I am having trouble accessing my Angular2 application outside of localhost. I can easily navigate to localhost:3030/panel, but when I try to use my IP address like 10.123.14.12:3030/panel/, it does not work.
Can someone please help me fix this issue? I am not utilizing npm (node project manager - node install/node start) to install and run the project.
If needed, I can provide my package.json and index.html.
If you run ng serve --host 0.0.0.0, you can access the ng serve using your IP address instead of localhost.
UPDATE
In more recent versions of the CLI, you must specify your local IP address.
UPDATE 2
With newer versions of the CLI (probably v5 and above), you are able to again use 0.0.0.0 as the IP to host it for communication with anyone on your network.
execute the following command
ng serve --host=0.0.0.0 -disable-host-check
By running this command, you can disable host checking and access the application from outside using the IP address instead of localhost.
Attention Mac users:
ng serve --host 192.168.1.xAfter completing these steps, you should be able to view your page on other devices by entering 192.168.1.x:4200.
To access your IP, use the command provided below.
ng serve --host 0.0.0.0 --disable-host-check
If you prefer using npm and wish to avoid entering the command repeatedly, simply include the following line in the scripts section of your package.json file.
"scripts": {
...
"start": "ng serve --host 0.0.0.0 --disable-host-check"
...
}
After adding the line, run your application using the following command to allow access from other systems within the same network.
npm start
I successfully made changes to the angular.json file in my project, and it's now functioning as intended.
...
"serve": {
"builder": "@angular-devkit/build-angular:dev-server",
"options": {
"browserTarget": "project:build",
"host": "0.0.0.0"
},
...
There is no need to modify the package.json.
You can simply run the following command:
ng serve --host=0.0.0.0 --port=5999 --disable-host-check
Access your application at: http://localhost:5999/
The issue turned out to be a Firewall problem. Windows users should ensure that node is granted permission to pass through the firewall.
If you're working with Angular version 11 (or possibly a few earlier ones), using the --public-host option could be just what you need. Here's an example:
$ ng serve --host 0.0.0.0 --public-host app.mypublicdomain.com
If you encounter the same issue within a Docker environment, you can solve it by using the following command in your Dockerfile.
CMD ["ng", "serve", "--host", "0.0.0.0"]Alternatively, you can utilize the complete Dockerfile provided below:
FROM node:alpine
WORKDIR app
RUN npm install -g @angular/cli
COPY . .
CMD ["ng", "serve", "--host", "0.0.0.0"]
ng serve --host 0.0.0.0 enables you to access the ng serve using your IP address instead of localhost.
Simply type in your browser <IP-ADDRESS>:4200
If you use
ng serve --host 0.0.0.0 --disable-host-checkJust open your browser and enter <DOMAIN-NAME>:4200
To begin, launch cmd and go to the directory where you typically install npm or run ng serve for your project.
Afterward, enter the following command - ng serve --host 10.202.32.45 with '10.202.32.45' representing your IP address.
Your page will be accessible at 10.202.32.45:4200, where 4200 is designated as your port number.
Please take note: If you utilize this command to serve your app, you will no longer be able to reach localhost:4200
If you're looking for a quick fix, try this solution:
Insert the following line with the specified value for start
ng serve --host 0.0.0.0 --disable-host-checkpackage.json
For example:
{
"ng": "ng",
"start": "ng serve --host 0.0.0.0 --disable-host-check",
"build": "ng build",
}
Then simply use start or npm run start
This should allow you to access your project from other local IP addresses.
One option is to analyze all HTTP activity flowing through your channels with ngrok , after which you may reveal by utilizing
ngrok http --host-header=rewrite 4200After implementing the ng serve --host 0.0.0.0 command, my problem was successfully resolved. To access the application from a different machine, use the IP address 192.168.x.x:5200.
Additionally, ensure to review any firewall restrictions on both the client and server sides (either temporarily disabling the firewall or setting up a rule to permit traffic).
To initiate the server, run
.ng serve --host<Your IP> --port<Specify if needed>
For example, type in: ng serve --host=143.22.1.54 --port=8080.
After compilation, you will see the following message displayed below.
The Angular Live Development Server is now running at 143.22.1.54:8080. Open your preferred browser and go to
http://143.22.1.54:8080/**.
ng serve --open --host 0.0.0.0 --disable-host-check
Executing this command worked flawlessly for me, even when utilizing a public IP with an A host directed to that specific IP address.
Make a new file called proxy.config.json and insert this setup:
{
"/api/*":
{
"target": "http://localhost:7070/your api project name/",
"secure": false,
"pathRewrite": {"^/api" : ""}
}
}
Replace the following line of code:
let url = 'api/'+ your path;
To execute from the command line interface, type:
ng serve --host port.number —-proxy-config proxy.config.json
Personally, I find success with the command "ng serve --open --host 0.0.0.0", but a warning does come up
CAUTION: This server is designed for testing or debugging Angular applications locally. It has not undergone thorough security checks.
Running this server on an open connection can potentially compromise your application or device. Using a different host than what was specified in the "--host" flag may cause websocket connection problems. In such cases, consider using "--disableHostCheck" as a workaround.
Those utilizing the node project manager can simply include this line in their package.json file to achieve the desired outcome. However, for users of angular CLI, it is recommended to follow mast3rd3mon's solution.
The following code snippet should be added:
"server": "webpack-dev-server --inline --progress --host 0.0.0.0 --port 3000"
This addition should go into the package.json file.
