@trailhead/core

Foundation package providing unified Result types, enhanced error handling, and performance-optimized utilities

Foundation package for the Trailhead ecosystem providing unified Result types, enhanced error handling, and performance-optimized type guards.

Installation

npm install @trailhead/core

Quick Example

import { ok, err, type Result } from '@trailhead/core'

const divide = (a: number, b: number): Result<number, Error> => {
  if (b === 0) {
    return err(new Error('Division by zero'))
  }
  return ok(a / b)
}

const result = divide(10, 2)
if (result.isOk()) {
  console.log('Result:', result.value) // 5
} else {
  console.error('Error:', result.error.message)
}

Key Features

• Unified Result types - Single source of truth for Result operations across the ecosystem
• Enhanced error context - Rich debugging with operation context, timestamps, and severity
• Performance-optimized type guards - Zero-overhead validation for critical paths
• Functional utilities - Composition helpers and Result-based patterns

Documentation

• API Documentation - Complete API reference
• Result Types Pattern - Understanding Result types
• Functional Architecture - Functional programming patterns
