Dozer Authorization Sample - Movie Ticket Booking App

This repository contains a sample application demonstrating the power of Dozer's data API authorization capabilities. Dozer simplifies the task of adding an authorization layer to your data APIs. One method it employs is the use of JSON Web Tokens (JWT), a widely accepted industry standard for secure claim representation between two parties.

In this sample, we are building a straightforward movie ticket booking app, which defines two roles: user (public) and admin. The user can book tickets and view their bookings, while the admin has complete access to all APIs.

Getting Started

  1. Clone the dozer-samples repository and change the directory to the project directory:
git clone [email protected]:getdozer/dozer-samples.git && cd dozer-samples/usecases/api-auth/
  1. Start the PostgreSQL database which contains the movie dataset. The Docker Compose file is under the database folder:
cd database
docker-compose up -d
cd ..
  1. Generate a master token for auth by running the command from the project root directory where dozer-config.yaml is located:
dozer security generate-token
  1. Copy the MASTER_TOKEN generated from the previous step and export the MASTER_TOKEN as an environment variable
export MASTER_TOKEN=your_token_here
  1. Start the Dozer app. Dozer will start running, handling the data operations and APIs authorization as defined in your configuration. To do this, simply run the command:
dozer run
  1. Open the new terminal and change the directory to the server folder and install required package dependencies:
cd server && yarn install
  1. Run the server app:
 node index.js

The server app takes care of the user login feature and passes the auto-generated auth token with the master token to subsequent requests to the client app while communicating

  1. In a new terminal, navigate to the client directory, install client dependencies and start the app: 
    cd ../client && yarn install && yarn start

Go to localhost:3000 to see the user side view of the app that lets you book the ticket. To see the admin dashboard go to localhost:3000/admin/dashboard. Enter username and password as "admin" to see the real-time updates on ticket sales.

Note: Always ensure that your MASTER_TOKEN is kept secure. Do not commit this information to your version control system.

About JWT

JWT is a compact, URL-safe means of representing claims to be transferred between two parties. You can find more about JWT here.
