Can anyone explain the difference with example.

Answer 1

Database logic should be encapsulated within the data model. Mongoose provides 2 ways of doing this, methods and statics. Methods adds an instance method to documents whereas Statics adds static "class" methods to the Models itself.

Given the example Animal Model below:

var AnimalSchema = mongoose.Schema({
  name: String,
  type: String,
  hasTail: Boolean
});

module.exports = mongoose.model('Animal', AnimalSchema);
