About

This is a template repo, demonstrating GitHub's Code Scanning capability, using ESLint to generate a "code scanning alert" in GitHub's Security tab:

How it works

• The ESLint analysis workflow runs on a schedule, and on every push
• The ESLint output is formatted as SARIF, using the @microsoft/eslint-formatter-sarif package
• The SARIF report is submitted to GitHub via the github/codeql-action/upload-sarif action

Getting started

1. Register for the code scanning beta here
2. Generate a copy of this repo
3. Push a commit -- it can even be an empty commit (git commit --allow-empty)
4. Observe as a new security alert is generated
