How to Use ChatGPT for Coding

ChatGPT is one of the most accessible tools for developers learning to work with AI. Whether you are writing your first function or architecting a complex system, the key to getting useful code from ChatGPT is how you prompt it. Start by telling it your language, framework, and what you are building. Instead of asking "write a login page," try "write a Next.js 14 login page using server actions, Zod validation, and Tailwind CSS with error handling for invalid credentials." The more specific your prompt, the closer the output is to production-ready code.

A practical workflow looks like this: start with pseudocode or a description of what you need, let ChatGPT generate a first draft, then iterate. Ask it to add error handling, write tests, or refactor for performance. Use follow-up prompts like "now add TypeScript types" or "handle the edge case where the API returns a 429." This iterative approach works far better than trying to get perfect code in one shot. For debugging, paste the error message along with the relevant code and explain what you expected versus what happened.

ChatGPT has limitations worth knowing. It can hallucinate APIs that do not exist, produce outdated patterns for fast-moving frameworks, and struggle with very large codebases where context is spread across many files. For large projects, consider pairing ChatGPT with tools like Cursor or Claude Code that can read your entire repo. Save prompts that work well for you — building a personal prompt library is the fastest way to compound your productivity gains over time.
