These changes are good and make the RxJs more useful. To be honest, I hate breaking changes, but RxJs needed these breaking changes. Importing and finding the operators and observable methods was a pain in the a**. I remember that I spent more than an hour because importing Observable from 'rxjs/observable' but not from 'rxjs/Observable/'. I hope they'll make one and a good breaking change. Thank you for the good explanation :)
This really helped! Since I started on Angular 6, It was a terrible blockage for me, reason being Subscribing to an Observable syntax changed. Thanks a ton Max! :)
Thanks a lot Pavel. Alternatively you can also dive into the article in case you prefer the written form: academind.com/learn/javascript/rxjs-6-what-changed/
Nice update about RxJS. A tutorial about the new state management library "ngxs" and how to implement CRUD operations with the http client there would be great!
Hello,the video was very much informative,i am facing few related issues,"Property 'wheelDelta' does not exist on type 'WheelEvent'" this occurs on upgrading to angular 7 for mouseWheelEvent. Any solution for this?
15 minutes reading github.com/ReactiveX/rxjs/issues/3654 Takeaway: still rather confused. 6 minutes watching this (at high speed) Takeaway: my project now compiles and my problems are gone. YOU ARE THE MAN!
It gets even better. I'm on a tear, learning Observables, and was scouring internet for how to map one object to another. Well, once I figured it out, it was again your video. Unintentionally, you gave me an answer to questions your video didn't even set out to explain! If the below code looks a wee bit familiar, it's because I scraped the tricks from your code on screen... this.tenantService.getTenants() .pipe( map( data => { return data.map( el => ({ label: el.tenantName, value: el.tenantName})); } ) ).subscribe(tenants => { this.tenants = tenants; });
Thank YOU for your comment, happy to read that you like the video!

i had hard time using material in angular 6, too much work, but material app looks cool, what do u suggest shall i use bootstrap or material, i see bootstrap has more features, am i right
It really comes down to which style you want - also keep in mind that Angular Material is a component library, not just styles. It can therefore provide a lot of components you don't have to create on your own. Though there also is an Angular-implementation of Bootstrap, so I guess we're back to the "Which style do you prefer?" part ;)
Now operators are pure functions and could clash with other libraries... Why do they do that? Also now you don't chain methods (which was beautiful) but call a pipe() method and pass operators as arguments (ugly in my opinion). Maybe the only reason is for simplicity for users to create their own operators to pass within pipe(). That could lead to the bad practice of declaring operators everywhere in the codebase...
Fredo Corleone I agree. This is setting a bad precedence. If other developers and libraries were to follow this pattern it would create a complete mess of incompatible libraries. “of” will almost certainly be a reserved keyword in the future so i wouldn’t be surprised if they have to make breaking changes again in the future because of this short-sighted decision.
You can just rename the imports in that case: import {map as rxMap} from ".." > Why do they do that? Good explanation for the rationale for the changes: ua-cam.com/video/JCXZhe6KsxQ/v-deo.html
The reason is that now that these operator functions are separate exports instead of bound to the Observable class, it's finally tree-shakeable, resulting in smaller bundle sizes and better flexibility. Imagine a library that would expand the basic RxJS Observable prototype by adding a functions to it. If you'd want to use another library that does the same, it could clash with your previous ones. By using separate function you can chose which to import anytime. github.com/ReactiveX/rxjs/blob/master/doc/pipeable-operators.md#why
Does anyone knows what vscode extension does that pretify on 10:18 part (when he presses return and the last parenthesis separates on the end too). Thanks in advance
Max has been the biggest single contributor to my programming career. Bought a few of his Udemy courses, and highly recommend them to everyone who is starting out.
Hi Max, i buy your course Learn Angular 6 from Scratch and I'm faced with the problem of rendering the list of subscribers by analogy of your code with recipes. this list is not rendered for some reason. I could not define it. I wrote to the technical support course, but at some point, your assistant refused to help me further, saying that many questions were being received. Please, could you help me with my case. Or rewrite your code from 24 chapters using the most recent versions of the libraries and angular 6. Thank you in advance
I'm sorry, but we can only offer support for questions closely related to the course projects. Try to compare the code in your project with the code attached to the course lecture or post such questions in forums like Stackoverflow, this should help you to solve the problem.
I didn't get why reason for rename was function name same as reserved word...What does it mean? You can call function anything and should not be a problem. See this: jsbin.com/gadibekucu/edit?js,console
Thanks Max for transitioning to latest changes in such a simple and lucid manner.
The clarity that you have over these concepts.. makes you amazing MAX :)
You're so good at teaching! I'm attending your udemy course about angular and it's super! so clear! Thanks!
Thanks for this guide. Just upgraded my pet project to Angular 6 and couldn't completely understand Rx related errors. Now everything is clarified.
Really great to read that the video was helpful for you Andriy, thank you for your comment!

Yeah, the updated import paths and the different operator usage are indeed really useful
This really helped! Since I started on Angular 6, It was a terrible blockage for me, reason being Subscribing to an Observable syntax changed. Thanks a ton Max! :)
Thank YOU for your comment Saily, so happy to read that the video helped to make things a bit clearer :)

Funny thing about youtube, I just saw an ad for someone elses udemy course before this video!
That's kind of what it is I guess. Others also have great courses, but joining our courses is hopefully also not the worst choice ;)

thank you ,very useful
Dear Max and Manu, React VR is being released these days....Will you create a crash/introductory course on React VR? It's gonna be very cool topic!!!
We might but I can't promise it. Thanks for the suggestion though!
that api is really limited, it has like 3 or 4 components....I doubt you can make a course out of that yet, anyway thanks for the video, it worked!!
Awesome tutorial, thanks
Hello Max, does the order matter inside the pipe()?

Thank YOU for your comment!
sos un idolo me solucionaste un problemon :(
Thank you my lord.
Thank YOU for your comment :)
it is the same with ionic 3 or should i wait ?
Ionic 3 still uses RxJS 5.5 I think. Ionic 4, now in BETA does use RxJS6
Can I get the github link?
great channel ;)
Happy to read that you like it George :)
Good Explanation.. Bye..see ya
I didn't get why reason for rename was function name same as reserved word...What does it mean?
You can call function anything and should not be a problem. See this: jsbin.com/gadibekucu/edit?js,console
You're the best
Oh my, no longer spaghetti imports in rxjs?
Yeah - finally!
Seth Rogan?
Maybe ;)
Thanks bro, you're amazing
