NodeJsScan is a static security code scanner (SAST) for Node.js applications.

Configure & Run

Install Postgres and configure SQLALCHEMY_DATABASE_URI in core/settings.py

pip3 install -r requirements.txt
python3 migrate.py # Run once to create database entries required
python3 app.py # Testing Environment
gunicorn -b 0.0.0.0:9090 app:app --workers 3 --timeout 10000 # Production Environment

This will run it on http://0.0.0.0:9090

If you need to debug, set DEBUG = True in core/settings.py

NodeJsScan CLI

The command line interface (CLI) allows you to integrate it with DevSecOps CI/CD pipelines. The results are in JSON format. When you use CLI the results are never stored with it in the backend.

virtualenv venv -p python3
source venv/bin/activate
(venv)pip install nodejsscan
(venv)$ nodejsscan
usage: nodejsscan [-h] [-f FILE [FILE ...]] [-d DIRECTORY [DIRECTORY ...]]
                  [-o OUTPUT] [-v]

optional arguments:
  -h, --help            show this help message and exit
  -f FILE [FILE ...], --file FILE [FILE ...]
                        Node.js file(s) to scan
  -d DIRECTORY [DIRECTORY ...], --directory DIRECTORY [DIRECTORY ...]
                        Node.js source code directory/directories to scan
  -o OUTPUT, --output OUTPUT
                        Output file to save JSON report
  -v, --version         Show nodejsscan version
