it looks like that the query function has a second parameter with a "params" array.

probably something like this would work then too (didn't test):

  return await query(
      `SELECT Owner, Aroma, Flavor, Acidity, Sweetness
         FROM coffee
         ORDER BY vec_distance_L2(
           embedding, '[?,?,?,?]')
         LIMIT 100`,
      [+aroma, +flavor, +acid, +sweet],
    );

it is nice because the query string is constant then and a prepared query could be cached..
