title: Storing Json Object in Mongoose String key
body: <p>In my Mongoose schema, I have a field which is a String, and I want to be able to store an JSON object in it. Is it possible? In Postgres, it's possible to store a dictionary in a string column. </p>
  
  <p>I want to do that because the dictionary (actually a JSON object in JS) is just a simple read and write value and doesn't need queries, but also, because it is just one value and not an array of values.</p>
