Angular 2/5 User Registration and Login Example

angular2-registration-login-example's Issues

ng serve is not working

Versions of @angular/compiler-cli and typescript could not be determined.
The most common reason for this is a broken npm install.

Please make sure your package.json contains both @angular/compiler-cli and typescript in
devDependencies, then delete node_modules and package-lock.json (if you have one) and
run npm install again.

Alert Services

Alert service not working properly can't find the problem.

Alert Services

Hi Alert services is not working , I tried to dig out but unable to fix it.. I am new in angular2 , so please look in it.

import { Component, OnInit } from '@angular/core';
import { AlertService } from './../services/index';

@component({
moduleId: module.id,
selector: 'alert',
templateUrl: 'alert.component.html',
providers: [AlertService],
})

export class AlertComponent implements OnInit {
private message: any;

constructor(private _alertService: AlertService) {}
ngOnInit() {
    this._alertService.getMessage().subscribe(message => { 
        alert(message);  // on error this is not executing
    	this.message = message; 
    });
}

}

Migrate @angular/http to @angular/common/http

With current version of Angular (5.0.1), the @angular/http NPM package is deprecated.

Reference for migration : http://blog.ninja-squad.com/2017/07/17/http-client-module/

property success does not exist in type Response

this.authService.authenticateUser(user).subscribe(data => {
if (data.success){
this.authService.storeUserData(data.token, data.user);
this.flashMessages.show('You are now logged in',{ cssClass: 'alert-success', timeout:5000});
this.router.navigate(['/dashboard']);
} else {
this.flashMessages.show(data.msg, { cssClass: 'alert-danger', timeout:5000});
this.router.navigate(['/login']);
}

 });

i later changed it to
if (data['success']){.............
but while login it is going to dashboard even if the password or username is wrong...
