If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

nodemon-web copies the source of the popular `nodemon` package verbatim and reuses Remy Sharp's author metadata and the https://github.com/remy/nodemon.git repository URL, while publishing under a lookalike name from an unrelated account. package.json declares a runtime dependency on `type-swap@^3.1.3` that is not required or imported anywhere in the package's own code; the real `nodemon` has no such dependency. Installing nodemon-web therefore silently resolves and installs `type-swap` into the consumer's node_modules under cover of a familiar name and impersonated maintainer identity, adding third-party code to the installer's dependency tree that the package itself never uses.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
