I've been working on an application recently where I have decided to use TypeScript with ApolloServer. It's a microservice architecture, so Apollo's Federation works great for me. However, despite being written in TypeScript, Apollo just absolutely struggles to use it. Now, it could be me, I've never used this combination before, but it seems to me that Apollo just doesn't have the developer experience it should, in TypeScript at least.
I've used Apollo multiple times in my projects, it always has worked fine, until now. Now, I still really like Apollo and will continue to use it. However, let me explain just how frustrating it is to use it with TypeScript.
Hey there! I see you are using TypeScript! This is great. Go ahead and set up your project like normal. Whoops, resolvers don't work right. You need
IndexedString that takes an
IResolver type that you get from the
IndexedString needs a custom definition.
So now you need a special interface that goes into a type that allows you to pass in the
IResolvers. Implement all that, excellent it works.
Now you want to actually implement the resolvers? Great! Let's do that like normal except that every single parameter needs a type. Well, that makes sense except, I DON'T KNOW WHAT THAT TYPE IS! Okay, so we will just mark it as
any. Bad practice but it works so let's move on. I'm on the clock here okay?
Now you want custom directives? Nope you can't have them because they require special types as well apparently. Also they don't just go in your
federatedSchema, you have to create two schemas and merge them.
I guess this is a bit of a rant because I've been working on this for days now and I have almost nothing to show for it. It's incredibly frustrating, but I also wanted to raise a little awareness of this issue. Now, like I said, I haven't tried this combination before. I've used both TypeScript and Apollo, but never together. I could be missing something somewhere. But from what I see, people have been opening issues and complaining about this in the repository. I'm curious if any of you have managed to find their way through this particular swamp. If you have, please direct me toward some resources I can use. Otherwise, I may just drop TypeScript all together. (I really don't want to if I don't have to). Anyway, thanks for taking the time to read this. I hope your journey is easier than mine.
