lockmaker is an NPM package designed to facilitate the offline installation of NPM packages. Its focus is providing a standard npm install-compatible process without requiring additional tooling or steps, and which doesn't require a separate compilation step to produce an offline-compatible version of a package.
The primary use case is mapping a project lacking a premade node_modules directory into an unmodified node.js container without network access and expecting npm install --production to get it into a usable state.
