This guide provides a quick reference for 'pipe' and 'flow' utilities in fp-ts. The `pipe` function is used to chain multiple operations to transform a specific value, while `flow` allows you to create reusable, composed functions (pipelines). It is essential for implementing clean, declarative data manipulation and functional composition in TypeScript.

This guide offers a jargon-free, practical approach to functional programming using fp-ts in TypeScript. It focuses on the 80/20 principles, teaching core patterns like Pipe, Option, and Either. Learn how to handle missing values safely, manage errors explicitly, and chain operations cleanly, improving code readability without over-engineering.

Master robust and type-safe patterns for React development using fp-ts. This guide covers managing state with Option, sophisticated form validation using Either (collecting all errors), and handling asynchronous data fetching with TaskEither. It promotes a highly functional, predictable coding style for React 18/19 and Next.js.

This comprehensive guide provides patterns and strategies for migrating existing imperative TypeScript code to functional programming patterns using fp-ts. Learn how to replace traditional structures like try/catch blocks, null checks, and callbacks with robust, type-safe functional equivalents (e.g., Either, Option, Task). It is essential for developers aiming to increase code reliability and maintainability in large TypeScript codebases.

TaskEither is a functional programming utility from fp-ts designed for handling asynchronous operations that might fail. It provides a robust, type-safe mechanism for managing complex async workflows, such as chained API calls or promise wrappers. Instead of relying on traditional try/catch blocks where errors can be lost, TaskEither forces the developer to explicitly handle both success and failure paths, making error management predictable and composable.

A comprehensive quick reference guide for functional programming types in TypeScript using the fp-ts library. It helps users decide which type (`Option`, `Either`, `Task`, etc.) to use based on whether operations are synchronous, asynchronous, and if they involve errors or missing values. It provides decision trees, common import patterns, and utility function patterns for robust TypeScript development.

Guides growth engineers through evaluating, designing, and launching free marketing tools that drive traffic, leads, and backlinks without paid ads, covering idea scoring, UX, lead capture, and launch tactics.

Automates the generation of production-ready Playwright end-to-end (E2E) tests. By accepting high-level inputs such as user stories, feature descriptions, or component names, this tool analyzes the codebase, selects appropriate testing templates (e.g., CRUD, login, checkout), and generates structured, best-practice test files. It ensures adherence to modern web testing standards, including proper locator strategies (getByRole), assertion techniques, and project conventions (fixtures, page objects).

This skill fetches unread GitHub Pull Requests (PRs) that require review from a specified team or were opened by a team member. It is ideal for users who need to check their team's review queue, find PRs needing attention, or automate the process of reviewing open code submissions without manually browsing GitHub notifications. Requires GitHub CLI authentication.

A rigorous framework designed to audit GitHub Actions workflows for exploitable security vulnerabilities. This skill focuses strictly on real-world attack patterns, requiring every identified finding to include a concrete exploitation scenario (Entry Point, Payload, Impact). Ideal for securing CI/CD pipelines against external attackers.

This comprehensive tool helps users set, track, and optimize personal health goals using deep data analysis. It validates goals against the SMART criteria (Specific, Measurable, Achievable, Relevant, Time-bound) and tracks progress by correlating diverse health data, including nutrition, exercise, and sleep patterns. Key features include habit formation analysis, motivation assessment, identifying roadblocks, and generating interactive reports with ECharts visualizations, providing a holistic view of wellness journeys.

Scans Go codebases for security vulnerabilities, highlighting risky patterns, insecure dependencies, and misconfigurations so auditors can catch issues before deployment.
