Caching, up-front

Caching is essential in REST APIs, and for many, it is often an afterthought. Including caching in the design process requires your team to think more carefully about your models, and how to structure the resource layer. Ask me how I know... I've spend the last week attempting to speed up a data-intensive analytics portal.

Pre-fetching data is far more performant and provides a better end-user experience in a web application, especially if the underlying API utilises caching most efficiently. If you need a little refresher, check out this great article from Speakeasy and, of course, our article Design Basics: Cacheability.

The API Roundup

API News, links, and tools from around the web

OpenAPI Fundamentals

The Linux Foundation offers some fantastic courses; however, I missed that they have a free 90-minute course to Learn the basics of the OpenAPI Specification. You'll explore how to write, use, and extend OpenAPI documents to streamline API development and integration. Worth checking out if you're new to OpenAPI.

GraphQLConf 2025

GraphQL Conf has dropped the schedule for their conference in Amsterdam in September. The lineup is quite interesting, featuring GraphQL at Meta, GraphQL performance issues at Netflix, and addressing GraphQL's biggest mistakes, such as not being REST 😉.

Hono Comes to NodeJS

Hone creator Yusuke Wada talks us through using only Web Standards to build the web framework Hono and running it on Cloudflare Workers, Deno, and Bun. Yusuke details the challenges of bringing Hono to Node and how they were overcome. I love Hono and am super excited to see it come to Node.

Ktor 3.2.0 Is Now Available

If you haven't heard of Ktor before, it's a modern web framework in Kotlin that focuses on asynchronous programming features and intuitive, imperative flow. Honestly, I am not doing it justice. You should be checking it out. They recently dropped a new release with support for HTMX.

JSON evolution in Go

Go's encoding/json v2 introduces a more robust and flexible API for JSON handling. It offers enhanced performance, streaming-friendly functions like MarshalWrite, UnmarshalRead and customisable options for formatting and field behaviour, enabling developers to create more efficient and maintainable web APIs.

All about Mocking, with Wiremock's Tom Akehurst

Mocking is one of those things that started out as a simple idea, and has evolved to support an incredible amount of developer use cases over the years. In this episode of the Podcast, Tom from Wiremock chats with Phil about what mocking is, strategies for not littering OpenAPI doc with mocking details, and ways to keep api dev teams empowered by mocking, instead of hampered by it.
