docs: fix import path for routeTree in manual.md

[spinner5]

The documentation says following:

Create the following files:

src/routes/__root.tsx (with two '_' characters)
src/routes/index.tsx
src/routes/about.tsx
src/main.tsx

This is problem because the routeTree.gen is generated in root of the src folder.

Walkthrough

Updated the import path for routeTree from ./routeTree.gen to ../routeTree.gen in two locations within the React Router manual documentation. This adjusts module resolution to reference the file from the parent directory.

Thanks for this. Not sure I follow what we are correcting here.

The section of the guide is specific to src/main.tsx and the routetree is generated in the same src folder src/routetree.gen.ts. The path of ./routetree.gen.ts is correct relative to the main.tsx file.

Hi, I'm sorry for wasting your time with this. I missread that main.tsx was inside routes folder... that's why I was having issues getting this working. Brainfog you know :D Closed this.
