Add npm lockfile and packageManager info #40
Description
The repo doesn't include lockfile, which is a bad practice. See:
- https://docs.npmjs.com/cli/v10/configuring-npm/package-lock-json: "
package-lock.json... is intended to be committed into source repositories" - https://pnpm.io/git: "You should always commit the lockfile (
pnpm-lock.yaml)."
Please commit the lockfile of whatever package manager you use. Also, please consider setting "packageManager" under package.json, see https://nodejs.org/api/packages.html#packagemanager.
