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…

Click here to share this article on LinkedIn » 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…
