How to use the pouchdb-utils.parseUri function in pouchdb-utils

function getHost(name, opts) {
  // encode db name if opts.prefix is a url (#5574)
  if (hasUrlPrefix(opts)) {
    var dbName = opts.name.substr(opts.prefix.length);
    // Ensure prefix has a trailing slash
    var prefix = opts.prefix.replace(/\/?$/, '/');
    name = prefix + encodeURIComponent(dbName);
  }

  var uri = parseUri(name);
  if (uri.user || uri.password) {
    uri.auth = {username: uri.user, password: uri.password};
  }

  // Split the path part of the URI into parts using '/' as the delimiter
  // after removing any leading '/' and any trailing '/'
  var parts = uri.path.replace(/(^\/|\/$)/g, '').split('/');

  uri.db = parts.pop();
  // Prevent double encoding of URI component
  if (uri.db.indexOf('%') === -1) {
    uri.db = encodeURIComponent(uri.db);
  }

  uri.path = parts.join('/');

function hasUrlPrefix(opts) {
  if (!opts.prefix) {
    return false;
  }
  var protocol = parseUri(opts.prefix).protocol;
  return protocol === 'http' || protocol === 'https';
}
