Features

TypeScript Strict Mode

Based on tseslint.configs.strictTypeChecked:

• strict-boolean-expressions - No implicit boolean coercion
• no-floating-promises - All promises must be handled
• no-explicit-any - Forbids any type
• consistent-type-imports - Forces import type syntax
• switch-exhaustiveness-check - All cases must be covered

Functional Programming

Based on eslint-plugin-functional:

• no-expression-statements - No side effects without return
• no-conditional-statements - Forces ternaries/pattern matching
• no-throw-statements - Use Effect instead of throw
• no-try-statements - Use Effect instead of try/catch
• immutable-data - No object/array mutation

Security

Based on eslint-plugin-security:

• detect-unsafe-regex - Detects ReDoS-vulnerable regex
• detect-eval-with-expression - Forbids eval with expressions
• detect-object-injection - Warns on dynamic property access

Code Quality

| Rule | Value | Description | | ------------------------ | ----- | ---------------------------------------- | | max-depth | 4 | Maximum nesting depth | | max-lines-per-function | 60 | Maximum lines per function | | complexity | 15 | Maximum cyclomatic complexity | | no-console | error | Forbids console.log (allows warn, error) |

Effect.js Patterns

The following patterns are automatically allowed:

Effect.runPromise(...)
pipe(value, Effect.map(...))
Layer.succeed(...)
app.get('/path', handler)

Test Files

Strict rules are disabled for *.test.ts and *.spec.ts files.
