Eslint-plugin-security-rules NPM

ESLint security rules to help harden your project as early as possible.

NB: This project was written as an artefact for a master's thesis at the IT University of Copenhagen and it should still be considered a work in progress.

Installation

Requires Node.js >=14
Requires ESLint >=8

yarn add --dev eslint-plugin-security-rules

Usage

To include the recommended eslint-plugin-security-rules to your ruleset add the following to your .eslintrc configuration:

{
  "extends": [
    "plugin:security-rules/recommended"
  ],
  // Please include the environments that you use when using this plugin. Doing
  // so will enhance the tracing algorithm greatly.
  "env": { 
    "node": true,
    "browser": true,
    "es6": true
  },
  "overrides": [
    {
      "files": ["*.ts", "*.tsx"],
      "extends": ["plugin:@typescript-eslint/recommended"],
      // If you would like to improve the accuracy of the tracing algorithm
      // when using typescript, then please include the "project" configuration
      // for the @typescript-eslint/parser.
      // See more at 
      // https://github.com/typescript-eslint/typescript-eslint/tree/main/packages/parser#parseroptionsproject
      "parserOptions": {
        "project": ["./tsconfig.json"]
      }
    },
  ]
}
