13 extensions are included in analyses: tsx, ts, svg, snap, js, json, txt, md, gitignore, sh, html, yaml, prettierignore
5 criteria are used to exclude files from analysis:

exclude files with path like ".*/bin/.*" (Binaries for distribution) (1 file).

exclude files with path like ".*/git[-]history[.]txt" (Git history) (1 file).
exclude files with path like ".*/git[-][a-zA-Z0-9_]+[.]txt" (Git data exports for sokrates analyses) (0 files).
exclude files with path like ".*\.d\.ts" (Typescript definition files) (2 files).

Overview of Analyzed Files

Basic stats on analyzed files

Intro

For analysis purposes we separate files in scope into several categories: main, test, generated, deployment and build, and other.

The main category contains all manually created source code files that are being used in the production.
Files in the main category are used as input for other analyses: logical decomposition, concerns, duplication, file size, unit size, and conditional complexity.
Test source code files are used only for testing of the product. These files are normally not deployed to production.
Build and deployment source code files are used to configure or support build and deployment process.
Generated source code files are automatically generated files that have not been manually changed after generation.
While a source code folder may contain a number of files, we are primarily interested in the source code files that are being written and maintained by developers.
Files containing binaries, documentation, or third-party libraries, for instance, are excluded from analysis. The exception are third-party libraries that have been changed by developers.

The following criteria are used to filter files:

files with paths like ".*".

117 files match defined criteria (10,737 LOC, 100.0% vs. main code):

67 *.tsx files (6,728 LOC)
47 *.ts files (3,739 LOC)
2 *.js files (245 LOC)
1 *.html files (25 LOC)

" *.tsx" is biggest, containing 62.66% of LOC.
" *.html" is smallest, containing 0.23% of LOC.

Test Code

Used only for testing of the product. Normally not deployed in a production environment.
