调研方向

先从 src/runtime/plugin.ts 和 playground/app.config.ts 中的复现开始，然后检查 playground/node_modules/myPackage/dist 下生成的声明。运行 pnpm prepack 以复现 TS2742，并将失败的声明与使用 Params = string; 的变体进行比较；当模块能够在没有不可移植的推断类型错误的情况下构建时，即表示完成。

描述

bug workaround available

Im trying to pnpm prepack a nuxt3 module with a package which exports a simple object and its types file.

1 - In the playground/node_modules/myPackage/dist

index.d.ts :

type Params = string[];

declare const endpoints: {
    abc: (q: Params) => string;
};

export { Params, endpoints as default };

index.js :

// src/index.ts
var endpoints = {
  abc: (q) => "test"
};
var src_default = endpoints;
export {
  src_default as default
};

2 - In the playground/app.config.ts

import endpoints from "myPackage";

export default {
    endpoints
};

3 - In the module, src/runtime/plugin.ts :

import { defineNuxtPlugin, useAppConfig } from "#imports";

export default defineNuxtPlugin(() => {
   
  return {
    provide: {
      backend: useAppConfig().endpoints, 
    },
  };
});

Then, i run pnpm prepack and i always have this error :

ℹ Building my-module                                                                                                                                                                                                                                  12:16:16 PM
src/runtime/plugin.ts(3,1): error TS2742: The inferred type of 'default' cannot be named without a reference to '../../playground/node_modules/@aurionsarl/auberdog-pension-api/dist'. This is likely not portable. A type annotation is necessary.

}

And the error disappears if i replace the code in the playground/node_modules/myPackage/dist by this one :

type Params = string; // replace string[] to string

declare const endpoints: {
    abc: (q: Params) => string;
};

export { Params, endpoints as default };
