if (config.jsx) {
			const { preprocessing, component, postprocessing } = parseScriptCode(code)
			return {
				script: `${preprocessing};\nreturn {${component}};\n${postprocessing}`
			}
		}

		const findStartTemplateMatch = /^\W*</button>
