The best video about jwt in gin so far

[@pss_crs]

I'm not sure you have that in mind but you also have a good description of architecture and workflow

[@dhij]

Appreciate that!

[@Juswahh]

Exactly what I wanted to learm today.. thank you youre awesome my friend

[@dhij]

Glad it helped!

[@sustainedcruelty]

Thanks so much for making this. It was super useful and easy to understand!

[@dhij]

thats awesome! appreciate that!

[@min-of8cv]

Nice & clear explanation, keep up the good work. Hopefully there would be a part 2.

[@dhij]

Thank you! Yup, I will have part 2 out real soon!

[@lucamanfrin6456]

Awesome stuff! It would also be cool to see how you would deploy this app

[@dhij]

Thanks! Yup I will make some of those in the future.

*dispatch(login(email, password))* _Argument of type 'ThunkAction' is not assignable to parameter of type 'AnyAction'._ How to resolve this error? Thanks!

[@dhij]

Are you getting this error in the login screen when you try to call the dispatch() function inside the submit handler? My guess is that you did not specify the type for your login function in src/actions/userActions.tsx. Please refer to 18:12 of this video: kzbin.info/www/bejne/hmGVXqSaabOqm6c

[@yakup4861]

Great video! Can you update the github repository by any chance? The frontend is missing some files.

[@qizhang5749]

Do you have a github link of the final result?

[@unlite2896]

Please clarify how safe it is to use JWT authorization without refresh token and even more so to save the token in a cookie?

[@dhij]

This is just a demo project covering the basics so is only suitable for development purposes and unfortunately not production-ready safe.

[@andifaizal6848]

Great

[@dhij]

Thank you!

[@namtruong4071]

Good Content. Besides, Could you please speak louder. The volume is so low.

[@dhij]

My bad on that, I started using a microphone from the following video!

[@Ben-uh4wt]

Hi, enjoying the video as someone who is fairly new to Go. Could you explain why (in /utils/errors/rest_error.go) we return a reference to the RestErr in NewInternalServorError() and NewBadRequestError()? Is it to avoid having overhead due to copying the RestErr later?

[@dhij]

Hey Ben! You are right, if we pass by reference, we would only need to create the RestErr struct once and pass it around. I made a video on pointers recently and you can refer to 7:33 here: kzbin.info/www/bejne/ZmfXgKtmbdism5I Refer to 2:46 as well, where I talk about how a variable that is initialized in a function is automatically stored in the heap.
