sir i am beginner and i learnt lot of things from your video ....thanxxx sir

[erised-_-]

for those of you who are having problems with map use this :
return this._http.get(this.baseUrl + '/users', Response) => response.json()));
you need to use pipe before map with this import : import { map } from 'rxjs/operators';
for those of you who have a problem with observable use this :
import { Observable } from 'rxjs';
as for those who are still having an error with catch, i just deleted it

For those who are in trouble, the libraries he is using are deprecated, you will have to look for replacement libraries on Google.

Thanks for the tuto, but is it a mistake or you don't want to provide the angular front-end in the github ? :-)

Just a question regarding your angular version used. I tried this using angular cli 6 but had issues regarding the .map function. What was the version you used for this project?

[toddsmith]

I am getting this error - [ts] Property 'map' does not exist on type 'Observable<Response>'.

return this._http.get(this.baseUrl+'/users', this.options).map((response:Response)=>response.json())
.catch(this.errorHandler);

[carlosdelatorre]

If anyone is getting the Map error while doing this it is because you're on a newer version of Angular/rxjs. I did the following and was able to resolve the errors. Someone please correct me if I'm wrong.

import {map, catchError} from 'rxjs/operators';

return this._http.get(this.baseUrl+'/users', this.options).pipe(map((response:Response)=>response.json())).pipe(


I added ".pipe" before map and before the catch error.

Hi Samba. thanks a lot for the tutorial. however, i got this problem

basically, i only can fetch the dummy data from backend, but can't do the create, update, delete function as property.
the origin stuff you set up on backend should not be any problem. Is it the problem that I am using angular 6 I need to use httpclientmodule. I am not sure the problem is this.

hai first of all thanks!, i have a small doubt on the createUser() method. Actualy it is a post request is any use with .map() function in it.please give a proper answer. thanks
