add this

require("module-alias/register");

to the top of main.ts

Yes, add this line on the top of main.ts, but have the same error.

strange but lets see what is missing here Its a simple module which looks for the alias we have created in package json

• tsconfig points to the src path
• package json will point to the build path its can be a build dir or dist based on dist config

npm module "module-alias": "2.2.2"

This must be in your package JSON (path should point to your build output)

  "_moduleAliases": {
    "@auth": "build/api/auth",
    "@core": "build/api/core",
    "@lib": "build/api/lib",
    "@domains": "build/api/domains",
    "@proxy": "build/api/proxy"
  },

tsconfig

  {
  "extends": "@tsconfig/node14/tsconfig.json",
  "compilerOptions": {
    "module": "commonjs",
    "declaration": true,
    "removeComments": true,
    "allowSyntheticDefaultImports": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "strictPropertyInitialization": false,
    "sourceMap": true,
    "outDir": "./build",
    "baseUrl": "./src",
    "incremental": true,
    "skipLibCheck": true,
    "paths": {
      "@auth/*": ["api/auth/*"],
      "@core/*": ["api/core/*"],
      "@lib/*": ["api/lib/*"],
      "@domains/*": ["api/domains/*"],
      "@proxy/*": ["api/proxy/*"]
    }
  }
}

if this does not help will add a simple app as Demo

[bryanus1]
