LWC Decorators | LWC Salesforce Tutorial | Basic to Advanced

Hello Trailblazers, In this video we're going to learn about decorators in LWC. We're going to see when we need to use the @track and @api decorators and how are they useful.
There are mainly 3 decorators:- @track, @api and @wire. We're only discussing about @track and @api decorator here. We'll discuss about the @wire decorator in the future tutorial when we'll be dealing with apex.

Hey, this is superb amazing tutorial on decorators. I am at very basic level in lwc and need to clarify few basic things. Coding perspective I understood what is data member and property but could you please explain that in detail. (Especially when this is question in interview )
Also can you please cover wire adaptor as well?

[@sfdcstop]

Hi Amruta, can you share the interview question? Then maybe I can identify what I should add on. Noted your suggestion for wire, will try to create a video on that 🔜

[@amrutamhasalkar3619]

@@sfdcstop I mean if the question is like what are properties, data member in lwc ?

[@ChaitanyaHota]

[@anithab1319]

sappose if we update one property in object (this object did't mark as track)and another property in function what will happen ? is that object property will update or not?

[@sfdcstop]

Hi Anitha, if you're updating an object property, you should mark it with @track to track the changes.

[@tradyrumy]

What about @wire? and kindly keep making videos as its helpful.

[@sfdcstop]

I thought about covering it in the next video but just realised I never created the further video for this series. I'll try to create one soon.

[@kumarvenkat739]

Thank u so much

[@annaramos3799]

Thank you, It is clear and useful
Just my mind is a kind of confusing if you compare this with aura cmp where you dont need to specify decorators :v
But now in these days lwc is everywhere :D

[@sfdcstop]

Hi Anna, I agree and I am sure you'll find lwc more easy as compared to aura once you create some components using it. We don't have decorators in aura but we do have aura attributes right? :P

[@annaramos3799]

@@sfdcstop Yeah, actually I think in attributes when you explained @api decorator

[@kallurma]

Thanks you for sharing your knowledge. Please help on this
I have scenario like
Quote(Parent)associated object Quote1(child) . I had overriden child(Quote1) "new" Button in aura(inside calling LWC) . When I'll create record in Quote1 object I want to display parent object details(Readonly), because I had create formula fields in Quote1 along with I need to give input other fields how to achieve this scenario.

[@sfdcstop]

Hi, If you're calling your custom component on the parent components detail page, then you should get the parent record id in the recordId attribute of aura

[@suryachaudharyverma907]

Thanks

[@AbhishekKumar-te8fj]

To the point it was

[@sfdcstop]

Thank you Abhishek! Keep Learning!!

[@priyankasuryawanshi9132]

Where is @wire decorator?

[@sfdcstop]

I thought about covering it in the next video but just realised I never created the further video for this series. I'll try to create one soon.
