fp-ts-pragmatic
A practical, jargon-free guide to fp-ts functional programming - the 80/20 approach that gets results without the academic overhead. Use when writing TypeScript with fp-ts library.
npx skills add sickn33/agentic-awesome-skills --skill fp-ts-pragmatic --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Pragmatic Functional Programming **Read this first.** This guide cuts through the academic jargon and shows you what actually matters. No category theory. No abstract nonsense. Just patterns that make your code better. ## When to Use This Skill - When starting with fp-ts and need practical guidance - When writing TypeScript code that handles nullable values, errors, or async operations - When you want cleaner, more maintainable functional code without the academic overhead - When refactoring imperative code to functional style ## The Golden Rule > **If functional programming makes your code harder to read, don't use it.** FP is a tool, not a religion. Use it when it helps. Skip it when it doesn't. --- ## The 80/20 of FP These five patterns give you most of the benefits. Master these before exploring anything else. ### 1. Pipe: Chain Operations Clearly Instead of nesting function calls or creating intermediate variables, chain operations in reading order. ```typescript import { pipe } from 'fp-ts/function' // Before: Hard to read (inside-out) const result = format(validate(parse(input))) // Before: Too many variables const parsed = parse(input) const validated = validate(parsed) c

What does the fp-ts-pragmatic skill do?
A practical, jargon-free guide to fp-ts functional programming - the 80/20 approach that gets results without the academic overhead. Use when writing TypeScript with fp-ts library.
How do I install it?
Run `npx skills add sickn33/agentic-awesome-skills --skill fp-ts-pragmatic --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From sickn33/agentic-awesome-skills, a repository with 44,414 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
