Angular - ngx-translate - Checking if translate key exist with Angular

Since I found no way to safely check for the presence of a translation, the best thing I could do is to check for equality synchronously:

hasTranslation(key: string): boolean {
  const translation = this.translateService.instant(key);
  return translation !== key && translation !== '';
}

However, I filed an issue with ngx-translate, asking for an official check method.

So, for your template you could just test with hasTranslation(x) ? ... : ...
