Pragmatic Functional Programming

What problem does it solve?

Pragmatic Functional Programming eliminates the cognitive load of FP by presenting a practical, jargon-free approach to applying core patterns in real TypeScript projects.

Core Features & Use Cases

• Pipe: Build clear, linear data transformations using pipe from fp-ts/function.
• Option & Either: Handle missing values and errors in a typed, composable way.
• Core patterns in practice: Learn to compose readable pipelines for validation, parsing, and formatting in everyday code.
• Use Case: Implement a small data processor that parses input, validates it, and formats the result in a single, readable flow.

Quick Start

Try the Pragmatic FP guide by applying a simple 3-step pipeline (parse → validate → format) to a sample data object.
