Project Status

Node.js/TypeScript project initialized with npm, tsconfig, and Jest (ts-jest). Source code implementation is pending.

Build Commands

npm install        # install dependencies
npm run build      # compile TypeScript → dist/ via tsc

Test Commands

npm test                          # run full Jest test suite
npm test -- path/to/file.test.ts  # run a single test file
npm test -- -t "test name"        # run a single named test

Development Commands

npm run dev    # tsx watch src/server.ts (TypeScript watch mode)
npm start      # node dist/server.js (production build)

Architecture Notes

Purpose: An API service for counting words in text input.
Stack: Node.js + TypeScript (CommonJS modules, tsc build, tsx for dev watch).
HTTP framework: Express (express + @types/express).
Key design decisions still to make: authentication strategy, request/response format (REST vs. GraphQL), deployment target.

Code Style

TypeScript strict mode is enabled ("strict": true in tsconfig.json). No linter or formatter configured yet. Document here once a stack is chosen (e.g., ESLint/Prettier).
