I am using a contact form in my application.In this i am sending the contact form details on a particular email id. All this i have to do in angular 6. I have tried this using nodemailer but not getting proper procedure to implement it. Thanks in advance

this is support.ts

import { Component, OnInit } from '@angular/core';
import { FormGroup, FormBuilder, Validators } from '@angular/forms';
import { client, response } from '../../interface'

import { ClientService } from '../../services/client.service'
import { EmailService } from '../../services/email.service'
import { Store } from '@ngrx/store'
import { AppState } from '../../app.state'


@Component({
  selector: 'app-support',
  templateUrl: './support.component.html',
  styleUrls: ['./support.component.css']
})
export class SupportComponent implements OnInit {
  angForm: FormGroup;
  osVersion: {};
  browserName: {};
  browserVersion: {};
  userAgent: {};
  appVersion: {};
  platform: {};
  vendor: {};
  osName : {};
  clientList: client[]

  clientListLoading: boolean = false;
  orgMail: any;
  user: any;


  constructor(public clientService: ClientService,private store: Store<AppState>,
     private fb: FormBuilder,
    private emailService: EmailService) {
    store.select('client').subscribe(clients => this.clientList = clients.filter(cli => cli.enabled == 0))
    this.user = JSON.parse(localStorage.getItem('user'))
    console.log(this.user);
    {
        this.createForm();
      }


   }

   createForm() {
    this.angForm = this.fb.group({

      email: ['', Validators.required],
      message: ['', Validators.required],
    });
  }
  sendMail(name, email, message) {
    this.emailService.sendEmail(name, email, message).subscribe(success => {

      console.log(success);
    }, error => {
        console.log(error);
    });
  }

  ngOnInit() {
    // this.browser_details();

contact.js

const express = require('express');

server.js

// server.js
const express = require('express');
const bodyParser = require('body-parser');
const cors = require('cors');
const path = require('path');
const app = express();
// CORS Middleware
app.use(cors());
// Port Number
const port = process.env.PORT || 3000
// Run the app by serving the static files

app.use(express.static(path.join(__dirname, '/majeni/dist/majeni')));
// Body Parser Middleware

// Start Server

This my email.service.ts

import { Injectable } from '@angular/core';
import { Headers, Http, Response } from '@angular/http';

@Injectable({
  providedIn: 'root'
})
export class EmailService {

   constructor(private http: Http) { }

  sendEmail(name, email, message) {
    const uri = 'http://localhost:4200/support/contact';
    const obj = {
      name: name,
      email: email,
      message: message,
    };
    return this.http.post(uri, obj);
  }
}

You should not use two ports on contact.js and the port 465 is the port secure so replace:

       port: 465,
       secure: false,
       port: 25,
       auth: {
           user: 'email',
           pass: 'pass'
       },
       tls: {
           rejectUnauthorized: false
       }

for:

      port: 465,
      secure: true,
      auth: {
        user: email,
        pass: pass
      }

On the variables email and pass you should set the email and password of account who go sent the email (I recommended create a new email account just for the form contact because gmail accounts by default not allows clients login without set up DMARK e DKIM) and always make sure to keep this informations out of public code repositories like GitHub.

You can see a similar code who I did on my github: https://github.com/anajuliabit/my-website-backend/blob/master/src/Controllers/ContactController.js
