NestJS GraphQL Blog Back-End

Description

The back-end of my personal blog made with NestJS & GraphQL.

Architecture

This project is divided into three main entities/classes:

• Users: the users of the blog, which are divided into admins, publishers and normal users.
• Posts: the posts of the blog.
• Series: the series of a given group of blog posts.
• Comments: the comments, or user interaction with the blog posts.

The posts are related to the series by a many-to-many-to-many relationship, with tags as an intermediate table. It follows a team blog approach were there can be multiple publishers and admins, so it's perfect for a team as well as a single individual. In terms of table relationships apart from some exceptions they are loaded by dataloaders, even the paginated relationships.
