Inspiration
The idea for API-GO was inspired by the need for a robust and scalable backend solution that can power modern e-commerce applications. We wanted to build an API that could handle various aspects of an online store, such as product management, user authentication, and order processing, all while being cloud-deployable and easily manageable through containerization.
What it does
API-GO is a backend service designed for e-commerce platforms. It provides endpoints for managing products, users, and orders. The API is built with Go for high performance and scalability, and it includes features like JWT-based authentication, role-based access control, and integration with a PostgreSQL database. The service is containerized using Docker and can be deployed on Google Cloud, making it easy to scale and manage in production environments.
How we built it
Backend: We used Go to build the API due to its performance advantages and strong support for concurrency. The application is organized into different modules, such as product, user, and order management, with each module responsible for its own set of functionalities.
- Database: PostgreSQL was chosen for its reliability and advanced features. We integrated the database with the Go backend using SQL and implemented data storage, retrieval, and manipulation functionalities.
- Containerization: The entire application is containerized using Docker, allowing for easy deployment and scalability. Docker Compose is used to manage multi-container setups, including the API and the PostgreSQL database.
- Cloud Deployment: The application is deployed on Google Cloud using Google Kubernetes Engine (GKE), which allows us to scale the application based on demand. We used Google Container Registry (GCR) to store our Docker images.
Challenges we ran into
Cloud Quota Issues: While deploying the application on Google Cloud, we encountered quota limitations, which required us to optimize our resource usage and request additional quota.
Containerization: Ensuring that the Docker images were built correctly and efficiently took some time, especially when dealing with multi-stage builds in the Dockerfile.
Database Integration: Managing migrations and ensuring that the PostgreSQL database was correctly integrated with the Go application was a challenging aspect of the project.
Accomplishments that we're proud of
- Successfully deploying a fully functional e-commerce backend to Google Cloud. Achieving a seamless integration between the Go API and the PostgreSQL database, with all essential CRUD operations functioning as intended.
- Implementing JWT-based authentication and role-based access control to secure the application.
What we learned
Cloud Deployment: We gained hands-on experience with deploying applications on Google Cloud, including managing resources and dealing with quotas.
Containerization: We deepened our understanding of Docker and Docker Compose, especially in the context of multi-container applications.
Go Language: We enhanced our skills in Go, particularly in building scalable and efficient APIs.
What's next for API-GO
Feature Expansion: We plan to add more features, such as payment processing and inventory management, to make the API more comprehensive.
Improved Documentation: We aim to provide detailed documentation to make it easier for developers to integrate API-GO into their projects.
Enhanced Security: We plan to implement additional security measures, such as OAuth2, to further protect user data and API access.
Scaling: We will focus on improving the scalability of the API, ensuring that it can handle increased traffic as usage grows.
