{{#each languages}}
<li><button onclick="window.location.href='/{{this.langcode}}';" class="btn btn-link btn-block language-select" type="button" name="VN"><img src="/images/{{this.langcode}}.png" alt="{{this.langname}}" title="{{this.langname}}" /> {{this.langname}}</button></li>
{{/each}}

<div id="language" class="btn-group">

                        <button class="btn-link dropdown-toggle" data-toggle="dropdown"> <span> <img src="/images/{{language}}.png" alt="Việt Nam" title="Việt Nam">{{langname}} <i class="fa fa-caret-down"></i></span></button>

                    </div>

erm, I think the easiest way is adding those to your translations like

en.json

{
    "en": "english",
    "de": "german"
}

de.json

{
    "en": "Englisch",
    "de": "Deutsch"
}

and using i18n helper to display (example in hbs)

{{#each languages}}
    <a href="/{{this}}">{{@root.__ this}}</a>
{{/each}}

[mashpie]

use i18n.getLocales() https://github.com/mashpie/i18n-node#i18ngetlocales and pass the result to locals of your view.

for one view only

app.get('/setlanguage', (req, res) => {
  res.render('languagesetting', {
    languages: i18n.getLocales()
  });
});

or more generally for all view by middleware

app.use((req, res, next) => {
  res.locals.languages: i18n.getLocales();
  next();
});
