Can someone explain how Claude Code can instantly determine what file I have open and what lines I have selected in VS Code even if it's just running in a VS Code terminal instance, yet I cannot for the life of me get OpenCode to come anywhere close to that same experience?
The OpenCode docs suggest its possible, but it only works with their extension (not in an already open VS Code terminal) with a very specific keyboard shortcut and only barely at that.
If you're using an alpha library then that's on you for not expecting breaking changes. They have plenty of 1.0+ libraries that do not receive any breaking changes between major releases and have remained stable for well over a year.
Also, you're just wrong? You literally cannot serve RSC components _at all_ even in TanStack Start yet. Even when support for them is added it will be opt-in for only certain kinds of RPC functions and they will work slightly differently than they do in Next.js app router(where they are the default everywhere). RPC != RSC.
Plus you can always stick to using TanStack Router exclusively (zero server at all) and you never will even have to worry about anything to do with RSCs...
I would highly recommend just checking out TanStack Router/Start instead. It fills a different niche, with a slightly different approach, that the Next.js app router just hasn't prioritized enabling anymore.
What app router has become has its ideal uses, but if you explicitly preferred the DX of the pages router, you might enjoy TanStack Router/Start even more.
If you're happy with tRPC and don't need proper REST functionality it might not be worth it.
However, if you want to lean that direction where it is a helpful addition they recently added some tRPC integrations that actually let you add oRPC alongside an existing tRPC setup so you can do so or support a longer term migration.
ts-rest doesn't see a lot of support these days. It's lack of adoption of modern tanstack query integration patterns finally drove us look for alternatives.
Luckily, oRPC had progressed enough to be viable now. I cannot recommend it over ts-rest enough. It's essentially tRPC but with support for ts-rest style contracts that enable standard OpenAPI REST endpoints.
