Sprint Challenge - Node.js & Express

Overview

The Sprint Challenge is an opportunity for you to demonstrate your mastery of the learning objectives from this sprint. You will build a complete web API that demonstrates your understanding of Node.js, Express, routing, middleware, and deployment.

Sprint Objectives

In this sprint challenge, you will demonstrate your proficiency in:

Node.js Core Features - Using Node.js to create server-side applications
Express Framework - Leveraging Express to build RESTful APIs
RESTful API Design - Implementing endpoints that follow REST conventions
Route Handling - Creating routes for different HTTP methods and resources
Middleware - Using both built-in and custom middleware for request processing
Error Handling - Implementing proper error handling middleware
Data Persistence - Working with data storage (typically using in-memory data for this challenge)
API Testing - Testing API endpoints to ensure proper functionality

Challenge Preview

You'll be building a RESTful API for managing a collection of resources. The challenge will typically include:

Setting up an Express server
Creating CRUD (Create, Read, Update, Delete) endpoints
Implementing proper error handling
Using middleware for common tasks
Testing your API with Postman or similar tools
Documenting your API endpoints

The specific domain (users, products, etc.) will be provided in the challenge instructions.

Project Requirements

Build a complete RESTful API
Implement proper routing and middleware
Use environment variables for configuration
Deploy the application to a hosting service
Write comprehensive tests
Document the API endpoints
Follow best practices for error handling
Implement proper security measures

Code Example

Your sprint challenge solution will likely include code similar to this structure:

// server.js
const express = require('express');
const helmet = require('helmet');
const cors = require('cors');

const resourceRouter = require('./resources/resource-router');
const errorHandler = require('./middleware/error-handler');

const server = express();

// Global middleware
server.use(express.json());
server.use(helmet());
server.use(cors());

// Router middleware
server.use('/api/resources', resourceRouter);

// Root endpoint
server.get('/', (req, res) => {
  res.json({ api: 'running' });
});

// Error handling middleware (must be last)
server.use(errorHandler);

module.exports = server;
