goDom is a simple tool that extracts fully-qualified domain names from the HTTP response body of a given URL. It uses regular expressions to match URLs that start with http:// or https://, and extracts the domain names from them.

Useful to extract subdomains from JavaScript files.

To use goDom, simply pipe a URL to the tool, for example:

echo https://example.com/main.js | goDom

or pipe a list of urls:

cat urls.txt | goDom

This will extract all the fully-qualified domain names it finds in the HTTP response body of the given URL and print them to the console.

To install goDom, simply clone this repository and build the tool using the go build command:

git clone https://github.com/ninposec/goDom.git
cd goDom
go build

This will create an executable file called goDom in the current directory. You can then move this file to a directory in your system's $PATH environment variable to use it globally.

Alternatively, you can install the tool using the go get command:

go install github.com/ninposec/goDom@latest

This will download and install the tool in your system's $GOPATH/bin directory.
