I have a document which has a field as Array of References and it is refering to the same document. I want to populate all the nested fields.

The Data will be Acyclic (person -> children -> children ≠ person).

The Schema of the Document look like

const personSchema = new mongoose.schema({
  name: {
    type: String,
    required: true,
  },
  [...],
  children: [{
    type: mongoose.Schema.Types.ObjectId,
    ref: "Person",
  }],
});

const Person = mongoose.model("Person", personSchema); 

while finding a person with his/her _id I want that it’s children, children’s children, …. must be populated

Output should look like

{
  "_id": 1,
  "name": "John Doe",
  "children": [
    {
      "_id": 2,
      "name": "Jane Doe",
      "children": [
        {
          "_id": 3,
          "name": "Billy Doe",
          "children": [
            {
              "_id": 4,
              "name": "Bobby Doe"
              [...]
            }
          ]
        }
      ]
    }
  ]
}
