Chapters
00:00 - Introduction and Overview
The hosts introduce the episode’s topic: managing multiple data sources in GraphQL. They welcome Anthony Campolo, a developer advocate for StepZen. Anthony briefly discusses his background, transitioning from music teaching to tech through a bootcamp and involvement with RedwoodJS. He explains how his work with RedwoodJS led to his current role at StepZen. The conversation touches on the basics of GraphQL, describing it as a query language for APIs that standardizes how to interact with various data sources. Anthony highlights the advantages of GraphQL over REST APIs, particularly in its ability to request only the specific data needed.
02:56 - Deep Dive into StepZen and GraphQL
Anthony begins a demonstration of StepZen, showing how to create a simple GraphQL schema and deploy an endpoint. He explains the process of connecting to different APIs, such as the Rick and Morty API and a REST API, using StepZen’s custom directives. The demo showcases how StepZen simplifies the process of combining multiple data sources into a single GraphQL endpoint without the need to write complex resolvers. Anthony discusses the configuration of API keys and how StepZen handles authentication. He also introduces the StepZen GraphQL Studio, a tool that provides pre-built API schemas and allows for instant deployment of GraphQL endpoints without requiring a StepZen account.
27:57 - Frontend Integration and Real-World Application
The discussion shifts to how StepZen can be integrated into frontend applications. Anthony demonstrates a SvelteKit example, showing how to connect a frontend to a StepZen endpoint using simple fetch requests. He explains the process of writing GraphQL queries and how they can be easily incorporated into frontend components. The conversation touches on the concept of “Fullstack Jamstack” and how tools like StepZen, combined with frontend frameworks and services like Supabase, enable developers to create full-stack applications without managing complex backend infrastructure. Anthony also discusses StepZen’s pricing model, emphasizing its current free tier and future plans for enterprise features.
42:56 - Perfect Picks and Closing Thoughts
The hosts and Anthony share their “perfect picks” - recommended resources, tools, or entertainment. Picks include a Netlify blog post about building database-driven Jamstack sites, the TV show “The Morning Show”, Prisma ORM, rechargeable batteries for Xbox controllers, developer Discord communities, and the TV show “Arrested Development”. The episode concludes with Anthony encouraging listeners to explore StepZen and offering to chat about various tech-related topics, including career change advice based on his own journey.
