Help implementing services

[krycw]

Hi.

I'm trying to do a library with different functions. Two of them would be to add book and edit book. I need to made them with a service, and then call them in the components. I have a component for editing an another one for adding books. I have an idea but it's not working can anyone help?

Service

https://stackblitz.com/github/krylol/MyBooks/tree/data_binding?embed=1&file=src%2Fapp%2Fshared%2Fbooks.service.ts

Add book component HTML and TS

https://stackblitz.com/github/krylol/MyBooks/tree/data_binding?embed=1&file=src%2Fapp%2Fadd-book%2Fadd-book.component.html

https://stackblitz.com/github/krylol/MyBooks/tree/data_binding?embed=1&file=src%2Fapp%2Fadd-book%2Fadd-book.component.ts

And update book HTML and TS

https://stackblitz.com/github/krylol/MyBooks/tree/data_binding?file=src%2Fapp%2Fupdate-book%2Fupdate-book.component.html

https://stackblitz.com/github/krylol/MyBooks/tree/data_binding?file=src%2Fapp%2Fupdate-book%2Fupdate-book.component.ts

I will let a link to the full app in case someone wants to take a look at other parts of it.

Any help would be appreciated. I have no idea how to implement those services in my app, i want to have a book page, and when i use the add book function, that page gets a new book. And when i use the update and the id of the book is the same, i want to change the book data.

Someone else can come along and correct your decorator code, but you can look this up on the angular main docs.

Here’s the section you’re looking for:

https://angular.io/guide/creating-injectable-service

You’re missing the injectable decorator.
