A high-performance backend for the Wizzl app, built using Go and Fiber. Wizzl is a simple messaging platform available as both a website and app.
The core logic of the app resides in the app folder. This includes HTTP handlers, request validation structs, services, and WebSocket event handlers. You'll find utility functions and globally accessible structs in the pkg folder. The application's routes are organized under the routes folder. Additionally, we store email templates in the templates folder.
We also provide a Makefile that simplifies handler creation. Using the command make handler name=custom_handler, you can generate a new handler file under app/handlers with a pre-defined struct and method.
Wizzl is live at wizzl.app, and anyone can use it. If you'd like to run your own instance of Wizzl, follow these steps:
Ensure you have docker and docker-compose installed. Then, simply run:
docker compose upThis will start the backend service. By default, Wizzl runs on 127.0.0.1:3000, but you can modify the docker-compose.yml file to change the port.
We use a MySQL MariaDB database alongside GORM as our ORM, which is a perfect fit for the app. Redis is also integrated to improve performance, cache chat data, and group users, enabling real-time permission-based message delivery.
All database models are located in the database/models folder. To add new models, define them in this folder, and manage relationships in the relations.go file for easier maintenance.
Our backend employs bcrypt for password encryption and AES for message encryption, ensuring user privacy. The encryption keys are securely stored.
We truly appreciate any support, whether it’s through contributions, feedback, or spreading the word about Wizzl. Every bit helps us improve the platform and continue developing new features.
