How to use nodejs-backend-patterns on Cursor

AI-first code editor with Composer

Prerequisites

Before installing skills in Cursor, ensure your development environment meets these requirements:

›Cursor installed and configured on your machine
›Node.js 16+ with npm — verify with node --version
›Active project directory where you want to add nodejs-backend-patterns

Run the install command

Execute the skills CLI command in your project's root directory to begin installation:

$npx skills add https://github.com/wshobson/agents --skill nodejs-backend-patterns

Fetches nodejs-backend-patterns from wshobson/agents and configures it for Cursor.

Select Cursor when prompted

The CLI shows a list of agents. Use arrow keys and space to select Cursor:

◆ Which agents do you want to install to?

│ ── Universal (.agents/skills) ────────────────

│ · Cline · Codex · Goose · Windsurf

│ ●Cursor(selected)

│ · Cursor · Aider · Continue

Verify installation

Confirm successful installation by checking the skill directory location:

.cursor/skills/nodejs-backend-patterns

Restart Cursor to activate nodejs-backend-patterns. Access via /nodejs-backend-patterns in your agent's command palette.

Security Notice

We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.

Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

Core Frameworks

Express.js - Minimalist Framework

Basic Setup:

import express, { Request, Response, NextFunction } from "express"; import helmet from "helmet"; import cors from "cors"; import compression from "compression"; const app = express(); // Security middleware app.use(helmet()); app.use(cors({ origin: process.env.ALLOWED_ORIGINS?.split(",") })); app.use(compression()); // Body parsing app.use(express.json({ limit: "10mb" })); app.use(express.urlencoded({ extended: true, limit: "10mb" })); // Request logging app.use((req: Request, res: Response, next: NextFunction) => { console.log(`${req.method} ${req.path}`); next(); }); const PORT = process.env.PORT || 3000; app.listen(PORT, () => { console.log(`Server running on port ${PORT}`); });

Fastify - High Performance Framework

Basic Setup:

import Fastify from "fastify"; import helmet from "@fastify/helmet"; import cors from "@fastify/cors"; import compress from "@fastify/compress"; const fastify = Fastify({ logger: { level: process.env.LOG_LEVEL || "info", transport: { target: "pino-pretty", options: { colorize: true }, }, }, }); // Plugins await fastify.register(helmet); await fastify.register(cors, { origin: true }); await fastify.register(compress); // Type-safe routes with schema validation fastify.post<{ Body: { name: string; email: string }; Reply: { id: string; name: string }; }>( "/users", { schema: { body: { type: "object", required: ["name", "email"], properties: { name: { type: "string", minLength: 1 }, email: { type: "string", format: "email" }, }, }, }, }, async (request, reply) => { const { name, email } = request.body; return { id: "123", name }; }, ); await fastify.listen({ port: 3000, host: "0.0.0.0" });

Architectural Patterns

Pattern 1: Layered Architecture

Structure:

src/ ├── controllers/ # Handle HTTP requests/responses ├── services/ # Business logic ├── repositories/ # Data access layer ├── models/ # Data models ├── middleware/ # Express/Fastify middleware ├── routes/ # Route definitions ├── utils/ # Helper functions ├── config/ # Configuration └── types/ # TypeScript types

Controller Layer:

// controllers/user.controller.ts import { Request, Response, NextFunction } from "express"; import { UserService } from "../services/user.service"; import { CreateUserDTO, UpdateUserDTO } from "../types/user.types"; export class UserController { constructor(private userService: UserService) {} async createUser(req: Request, res: Response, next: NextFunction) { try { const userData: CreateUserDTO = req.body; const user = await this.userService.createUser(userData); res.status(201).json(user); } catch (error) { next(error); } } async getUser(req: Request, res: Resp
