如何在Loopback 4存储库中调用MongoDB的“ $ inc”？

Question

我正在尝试对Typescript和loopback-connector-mongodb库执行以下操作，但收到错误Object literal may only specify known properties。

interface Foo {
  likes: number;
}

// increase likes with MongoDB's '$inc'
async increaseLikes(id: string): Promise<void> {
  await this.fooRepository.updateById(id, {"$inc": {likes: 1}})
}

MongoDB docs

即使代码有效，[，这也是Typescript编译错误。

可以用// @ts-ignore抑制该错误

Docs

interface Foo {
  likes: number;
}

// increase likes with MongoDB's '$inc'
async increaseLikes(id: string): Promise<void> {
  // error suppressed to allow use of MongoDB's extended operators
  // @ts-ignore
  await this.fooRepository.updateById(id, {"$inc": {likes: 1}})
}
