soft-delete-mongoose-plugin v1.1.3

soft-delete-mongoose-plugin

A simple and friendly soft delete plugin for mongoose，implementation using TS.

Methods were added and overridden on mongoose model to realize soft deletion logic.

Features

• Soft delete data using soft delete flag and date markers is friendly for scenarios where a unique index needs to be created
• User-defined soft delete field names are supported
• Add independent soft delete methods to the mongoose model, all hard delete methods are retained completely
• Rewrite all query and update methods on mongoose Model and automatically inject soft delete filtering conditions; If the user filter contains any queries related to soft delete fields, the program will assume that the user needs to have full control of the data and will not automatically inject soft delete filtering conditions

Quick Start

Install

$ npm install soft-delete-mongoose-plugin

Usage

Typescript

Use of the SoftDeleteModel type, instead of the Model type.

import { set, Schema, model, connect, connection, plugin } from 'mongoose';
import { SoftDelete, SoftDeleteModel } from 'soft-delete-mongoose-plugin';

async function main() {
  set('debug', true);

  await connect('mongodb://localhost:27017/test?directConnection=true');

  // defind soft delete field name
  const IS_DELETED_FIELD = 'isDeleted';
  const DELETED_AT_FIELD = 'deletedAt';

  // use soft delete plugin
  plugin(
    new SoftDelete({
      isDeletedField: IS_DELETED_FIELD,
      deletedAtField: DELETED_AT_FIELD,
    }).getPlugin(),
  );

  interface ISoftDelete {
    [IS_DELETED_FIELD]: boolean;
    [DELETED_AT_FIELD]: Date | null;
  }

  interface IPerson extends ISoftDelete {
    name: string;
  }

  const personSchema = new Schema<IPerson>({
    name: { type: String, required: true },
    isDeleted: { type: Boolean, default: false },
    deletedAt: { type: Date, default: null },
  });

  // use of the SoftDeleteModel type, instead of the Model type.
  const personModel = model<IPerson, SoftDeleteModel<IPerson>>(
    'persons',
    personSchema,
  );

  // It's ready to use studentModel to soft delete documents
  await personModel.softDeleteMany();

  await connection.close();
}

main();

JavaScript

const { set, Schema, model, connect, connection, plugin } = require('mongoose');
const { SoftDelete } = require('soft-delete-mongoose-plugin');

async function main() {
  set('debug', true);

  await connect('mongodb://localhost:27017/test?directConnection=true');

  // defind soft delete field name
  const IS_DELETED_FIELD = 'isDeleted';
  const DELETED_AT_FIELD = 'deletedAt';

  // use soft delete plugin
  plugin(
    new SoftDelete({
      isDeletedField: IS_DELETED_FIELD,
      deletedAtField: DELETED_AT_FIELD,
    }).getPlugin(),
  );

  const personSchema = new Schema({
    name: { type: String, required: true },
    isDeleted: { type: Boolean, default: false },
    deletedAt: { type: Date, default: null },
  });

  // use of the SoftDeleteModel type, instead of the Model type.
  const personModel = model('persons', personSchema);

  // It's ready to use studentModel to soft delete documents
  await personModel.softDeleteMany();

  await connection.close();
}

main();

API

Class: SoftDelete

Parameters：

• options \<Object>

  isDeletedField \<string> Soft delete flag field name, field type: boolean

  deletedAtField \<string> Soft delete date field name, field type: Date | null

  mongoDBVersion? \<string> Rewrite with better query statements based on the mongoDB version used, default the last MongoDB version

  override \<OverrideOptions> Sets whether the specified method needs to be overridden

Overridden model methods are supported by default：

aggregate, bulkWrite, count, countDocuments, distinct, exists, find, findOne, findOneAndReplace, findOneAndUpdate, replaceOne, update, updateMany, updateOne

Example usage:

new SoftDelete({
  isDeletedField: 'isDeleted',
  deletedAtField: 'deletedAt',
  mongoDBVersion: "5.0.5",
  override: { aggregate: false }, // not override aggregate method
});

Method: softDelete.getPlugin

return \<Function> The mongoose plugin function

Soft delete methods

Add independent soft delete methods to the mongoose model, the soft delete method actually calls the corresponding mongoose model update method：

These functions take the same parameters as the corresponding update methods, except that the update option parameters are automatically replaced with soft delete field updates.
