## Code Style Rules
 
### General Principles
 
-**TypeScript**: All code must be strictly typed, leverage TypeScript's type safety features
 
### Code style rules
 
-Interfaces over types - use interfaces for object types
-Use enum for constant values, prefer them over string literals
-Export all types by default
-Use type guards instead of type assertions
 
### Best Practices
 
#### Library-First Approach
 
-Common areas where libraries should be preferred:
  -Date/time manipulation → date-fns, dayjs
  -Form validation → joi, yup, zod
  -HTTP requests → axios, got
  -State management → Redux, MobX, Zustand
  -Utility functions → lodash, ramda
 
#### Code Quality
 
-Use destructuring of objects where possible:
  -Instead of `const name = user.name` use `const { name } = user`
  -Instead of `const result = await getUser(userId)` use `const { data: user } = await getUser(userId)`
  -Instead of `const parseData = (data) => data.name` use `const parseData = ({ name }) => name`
-Use `ms` package for time related configuration and environment variables, instead of multiplying numbers by 1000
