Integrating Hono.js with tRPC in Next.js: Routing and Context Considerations

I want to combine Hono.js with tRPC. I followed the guide on the 3rd party middleware made by hono for a tRPC server, and now I have set up the hono tRPC server 3rd party middleware similar to the code below:
import { Hono } from 'hono'
import { trpcServer } from '@hono/trpc-server' // Deno 'npm:@hono/trpc-server'
import { appRouter } from './router'

const app = new Hono()

app.use(
  '/trpc/*',
  trpcServer({
    router: appRouter,
  })
)

export default app


I used Hono.js as a web server because I wanted to achieve the light and ultrafast web server capabilities of Hono.js.

I got confused with the documentation for tRPC and Hono.js because, with tRPC, they also have their own API route setup in Next.js specifically, the route at src/app/api/trpc/[trpc]/route, and Hono.js also has its own API route setup in Next.js namely, the route at src/app/api/[[...route]]/route.ts. So, I don’t know which one I should follow to use the 3rd party library created by Hono.js, which is @hono/trpc-server.

Now, where should I place this code in Next.js? Should it go in app/api/[[...route]]/route.ts or in app/api/trpc/[trpc]/route.ts?

Also, what is the best approach regarding context—should I use the tRPC context or the Hono.js context?
