Build Issues

TypeScript Path Resolution Errors:

# Clear TypeScript cache
rm -rf **/*.tsbuildinfo
pnpm run clean
pnpm run build

SWC Build Failures:

# Ensure SWC is installed
pnpm add -D @swc/cli @swc/core

# Clean and rebuild
pnpm run clean
pnpm run build

Workspace Dependency Issues:

# Reinstall workspace dependencies
pnpm install --force
pnpm run build

Missing Modules or Types:

Ensure you have built @mcp-prompts/core first
Check that all dist/ directories are up to date
If you change the shared config or move files, clean all dist/ directories and rebuild

Runtime Issues

Common Issues:

If you see errors about missing modules or types, ensure you have built @mcp-prompts/core first and that all dist/ directories are up to date.
If you change the shared config or move files, clean all dist/ directories and rebuild.

Architecture

Hexagonal Architecture (Ports & Adapters)

MCP Prompts follows a clean hexagonal architecture pattern:

Core: Pure domain logic without infrastructure dependencies
Ports: Interfaces defined in core package
Adapters: Infrastructure implementations in adapter packages
Apps: Composition and configuration in apps folder
