Strategies

A given Mapper is accompanied by a Strategy by providing strategyInitializer when using createMapper().

A Strategy will be responsible for:

- Discover metadata (eg: classes uses @AutoMap() decorator to discover the metadata of the properties on the Classes)
- Retrieve metadata: how the metadata should be retrieved from the discovery phase (eg: classes discovers and stores the metadata to Reflect, retrieve metadata simply gets them from Reflect)
- Apply metadata: how the metadata is applied to the Model

@automapper provides the following official strategies:

- automapper-classes: Work with TS/ES6 classes.
- automapper-pojos: Work with Interfaces/Types along with POJOs. In projects that do not make use of Class, pojos
can be used instead.
- automapper-mikro: Work together with TS/ES6 classes along with MikroORM
- automapper-sequelize`: Work together with TS/ES6 classes along with Sequelize
