Amazing... !! You make things so simple.. !! A great learning experience..! I never understood REST so well before.. !! i was so much involved with your tutorials that i finished all 8 classes till now in ONE single day ..!! waiting for more..!! keep up the Good work Koushik.. !! Kudos to you.. ! Appreciate the hard work involved by you and your team..!!
Pavan D C Thanks. I wish I could convey the thanks to my team, but considering that it's just me and nobody else, I guess I'll keep it all to myself! :)
Java Brains Why you never advertise you paid courses like your "Building Web Applications with Spring MVC"? Do you have other paid courses out there? I am willing to grab those
You are simply SIMPLE(Super Inspired Master by Professional,Learners and Experts). Provide oxygen to breathe and give ice cream with honey to relax - this is what I feel from your lecture sequence and flow. It is not justified to appreciate a master but please accept my humble gratitude, all of your materials are great use to me.
When i Started to learn about REST i was totally blank But U my friend !!!! U are rocking, U make REST so simple to understand I just finished all 8 tutorials in single sitting... Thank you and waiting for next tutorial series and making "Messenger" APP.
I remember first time I saw this video long time ago, at that time I did not understood, but I really appreciate your effort to teach about WebServices, today I can understand HATEOAS terminology thanks to u JavaBrains-Koushik. Thank ü
Simple and profound. Your tutorials helps understand many concepts, aspects, that we use on a daily basis and teaches true purpose of it. This is a great tutorial for anyone who wants to quickly get started on HTTP funda along with REST.
This is the best tutorial for Java Programmers and those who are new to Java. Everything is perfect in this tutorial, right from concept, examples including speaker tone and word frequency. I learnt really well and would not been easy without this tutorial. I am holding my breath to learn coding Restful API's watching your tutorial. Please post it soon.
I have to learn in my programming course a lot of RESTful APIs and all the things that come with it. This video was helping me so much!! This is the best video I have seen so far about it! Thank you!
Spring Data Rest provides HATEOAS capabilities in the most amazing and simplest way I've ever seen and to complete the job, it also provides a mechanism which provides all the semantic of the requested resource called ALPS. I've found your explanation of HATEOAS simply good as the programming code I love to see.
Hi Koushik...let me first applaud at the way you have presented these tutorials. Its simply amazing. I will be waiting for the continued content on this. Keep up the great work!!!
Thanks Koushik for making things so simple but yet bang on. This is the first time ever I have found a place where I can say... Yes I have learned something today... great and thanks for this wonderful sharing of your expertise knowledge.
No words...Simply simple and superb ! Looking forward to the entire series soon to get a good and solid hands-on with RESTFul Web Services through your teaching.
I tried to learn REST by reading different tutorials. Your videos made things very simple and systematic. Now I have better understanding of it. Thanks a lot Koushik :)
This was a fantastic tutorial. Made things SO simple, whereas so many videos and articles on this that I've read so far seem to make appear far more complex. You're a great teacher. I've subscribed!
if someone ask me who is god of java means,i would sure say your name.what a simple and crystal clear explanation from now i can say proudly REST is Peace
Very beautifully explained? Very much excited to Learn more on this topic. I am disappointed you stopped at this chapter. Was eager to go through all the classes.
Another awesome tutorial! I want to take this opportunity to thank you for all the amazingly easy to understand tutorials you have done on various topics. So thank you very much!! Keep up the good work!
Thanks for the tutorial. Beautifully explained -- I'm looking for ways to improve an existing API and was curious about how we could apply HATEOAS concepts. This made it very easy to understand. Well done.
This is a amazing tutorial. But was disappointed to see HATEOAS is the last tutorial in this section. Desperately waiting for further tutorials on REST. Please....
Thank you Kaushik!! Your videos are really amazing and very clear. Keep posting. Waiting for next set of tutorials on hands on development of restful webservices.
Awesome .....Tutorial.....helped me a lot.....Highly appreciable !!!!!Have complete all the classes in 1 go........wow..........Thank you!! waiting for more classes.......Thank you :)
Hello sir! I wanted to thank you. Yet, the word "THANK YOU" seems not enough to the efforts you are providing. I hope you got my appreciations. SO PROFESSIONAL.
There are many good comments already. I just want to say i agree with them all. Your technique/skills are unmatched. How do you do this magic? .... you are some kind of artist or what!!!!! . And finally.. we are lucky to come across your tutorials. Well done. How can i donate?
Hi Kaushik, this series was mind blowing. I am probably repeating myself but your videos really helped me see REST from a whole different way. The only request I have is, it's been 2 months and we're desperately waiting for your next posts in this series and we want to know when will they come? :) I am so addicted to them that I am okay to pay if you're planning to upload them on any subscription based sites. Please let us know in any case
Thanks Koushik for explaining basics of REST with very good details. Please let me know when can i get next set of tutorials to start with building REST apps.
Providing links back to the client in the rest response when all of those links can be inferred can come into conflict with scalability concerns, esp with respect to bandwidth issues for busy sites - I don't disagree with the approach per se, the objective is good, but the final example has at least half the data as links to other material that can be inferred. This is a good example of where a good approach from a clients perspective might not be such a good approach from the servers perspective - granted this needs to be resolved on a case by case basis, or at least site by site.
Most of the REST APIs will have a workaround for it when you 'GET' a resource in first place. As an example, when we invoke Oracle Fusion REST APIs we can pass a query parameter onlyData=true and that removes the extra links.There are ways you can do it for POST/PATCH as well, just that the response will be 204 and not 201.
but client has to know the "rel" attributes which need to be accessed if not the hardcoded uri. In case of humans hyperlinking is ok because humans can read and infer the function of the hyper link as they are browsing.. but how does a computer program infer from the "rel" attribute what the function of that uri might be without knowing beforehand a mapping between "rel" and the function. this takes us back to documentation needed for the api but this time about the rel attributes.
The link given in the description section of the videos does not have content in it. It displays "Not FOUND: 404" when it's clicked. Please do the necessary changes.
Very nice video! I never actually have though about what "rel" means in case of linking style sheets for example. But it makes sense sure. What I don't really understand is how using links property in response is any better than using multiple href, other than being just tidier of course. If let's say rel: comments is not standard doesn't that mean that client still has to know what rel value it's looking for in order to get link to comments. I still like this links property / array but don't understand how it tackles the issue where client has to know property name. Client still has to know some name, whether it's being property or rel value. I know this is old video and I'm not excepting an answer from anyone, just thinking out loud :)
Very good talk! I've built Restful APIs for a while now. Just a question, by providing all these links to the client of the API, won't this make the responses much larger and slow down response time? Also, normally I'm against unnecessary documentation however I do think that it's good to list root end-points for APIs and then from each root show what http methods are available for that end-point. Normally I'm used to writing in the documentation that (using your example) if you wanted other info associated to /messages you could do /{Id}/likes .... etc.
8 years later and still the best series on REST , very well explained.
This is by far the best tutorial on REST, not only for JAX-RS, but REST in general.

Man, so good..you are a [0] in my array of teachers
Excellent!! Thanks a lot for sharing your knowledge.

Why you are so damn good in explaining things ???
Beautifully explained. Subbed!
very good illustration of the concept
You are a very good teacher
great lectures koushik .. thanks man
Thank you so much for this tutorial.concepts are very well understood
Flawless explanation.
The link given in the description section of the videos does not have content in it.
It displays "Not FOUND: 404" when it's clicked.
Please do the necessary changes.
Nicely done!

Json structure at 6:21 is incorrect!
Very good talk!
I've built Restful APIs for a while now.

Also, normally I'm against unnecessary documentation however I do think that it's good to list root end-points for APIs and then from each root show what http methods are available for that end-point.

God level teaching
as always you are excellent ....pls upload the next videos
excellent videos and explanation
Hi Koushik,
Your tutorials are simple and good, let me know your future tutorials topics.
Thanks
