tsentials

Railway-oriented error handling and functional utilities for TypeScript

Replaces try/catch exception handling with explicit Result, Maybe, and Union types in TypeScript projects. Eliminates hidden runtime crashes, null reference bugs, and scattered validation logic across services. Provides ready-made patterns for async pipelines, business rules, HTTP calls, JSON parsing, and domain entities so agents write correct code faster.

npx skills add senrecep/tsentials --all -g -y

Available:

Gives the agent exact import paths, API signatures, and critical naming rules for every tsentials module so it writes correct railway-oriented TypeScript code without guessing method names.

Frequently Asked Questions

FAQPage Schema

How to install tsentials?▼

Run `npx skills add senrecep/tsentials --all -g -y` in your terminal to install all skills in this suite globally.

What problem does tsentials solve?▼

It replaces exception-based error handling with explicit Result and Maybe types, so failures and missing values are visible in function signatures instead of crashing at runtime.

How do the tsentials skills help an AI coding agent?▼

Each skill documents exact method names, import paths, and common pitfalls, so the agent generates correct tsentials code on the first try without inventing nonexistent APIs.

Does tsentials work with Claude Code and other coding agents?▼

Yes. All skills follow the standard SKILL.md format and work in Claude Code, Cursor, Codex, and other compatible coding environments.

What TypeScript version does tsentials require?▼

It requires Node.js 18 or higher and TypeScript 5.0 or higher, and it is ESM-only with full tree-shaking support.
