This is my model. There's a many-to-many relationship between user and post.

My current querybuilder:

getRepository(Post)
    .createQueryBuilder("post")
    .innerJoinAndSelect("post.creator", "user")
    .select(["post.id", "post.content", "post.createdAt", "user.id", "user.username", "user.avatar"])
    .orderBy("post.createdAt", "DESC")

Results:

[{
    id: 18,
    content: "I'm Ana.",
    createdAt: "2021-11-09T04:06:48.931Z",
    creator: {
        id: 31,
        username: "ana",
        avatar: "https://avatars.dicebear.com/api/female/ana.svg"
    }
}]

I want to add another field "liked", a boolean value telling me if the logged-in user has liked the post. I could use getRawMany, but the json would be completely flat, and I don't want to destroy the current API format. Is there a way I can get the best of both worlds?
