Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/aj-geddes/useful-ai-prompts --skill nodejs-express-server- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads nodejs-express-server automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

Node.js Express Server
Table of Contents
Overview
Create robust Express.js applications with proper routing, middleware chains, authentication mechanisms, and database integration following industry best practices.
When to Use
- Building REST APIs with Node.js
- Implementing server-side request handling
- Creating middleware chains for cross-cutting concerns
- Managing authentication and authorization
- Connecting to databases from Node.js
- Implementing error handling and logging
Quick Start
Minimal working example:
const express = require("express");
const app = express();
const PORT = process.env.PORT || 3000;
// Middleware
app.use(express.json());
app.use(express.urlencoded({ extended: true }));
// Routes
app.get("/health", (req, res) => {
res.json({ status: "OK", timestamp: new Date().toISOString() });
});
// Error handling
app.use((err, req, res, next) => {
console.error(err.stack);
res.status(err.status || 500).json({
error: err.message,
requestId: req.id,
});
});
app.listen(PORT, () => {
console.log(`Server running on port ${PORT}`);
});

Best Practices
✅ DO
- Use middleware for cross-cutting concerns
- Implement proper error handling
- Validate input data before processing
- Use async/await for async operations
- Implement authentication on protected routes
- Use environment variables for configuration
- Add logging and monitoring
- Use HTTPS in production
- Implement rate limiting
- Keep route handlers focused and small
❌ DON'T
- Handle errors silently
- Store sensitive data in code
- Use synchronous operations in routes
- Forget to validate user input
- Implement authentication in route handlers
- Use callback hell (use promises/async-await)
- Expose stack traces in production
- Trust client-side validation only

Popular backend & apis skills
find-skills
vercel-labs/skills
Helps users discover and install agent skills when they ask questions like "how do I do X", "find a skill for X", "is there a skill that can...", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.
entra-app-registration
microsoft/azure-skills
Guides Microsoft Entra ID app registration, OAuth 2.0 authentication, and MSAL integration. USE FOR: create app registration, register Azure AD app, configure OAuth, set up authentication, add API permissions, generate service principal, MSAL example, console app auth, Entra ID setup, Azure AD authentication. DO NOT USE FOR: Key Vault secrets (use azure-keyvault-expiration-audit), general Azure resource security guidance.
google-agents-cli-adk-code
google/agents-cli
This skill should be used when the user wants to "write agent code", "build an agent with ADK", "add a tool", "create a callback", "define an agent", "use state management" — in a project that needs ADK (Agent Development Kit) API patterns and code examples. It provides a quick reference for agent types, tool definitions, orchestration patterns, callbacks, state management, the graph Workflow API, and reference recipes to study. Do NOT use for scaffolding (use google-agents-cli-scaffold) or deployment (use google-agents-cli-deploy).
embedded-captions
heygen-com/hyperframes
Add captions or subtitles to an existing single-subject talking-head video without editing the footage. Use for plain verbatim captions, cinematic captions embedded behind the subject, VFX captions, “炸/特效/酷炫字幕,” or a named identity from the 35-style catalog. Route by visual identity, not by backend engine. The quiet anchor rail is the default; embed every word only when the user explicitly wants a fully cinematic treatment. The workflow runs locally end to end, including transcription and subject matting; split multi-shot footage before applying it.
entra-agent-id
