Why add Node.js rules to your CLAUDE.md?

Node.js backends have no single dominant framework — Express, Fastify, NestJS, and Koa all have different patterns. A Node.js CLAUDE.md tells Claude which framework you use, how you structure middleware, how errors are handled and propagated, and what your logging setup looks like. Without it, Claude often generates inconsistent code that mixes patterns from different frameworks.
