chore: Drop Node 16 support, require Node 18+

facundofarias · claude · facundofarias · commit 55a01ce59120 · 2025-11-11T08:46:35.000+01:00
Simplify Node version support by requiring Node 18+ for both runtime and development tools. Node 18 is the active LTS and dev tools (ESLint 9.x, Vitest) require Node 18+. Changes: - Update package.json engines from >=16.0.0 to >=18.0.0 - Remove Node 16.x from CI test matrix (now 18.x, 20.x, 22.x) - Remove conditional skip for lint/test on Node 16.x in CI - Update all documentation (README, USER_GUIDE, CLAUDE.md) - Simplify prerequisite messaging Rationale: - Dev tools (ESLint 9, Vitest) require Node 18+ - Node 18 is active LTS (maintenance until 2025-10-31) - Simplifies CI and reduces complexity - Most Claude Desktop/Code installations use Node 18+ anyway 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

 ## Important: Node Version
 
-**Runtime**: Requires Node.js >=16.0.0 (specified in package.json engines). The server uses node-fetch for HTTP requests to ensure compatibility with Node 16+, which is commonly used by Claude Desktop/Code installations.
-
-**Development**: Requires Node.js >=18.0.0 for development tools (ESLint 9.x requires Node 18.18+). If you're on Node 16, you can still build and test, but skip linting with `npm run build && npm run type-check`.
