Romuald Członkowski 211ae72f96 feat: add community nodes support (Issues #23, #490) (#527) 
* feat: add community nodes support (Issues #23, #490)

Add comprehensive support for n8n community nodes, expanding the node
database from 537 core nodes to 1,084 total (537 core + 547 community).

New Features:
- 547 community nodes indexed (301 verified + 246 npm packages)
- `source` filter for search_nodes: all, core, community, verified
- Community metadata: isCommunity, isVerified, authorName, npmDownloads
- Full schema support for verified nodes (no parsing needed)

Data Sources:
- Verified nodes from n8n Strapi API (api.n8n.io)
- Popular npm packages (keyword: n8n-community-node-package)

CLI Commands:
- npm run fetch:community (full rebuild)
- npm run fetch:community:verified (fast, verified only)
- npm run fetch:community:update (incremental)

Fixes #23 - search_nodes not finding community nodes
Fixes #490 - Support obtaining installed community node types

* fix: add community fields to node-repository-outputs test mockRows

Update all mockRow objects in the test file to include the new community
node fields (is_community, is_verified, author_name, etc.) to match the
updated database schema.

* fix: add community fields to node-repository-core test mockRows

Update all mockRow objects and expected results in the core test file
to include the new community node fields, fixing CI test failures.

* fix: separate documentation coverage tests for core vs community nodes

Community nodes (from npm packages) typically have lower documentation
coverage than core n8n nodes. Updated tests to:
- Check core nodes against 80% threshold
- Report community nodes coverage informatively (no hard requirement)

* fix: increase bulk insert performance threshold for community columns

Adjusted performance test thresholds to account for the 8 additional
community node columns in the database schema. Insert operations are
slightly slower with more columns.

* fix: make list-workflows test resilient to pagination

The "no filters" test was flaky in CI because:
- CI n8n instance accumulates many workflows over time
- Default pagination (100) may not include newly created workflows
- Workflows sorted by criteria that push new ones beyond first page

Changed test to verify API response structure rather than requiring
specific workflows in results. Finding specific workflows is already
covered by pagination tests.

* ci: increase test timeout from 10 to 15 minutes

With community nodes support, the database is larger (~1100 nodes vs ~550)
which increases test execution time. Increased timeout to prevent
premature job termination.

Database Layer Unit Tests

This directory contains comprehensive unit tests for the database layer components of n8n-mcp.

Test Coverage

node-repository.ts - 100% Coverage ✅

  • saveNode method with JSON serialization
  • getNode method with JSON deserialization
  • getAITools method
  • safeJsonParse private method
  • Edge cases: large JSON, boolean conversion, invalid JSON handling

template-repository.ts - 80.31% Coverage ✅

  • FTS5 initialization and fallback
  • saveTemplate with sanitization
  • getTemplate and getTemplatesByNodes
  • searchTemplates with FTS5 and LIKE fallback
  • getTemplatesForTask with task mapping
  • Template statistics and maintenance operations
  • Uncovered: Some error paths in FTS5 operations

database-adapter.ts - Tested via Mocks

  • Interface compliance tests
  • PreparedStatement implementation
  • Transaction support
  • FTS5 detection logic
  • Error handling patterns

Test Strategy

The tests use a mock-based approach to:

  1. Isolate database operations from actual database dependencies
  2. Test business logic without requiring real SQLite/sql.js
  3. Ensure consistent test execution across environments
  4. Focus on behavior rather than implementation details

Key Test Files

  • node-repository-core.test.ts - Core NodeRepository functionality
  • template-repository-core.test.ts - Core TemplateRepository functionality
  • database-adapter-unit.test.ts - DatabaseAdapter interface and patterns

Running Tests

# Run all database tests
npm test -- tests/unit/database/

# Run with coverage
npm run test:coverage -- tests/unit/database/

# Run specific test file
npm test -- tests/unit/database/node-repository-core.test.ts

Mock Infrastructure

The tests use custom mock implementations:

  • MockDatabaseAdapter - Simulates database operations
  • MockPreparedStatement - Simulates SQL statement execution
  • Mock logger and template sanitizer for external dependencies

This approach ensures tests are fast, reliable, and maintainable.
