if (!el) {
el = document.createElement('meta');
el.setAttribute('name', name);
document.head.appendChild(el);
}
el.setAttribute('content', content);
}

export function setOgTag(property: string, content: string): void {
let el = document.querySelector('meta[property=' + JSON.stringify(property) + ']');
if (!el) {
el = document.createElement('meta');
el.setAttribute('property', property);
document.head.appendChild(el);
}
el.setAttribute('content', content);
}

export function setPageMeta(title: string, description: string): void {
document.title = title;
setMetaTag('description', description);
setOgTag('og:title', title);
setOgTag('og:description', description);
