Open api typescript error about middleware

Or how about this?

import 'hono'

declare module 'hono' {
  interface ContextVariableMap {
    result: string
  }
}

I don't think this is a problem that can be solved by changing the Hono code.

Hi @mandado

That is probably not a bug. It is possible that @hono/zod-openapi and hono are referring to different hono files. Please reinstall and try again.

This problem happens when I create a file like app.d.ts and includes on my tsconfig with the content:

declare module 'hono' {
  interface ContextVariableMap {
    result: string
  }
}

seems like the typescript it not extending the interface ContextVariableMap .

the solution for that is:

export * from 'hono';

declare module 'hono' {
  interface ContextVariableMap extends Record<string, string> {
    result: string
  }
}
