I created .env file and set ENV variable, which was accesbile with process.env
See https://stackoverflow.com/a/48619640/302177 for example of usage.
Above list is available for your project by running npm run env (credit: RobC on stackoverflow).
Can I use this with env-cmd?
@moos I am able to log the version and name of the package. The dependencies are not being exposed. I tried npm_package_dependencies_react and npm_package_dependencies_react_dom
@mbrevda I am trying to fetch the version of a particular package in my component. For testing purposes, I tried these npm_package_dependencies_react and npm_package_dependencies_react_dom, the console log printed nothing.
How about scoped packages? e.g. @scope/some-package
npm pkg get dependencies.react
