Integrate APIs with StepZen GraphQL Studio | Frontend Horse
Published:
Anthony Campolo demonstrates how to integrate multiple APIs into a unified GraphQL API using StepZen, showcasing its capabilities for simplifying backend development.
Episode Summary
In this episode, Anthony Campolo guides the host through using StepZen, a GraphQL API gateway service. They begin by setting up a basic StepZen project, connecting to various APIs including a REST API, a GraphQL API, and a database. Anthony explains how StepZen simplifies the process of integrating multiple data sources into a single GraphQL endpoint. They explore creating mutations, working with Redwood.js to set up a backend, and deploying to Netlify. The episode culminates with a demonstration of StepZen’s GraphQL Studio, showcasing pre-built integrations with popular services like Google’s Natural Language API and dev.to. Throughout, Anthony emphasizes how StepZen can empower frontend developers by providing easier access to backend capabilities, potentially expanding their full-stack abilities.
Chapters
00:00 - Introduction and StepZen Overview
Anthony Campolo is introduced as the guest for the last Frontend Horse live stream of the year. He begins by explaining what StepZen is - a GraphQL API gateway that sits between different services. Anthony describes how StepZen can take various backends (REST APIs, databases, or even other GraphQL APIs) and turn them into a unified GraphQL API. He emphasizes the simplicity of StepZen’s approach, where developers write schemas and queries without needing to write resolvers. The conversation touches on the benefits of this approach for both experienced developers and beginners in the field.
04:34 - Setting Up a Basic StepZen Project
The stream moves into a practical demonstration, starting with setting up a basic StepZen project. They clone a boilerplate repository and install the StepZen CLI. Anthony guides the host through the structure of the project, explaining the purpose of key files like index.graphql and test.graphql. They run the StepZen start command to deploy a simple endpoint with mock data. This section provides a hands-on introduction to the basics of working with StepZen, showing how quickly a GraphQL API can be set up and deployed.
27:02 - Integrating REST and GraphQL APIs
Anthony leads the demonstration of integrating different types of APIs into the StepZen project. They start by connecting to a REST API (JSONPlaceholder) to fetch user data. Anthony explains the process of creating a GraphQL schema that maps to the REST endpoint. They then move on to integrating a GraphQL API, using the Rick and Morty API as an example. This section showcases StepZen’s ability to work with diverse data sources and how it simplifies the process of combining them into a single GraphQL endpoint.
42:24 - Working with Databases: Superbase and Railway
The stream progresses to demonstrate how to connect databases to the StepZen project. They start with Superbase, setting up a simple database and table. Anthony guides through the process of creating mutations to write data to the database. They then explore using Railway to quickly spin up a PostgreSQL database. This section highlights StepZen’s flexibility in working with different database solutions and how it can simplify database operations through GraphQL.
56:38 - Redwood.js Integration and Netlify Deployment
Anthony introduces Redwood.js, explaining its role as a full-stack JavaScript framework. They create a new Redwood project, set up a database schema using Prisma, and demonstrate how to create and use an admin interface. The focus then shifts to deploying the Redwood backend to Netlify as a serverless function. This chapter showcases how StepZen can work with more complex backend setups and integrate them into its GraphQL API.
92:37 - Exploring StepZen’s GraphQL Studio
In the final section, Anthony introduces StepZen’s GraphQL Studio, a feature that provides pre-built integrations with popular APIs. They explore integrations with Google’s Natural Language API and dev.to, demonstrating how to quickly set up and use these services. Anthony explains how developers can chain queries using StepZen’s @sequence directive, allowing for complex operations like sentiment analysis on blog comments. This chapter highlights the power and flexibility of StepZen in rapidly prototyping and building complex API integrations.
109:31 - Conclusion and Wrap-up
The stream concludes with a summary of what was covered and the potential applications of StepZen. Anthony emphasizes how StepZen can empower frontend developers to work more effectively with backend services. The host thanks the audience for their participation throughout the year, as this was the last stream of 2021. They discuss the growth of the Frontend Horse community and express excitement for future streams and projects in the coming year.
