Node.js & Express Code Snippets

Production-ready snippets for Node.js, Express, TypeScript, ESM, and Modern Backend Development.
_{A product from bluebuff.in}

Overview

Node.js & Express Code Snippets supercharges backend development in Visual Studio Code. Packed with battle-tested snippets for modern JavaScript, TypeScript, ES Modules (ESM), CommonJS (CJS), database ORMs, security middleware, and Clean Architecture patterns—with precision tab stops and exit cursor positions ($0).

Highlights

TypeScript & Modern ESM First

Write typed Express handlers (Request, Response, NextFunction, ErrorRequestHandler), type-safe middleware, and choose seamlessly between ES Modules (import) and CommonJS (require()).

Production Security & Middleware

Instant boilerplates for JWT authentication, Zod & Joi schema validation, Helmet security headers, CORS configuration, Rate Limiting, and Morgan logging.

Databases & ORMs

Pre-built snippets for Prisma Client & queries, Mongoose schemas & aggregation pipelines, Sequelize models, PostgreSQL connection pools (pg.Pool), and Redis clients.

Modern Node.js APIs

Native node:test runner, native fetch with AbortController timeout handling, node:fs/promises, worker threads, crypto UUIDs, and clustering.
