Turborepo - library consuming another library - You may need an appropriate loader to handle this file type


Reproduction app: https://github.com/uriklar/turborepo-lib-dep-lib-repro

I'm using Turborepo's basic example (nextjs app + ui library)

I want to add an additional ui library and have my ui library depend on it.

// packages/ui/Button.tsx
import * as React from "react";
import { Button as AnotherButton} from "anotherui"
export const Button = () => {
  return <><button>Boop</button><AnotherButton/></>;
};

I created the anotherui library inside the packages directory and added it as a dependency of ui like so:

{
  "name": "ui",
  "version": "0.0.0",
  "main": "./index.tsx",
  "types": "./index.tsx",
  "license": "MIT",
  "dependencies": {
    "anotherui": "workspace:*"
  },
  "devDependencies": {
    "@types/react": "^17.0.37",
    "@types/react-dom": "^17.0.11",
    "tsconfig": "workspace:*",
    "config": "workspace:*",
    "typescript": "^4.5.3"
  }
}

When I try to build the web app (that consumes Button from ui) I'm getting the following error:

web:build: Failed to compile.
web:build: 
web:build: ../../packages/anotherui/Button.tsx
web:build: Module parse failed: Unexpected token (3:9)
web:build: You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders
web:build: | import * as React from "react";
web:build: | export const Button = () => {
web:build: >   return <button>Boop</button>;
web:build: | };
web:build: |

web:build: ../../packages/anotherui/index.tsx
web:build: ../../packages/ui/Button.tsx
web:build: ../../packages/ui/index.tsx
web:build: ./pages/index.tsx
web:build: 

My question is:
Is it possible to have one library depend on another library from the same monorepo?

Thanks!


Solution

  • Found the solution. It was actually related to Next.js.
    Turborepo already uses a module called "next-transpile-modules" and in my next.config.js file I already had this line:

    const withTM = require("next-transpile-modules")(["ui"]);
    
    

    So I just added "anotherui" to the array and it worked
