Installing node modules globally
Pnpm is an alternative to npm that stores packages in a global folder (` /.pnpm-store` on the same drive) and (sym)links them from `node_modules`, thus saving install time and space requirement. Works on *nixes (using symlinks) and windows (using junctions) too. This generates `pnpm-lock.yaml`, which is not committed to repository now. Add it to `.git/info/exclude`.

Npm scripts can be executed as usual (`npm run ...`) or using pnpm for concise and more readable error messages (`pnpm run ...`). Scripts in `package.json` still use `npm` to run subscripts, that does not change.
