如何使用mongoose调用MongoDB数组

npm install mongoose

const mongoose = require('mongoose');

mongoose.connect('mongodb://localhost/mydatabase', { useNewUrlParser: true, useUnifiedTopology: true })
  .then(() => {
    console.log('Connected to MongoDB');
  })
  .catch((error) => {
    console.error('Error connecting to MongoDB', error);
  });

const schema = new mongoose.Schema({
  name: String,
  arrayField: [String]
});

const Model = mongoose.model('Model', schema);

Model.find({ arrayField: 'element' })
  .then((documents) => {
    console.log(documents);
  })
  .catch((error) => {
    console.error(error);
  });

Model.updateOne({ _id: documentId }, { $push: { arrayField: 'newElement' } })
  .then(() => {
    console.log('Array updated successfully');
  })
  .catch((error) => {
    console.error(error);
  });

Model.updateOne({ _id: documentId }, { $pull: { arrayField: 'elementToDelete' } })
  .then(() => {
    console.log('Array element deleted successfully');
  })
  .catch((error) => {
    console.error(error);
  });
