Thank you very much, bro. Really hats off to your hard work, commitment and patience. Definitely one day your channel will become a great success and learning path for so many enthusiasts like me. Though I'm working as a junior MEAN stack developer, I'm learning a lot about these technologies in depth like architecture and best practices.

Thank you so much buddy

A small suggestion, I think It is better to implement a centralized error handling mechanism in node js for a solid architecture design. Please try this may be in later projects or videos.

[@ARCTutorials]

hi varaprasad. Yes I will refactor and implement centralized errors in next few tutorials.

[@Jerryb821]

[@JUNGELMAN2012]

This episode and previous are confusing prior episodes that covered the same topic of connecting to DB with Mongoose. You need to share the end code so we can check.

[@crazyfellow1200]

For those who are facing problem with save() use this code newStudent.save(). then(()=>{ res.send(newStudent); }) .catch(err=>{ console.log(err); })

[@ARCTutorials]
