Installation

Install using npm

npm install @abslibs/mongoose-plugin

Usage

We can use this plugin with or without options.

Setup

const mongoose_plugin = require('@abslibs/mongoose-plugin');

const TestSchema = new Schema({
  name: String
});

// Apply on specific model.
// Can apply globally : eg: mongoose.plugin(mongoose_plugin, {})
TestSchema.plugin(mongoose_plugin, {
  paranoid: true,
  timestamps: true,
  createdAt: 'created_at',
  updatedAt: 'updated_at'
});

const Test = mongoose.model('Test', TestSchema);

Options

paranoid : it needs to be true for soft deletion.

timestamps : it will add [createdAt & updatedAt] in schema.

createdAt : can replace createdAt by given string. eg: createdAt: 'created_at'

updatedAt : can replace updatedAt by given string. eg: updatedAt: 'created_at'

Simple usage

const test = new Test({ name: 'Test' });
test.save(function() {
  test.destroy(function() {
    // deleted: true
    test.restore(function() {});
    //deleted: false
  });
});

var exampleTestId = mongoose.Types.ObjectId('53da93b16b4a6670076b16bf');

// INFO: Example usage of destroyById static method
Test.destroyById(exampleTestId, function(err, TestDocument) {});

Get sot soft deleted data.

// pass *{ paranoid: false }* as option.
// This will return response including deleted documents.
test.find({ name: 'Arpit' }, null, { paranoid: false }, (err, user) => {});

Who has deleted the data?

var mongoose_plugin = require('@abslibs/mongoose-plugin');

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

TestSchema.plugin(mongoose_plugin, { deletedBy: true });
var Test = mongoose.model('Test', TestSchema);
var test = new Test({ name: 'Test' });
test.save(function() {
  // mongodb: { deleted: false, name: 'Test' }

  var idUser = mongoose.Types.ObjectId('53da93b16b4a6670076b16bf');
  test.destroy(idUser, function() {
    // mongodb: { deleted: true, name: 'Test', deletedBy: ObjectId("53da93b16b4a6670076b16bf")}
    test.restore(function() {});
  });
});

Bulk destroy and restore

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

// destroy multiple object, callback
Test.destroy(function (err, result) { ... });
Test.destroy({age:10}, function (err, result) { ... });
Test.destroy({}, idUser, function (err, result) { ... });
Test.destroy({age:10}, idUser, function (err, result) { ... });

// destroy multiple object, promise
Test.destroy().exec(function (err, result) { ... });
Test.destroy({age:10}).exec(function (err, result) { ... });
Test.destroy({}, idUser).exec(function (err, result) { ... });
Test.destroy({age:10}, idUser).exec(function (err, result) { ... });

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

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

Create index on fields

TestSchema.plugin(mongoose_plugin, { indexFields: true });

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

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.

NOTE : Method will be overridden if paranoid is true

only not deleted documents
count()
find()
findOne()
findOneAndUpdate()
update()
