Imports

The library is split into three entry points. Import only what you need:

import { Option, Result, Task } from "@nlozgachev/pipekit/Core";
import { pipe, flow }           from "@nlozgachev/pipekit/Composition";
import { Brand }                from "@nlozgachev/pipekit/Types";

Entry point	Contains
@nlozgachev/pipekit/Core	Option, Result, Validation, Task, TaskResult, TaskOption, TaskValidation, These, RemoteData, Arr, Rec
@nlozgachev/pipekit/Composition	pipe, flow, compose, curry, tap, memoize, and other function utilities
@nlozgachev/pipekit/Types	Brand, NonEmptyList

Requirements

• Node.js 22 or later (for npm/pnpm/yarn/bun installs)
• Deno 2 or later
• TypeScript 5.4 or later with strict mode enabled

Strict mode is required for the type-level guarantees — particularly exhaustiveness checking in match branches and narrowing in type guards — to work correctly.
