Chalk comes with an easy to use composable API where you just chain and nest the styles you want.
This is free and open source software.
Key Features
- Fluent, auto-complete-friendly API for maximum coding efficiency.
- Ability to nest styles.
- Proper handling of styling edge cases (same test cases as Chalk).
- Auto-detection of terminal color capabilities.
- 256/Truecolor color support, with fallback to basic colors depending on capabilities.
- Same conventions as Chalk to manually control color modes via FORCE_COLOR.
- No dependencies.
- Fully typed (mypy strict), no stubs required.
