Get all strings from array in mongoDb

December 10, 2022

I am a beginner in node and mongoDb. I send a models from the application to node.

const { users } = req.body;

console.log(users);

and when I print this I have this result.

[
  '{"id":"6389f4206f784a8e3d75cf10","email":"test5@test.com","password":"$2a$08$2cE5XFlShV0nBYS6JF4ckuRLcEvp75YuCazQLSyIZ6bKu5kev/dwS","verify":1,"invitationsToMe":["6390a3b8cb716fa4d67d82d6"],"invitationsFromMe":[],"friendsList":["638777339b32b61a57e5ab4b","638889b46b30846785db55df","638776e89b32b61a57e5ab43","638797306307ba909c43be22"],"username":"Przemek"}',

]

Now i want to extract from each "id" number to save in array in mondoDb. I found only .find( with filters ) but it not working for me.

>Solution :

const strings = [
  '{"id":"6389f4206f784a8e3d75cf10","email":"test5@test.com","password":"$2a$08$2cE5XFlShV0nBYS6JF4ckuRLcEvp75YuCazQLSyIZ6bKu5kev/dwS","verify":1,"invitationsToMe":["6390a3b8cb716fa4d67d82d6"],"invitationsFromMe":[],"friendsList":["638777339b32b61a57e5ab4b","638889b46b30846785db55df","638776e89b32b61a57e5ab43","638797306307ba909c43be22"],"username":"Przemek"}',

]

const objects = strings.map(str => JSON.parse(str))

console.log(objects)
