Well, I have a pretty good github profile https://github.com/apsdehal but I still had a hard time finding intern this year. So I would say most of the github profile doesn't matter much, but it sure makes you look impressive. Also as far as I have experienced, if you apply in big companies, nothing matters for internship, only thing you should know is competitive programming.
Check whats your need, if you are building up much bigger apps go for a fully fledged framework, rest for small apps you can use microrouters , according to your need, each has its own unique features.
