Mongoose static methods:

Create

• Model.create(data)
• Model.insertMany(arr)

Read

• Model.find()
  • find all documents in a collection
  • note: returns an array (even if there's zero or one documents)
• Model.find(filter)
  • find all documents that match the filter.
  • ex: Model.find({price: {$gt: 20} })
• Model.findOne(filter)
• Model.findById(id)

Update

• Model.updateMany(filter, update [, options])
• Model.findOneAndUpdate(filter, update [, options])
• Model.findByIdAndUpdate(id, update [, options])
  • By default, it will return the document before the update was applied.
  • In case you want to receive the updated document, you can pass a third argument with { new: true }.
  • Example: Model.findByIdAndUpdate(id, update, { new: true })

Delete

• Model.deleteMany(filter)
• Model.deleteOne(filter)
• Model.findByIdAndDelete(id)
