What is a REST API?

Is no one else going to say it? This video is in Dark Mode, and that's why we love it

It’s the squeaky marker for me

For me it's the fact that he's writing in mirror so we can see it correctly that through me away and took most of my focus the whole time 😅

[@AnOn-v6q]

The thing no one mentions is how he looks like Mr Beast

[@RobinShrestha1]

I'm not sure if I'm more impressed with the explanation or the fact that he wrote all this stuff backwards to our viewpoint

[@mustaphazero4929]

you can do that just by converting right with left (like what selfie does when you take a picture)

[@tannerbarcelos6880]

One of the best representations and explanations of this architectural pattern. REST really is straight forward if you can simply think about how the data should come and go in your app!

I'm a former techie who left the industry for a while, and came back as a leader of a large group of techies, so I'm playing a little bit of catch-up with videos like these, so I know what my teams are doing and can provide guidance or prioritisation.

awesome explanation! at first, I thought you were writing left handed and backwards, but it makes more sense that you were writing right handed and forwards, and then flipped the vid in post-production. I love this format! Keep it up!

[@SuganthanHarmless]

I was wondering about this too!

[@larissabranovacki8164]

came to the comments to see if anybody else had wondered about the writing! lol

[@sharpazn]

i made my first web app with REST weeks ago without knowing 100% of the concept. I wish i saw this video before! All i knew is that i needed to change my dependencies, make my link, make the client-server architecture and communicate with my DB with SQL commands. Great stuff!

[@heathergray4880]

Ok. I have watched many IBM videos trying to explain concepts but this is by far one of the easiest to understand.

Really great production. At first, the dramatic lighting was jarring, but later when the board filled up, the shadows helped separate the talent from the text we were looking at it. Bravo to the presenter, too

Was literally thinking they should have put a high pass filter on this. You can too just not listening on a mobile device.

eh, I'd disagree. I like the low-fi, intimate atmosphere with all the details that come with analog/ tangible tools. The more we can circle back to old-school teaching with modern accessibility, the better. Not everything in life needs digitally polished.

@@joshualevanPeople nowadays are too critical of everything online; if you were in the room with that guy after he gives you a lesson, would anyone bother him about his marker noise?

Beautiful explanation even a non-technical person can understand. One feedback, the marker sound was making me crazy though

[@sylvainswift3234]

Very nice video, congratulations. In order to improve it as far as it may be improved, I'd suggest a few things things : 1. 2:13 - Explain a bit more "stateless" (what it means exactly). It's not very important, but an example would illustrate well the idea ; 2. You give reasons why this way of exchanging data is interesting: I guess it would be great to give a few other ways to do the same thing, then we'd understand that REST API are actually simpler ; 3. I'd explain a bit more who and how technically the "ice cream managers" use POST request to inform of another brand new flavor. How do they do that (from an app, a web app with a form, and so on) ; 4. It would be nice too to say that any kind of app can "talk" with the REST API, not depending on the programming language. Python, C++, PHP, JS, and so on can - as soon as it has ways to make HTTP requests and handle JSON (or XML) - exchange data with the remote server-side REST API. Make no mistake, only my two cents, this video is great and I highly recommend it, but I just give you tips to improve it as I think they're quite important for a newbie. Thanks a lot!

A round of applauds for managing to write backward the entire video :)

[@robertbrautigam6720]

This is RPC over HTTP at most. Any presentation that does not include the words MediaType or Hypermedia can not be about REST. I get that the industry in general basically rejected hypermedia, but it is still an integral part of many of the advantages claimed. Also, it is not simple at all, you're just doing the simple parts and ignoring the hard ones, like caching (mentioned, but then forgotten), discovery or resources, designing the flow of the client _from the server_, etc.. That added knowledge is what makes REST so powerful, not the making some random HTTP requests with some json content. The linked "Handbook" and "REST APIs" documents are also talking mostly about the RPC-style. With the only mention of links in "paging". Don't underestimate the power of links and forms! Come on IBM, you could actually lead here, and show how it's done properly! Leave the OpenAPI/Swagger train and do it right!

Um, what is thie black magic vodoo he is doing with his whiteboarding?! I hear the marker but there is more to this. I love it.

[@michaeldebellis4202]

I thought this could have been better. First, don’t explain the benefits until you say what it is. Second, and most importantly show examples! I had heard and read about REST for a while without really understanding it. Then I saw a library of URLs with parameters and instantly I got it. I realized I had been using REST every day without realizing it. I’m sure most people reading this will think that’s totally obvious but for people who don’t know, it isn’t obvious and seeing examples always helps me make sense of new concepts.

[@odd4231]

[@mehmetdemir-lf2vm]

endpoint, method and parameters cannot always be differentiated. rest is only a solution for using a very small set of crud operations on databases. rest api just: 1. enables browsers to use http protocol to access databases 2. enables connection pooling at the application server and removes necessity to connect to a database for every function call 3. constrain the client to use only a couple of functions rather than enabling them to use full range of commands that can be used when directly connected to a database. i think a more generalized solution is required to solve wide range of operations. what i suggest is to use stored functions defined in database systems that use json as input and output. a thin and fast application server should do only connection pooling, firewall and logging functions. a server should be used to generate authentication keys and these keys should be checked by functions on the database server for authorization. with this simple design there will be almost nothing that cannot be achieved and there will never need to add extra servers to do things that cannot be done with this architecture.

[@levon9]

Really liked how CRUD ops were related to the HTTP ops (GET, POST, etc)... thank you for sharing.
