@brookslybrand, the react-19 branch's default template does not work if you set ssr: false in react-router.config.ts. Perhaps not an issue with the template and simply an incompatibility between react-router and react@19? I see this issue: remix-run/react-router#12138

This concerns react-compiler that is introduced with React 19. The below file

react-router-templates/node-postgres/tsconfig.node.json

Line 11 in c1da1b6

"moduleResolution": "NodeNext"

in official templates use moduleResolution: NodeNext which causes issues when you try to add react compiler using vite-react-babel plugin in vite.config.ts. Typescript complains that plugins babel() is not a function.
Using moduleResolution: Bundler solves this issue.

Here's a working example of changes required to enable react-compiler for RR7: forge42dev/base-stack#20
I was following the same link when I hit the above error and its resolution.

Thanks @yoh-000 for pointing that out. Per the last comment you need to set NODE_ENV=production when running build

"build": "NODE_ENV=production react-router build"

We're looking into if there are better defaults we need to set, but in the meantime this will get you unblocked.

I've updated the appropriate templates to reflect this. I plan to setup a SPA template soon which will have this setup properly by default

I'm going to go ahead and merge this. @SiddharthPant please feel free to open up another issue about the "moduleResolution: Bundler" suggestion/issue. It may be something we want to change, but I'm going to let @pcattori or someone else on the team address that

@SiddharthPant never mind, I went ahead and updated all remaining tsconfig files in #30
