I've explored numerous Angular tutorials, but this one stands out as truly exceptional. The clarity of instruction and depth of content make it a superior learning resource, providing valuable insights and enhancing my understanding of Angular development.

This was great. I built my copy by using a List component and an Add component, and having Add do an Emit, List then executes a Refresh by getting called through ViewChild. No need for refresh buttons. Best wishes!

just a neat and clean explanation.. i found it wonderful.. thank you sir for the wonderful explanation

Question: In 'onProductCreate()' , i used 'onProductFetch()' method also in method definition, so that when i create a object, it will automatically gets displayed. when compiled, its not working. But when i used a setTimeout() method for 1000ms outside 'onProductFetch()'. its working perfectly. Why it's happening?

You are the best)

Hello sir, Is there any other way to view data in html instead of transforming/observable operators ? can we do that using *ngFor directive or forEach method ?

thank you sir

thank you for the great educational material and amazing presentation. a quick question: is there any reason for using http instead of fetch api offered by the browser?

We can surely use fetch() api from angular. But its better to use angular's built-in http to handle http request and responses. This stackoverflow query might clear your doubt: stackoverflow.com/questions/53660262/angular-http-vs-fetch-api

my API return a simple text, in angular, how can i take the result that comes in json and convert to text?

I still receive the error after I change strict to false. Great videos though keep it up!

Instead of for..in method ; use this on your own risk (especially incase of nested object 😬) : for (const [key, value] of Object.entries(res)) { products.push({ ...value, id: key }); }; // no need to use hasOwnProperty() method, if we use entries() method

good morning sir i have tried to add product but i get an error while add new product

Great explanation, but what happened with json data that contains more than one object, i mean like a nested table? thanks for share your knowledge. btw i'm knew with angular, and sorry for my english xd

Thank you 😊. To access nested data, you can simply use dot notation. For example, let's say we have following json object: { Name:. "John", Address: { City: "London", Country: "UK" } } Now, if you want to access city field of address, which is a nested JSON object, you can access it like doc.address.city where doc is your variable storing the JSON object.

sir , why you didnt use services for http methods which could be more suitable to understand

hello sir, if(res.hasOwnProperty(key)){ products.push({...res[key], id:key}); } is the problem, your download source there is no content, it is empty project setup only, please update the full code and give us

i think use Object.entries() method instead of for..in loop. I am not sure though if it leads to some error😬 ; especially in case of nested object (sorry , i am noob in coding)

Sir, Thx for your great course. I got cors error by the get request. I tried to set the header without success and the Firebase Realtime Database parameter setting failed too. Please help.

Sorry, I entered the url incorrectly. What confused me was that I got a CORS error. It works now. THX.

res.hasOwnProperty(key) is useless when it put inside for(const key in res) {}. It will always be true.
