Code Style

Types

• Use Flow for static typing with strict mode enabled
• Always include // @flow annotation at the top of JS files
• Export types with explicit naming: export type MyType = {...}

Formatting

• Prettier with 80-char line limit
• Single quotes, trailing commas
• Arrow function parentheses avoided when possible
• React component files named *.react.js

Naming

• kebab-case for filenames (enforced by unicorn/filename-case)
• Descriptive variable names

Imports

• Group imports with newlines between builtin/external and internal
• Alphabetize imports within groups
• No relative imports between workspaces - use workspace references

React

• Use functional components with hooks
• Follow exhaustive deps rule for useEffect/useCallback
• Component props should use explicit Flow types

Error Handling

• Use consistent returns in functions
• Handle all promise rejections
