JSMP 29: Daria Poliakova & Ihor Maistrenko on Auto-Generated TypeScript API Clients

🎙️ JSMP 29: Daria Poliakova & Ihor Maistrenko on Auto-Generated TypeScript API Clients

In this episode of JavaScript Master Podcast, we dive into the world of auto-generated TypeScript API clients with two seasoned developers: Daria Poliakova and Ihor Maistrenko.

Auto-generated API clients help you save time, avoid duplication and improve type safety by generating fully typed client code directly from API specifications. This approach can dramatically reduce boilerplate and keep your frontend in sync with backend changes — a major boost to productivity for modern TypeScript development workflows. 

🎧 What you’ll learn in this episode:

• What auto-generated API clients actually are and why they matter in TypeScript projects

• The real problems they solve compared to hand-written service layers

• Tools and standards used in client generation (OpenAPI, Swagger, codegen tools)

• Typical workflows — from API definition to a fully typed client

• How to handle authentication, headers, errors, and dynamic regeneration

• Advantages, pitfalls, and best practices for teams adopting this approach

• Why modern developers should consider using auto-generated clients in 2026

We also explore the human side of software development, including how definitions of being a great developer evolve over time and which non-technical skills have had the biggest impact on their careers.
