JavaScript Extraction CLI & Package
This is a powerful tool for extracting JavaScript sources from URLs and web pages / HTTP responses. It offers a command-line interface (CLI) for straightforward URL processing and a package interface for custom integrations, making it ideal for pentesters, bug bounty hunters, and developers needing to extract JS sources efficiently.

## Installation
To install `getJS`, use the following command:
`go install github.com/003random/getJS/v2@latest`
## CLI Usage
### Options
`getJS` provides several command-line options to customize its behavior:
- `-url string`: The URL from which JavaScript sources should be extracted.
- `-input string`: Optional URLs input files. Each URL should be on a new line in plain text format. Can be used multiple times.
- `-output string`: Optional output file where results are written to. Can be used multiple times.
- `-complete`: Complete/Autofill relative URLs by adding the current origin.
- `-resolve`: Resolve the JavaScript files. Can only be used in combination with `--complete`.
- `-threads int`: The number of processing threads to spawn (default: 2).
- `-verbose`: Print verbose runtime information and errors.
- `-method string`: The request method used to fetch remote contents (default: "GET").
- `-header string`: Optional request headers to add to the requests. Can be used multiple times.
- `-timeout duration`: The request timeout while fetching remote contents (default: 5s).
### Examples
#### Extracting JavaScript from a Single URL
`getJS -url https://destroy.ai`
or
`curl https://destroy.ai | getJS`
#### Using Custom Request Options
`getJS -url "http://example.com" -header "User-Agent: foo bar" -method POST --timeout=15s`
#### Processing Multiple URLs from a File
`getJS -input foo.txt -input bar.txt`
#### Saving Results to an Output File
`getJS -url "http://example.com" -output results.txt`
## Package Usage
### Importing the Extractor
To use `getJS` as a package, you need to import the `extractor` package and utilize its functions directly.
### Example
```Go
package main
import (
"fmt"
"log"
"net/http"
"net/url"
"github.com/003random/getJS/extractor"
)
func main() {
baseURL, err := url.Parse("https://google.com")
if (err != nil) {
log.Fatalf("Error parsing base URL: %v", err)
}
resp, err := extractor.FetchResponse(baseURL.String(), "GET", http.Header{})
if (err != nil) {
log.Fatalf("Error fetching response: %v", err)
}
defer resp.Body.Close()
// Custom extraction points (optional).
extractionPoints := map[string][]string{
"script": {"src", "data-src"},
"a": {"href"},
}
sources, err := extractor.ExtractSources(resp.Body, extractionPoints)
if (err != nil) {
log.Fatalf("Error extracting sources: %v", err)
}
// Filtering and extending extracted sources.
filtered, err := extractor.Filter(sources, extractor.WithComplete(baseURL), extractor.WithResolve())
if (err != nil) {
log.Fatalf("Error filtering sources: %v", err)
}
for source := range filtered {
fmt.Println(source.String())
}
}
```
