NxTreeChildren

A repository for reproducing the tree.children filtering issue on Windows machines

Currently, there is a filter in the tree.children method to exclude deleted files from the list.

https://github.com/nrwl/nx/blob/881067bbd24431e025ecf3ba9e5849a1c824d6b5/packages/nx/src/generators/tree.ts#L284-L287

However, due to the Windows path separator, this filter fails to work properly on Windows machines. When dirPath is apps/test and q is file-a.json, the join(this.rp(dirPath), q) function returns 'apps\test\file-a.json', which is not recognized by recordedChanges. As a result, the filter always returns true, causing deleted files to remain in the list.

How to test

1. Open the workspace above on a Windows machine
2. Run npm i
3. Go to the src/app/app.component.spec.ts file where there is a test to add a file with a nested path to the tree then remove it and expect the list from tree.children to be empty
4. Run the test in that file
5. You should see the test fails on a Windows machine which indicates that the tree.children doesn't work. As a result, the children list is not empty.
