How do I set default value of an integer in mongodb?
As you're using Mongoose, you can set the default as part of the Schema definition:
var userSchema = new Schema({ win: { type: Number, default: 0 }});The options are documented here. It's also cool that if you set the default to a function, it will execute when the Model is instantiated. For example, if it were: default: Date.now, it will call the Date.now() function when a model is created.
