antithrow

Rust-style Result<T, E> types for type-safe error handling in TypeScript, without throwing exceptions.

Where to start

The documentation is organised into four sections, each with a different purpose.

• Tutorial — a single end-to-end lesson. Start here if you have never used antithrow before.
• How-to guides — short, goal-oriented recipes. Go here when you know what you want to achieve.
• Reference — the complete API surface for every package. Go here to look up a specific export.
• Explanation — the reasoning behind antithrow's design. Go here to understand why things are the way they are.

Packages

Package	Purpose
antithrow	The core Result, Ok, Err, Pending, and composition utilities.
@antithrow/std	Non-throwing wrappers around standard globals (fetch, JSON, base64, URI helpers).
@antithrow/node	Non-throwing wrappers around Node.js APIs (fs/promises, os).
@antithrow/standard-schema	Bridge Standard Schema validators (Zod, Valibot, ArkType) to antithrow results.
@antithrow/eslint-plugin	ESLint rules that enforce correct Result usage.
