Dependency Checker — EOL Dates

Runs the same checker as our npm package on a Node.js runtime that pip installs for you (nodejs-wheel-binaries) - no system Node.js needed. Your files are checked locally.

Dependency checker for package.json, composer.json and requirements.txt. On the sample package.json (Angular 19 + Express API, _fixtures/dirty.json) checked on 2026-09-28 it finds six dependencies past or near end of support: express ^4.21.2 (EOL target 2026-10-01), @angular/core ^19.2.0 (ended 2026-05-19), eslint ^8.57.0 (ended 2024-10-05), bootstrap ^4.6.2 (ended 2023-01-01), angular 1.8.3 (ended 2021-12-31), request ^2.88.2 (deprecated 2020-02-11).
