Day 4

Code Generation at Scale

Generate complete features, not just snippets — REST endpoints, DB schemas, and CLI tools.

0 / 5 tasks

Thinking beyond snippets

Claude can generate entire modules, not just individual functions. The key is giving it clear requirements and context. Describe what you need, the tech stack, and any constraints.

Generate a REST endpoint

bash

claude
> Generate a FastAPI endpoint POST /api/users that:
> - Accepts name, email, password fields
> - Validates the email format
> - Hashes the password with bcrypt
> - Saves to SQLAlchemy User model
> - Returns 201 with the created user (excluding password)
> - Handles duplicate email with 409

Generate a CLI tool

bash

claude
> Build a Python CLI tool using Click that:
> - Has a command `process` that takes a CSV file path
> - Reads the CSV, removes duplicate rows
> - Outputs statistics: total rows, removed duplicates
> - Writes cleaned data to output.csv
> - Has --verbose flag for detailed logging

Generate Docker/config files

bash

claude
> Generate a production-ready Dockerfile for a Python FastAPI app that:
> - Uses Python 3.12 slim
> - Installs dependencies as a separate layer
> - Runs as non-root user
> - Uses gunicorn with uvicorn workers
> - Exposes port 8000
> Also generate a docker-compose.yml with postgres and redis

Practice Tasks

0 / 5

Generate a REST endpoint medium

Write detailed requirements for a CRUD endpoint and have Claude generate the complete implementation.

Generate a database schema medium

Describe a domain (e.g. a blog, a shop) and have Claude generate the SQLAlchemy models with relationships.

Build a CLI tool medium

Have Claude create a Click-based CLI for any task you frequently do manually.

Generate a Dockerfile easy

Have Claude create a production Dockerfile for your project with security best practices.

Generate configuration medium

Have Claude generate nginx, supervisord, or systemd service config for your app.
