# v0.5.x to v0.6.x

### `@InjectTypeOrmQueryService`[​](#injecttypeormqueryservice "Direct link to injecttypeormqueryservice")

In the `v0.6.x` an new decorator was added `@InjectTypeOrmQueryService` to auto-create a TypeOrm query service.

This means you no longer need to manually create a service in order to expose your CRUD endpoints.

To enable decorator import the `NestjsQueryTypeOrmModule` to your module definition

```ts theme={null}
import { NestjsQueryTypeOrmModule } from '@ptc-org/nestjs-query-typeorm'
import { Module } from '@nestjs/common'
import { TodoItemEntity } from './todo-item.entity'
import { TodoItemResolver } from './todo-item.resolver'

@Module({
  providers: [TodoItemResolver],
  imports: [NestjsQueryTypeOrmModule.forFeature([TodoItemEntity])]
})
export class TodoItemModule {}
```

One you have imported the module you can inject a `TypeOrmQueryService`.

```ts theme={null}
import { QueryService } from '@ptc-org/nestjs-query-core'
import { CRUDResolver } from '@ptc-org/nestjs-query-graphql'
import { Resolver } from '@nestjs/graphql'
import { InjectTypeOrmQueryService } from '@ptc-org/nestjs-query-typeorm'
import { TodoItemDTO } from './dto/todo-item.dto'
import { TodoItemEntity } from './todo-item.entity'

@Resolver(() => TodoItemDTO)
export class TodoItemResolver extends CRUDResolver(TodoItemDTO) {

  constructor(@InjectTypeOrmQueryService(TodoItemEntity) readonly service: QueryService<TodoItemEntity>) {
    super(service)
  }
}
```

## `TypeOrmQueryService`[​](#typeormqueryservice "Direct link to typeormqueryservice")

In the previous version of `@nestjs-query` the `TypeOrmQueryService` translated between the DTO and Entity. For a more in-depth description see [#41](https://github.com/tripss/nestjs-query/issues/41)

In the latest version the `TypeOrmQueryService` only operates on entities.

`v0.5.x`

```ts theme={null}
import { QueryService } from '@ptc-org/nestjs-query-core'
import { TypeOrmQueryService } from '@ptc-org/nestjs-query-typeorm'
import { InjectRepository } from '@nestjs/typeorm'
import { Repository } from 'typeorm'
import { TodoItemDTO } from './todo-item.dto'
import { TodoItemEntity } from './todo-item.entity'

@QueryService(TodoItemDTO)
export class TodoItemService extends TypeOrmQueryService<TodoItemDTO, TodoItemEntity> {

  constructor(@InjectRepository(TodoItemEntity) readonly repo: Repository<TodoItemEntity>) {
    super(repo)
  }
}
```

`v0.6.x`

```ts theme={null}
import { QueryService } from '@ptc-org/nestjs-query-core'
import { TypeOrmQueryService } from '@ptc-org/nestjs-query-typeorm'
import { InjectRepository } from '@nestjs/typeorm'
import { Repository } from 'typeorm'
import { TodoItemEntity } from './todo-item.entity'

@QueryService(TodoItemEntity)
export class TodoItemService extends TypeOrmQueryService<TodoItemEntity> {

  constructor(@InjectRepository(TodoItemEntity) readonly repo: Repository<TodoItemEntity>) {
    super(repo)
  }
}
```

## `AssemblerQueryService`[​](#assemblerqueryservice "Direct link to assemblerqueryservice")

In previous versions of `nestjs-query` the `QueryService` would automatically translate betwen your DTO and database type. This created a soft-dependecy between the persistence service and the view layer. In `v0.6.0` `AssemblerQueryService` was introduced to handle translating between your DTO and persistence type.

```ts theme={null}
import { AssemblerQueryService, QueryService } from '@ptc-org/nestjs-query-core'
import { InjectTypeOrmQueryService } from '@ptc-org/nestjs-query-typeorm'
import { TodoItemDTO } from './todo-item.dto'
import { TodoItemAssembler } from './todo-item.assembler'
import { TodoItemEntity } from './todo-item.entity'

@QueryService(TodoItemDTO)
export class TodoItemService extends AssemblerQueryService<TodoItemDTO, TodoItemEntity> {

  constructor(
    assembler: TodoItemAssembler,

    @InjectTypeOrmQueryService(TodoItemEntity) queryService: QueryService<TodoItemEntity>
  ) {
    super(assembler, queryService)
  }
}
```
