[x] Regression

Minimal Repo:

This has caused a regression for how we use ngc over on angular/universal see: angular/universal#805 (partially out fault since we don't have testing)

When you have nested submodules that have their own tsconfig's and you run ngc it will output node_modules(just metadata) along with the full directory path, rather than just the sub module


tsc: /dist/module-name/index.js

Could work around it in angular/universal by setting "skipTemplateCodegen": true in "angularCompilerOptions" in tsconfig.json. But this is a regression in ngc that should be fixed.

fix(build): fix dist/ output structure and packaging
Casued by regression in ngc - angular/angular#19339.

Worked around by adding "skipTemplateCodegen": "true" (but that is anyway needed).

This is a side-effect of our now ignoring "genDir".

We should consider paying attention to "genDir" to avoid breaking builds that used "genDir" instead of "skipTemplateCodegen" to work around this issue.


The reason the location moves is because TypeScript infers the base directory from the common root directory of all files included in the project. Without "genDir" the factory files are produced in the corresponding directory in node_modules. This makes the inferred baseDir to be the project root directory instead of the directory containing the tsconfig.json file.

Supplying "genDir" in 4.0 caused the files to be generated as a subdirectory of the directory containing the tsconfig.json file avoiding this issue.

Supplying "skipTemplateCodegen" in both 4.0 and 5.0 avoids this issue because the factory files are not generated and are not added to the project avoiding this issue.

Closing as works as intended, but we need to document this different behavior.
