Json/Nodejs: How do I get specific data from a JSON file

I am trying to develop a discord bot with nodejs. My question is how do I get a specific data out of a JSON file (for instance, from this json. I want to only specify a single uuid like "59d4c622c7cc459a98c2e947054e2b11" and get the data.

The simple soln you can use filter. Best is use reduce.

const data = {
  guild: {
    _id: "5b2906070cf29ddccd0f203c",
    name: "Dulcet",
    coins: 122010,
    coinsEver: 232010,
    created: 1529415175560,
    members: [
      {
        uuid: "59d4c622c7cc459a98c2e947054e2b11",
        rank: "MEMBER",
        joined: 1529683128302,
        questParticipation: 39,
        expHistory: {
          "2020-02-16": 0,
          "2020-02-15": 0,
          "2020-02-14": 0,
          "2020-02-13": 0,
          "2020-02-12": 0,
          "2020-02-11": 0,
          "2020-02-10": 0
        }
      }
    ]
  }
};

const members = data.guild.members.filter(
  member => member.uuid == "59d4c622c7cc459a98c2e947054e2b11"
);

const firstMember = members[0]
console.log(firstMember)

Assuming you have already parsed the JSON into an actual Javascript object named data and given the way the data is currently organized, you would have to search the data.guild.members array to find the object that had the desired uuid property value.

function findDataForUuid(uuid) {
     for (let obj of data.guild.members) {
        if (obj.uuid === uuid) {
            return obj;
        }
     }
     // no match found
     return null;
}


let item = findDataForUuid("59d4c622c7cc459a98c2e947054e2b11");
if (item) {
    console.log(item);    // will show all the properties of the member object
}

Or, using .find() on the array:

function findDataForUuid(uuid) {
     return data.guild.members.find(item => {
         return item.uuid === uuid;
     });
}
