This is a simple web application written in Go that provides a service to watermark documents. The application is designed for a global publishing company that publishes books and journals. It allows specific users to watermark documents, which have a title, author, and a watermark property that can be in one of three states: Started, InProgress, and Finished.
The publishing company needs a reliable way to protect their intellectual property by adding a watermark to their documents. The watermarking process should be performed by authorized users, and once a document is watermarked, it can never be re-marked.
Here is an example of a document object:
{
"content": "book",
"title": "The Dark Code",
"author": "Bruce Wayne",
"topic": "Science"
}The Document Watermarking Service provides the following functionality:
- Allow specific set of users to watermark documents.
- Marking the document in one of three states: Started, InProgress, and Finished.
- Preventing re-marking of a document after it has been watermarked.
In this project, we will have 3 microservices: Authentication Service, Database Service and the Watermark Service. We have a PostgreSQL database server and an API-Gateway.
This application is built using the following technologies:
- Go
- Gin Web Framework
- MongoDB
To use this application, you need to have Go and MongoDB installed on your machine. Follow these steps to get started:
- Clone the repository to your local machine.
- Navigate to the project directory and run
go mod downloadto download the required packages. - Start the server by running
go run main.go. - Open your web browser and go to
http://localhost:8080to access the application.
The Document Watermarking Service is a simple but effective solution for protecting the publishing company's intellectual property. It allows authorized users to watermark documents and ensures that once a document is watermarked, it can never be re-marked.
