Export Nitro routes for monorepo

[khako]

Hello !
I am using a pnpm monorepo with 2 packages, a Nuxt app and a Nitro app. How can I create a custom useFetch in my NuxtApp that get the routes from my Nitro app and not the internal Nuxt api routes ? Currently I create a hook "types:extend" in my Nitro app to export the route with the following code:

  hooks: {
    'types:extend'(types) {
      const routes = Object.entries(types.routes).filter(([path]) => path.startsWith('/api'))
      const defs = [
        'import type { Serialize, Simplify } from \'nitropack\'',
        '',
        'export interface Routes {',
        ...routes.map(([path, methods]) => {
          return [
            `  '${path}': {`,
            ...Object.entries(methods).map(([method, types]) => {
              return `    '${method}': ${types
                .map((val) =>
                  val.replace('../../server', resolve(__dirname, './server'))
                )
                .join(' | ')}`
            }),
            '  }',
          ].join('\n')
        }),
        '}',
      ].join('\n')

      writeFileSync('./types/routes.d.ts', defs)
    },
  }

This works well to autocomplete the routes in my useCustomFetch but it doesn't type the returned data object.

Thanks for your help :)
