This is a Go service built using goswagger.io for handling file uploads. The service allows files to be uploaded through secured provider routes and provides a public route for retrieving files. The service uploads files to the uploads directory and stores file metadata in a PostgreSQL database.

Provider Routes

The service provides the following secured provider routes:

GET /files: Retrieves a list of files. POST /files: Uploads a new file. PUT /files/{id}: Updates an existing file.

Public Route

The service includes a public route for retrieving and resizing files. The URL format for the public route is:

GET /files/{size}:{hash}.{extension}
{size}: The desired dimensions for resizing the image in the format widthxheight (e.g., 400x400).
{hash}: The hashed name of the file.
{extension}: The file extension (e.g., jpg, png).

When a request is made to the public route with the specified size, hash, and extension, the service will return the resized image.

The files table stores the following information for each file:
