Repro steps.

Fresh install using ng new, no added packages. Rearranged my directory structure so that my app is a subdirectory of a web directory. Reconfigured tsconfig.json in the root so that it uses an @app prefix for importing from the ./web/app/src folder. Modify main.ts to import from '@app/app.module' instead of './src/app.module'.

Sample repo demonstrates the issue; the README contains commands run (both non-AOT and AOT) and the two different (but related) error messages:

Desired functionality.

I am trying to structure my application so that I can use the @-style references when importing local code. It works well for non-modules, but when I go to import any module defined by the @NgModule annotation, I get the above errors. Ideally, I would expect Angular's build process to be able to compile my code regardless of how I reference imports (assuming it's set up correctly).

e.g.

// Goal
import { MyModule } from '@app/mymodule';

// vs. 
import { MyModule } from '../../src/modules/mymodule';

Mention any other details that might be useful.

The .angular-cli.json, tsconfig.json, and tsconfig.app.json are copied directly from the project where I discovered this problem.

Update: https://github.com/dohpaz42/aot-static-module/pull/1

I would like to convert this into a feature request that the error messages be updated to at least show the (resolved/real) path(s) used to look for the imports, so that if in the future this happens because a misconfiguration, it would be quicker to realize the problem (using ng build --verbose in this case does nothing).

[dherges]

Here is another repro:

.angular-cli.json: https://github.com/dherges/nx-sandbox/blob/master/.angular-cli.json#L9

tsconfig.app.json: https://github.com/dherges/nx-sandbox/blob/master/tsconfig.app.json#L8-L10

It chokes when the compilerOptions.paths target is located as a parent of the app.root (not a sub folder in apps/u-app/src in above example)

$ ng build
ERROR in ./apps/u-app/src/app/app.module.ts

[dherges]

Workarounds are:

1. copy folders to a sub-folder of app.root, e.g. for import ... from '@my/lib'
   • copy the folder to ./apps/*/src/@my/lib
2. symlink (or copy) the folders to node_modules, e.g. for import ... from '@my/lib'
   • symlink from node_modules/@my/lib to the target folder ./dist/libs/my-lib
   • or copy ./dist/libs/my-lib to node_modules/@my/lib

[jasonaden]

Confirmed this is an issue. Prevents people from developing libraries in the same project as their app if they want to use the built version of their library to build their app against.

Any update on this bug? Trying to use path within Nx and having the same issue

[Splaktar]

@hansl @filipesilva It would be really nice to at least get some labels on this issue. Perhaps it was resolved in the v6 updates?

[Splaktar]

Based on some of my tests and https://github.com/dherges/ng-packaged, this appears to be fixed in v6.

[gameboyzone]

@jasonaden - Can we test this issue and mark this issue as 'Closed' if @Splaktar is correct?

Thanks!

[jasonaden]

@filipesilva @hansl Can this be closed now?

[filipesilva]

I think so, yes. Our lib generation and consumption journey makes the library in the same project, and we test that it works.
