GetJS

getJS is a tool to extract all the javascript files from a set of given urls.

The urls can also be piped to getJS, or you can specify a singel url with the -url argument. getJS offers a range of options,

varying from completing the urls, to resolving the files.

Prerequisites

Make sure you have GO installed on your system.

Installing

getJS is written in GO. You can install it with go get:

go get github.com/003random/getJS

Usage

Note: When you supply urls from different sources, e.g. with stdin and an input file, it will add all the urls together :)
Example: echo "https://github.com" | getJS --url https://example.com --input domains.txt

To get all options, do:

getJS -h

Flag	Description	Example
--url	The url to get the javascript sources from	getJS --url https://poc-server.com
--method	The request method. e.g. POST or GET. Default: "GET"	getJS --url https://poc-server.com --method POST
--timeout	The request timeout. Default: 10 (secs)	getJS --url https://poc-server.com --timeout 15
--insecure	Skip SSL certificate verification. Use when the cert is expired or invalid	getJS --url https://poc-server.com --insecure
--header	Custom request header(s)	getJS --url https://poc-server.com --header "Authorization: Bearer token"
--input	Input file with urls	getJS --input domains.txt
--output	The file where to save the output to	getJS --output output.txt
--verbose	Display info of what is going on	getJS --verbose
--complete	Complete the urls. e.g. /js/index.js -> https://example.com/js/index.js	getJS --complete
--resolve	Resolve the output and filter out the non existing files (Can only be used in combination with --complete)	getJS --complete --resolve
--nocolors	Don't color the output	getJS --nocolors

Examples

getJS supports stdin data. To pipe urls to getJS, use the following:

$ cat domains.txt | getJS

To save the js files, you can use:

$ getJS --complete --url https://poc-server.com | xargs wget

If you would like the output to be in JSON format, you can combine it with @Tomnomnom's toJSON:

$ getJS --url https://poc-server.com | tojson

To feed urls from a file use:

$ getJS --input domains.txt

To save the results to a file, and don't display anything, use:

$ getJS --url https://poc-server.com --output results.txt

If you want to have a list of full urls as output use:

$ getJS --url domains.txt -complete

If you want to only show the existing js files, use:

$ getJS --url domains.txt --complete --resolve

This is my first tool written in GO. I created it to learn the language more. (useful feeback is always welcome!)
