BLOG-API

A blogging-API built in the fulfilment of the Altschool of Engineering focused in Backend Engineering (NodeJS) Second Semester Requirement

Backend NodeJS Second Semester Examination Project

Requirements

Requirements for the examination project

• Users should have a first_name, last_name, email, password,

• A user should be able to sign up and sign in into the blog app

• Use JWT as authentication strategy and expire the token after 1 hour

• The owner of the blog should be able to delete the blog in draft or published state

• The owner of the blog should be able to get a list of their blogs.

• The endpoint should be paginated

• It should be filterable by state

• Blogs created should have title, description, tags, author, timestamp, state, read_count, reading_time and body.

• The list of blogs endpoint that can be accessed by both logged in and not logged in users should be paginated:

• default it to 20 blogs per page.

• It should also be searchable by author, title and tags.

• It should also be orderable by read_count, reading_time and timestamp

• When a single blog is requested, the api should return the user information (the author) with the blog. The read_count of the blog too should be updated by 1

• Come up with any algorithm for calculating the reading_time of the blog.

• Write tests for all endpoints
