Hi, I am using Node and Mongodb with mongoose. I am trying to output a list of dependencies. When i do a console log i get a dependencies list of objects that are called object. The command i am using outputs on the mongo cmd line but when i try to query it in node , and put a console log in my controller i get this. Anybody Know how to fix it ? Thanks in advance.

Answer 1

that's not contain problems with your code.
Try with
console.log(list_dependencies[0]);
If not work, just change from string to object like this
const result = JSON.parse(list_dependencies);
console.log(result)

Answer 2

MongoDB "find" query returns an array(list) of results.(you see a list of objects)
If you are are expecting only one result better use "findOne" query.
