You can install the 'version-check' library from npm using

npm install -g version-check

And then call 

version-check rxjs

Hope this solves your problem.

This will show all NPM package versions if you installed with NPM.

npm list --depth=0

If you leave out the --depth then you'll get all their dependencies also.

You could do something like:

const package = require('rxjs/package.json');
const is5 = /^5\./.test(package.version);

console.log(package.version);
console.log(is5);
