This is the first time i've seen a tutorial when the instructor start first by writing a story and acceptance criteria on trello. That's really professional and close to real world. Thank you a ton, i 've learned so much!

🙏🙏🙏 what a professional teaching #Thomas. I haven't seen such kind of tutorial anywhere till date. If any beginner is taught coding this way he would emerge as a best developer within no time. My sincere thanks to you. Help us learn from you.

Excellent video! One thing to add here, all controller endpoints dealing with body data like create and update should use a DTO instead of an interface.

This allows you to configure Nest to use class-validator and class-transformer directly on the incoming data.

Looks like this:
class UserDTO implements User {
readonly id?: number;
readonly ....
...
}
user: User becomes user: UserDTO

Thomas quak would be in this case the advantages of using Observable instead of promises. I still don't really understand the difference and what I can gain from this use. And congratulations for the content is top.

If you experience this error in the UserService file, in the findOne(id: number) method"Argument of type '{ id: number; }' is not assignable to parameter of type 'FindOneOptions<UserEntity>'.
Object literal may only specify known properties, and 'id' does not exist in type 'FindOneOptions (etc)", instead of passing only "{ id }" use the typorm's "where" keyword like this: findOne(userId: number): Observable<User> { return { where: {id: userId} } )); } . I have changed the argument's name in the method just to avoid future confusion when going back to that function.

[DodaGarcia]

Jesus why are you hurting your Enter key like that

[johndash]

Hi, how can I make multiple save on repository ? I'd like to be able to send an array from object from the frontend, this array arrives on the nest typeorm backends and then each object of the array is saved on the repo with a loop ... any idea ?

[AnhTuanNguyen-vcqf]

What's different between user create(user: User): Observable<User> { return };
and create(user: User): Promise<User> {
return
}

Why you use 'rxjs Observable' in this code?

[milojianjunlu]

Could you explain the result is from?
return
map((user: User) => {
const {password, ...result} = user;
return result;
}),
catchError(err => throwError(err))
)
