We’ve been on a forked version of Relay v8 for a couple years. While the new versions had some neat features, nothing really compelled us to upgrade until now. Relay v11 (the one with hooks) is the biggest release since Relay Modern & it’s amazing. Aside from hooks, it lets…
GraphQL is great. Every GraphQL endpoint agrees to speak the same language of {data, errors} and that makes communication between servers easy. Now suppose two public APIs both speak GraphQL; what advantages can we leverage? Packages like graphql-tools make it easy to merge and stitch schemas together, which allows teams…
Scaling is relative. When Uber builds a scalable metric service, they build a proprietary database to resolve their queries. When Facebook scales a live feed, they build it to support millions of connected clients. This post is for the rest of us. …
Nobody likes a callback. It’s like a modern day equivalent of a GOTO statement. But how can we replace those pesky ones like click handlers? Chances are, you’ve refactored all all the easy ones into async/await statements, but there are still those pesky holdouts like DOM events, WebSockets, event emitters…
Back in late 2016 I wrote an article called GraphQL: Tips after a year in production. Since then, GraphQL started offering native subscriptions, Relay got so good you could replace Redux with Relay Modern, and I learned a few neat tricks along the way. I’ve also made a bunch of…

Recently, I screwed up and it resulted in a client getting a white screen when they used our app. Like most apps, we have an initial GraphQL query that fetches a ton, including a list of all your notifications. One of…
It’s been almost 2 years since I wrote Replacing Relay with Redux. Since then, Relay added subscriptions, a build-time compiler, a sensible mutations API, and a game-changing client schema. That puts me in an awkward position. On the one hand, we JavaScript developers get a bad wrap for declaring technology…
Subscriptions are really hard. That’s what makes them fun. It’s been a few months since GraphQL & Relay have supported them, and still examples are sparse. The worst part? The ones that do exist use patterns that will give you a headache if you try to implement them in your…
I finally added Relay Modern to my production build and I gotta say… I dig it. When Relay Classic was first released, I poked a lot of fun at it and even made my own client cache (with redux & subscriptions). The new version beautifully shuts me up. …
Recently, I built out billing and invoicing functionality for our small, open-source SaaS app (look out world, we got ourselves a business model!). The added functionality expanded the codebase by something like 45% and errors crept in like gophers to a carrot patch. Now, we’re already pretty good about reactively…
