package-lock.json - npm dependency lock file

package-lock.json is automatically generated by npm to lock dependency versions. It records the exact version of every installed package and its dependencies, ensuring reproducible builds.
The file should be committed to version control to ensure consistent installs across environments.

Don't edit manually. Commit to git. Use npm ci for CI builds. Conflicts common in merges.

package-lock.json was introduced in npm 5 (2017) to address reproducibility issues, replacing npm-shrinkwrap.json for most use cases.
