API for blog build with TypeScript, Express, Node.js, PostgreSQL, JsonWebToken, and bcrypt. Deployed on AWS Elastic Beanstalk and using AWS S3 for image storage.

Blog backend with NodeJS & Express

This repo is the backend portion of a blogging app that allows users to write a blog post consisting of a photo, title, and content. All posts are public. Only signed up users can write or edit their posts.

The backend is hosted here: https://www.mjbblogbackend.com The app is here: https://next-js-tailwind-three.vercel.app/

Authentication overview.

Login is handled by JWT authentication. Once a user logs in, they receive an access token in the body of the response, and a refresh token as an HTTP Only cookie. A refresh timer is triggered on login and will silenty refresh the access token as long as a valid refresh token is present (in the form of the HTTP Only cookie) when making the refresh_token call. The access token provides access to api endpoints protected by an authentication middleware.
