How to allow access outside localhost

问题:

How can I allow access outside the localhost at Angular2? I can navigate at localhost:3030/panel easily but I can not navigate when I write my IP such as 10.123.14.12:3030/panel/.

Could you please allow me how to fix it? I am not using npm (node project manage - node install/node start ) to install and run the project.

If you want, I can provide my package.json and index.html.

回答1:

Using ng serve --host 0.0.0.0 will allow you to connect to the ng serve using your ip instead of localhost.

EDIT

In newer versions of the cli, you have to provide your local ip address instead

EDIT 2

In newer versions of the cli (I think v5 and up) you can use 0.0.0.0 as the ip again to host it for anyone on your network to talk to.

Mac users:

1. Go to System Preferences -> Network -> Wi-Fi
2. Copy the IP address below Status (Usually 192.168.1.x)
3. Paste it in your ng serve like: ng serve --host 192.168.1.x

Then you must be able to see your page on other devices through 192.168.1.x:4200.

回答3:

run command-" ng serve --host=0.0.0.0 --disable-host-check "

this will disable host check and allow to access from outside(instead localhost) with ip address

回答4:

You can use the following command to access with your ip.

ng serve --host 0.0.0.0 --disable-host-check

If you are using npm and want to avoid running the command every time, we can add the following line to the package.json file in the scripts section.

"scripts": {
    ...
    "start": "ng serve --host 0.0.0.0 --disable-host-check"
    ...
}

Then you can run you app using the below command to be accessed from the other system in the same network.

npm start

I just edit angular.json file in my project as below and it works

...

    "serve": {
      "builder": "@angular-devkit/build-angular:dev-server",
      "options": {
        "browserTarget": "project:build",
        "host": "0.0.0.0"
      },

...

you can also introspect all HTTP traffic running over your tunnels using ngrok , then you can expose using ngrok http --host-header=rewrite 4200

回答7:

Open cmd and navigate to project location i.e. where you run npm install or ng serve for the project.

and then run the command - ng serve --host 10.202.32.45 where 10.202.32.45 is your IP address.

You will be able to access your page at 10.202.32.45:4200 where 4200 is your port number.

Note: If you serve your app using this command then you won't be able to access localhost:4200

For the problem was Firewall. If you are on Windows, make sure node is allowed through

回答9:

Use this :

ng serve --host 0.0.0.0 --port xxxx

回答10:

For the people who are using node project manager, also this line adding to package.json will be enough. For angular CLI users, mast3rd3mon's answer is true.

You can add

"server": "webpack-dev-server --inline --progress --host 0.0.0.0 --port 3000"

to package.json
