RxJS and Observables with Angular 2

One note there is a error I made early in the video at 1:50. I forget to resolve the promise and the console log the value given. I correct it at 4:50 later in the video.

This is a great tutorial for people who already familiar with Angular 1 and want to learn how observables work in Angular 2. Your examples and references are really good too - Taking the help of promise to get in observables, youtube search bar for explaining in what case switchMap operator could be used and finally those stream diagrams and RxMarbles reference really made my day. Thanks for explaining us RxJS and Observables :)

that was really informative Cory, well done!

Best video about observables I've seen so far!
Great Job Cory!

[LehelVass]

Just wow. The best rxjs and Observables explanation till now. Big thanks, Cory!

This one was beautiful! The best entering point into an Angular|Rx haunted house.

Thanks Cory: great turotial ! I've already watched tons of videos on Reactive programming and RxJS. Despite that, the value of your video is great because it offers two concret examples for Angular 2 developers. Marble diagrams were clear and allowed to see what happens to the data streams.
The only thing that could be improved is the sound quality. It took me two years to get rid off my headset and go for a Rode NT-USB (I bought second hand) for recording screen casts. No configuration required, anti-pop filter included. Just a suggestion ;)

Cory. Awesome stuff. This was really easy and practical. I can see myself applying the concepts immediately. Thank you so much!

I was afraid by the beginning of the video when you explained the promise (see your comment ^^), but then, the more I was watching the video, the more I was saying "waaaaw". That's a really good video showing a good overview of RxJS. The only thing that is lacking (imo) is the setup of the project. Here, you already npm'ed the stuff you need, created your module and imported it using "systemjs", but I think it would have been awesome to quickly go through that as well, but it's a detail. Really good stuff, thanks.

best video! Thought i would take me ages to get observables!
By 15min, I have already found the solution for my problems!

Best tutorial on Observables! Thank you!

[davidjpfeiffer]

Great introduction to Observables! Looking forward to future videos.

Great video, a pleasure to watch. Also, Observables are awesome. I am quite new to the Angular framework as a whole, and the way that application is implemented is pretty much mind blowing to me. I would have achieved pretty much the same result with jQuery, Ajax, custom code, and all in all about 4 to 5 times the lines of code you wrote there :(

Great tutorial man! the best I've watched so far.... Keep posting more!

[JBuchmann]

Wow, the bit at the end where you directly bind the Observable to the HTML *ngFor loop (with no subscriber) really blew my mind! I finished a course on Udemy, and the solution there was to subscribe and put the values into an array first. This is so much better!

Great video... only complaint is it's difficult to see the code on a 10" tablet. Would be great in future if you increased the font size of the code. :)

fwiw, i learned more about Observables in these 40 mintes than i've learned from google/StackOverflow since being thrown into the TypeScript/A2 deep end about 2 months ago.

best video on ng2 and observables I've found. nice work thank u!

[silassindraribeiro]

Now I really know how to deal with "ngrx/effects" in my redux app! Thanks a lot!

[janicknorman]

You're a beast at explaining things.

[rrameshbtech]

Very good one on observables. Thanks Cory.

[thavarajan]

damm, this is awesome? one of the simplest explanation about observable, thanks buddy i am going to subscribe your channel
