Server Installation

Standard

Since we don't provide prebuild binaries, you have to build it yourself. For that you need Golang and Git installed on your system.

git clone https://github.com/maxibanki/golang-url-shortener # Clone repository
cd golang-url-shortener                                     # Go into it
go get -v ./...                                             # Fetch dependencies
go build                                                    # Build executable
./golang-url-shortener                                      # Run it

Docker Compose

Only execute the docker-compose.yml and adjust the environment variables to your needs.

Environment Variables:

Environment Variable	Description	Default Value
SHORTENER_DB_PATH	Relative or absolute path to the bolt DB	main.db
SHORTENER_LISTEN_ADDR	Address to which the http server should listen to	:8080
SHORTENER_ID_LENGTH	Length of the random short URL id	4

ShareX Configuration

This URL Shortener has fully support with ShareX. To use it, just import the configuration to your ShareX. For that you need to open the Destination settings => Other / Custom uploaders => Import => From Clipboard menu.

After you've done this, you need to set it as your standard URL Shortener. For that go back into your main menu => Destinations => URL Shortener => Custom URL Shortener.

HTTP Endpoints:

/api/v1/create POST

Create is the handler for creating entries, you need to provide only an URL. The response will always be JSON encoded and contain an URL with the short link.

There is a mechanism integrated, that you can call this endpoint with the following techniques:

• application/json
• application/x-www-form-urlencoded
• multipart/form-data

In all cases only add the long URL as a field with the key URL and you will get the response with the short URL.

/api/v1/info POST

This handler returns the information about an entry. This includes:

• Created At
• Last Visit
• Visitor counter

To use this, POST a JSON with the field id to the endpoint. It will return a JSON with the data.
