A beginner-friendly guide to setting up a TypeScript project with Node.js from scratch. Covers installing TypeScript and Node type definitions, configuring tsconfig.json with key compiler options (rootDir, outDir, esModuleInterop, noImplicitAny, etc.), and setting up npm scripts for hot-reloading in development (using ts-node and nodemon), production builds (using rimraf and tsc), and production startup. Also briefly touches on testing approaches (stateless vs. stateful/Given-When-Then with jest-cucumber) and points to ESLint setup as a next step.
