Say Goodbye to Redundant CLI Validation: Introducing Optique
2025-09-07
Tired of writing repetitive command-line argument validation code? The author shares their experience building the Optique library. Optique leverages parser combinators to directly parse command-line arguments into the expected type, eliminating the need for subsequent validation and avoiding issues like validation logic getting out of sync with options. TypeScript's type inference catches errors at compile time, significantly improving development efficiency and code reliability. While not a silver bullet, Optique dramatically reduces code and improves maintainability for complex CLI tools.
