Mongoose Delete Plugin

@npmteam2024/praesentium-itaque-inventore is simple and lightweight plugin that enables soft deletion of documents in MongoDB. This code is based on riyadhalnur's plugin mongoose-softdelete.

Features

• Add delete() method on document (do not override standard remove() method)
• Add deleteById() static method
• Add deleted (true-false) key on document
• Add deletedAt key to store time of deletion
• Add deletedBy key to record who deleted document
• Restore deleted documents using restore method
• Bulk delete and restore
• Option to override static methods (count, countDocuments, find, findOne, findOneAndUpdate, update, updateOne, updateMany)
• For overridden methods we have two additional methods: methodDeleted and methodWithDeleted
• Disable model validation on delete
• Disable model validation on restore
• Option to create index on delete fields (deleted, deletedAt, deletedBy)
• Option to disable use of $ne operator using {use$neOperator: false}. Before you start to use this option please check #50.
• Option to override aggregate.
• Option to populate with deleted documents ({ withDeleted: true })

Installation

Install using npm

npm install @npmteam2024/praesentium-itaque-inventore

TypeScript support

The plugin currently does not have its own type definition. Please be free to use @types/@npmteam2024/praesentium-itaque-inventore.

In doing so, you should make use of the SoftDeleteModel type, instead of the Model type.

import { Schema, model, connect } from 'mongoose';
import { SoftDeleteModel }, MongooseDelete from '@npmteam2024/praesentium-itaque-inventore';

interface Pet extends SoftDeleteDocument {
  name: string;
}

const PetSchema = new Schema<Pet>({
    name: String
});

PetSchema.plugin(MongooseDelete, { deletedBy: true, deletedByType: String });

const model: SoftDeleteModel = model<Pet>('Pet', PetSchema);

export default model;

Usage

We can use this plugin with or without options.

Simple usage

var mongoose_delete = require('@npmteam2024/praesentium-itaque-inventore');

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('@npmteam2024/praesentium-itaque-inventore');

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('@npmteam2024/praesentium-itaque-inventore');

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' }
        });
    });

});

The type for deletedBy does not have to be ObjectId, you can set a custom type, such as String.

var mongoose_delete = require('@npmteam2024/praesentium-itaque-inventore');

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

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

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

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

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

    var idUser = "my-custom-user-id";

    // note: you should invoke exactly delete() method instead of standard fluffy.remove()
    fluffy.delete(idUser, function () {
        // mongodb: { deleted: true, name: 'Fluffy', deletedBy: 'my-custom-user-id' }

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

Bulk delete and restore

var mongoose_delete = require('@npmteam2024/praesentium-itaque-inventore');

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 | | countDocuments() | countDocumentsDeleted | countDocumentsWithDeleted | | find() | findDeleted | findWithDeleted | | findOne() | findOneDeleted | findOneWithDeleted | | findOneAndUpdate() | findOneAndUpdateDeleted | findOneAndUpdateWithDeleted | | update() | updateDeleted | updateWithDeleted | | updateOne() | updateOneDeleted | updateOneWithDeleted | | updateMany() | updateManyDeleted | updateManyWithDeleted | | aggregate() | aggregateDeleted | aggregateWithDeleted | | findById() | Please use findOne | Please use findOneWithDeleted | | findByIdAndUpdate() | Please use findOneAndUpdateDeleted | Please use findOneAndUpdateWithDeleted |

Examples how to override one or multiple methods

var mongoose_delete = require('@npmteam2024/praesentium-itaque-inventore');

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('@npmteam2024/praesentium-itaque-inventore');

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

Disable model validation on restore

var mongoose_delete = require('@npmteam2024/praesentium-itaque-inventore');

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

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

// To disable model validation on restore, set validateBeforeRestore option to false
PetSchema.plugin(mongoose_delete, { validateBeforeRestore: 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('@npmteam2024/praesentium-itaque-inventore');

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'] });
