How to make an “alias” for a long path in angular-cli?

I want to draw the attention that editing only the tsconfig.json will be effective in the code completion and building via the ts compiler. the Agular-CLI, however, can't recognize the defined address to the true paths as long as you do not define them, in addition, in the tsconfig.app.json. ng serve will show build error TS2307: Cannot find module '@...

Whereas, restricting definition into the latter will make the ts IntelliSense compiler show them as unrecognized paths

In short: define the paths in both tsconfig and tsconfig.app JSON files

I found this question when tried to resolve scss. I found current approach will not work because of this issue

workaround is to add stylePreprocessorOptions to .angular-cli.json so it will resolve all styles within the directory

{
    "apps": [{
        ...
        "stylePreprocessorOptions": {
            "includePaths": [
                "./app/global-styles"
            ]
        },
        ...
    }]
}

for server-side rendering you will need to add this for both ssr and main app build - otherwise you will get NodeInvocationException: Prerendering failed because of error: Error: Cannot find module 'C:\Users\...\ClientApp\dist-server\main.bundle.js'

{
    "apps": [{
            ...
            "outDir": "dist",
            "stylePreprocessorOptions": {
                "includePaths": [
                    "./app/global-styles"
                ]
            },
            ...
        },
        {
            ...
            "name": "ssr",
            "outDir": "dist-server",
            "stylePreprocessorOptions": {
                "includePaths": [
                    "./app/global-styles"
                ]
            },
            ...
        }
    ]
}

try this in tsconfig.json:

  {
  "compileOnSave": false,
  "compilerOptions": {
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "target": "es5",
    "typeRoots": [
      "node_modules/@types"
    ],
    "lib": [
      "es2017",
      "dom"
    ],
    "paths": {
      "@services/*": ["app/services/*"] // here!
    }
  }
}
