Installation & Usage

The main library requires you at least have Node.js installed.

A simple install and setup:

cd my_project/
npm i vile
npx vile init
npx vile analyze

Please see for more detailed info.


The core vile package comes with a general set of plugins that support basic multi-language analysis.

To analyze your code further, such as tracking outdated RubyGems, plugging in your favourite linter, tracking code complexity, or checking for vulnerabilities, you need to install extra plugins first.

Common Use Cases

  • Run vile a locally to analyze your code and print any issues or data
  • Run vile a -u on every build server commit to continuously analyze your code
  • Run vile a -d -p lint-plugin my/file.ext to run a plugin on a specific file
  • Run vile a -d -e -p lint-plugin,security-plugin to run certain lint checks during a build
