v1.9.1

Full Changelog: v1.9.0...v1.9.1

v1.8.1

Naming conventions and linter fixes

v1.8.0

Type safety improvements for Effect templates

v1.7.1

Bug Fixes

• Fix catchTags type inference for Effect error channels

Problem

TypeScript was inferring never for catchTags handlers because errors weren't properly in the Effect error channel.

Solution

• Service template now adds existence checks before update/delete that explicitly throw NotFoundError
• Handlers template now catches DatabaseInternalError in addition to domain errors
• Removed unused error imports (catchTags uses string literals, not runtime types)
• Uses centralized env module instead of direct process.env access

Breaking Changes: None - this is a fix for generated code that was previously not type-safe.

v1.7.0

Features

• Comprehensive biome lint compliance for all generator templates
• Improved code formatting and linting across all generated libraries

v1.5.2 - Remove Type Coercions and Assertions

Patch Changes

Remove unnecessary type coercions and assertions

This patch demonstrates TypeScript's type inference capabilities by removing all unnecessary type coercions, assertions, and type narrowing from generated code templates.

Changes:

1. Repository Interface Template - Replaced test layer as any assertions with honest placeholder implementations using Effect.dieMessage. Test layers now guide developers to provide their own mocks.

2. Repository Template - Removed non-null assertions and type casts:

   • Replaced store.get(id)\! with Option.fromNullable(store.get(id))
   • Replaced Effect.fail(...) as Effect.Effect<T, never, never> with Effect.dieMessage(...)

3. Provider Service Interface Template - Replaced test layer type assertions with placeholder implementations. No more as Resource or as PaginatedResult assertions.

4. Provider Service Template - Improved config pattern:

   • Replaced || with ?? for default values (properly handles falsy values like 0)
   • Removed \! non-null assertions on retry config (nullish coalescing ensures values are never undefined)
   • Removed as const type narrowing on health check status

5. TypeScript Builder - Replaced targetMap.get(from)\! with proper undefined check that throws descriptive error.

Architecture Improvement:

Test layers now use honest placeholder implementations instead of creating mock entities with type assertions. This approach:

• Achieves zero type assertions without compromising branded type safety
• Guides developers to provide their own test implementations
• Demonstrates proper type-driven design where TypeScript infers types from schemas and interfaces

Breaking Changes: None - this is a patch release focusing on internal code quality improvements.

v1.5.1 - Feature Consolidation & Dynamic Versioning

🎯 New Features

Feature Consolidation Architecture

Generate consolidated feature packages with modular sub-services and provider aggregation patterns.

Sub-Services for Feature Packages (includeSubServices option)

NX Unable to resolve @samuelho-dev/monorepo-library-generator:feature.

Unable to resolve local plugin with import path @samuelho-dev/monorepo-library-generator
Pass --verbose to see the stacktrace.

Generates organized service directory structure:

feature-cluster/
└── src/lib/server/services/
    ├── index.ts              # Barrel export
    ├── backup/              # Individual sub-services
    ├── checkpoint/          # Each with service.ts, layers.ts
    ├── config/              # errors.ts, types.ts, index.ts
    ├── credentials/
    └── discovery/

Provider Consolidation for Infra Packages (consolidatesProviders option)

NX Unable to resolve @samuelho-dev/monorepo-library-generator:infra.

Unable to resolve local plugin with import path @samuelho-dev/monorepo-library-generator
Pass --verbose to see the stacktrace.

Generates aggregated infrastructure layer:

// index.ts - Re-export all providers
export { Kubectl, Talos, Terraform, ArgoCD }
export { ClusterInfrastructureLive } from "./lib/layers"
export { ClusterOrchestrator } from "./lib/orchestrator"

// layers.ts - Merge all provider layers
export const ClusterInfrastructureLive = Layer.mergeAll(
  KubectlLive, TalosLive, TerraformLive, ArgoCDLive
)

// orchestrator.ts - Multi-provider coordination
export class ClusterOrchestrator extends Context.Tag("ClusterOrchestrator")<
  ClusterOrchestrator,
  { /* orchestration methods */ }
>() {}

Templates Added (10 new files):

• Sub-service templates: service, layers, errors, types, index
• Provider consolidation: index, layers, orchestrator
• Core generators: sub-services.ts, provider-consolidation.ts

Dynamic Version System

CLI and MCP server now dynamically read version from package.json instead of hardcoded values.

• Auto-generates src/version.ts during build via scripts/generate-version.mjs
• Version stays in sync across package.json, CLI output, and MCP server
• Added to prebuild script for automatic generation

🐛 Bug Fixes

Template Interpolation (src/generators/provider/templates/layers.template.ts)

• Fixed className interpolation using template literals instead of regular strings
• Now correctly generates StripeInternalError instead of literal ${className}InternalError

Build System

• Fixed TypeScript compilation errors (unused variables, incorrect Effect imports)
• Updated publish script to use test:ci for proper test execution
• All 166 files now compile successfully

Test Infrastructure

• Fixed test expectations to match actual template output
• Updated vitest.config.local.ts to include src/**/*.spec.ts
• Added fileParallelism: false to prevent NX graph conflicts
• Increased timeout to 30s for generator tests
• All 205 tests now passing

📊 Impact

Files Changed: 28 files

• Added: 11 files (+688 lines)
• Modified: 17 files (-23 lines)

Generator Enhancements:

• Feature generator: Sub-service architecture support
• Infra generator: Provider consolidation support
• Build system: Dynamic version management
• Template engine: Fixed interpolation bugs

🔧 Technical Details

Schema Updates:

• feature/schema.json: Added includeSubServices, subServices options
• infra/schema.json: Added consolidatesProviders, providers options

Core Generator Changes:

• core/feature.ts: Integrated sub-service generation
• core/infra.ts: Integrated provider consolidation with conditional index generation
• Concurrent file generation with Effect.forEach

Backward Compatibility: ✅ Fully backward compatible

• New options are optional (default: false)
• Existing generators work unchanged
• No breaking changes to templates or APIs

v1.5.0

Minor Changes

Dotfiles Architecture Fix & Workspace Initialization

Breaking Changes:

• Removed includeVSCodeSettings option from all generator schemas
• Libraries no longer generate workspace-level dotfiles (.editorconfig, .vscode/*)

New Features:

• CLI Command: init-workspace - Initialize workspace-level dotfiles at repository root
• MCP Tool: init_workspace - AI agents can now initialize workspace dotfiles via MCP protocol

Architectural Improvements:

• Clean separation between workspace-level dotfiles (created once at root) and library-level dotfiles (created per library)
• See migration guide in CHANGELOG.md

Provider Type Specialization

Added support for four provider integration patterns:

• SDK Wrapper (default) - For npm packages with TypeScript SDKs
• CLI Wrapper - For command-line tools (Docker, Git, etc.)
• HTTP/REST API - For REST APIs with authentication support
• GraphQL API - For GraphQL endpoints with query/mutation support

New Usage Examples:

# SDK Wrapper (default)
nx g @workspace:provider stripe --externalService="Stripe" --providerType=sdk

# CLI Wrapper
nx g @workspace:provider docker --externalService="Docker" --providerType=cli --cliCommand="docker"

# HTTP/REST API
nx g @workspace:provider acme-api --externalService="Acme API" --providerType=http --baseUrl="https://api.acme.com"

# GraphQL API
nx g @workspace:provider hasura --externalService="Hasura" --providerType=graphql --baseUrl="https://api.hasura.io/v1/graphql"

Comprehensive Effect.ts Patterns Audit

Documentation Improvements:

• Added control flow decision matrix (Effect.if/when/unless)
• Added Effect.all batch operations guide with concurrency patterns
• Expanded Effect running patterns section with clear decision matrix
• Added 400+ line "Decision Matrices & Quick Reference" section

Production Patterns:

• Stream Patterns: Added streamAll method to repository interface
• Queue Patterns: Already comprehensive (no changes needed)
• Observability: Added comprehensive Effect.tap success-path patterns
• Decision Matrices: Master decision trees for 6 categories

Test Coverage:
✅ All 205 tests passing
✅ Manual verification of generated libraries
✅ Workspace initialization tested

Impact:

• Developers can now generate providers for CLI tools, HTTP APIs, and GraphQL endpoints
• Production-ready code generation for all four patterns
• 100% backward compatible - existing SDK provider generation unchanged

v1.2.3 - Bundle Optimization for Contract Libraries

🌳 Bundle Optimization

This release introduces bundle optimization features for contract libraries, enabling better tree-shaking and smaller production bundles.

✨ New Features

• Separate Entity Files: Each entity is now generated in its own file for optimal tree-shaking
• Granular Package Exports: Package.json includes specific subpath exports for each entity
• Type-Only Imports: Zero-runtime-overhead type imports via dedicated /types export
• Comma-Separated CLI Syntax: Pass multiple entities easily: --entities=Product,ProductCategory,ProductReview

📦 Import Examples

// Granular imports (best for tree-shaking)
import { Product } from '@repo/contract-product/entities/product'

// Type-only imports (zero bundle impact)
import type { Product } from '@repo/contract-product/types'

// Barrel imports (convenience)
import { Product } from '@repo/contract-product/entities'

🔧 Fixed

• Fixed generators.json packaging for Nx generator discovery
• Fixed entity parameter parsing from CLI arguments
• Corrected package.json repository URL and bin path format

📝 Usage

# Install or update
npm install -g @samuelho-dev/monorepo-library-generator

# Generate contract library with multiple entities
mlg contract product --entities=Product,ProductCategory,ProductReview

🎯 Bundle Impact

Contract libraries now support:

• ✓ Separate entity files for tree-shaking
• ✓ Granular package.json exports per entity
• ✓ Type-only imports with zero runtime overhead
• ✓ Proper barrel files for convenience imports
