What problem does it solve?
This Skill provides safe handling of nullable values and errors in TypeScript by leveraging fp-ts Option and Either, reducing runtime issues and improving type safety.
Core Features & Use Cases
- Option-based handling for nullable values, reducing undefined checks.
- Either-based error propagation with typed failures, enabling robust validation flows.
- Seamless composition with pipe and functional utilities to build readable pipelines.
- Use case: convert a nullable user id to an Option and then validate it with typed errors.
Quick Start
Install fp-ts and import the modules. Convert a nullable value to an Option using fromNullable and extract with getOrElse. Create and transform Either values with right/left and map/chain as needed.
