I recently installed angular 13 and tried to install @nestjs/ng-universal with

ng add @nestjs/ng-universal

which worked for previous angular versions but I get Package successfully installed then this error:

*An unhandled exception occurred: Package subpath './schematics/utils' is not defined by 
"exports" in C:\Users\ADMIN\kiambol\node_modules@nguniversal\express-engine\package.json
See "C:\Users\ADMIN\AppData\Local\Temp\ng-1gySjP\angular-errors.log" for further 
details.*

And the full error in the angular-errors.log file is:

[error] Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './schematics/utils' is not defined by "exports" in C:\Users\ADMIN\kiambol\node_modules@nguniversal\express-engine\package.json

at Module._compile (internal/modules/cjs/loader.js:1072:14)

When I look at the angular project files, nothing has changed and the server files is not setup setup. I tried to create different angular projects just to see if my angular project was not select correctly then added ng add @nestjs/ng-universal again and still got the same result.

To test things out I tried installing @nguniversal/express-engine with the ng add command and this installed correctly with no issues and everything was setup correctly.

Did anything change in the installation process; am I doing something wrong; or is Angular 13 not yet supported?

Please help.

AFAIK i think it an error from the @nestjs/ng-universal side.

as a quick & dirty solution start by installing @nguniversal/express-engine then go to node_modules/@nguniversal/express-engine/package.json and :

  • remove : "type": "module"
  • add in exports:
    "./schematics/utils": {
      "types": "./schematics/utils/index.d.ts",
      "esm2020": "./schematics/utils/index.js",
      "es2020": "./schematics/utils/index.js",
      "es2015": "./schematics/utils/index.js",
      "node": "./schematics/utils/index.js",
      "default": "./schematics/utils/index.js"
    }

then ng add @nestjs/ng-universal should work fine and by updating the packages it should revert the changes

With Angular 13, "ng add @nestjs/ng-universal" creates error. Because it uses the latest verison of library, that is 6th version. Intstead you can use "ng add @nestjs/ng-universal@5" and it works perfectly fine.
