### Description
I was developing jsleak during most of my free time for my own need.It is easy-to-use command-line tool designed to uncover secrets and links in JavaScript files or source code. The jsleak was inspired by [Linkfinder](https://github.com/GerbenJavado/LinkFinder) and regexes are collected from multiple sources.
### Features:
- Discover secrets in JS files such as API keys, tokens, and passwords.
- Identify links in the source code.
- Complete Url Function
- Concurrent processing for scanning of multiple Urls
- Check status code if the url is alive or not
### Latest Update
Jsleak now supports regex patterns from secrets-patterns-db [https://github.com/mazen160/secrets-patterns-db](https://github.com/mazen160/secrets-patterns-db).
If you want to use your own custom regex patterns, you can place them in a YAML file following the template below.
```
patterns:
- pattern:
name: Amazon MWS Auth Token
regex: "amzn\\.mws\\.[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}"
confidence: low
```
