TODO

• [x] tree by folder dependencies
• [x] tree by file dependencies
• [x] ignore third-party dependencies
• [x] alias handling
• [x] ignore types/interface/enum/as const dependencies from file tree
• [x] ignore types/interface/enum/as const dependencies from folder tree
• [x] ignore object which used only in types for folder tree
• [x] handle ExportDeclaration with moduleSpecifier
• [x] exclude barrel files from file tree
• [x] exclude barrel files from folder tree
• [x] guarantee id uniqueness of file tree
• [x] guarantee id uniqueness of folder tree
• [x] pass meta info about files to file tree
• [ ] pass meta info about files to folder tree
• [x] arg parser for file tree
• [x] include used export by parent
• [x] check named imports from same file on different lines for file tree
• [ ] check named imports from same file on different lines for folder tree
• [x] handle default import for file tree
• [x] handle default import for folder tree
• [x] build package
• [x] use tsconfig related to passed file path to allow running not from project root directory
• [x] publish to npm
• [x] handle files outside of folder tree
• [x] return flat list to simplify processing
• [ ] create separate method with flat structure and use getReferencingSourceFiles, include types, barrel files, styles
• [ ] check barrel files handling for default import
• [ ] circular dependencies handling?
• [ ] how to get file deps with skipAddingFilesFromTsConfig: false, skipFileDependencyResolution: false,

Tech Debt

• [x] try https://github.com/thepassle/module-graph
• [x] reuse code between file and folder tree builder
• [x] cache file tree builder? (don't need since id need to be unique for each node)
• [x] improve performance
• [x] use getReferencingSourceFiles instead own resolution implementation? in such case I will not able to ignore types/interface/enum/as const and barrel files
• [ ] fix eslint
• [ ] add test for folder tree id uniqueness
• [ ] upgrade find-up to latest version with ESM
• [ ] try find-up-simple (ESM)
