I am using nodejs http-server for a web application. I am able to launch the http-server by running nom start. I can access my server through http://127.0.0.1:8080 but I can't connect by http://localhost:8080. I have checked that localhost can be ping from my terminal and localhost works fine with other server such as tomcat. So I think the problem relates to http-server only. Is there any configuration I need to setup on my application in order to support localhost access?

I am trying to get my nuxt app working on the production servers. For the local machine, the generated docker image runs well and it can access the nodejs app that runs on localhost. The axios 'baseurl: http://127.0.0.1:6008/' seems working fine, the docker image can access this. On the production servers, i have used docker to setup the nuxt app, the same way i tested on my local machine. Yet the docker nuxt app cannot reach the nodejs app on the host server. I can see this must be some kind of network setting issue.
In vuejs app, i usually setup a proxypass in the apache web conf, to convert the input backend query to match and replace them with localhost address.
ProxyPass /app/query http://localhost:6008/query
The nuxt.config file, axios setting looks lik this:
axios: {
baseURL:'http://127.0.0.1:6008/',
browserBaseURL: ''
},
Does docker needs additional settings or should i configure my apache for this communication between my docker container and a node app that running on host apache pm2 ?
localhost or 127.0.0.1 from within the docker will not resolve to the server's localhost. Instead you need to specify the name of the nodejs service (if you are using docker-compose) or the nodejs docker container name (if you are just using docker run).
You can also try by giving the IP of the server where the docker is running instead of 127.0.0.1
I've both NodeJS and AngularJS applications. I'm using npm install to download the app's dependencies for both the application. The NodeJS application runs on port 4000 and AngularJS application runs on port 4200. I can access APIs from NodeJS application in the browser and cannot access the application's UI(AngularJS) in the browser. I have deployed these applications on Azure Virtual Machine.
I have opened the ports 4000 and 4200 in the network settings of Azure VM. I'm using npm start command to start both the applications. NodeJS working fine as like in the local machine but not the same case with AngularJS. There is no errors or warnings from AngularJS side. It shows that the app is listening on http://localhost:4200/ and it is not accessible.
In this case, you need to run ng serve --host 0.0.0.0 to allow that your AngularJS application is listening on 0.0.0.0 for outside connecting. You could refer to this How to allow access outside localhost
Try using:
ng serve --open --host 0.0.0.0 --disable-host-check
I created my App from this boilerplate
https://github.com/Bikranshu/express-react-boilerplate
Now I uploaded it to a live Linux server and Node server is running.
Screenshot of running server
But I am unable to access it through Browser with IP address of server.
http://ip_address:3000
After waiting long in browser it is showing timeout error.
Please guide me how can I access the node/react app from browser.
Server running at <ipaddress> is a local IP, are you in a different network than the server? If so, you should be typing https://<public ipaddress>:3000
UPDATE
Hosting services usually only forward port 80 (http) or 443 (https.) This means that your port 3000 is not allowed for public access. To fix your problem you need to change the listening port.
Check line 42 on
server/app.js change 'port' to "80" or check package.json and edit npm start to set port to 80
I guess I will start at the start of my application.
I am making a full mean-stack application and I want it to run in docker. To use docker I am using a virtualbox with Ubuntu. When I run my docker-compose, everything is working on localhost:4200. Now I want to open my application on my host machine (Windows 7).
When I go to my application via (ip addres should be kept secret, right?) xxx.xxx.xx.xxx:4200/login the page looks fine, but I get these errors:
I am using Angular cli 1.4.1 with node 8.4.0
Why am I getting these errors and how do I fix them?
My docker-compose
Your server which is listening on port 4200 is listening on your xxx.xxx.xxx.xxx interface (not necessary to hide lan IP, but nevermind...).
Your angular application is running on your host system. the localhost is the localhost of your host system, not the guest. so you have two solutions:
changing your urls inside the angular application to point to xxx.xxx.xxx.xxx:4200 instead of localhost:4200.
Forwarding your 4200 port from your host to your guest system using virtual box :
shutdown guest.
select guest and click on settings
go to the network tab.
click on "advanced"
then select "ports redirections" and bind your host 127.0.0.1:4200 to your guest's 4200 port
I have built a simple web app using angular-cli 2,it works well in the local machine. now i tried to deploy it onto a digitalocean server,
however when going to the web server link with http://ip address:4200, i can't visit the web app.
Note: I can make sure the firewall is open to the web application on that port since in ufw status shows 4200 ALLOW Anywhere
You need to serve the actual ip address of the server, by default ng serve will use the loopback address. You can achieve this with:
ng serve --host 0.0.0.0
