Angular 4 Tutorial - CRUD Operations (get/put/post/delete) #3

Показать описание

Angular Crud operations let us get, update, post and delete any kind data. I will be using http requests to perform all these crud operations. For json data, I will be using json-server as my fake localhost api.

Gud explanation and easy to understand ...
but I have a doubt..
In our tutorial we have products with I'd's:1, 2, 4, 5, we dnt have product with I'd:3 rit, but here I want to show the product with I'd:3 .I mean it should show like 1, 2, 3, 4(order).when we deleted the I'd:3 product then immediately the product I'd:4 should updated to I'd:3 and I'd:5 should updated to I'd:4 automatically...so what should we write for this operation.

What is the purpose of promise() and then() ? I was able to achieve the same functionality without using them.

Hi Awais, can you help me or rather direct me to make my own AutoCAD session on YouTube. Just for fun. And to earn pocket money.
