Features

Installation

Install using npm

npm install mongoose-delete

Usage

We can use this plugin with or without options.

Simple usage

var mongoose_delete = require('mongoose-delete');

var PetSchema = new Schema({
    name: String
});

PetSchema.plugin(mongoose_delete);

var Pet = mongoose.model('Pet', PetSchema);

var fluffy = new Pet({ name: 'Fluffy' });

fluffy.save(function () {
    // mongodb: { deleted: false, name: 'Fluffy' }

    // note: you should invoke exactly delete() method instead of standard fluffy.remove()
    fluffy.delete(function () {
        // mongodb: { deleted: true, name: 'Fluffy' }

        fluffy.restore(function () {
            // mongodb: { deleted: false, name: 'Fluffy' }
        });
    });

});

var examplePetId = mongoose.Types.ObjectId("53da93b16b4a6670076b16bf");

// INFO: Example usage of deleteById static method
Pet.deleteById(examplePetId, function (err, petDocument) {
    // mongodb: { deleted: true, name: 'Fluffy', _id: '53da93b1...' }
});

Save time of deletion

var mongoose_delete = require('mongoose-delete');

var PetSchema = new Schema({
    name: String
});

PetSchema.plugin(mongoose_delete, { deletedAt : true });

var Pet = mongoose.model('Pet', PetSchema);

var fluffy = new Pet({ name: 'Fluffy' });

fluffy.save(function () {
    // mongodb: { deleted: false, name: 'Fluffy' }

    // note: you should invoke exactly delete() method instead of standard fluffy.remove()
    fluffy.delete(function () {
        // mongodb: { deleted: true, name: 'Fluffy', deletedAt: ISODate("2014-08-01T10:34:53.171Z")}

        fluffy.restore(function () {
            // mongodb: { deleted: false, name: 'Fluffy' }
        });
    });

});

Who has deleted the data?

var mongoose_delete = require('mongoose-delete');

var PetSchema = new Schema({
    name: String
});

PetSchema.plugin(mongoose_delete, { deletedBy : true });

var Pet = mongoose.model('Pet', PetSchema);

var fluffy = new Pet({ name: 'Fluffy' });

fluffy.save(function () {
    // mongodb: { deleted: false, name: 'Fluffy' }

    var idUser = mongoose.Types.ObjectId("53da93b16b4a6670076b16bf");

    // note: you should invoke exactly delete() method instead of standard fluffy.remove()
    fluffy.delete(idUser, function () {
        // mongodb: { deleted: true, name: 'Fluffy', deletedBy: ObjectId("53da93b16b4a6670076b16bf")}

        fluffy.restore(function () {
            // mongodb: { deleted: false, name: 'Fluffy' }
        });
    });

});

Bulk delete and restore

var mongoose_delete = require('mongoose-delete');

var PetSchema = new Schema({
    name: String,
    age: Number
});

PetSchema.plugin(mongoose_delete);

var Pet = mongoose.model('Pet', PetSchema);

var idUser = mongoose.Types.ObjectId("53da93b16b4a6670076b16bf");

// Delete multiple object, callback
Pet.delete(function (err, result) { ... });
Pet.delete({age:10}, function (err, result) { ... });
Pet.delete({}, idUser, function (err, result) { ... });
Pet.delete({age:10}, idUser, function (err, result) { ... });

// Delete multiple object, promise
Pet.delete().exec(function (err, result) { ... });
Pet.delete({age:10}).exec(function (err, result) { ... });
Pet.delete({}, idUser).exec(function (err, result) { ... });
Pet.delete({age:10}, idUser).exec(function (err, result) { ... });

// Restore multiple object, callback
Pet.restore(function (err, result) { ... });
Pet.restore({age:10}, function (err, result) { ... });

// Restore multiple object, promise
Pet.restore().exec(function (err, result) { ... });
Pet.restore({age:10}).exec(function (err, result) { ... });

Method overridden

We have the option to override all standard methods or only specific methods. Overridden methods will exclude deleted documents from results, documents that have deleted = true. Every overridden method will have two additional methods, so we will be able to work with deleted documents.

only not deleted documents only deleted documents all documents
count() countDeleted countWithDeleted
find() findDeleted findWithDeleted
findOne() findOneDeleted findOneWithDeleted
findOneAndUpdate() findOneAndUpdateDeleted findOneAndUpdateWithDeleted
update() updateDeleted updateWithDeleted

Examples how to override one or multiple methods

var mongoose_delete = require('mongoose-delete');

var PetSchema = new Schema({
    name: String
});

// Override all methods
PetSchema.plugin(mongoose_delete, { overrideMethods: 'all' });
// or 
PetSchema.plugin(mongoose_delete, { overrideMethods: true });

// Overide only specific methods
PetSchema.plugin(mongoose_delete, { overrideMethods: ['count', 'find', 'findOne', 'findOneAndUpdate', 'update'] });
// or
PetSchema.plugin(mongoose_delete, { overrideMethods: ['count', 'countDocuments', 'find'] });
// or (unrecognized method names will be ignored)
PetSchema.plugin(mongoose_delete, { overrideMethods: ['count', 'find', 'errorXyz'] });


var Pet = mongoose.model('Pet', PetSchema);

// Example of usage overridden methods

Pet.find(function (err, documents) {
  // will return only NOT DELETED documents
});

Pet.findDeleted(function (err, documents) {
  // will return only DELETED documents
});

Pet.findWithDeleted(function (err, documents) {
  // will return ALL documents
});

Disable model validation on delete

var mongoose_delete = require('mongoose-delete');

var PetSchema = new Schema({
    name: { type: String, required: true }
});

// By default, validateBeforeDelete is set to true
PetSchema.plugin(mongoose_delete);
// the previous line is identical to next line
PetSchema.plugin(mongoose_delete, { validateBeforeDelete: true });

// To disable model validation on delete, set validateBeforeDelete option to false
PetSchema.plugin(mongoose_delete, { validateBeforeDelete: false });

// NOTE: This is based on existing Mongoose validateBeforeSave option
// http://mongoosejs.com/docs/guide.html#validateBeforeSave

Create index on fields

var mongoose_delete = require('mongoose-delete');

var PetSchema = new Schema({
    name: String
});

// Index all field related to plugin (deleted, deletedAt, deletedBy)
PetSchema.plugin(mongoose_delete, { indexFields: 'all' });
// or 
PetSchema.plugin(mongoose_delete, { indexFields: true });

// Index only specific fields
PetSchema.plugin(mongoose_delete, { indexFields: ['deleted', 'deletedBy'] });
// or
PetSchema.plugin(mongoose_delete, { indexFields: ['deletedAt'] });
