In Angular, you typically develop client-side applications, which means that the IP address of the client (the user’s device) is not readily available within the Angular application itself. However, you can retrieve the client’s IP address by making a request to a server-side endpoint that captures the client’s IP address. Here’s a general approach to achieving this:
- Create a Server-Side Endpoint: You need to set up a server-side endpoint (API) that will capture the client’s IP address and return it to the Angular application. This endpoint can be implemented using any server-side technology such as Node.js, PHP, Python, etc. The server receives the HTTP request from the client, extracts the client’s IP address from the request headers, and then sends it back as a response.
- Make an HTTP Request from Angular: In your Angular application, you can make an HTTP request to the server-side endpoint created in step 1 to retrieve the client’s IP address. You can use Angular’s
HttpClient
module to make the request. Once you receive the IP address response from the server, you can then use it within your Angular application as needed.
Here’s a simplified example of how you can achieve this:
Server-Side (Node.js Express) Example:
const express = require('express');
const app = express();
app.get('/get-ip', (req, res) => {
const clientIp = req.ip; // Extract client's IP address from request
res.send({ ip: clientIp });
});
app.listen(3000, () => {
console.log('Server is running on port 3000');
});
Angular Example:
import { Component } from '@angular/core';
import { HttpClient } from '@angular/common/http';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
clientIp: string;
constructor(private http: HttpClient) {
this.getClientIp();
}
getClientIp() {
this.http.get<any>('/get-ip').subscribe(
response => {
this.clientIp = response.ip;
console.log('Client IP:', this.clientIp);
},
error => {
console.error('Error fetching client IP:', error);
}
);
}
}
Here are one more practical scenario to get Visited client IP address in Angular
!. Create one service so that we can access code thr out application
-
import { Injectable } from '@angular/core'; import { HttpClient } from '@angular/common/http'; @Injectable({ providedIn: 'root' }) export class clientService { constructor(private http: HttpClient) { } public getClientIPAddress() { return this.http.get("http://api.ipify.org/?format=json"); } }
- Go to your component ts file like header.component.ts. Add service file and create alias of service to fetch getClientIPAddress method
import { Component, OnInit } from '@angular/core'; import { clientService } from './client.service'; @Component({ selector: 'app-header', templateUrl: './header.component.html', styleUrls: ['./header.component.css'] }) export class HeaderComponent implements OnInit { constructor(private clientService:clientService){} title = 'Get client IP'; clientIP:string; ngOnInit() { this.getClientIP(); } getClientIP() { this.clientService.getClientIPAddress().subscribe((res:any)=>{ this.clientIP=res.ip; }); } }
3. Now you can use this.clientIP in header to show on header
<div>{{clientIP}}</div>
