@automapper/sequelize

This is the official plugin from @automapper to work with Sequelize enabled projects. sequelize is essentially extending from classes with some modification to work with Sequelize#Model type.

Installation

npm i @automapper/sequelize

or with yarn:

yarn add @automapper/sequelize

peerDependencies

@automapper/sequelize depends on sequelize, @automapper/classes, and all of @automapper/classes peerDependencies

npm i sequelize @automapper/{core,classes} reflect-metadata
npm i --save-dev @types/sequelize @automapper/types

or with yarn:

yarn add sequelize @automapper/{core,classes} reflect-metadata
yarn add --dev @types/sequelize @automapper/types

Usage

• @automapper/sequelize provides sequelize as a (options: SequelizeInitializerOptions) => MapPluginInitializer. Pass sequelize() to createMapper to create a Mapper that uses sequelize plugin.

export interface SequelizeInitializerOptions {
  valueGetter?: <
    TGetterResult extends Record<string, unknown> = any,
    TModel extends Model<TGetterResult> = Model<TGetterResult>
  >(
    model: TModel
  ) => TGetterResult;
  init?: <
    TDestination extends Dictionary<TDestination> = any,
    TModel extends Model<TDestination> = Model<TDestination>
  >(
    destination: TModel,
    destinationObj: TDestination
  ) => TDestination;
}

• valueGetter is an optional getter that, if passed in, will be used to extract the value of the model after instantiation. By default, it will use sequelize#Model.get() if it's available.
• init is an optional init function that, if passed in, will be used to instantiate a Sequelize#Model after map. By default, it will use new Model(mapResult)

import { sequelize } from '@automapper/sequelize';
import { Model } from 'sequelize-typescript';

const mapper = createMapper({
  ...,
  pluginInitializer: sequelize()
  /**
   * or
   * sequelize({
   *   valueGetter: model => model.get(getterOptions),
   *   init: (model, mapResult) => model.init(mapResult, initOptions)
   * })
   */
})

class User extends Model {}

mapper.createMap(UserVm, User);
mapper.map(userVm, User, UserVm);
