Overview

Use automated tools to analyze code without executing it, catching bugs, security issues, and style violations early.

When to Use

• Enforcing coding standards
• Security vulnerability detection
• Bug prevention
• Code review automation
• CI/CD pipelines
• Pre-commit hooks
• Refactoring assistance

Quick Start

Minimal working example:

// .eslintrc.js
module.exports = {
  extends: [
    "eslint:recommended",
    "plugin:@typescript-eslint/recommended",
    "plugin:security/recommended",
  ],
  plugins: ["@typescript-eslint", "security", "import"],
  rules: {
    "no-console": ["warn", { allow: ["error", "warn"] }],
    "no-unused-vars": "error",
    "prefer-const": "error",
    eqeqeq: ["error", "always"],
    "no-eval": "error",
    "security/detect-object-injection": "warn",
    "security/detect-non-literal-regexp": "warn",
    "@typescript-eslint/no-explicit-any": "warn",
    "@typescript-eslint/explicit-function-return-type": "error",
    "import/order": [
      "error",
      {
        groups: [
          "builtin",
          "external",
          "internal",
// ... (see reference guides for full implementation)

Best Practices

✅ DO

• Run linters in CI/CD
• Use pre-commit hooks
• Configure IDE integration
• Fix issues incrementally
• Document custom rules
• Share configuration across team
• Automate security scanning

❌ DON'T

• Ignore all warnings
• Skip linter setup
• Commit lint violations
• Use overly strict rules initially
• Skip security scans
• Disable rules without reason
