MERN URL Shortener

Motivation

In order to learn about the MERN Stack and Back-End development I decided to build a URL Shortener Server.

Getting Started

Development

1. Run just dev to start Docker Services
2. Run the HTTP Server using just server
3. Run the Front-End using just client in a separate terminal

Spec

The following section describes the server solution architecture and available endpoints.

REST API

The server solution serves a HTTP Server using the REST Spec. The available endpoints are listed below.

The column "🔐" determines wether the user should provide a token to perform the operation.

Public API
