How to set common property across all schema in Mongoose?

In my project I have multiple mongoose schema. The requirement is to add new property across all the schema. I want to avoid copy paste same thing across all schema. Looking for an alternative.

Thanks

Achieved the above requirement, sharing common property across the schema, (extending the schema). Following are the steps,

Created an object with all common property, example,

var baseProperty = {
    deleted     :   Boolean
    createdBy   :   String,
    updatedBy   :   String,
    createdAt   :   Date,
    updatedAt   :   Date,
};

then used in different schema in following way,

/** SCHEMA 1 **/ 
var userSchema = new Schema({
    name    :   String,
    mobile  :   String,
    email   :   String,
}, {});
userSchema.add(baseProperty);      // Injecting common property in schema
mongoose.model("User", userSchema); 


/** SCHEMA 2 **/
var addressSchema = new Schema({
    city    :   String,
    state   :   String,
    country   : String,
}, {});
addressSchema.add(baseProperty);  // Injecting common property in schema
mongoose.model("Address", addressSchema);

Now the above schema is ready with injected property, for CRUD operations.
