If I am running a local server that is hosting a video chat application what is the best way to test the application with another user? Lets say I have two computers, is there a way I can allow computer B to connect to the local server that is running on computer A? The goal is to simply test whether the video chat application works properly in two completely different browsers running on separate computers. If there is a way I can trick the app into thinking the computer that is running the local server is another host, please let me know.
But Remember that the app needs access to the computers webcam. Thanks!
Addition Info: Nodejs application that uses the Tokbox, express, and socket.io APIs
Just make sure your web server is listening on a routable IP like "0.0.0.0", which you specify when you call http.createServer(port, ip, handler). Then point the browsers at the server's IP address such as http://192.168.1.1:3000 (fill in your specific IP and port). You can use the command ifconfig -a on linux or osx to get your server's local IP address, and ipconfig on windows.

A node js server is running on localhost on my PC. I am connecting this server to a mobile app with some IP(192.168.0.120:8044) for API requests. I am sharing this IP address by scanning a QR code in my desktop electron app by mobile application. So the first time I am able to get the server's IP by QR.
But when my Desktop boots again. The private IP might change to maybe 192.168.0.121
Is there any way in node.js to make this private IP static so my mobile device can always know where to send all API requests?. like creating a custom subdomain locally not exposed to the internet?
I know I can just go to the PC's setting and make Ip static. But in production, it might be a big issue to ask users to do so.
While it may be possible to go into the computer's config programatically and make the IP static, it would be better to structure the application not to require such a thing.
Since the client initially connects to the server with a QR code, you could have the server embed its hardware MAC address in the code, instead of (or in addition to) the server's IP. On the client, save the MAC address in the app's permanent storage.
Then, to connect to the server from the client, search through the LAN's ARP table to identify which (if any) IP addresses have that MAC address. If so, you've found it - if not, the server is offline.
I am working on a swift project for osx with Firebase. I have a node web server to communicate between the clients and the Firebase-server, but it's a localhost-server. Do I need a real domain name to make the server accessible to end-users on another device? (I don't want a web app, just the backend for myself)
you doesn't need a domain .. but you need a serve to deploy having ip address .. suggestion you can use cloud server
You have two ways:
make request on port that the nodejs uses, example http://101.01.01.01:8000
use nginx like proxy, in this setup make your requests on 80 port (it's default), example http://101.01.01.01.
If you wont make something like dev environment on local machine use first case (don't forgot open port for other devices), for production - second.
I'm using node js trying to send my web-page to my network, I successfully call localhost:port in my computer using express as server, the webpage loads fine trigger my webcam which I used to streaming in the webpage, and then im working to make a simple app in my phone to directly access my server, so my questions:
1.How do I able to access my server from different devices in the same wireless-network? by calling ip + port ?192.168.1.104:9001 ? cause i've tried and it didnt work.
2.I've found https with .pem something like that, is that the answer ? is there also any other way ?
3.maybe any advice before i work to make my web-app to devices? using koa? i don't even really know what is that, but i'm happily take any advices.
EDIT: i've read How could others, on a local network, access my NodeJS app while it's running on my machine?
let's say I simply using random router, so i can't configure my router-port, my server in my pc and my phone join in the same network, trying to access the server in my phone
1.How do I able to access my server from different devices in the same wireless-network?
All you need to do is find your server's IP address in this same wireless-network, and find the Node.js application's port. Then access the following URL in other devices:
http://{server_IP}:{port}
However, there are some points need to check:
Need to check firewall and confirm the port is not blocked, server IP is not blocked by test device, and test device IP is not blocked by server.
Need to check whether there is any Proxy setting in server and test device. If there is any, disable the proxy.
A computer may have many IP addresses at the same time, you need to find the correct one in the same wireless-network. For example, If you install a virtual machine software such as VMware and run a virtual system inside, your real computer will get IP address as 192.168.*.* -- this IP address looks like an intranet IP in wireless-network, but it is not, and can never be accessed by test device.
2.I've found https with .pem something like that, is that the answer?
No, HTTPS has nothing to do with this problem. HTTPS just add security (based on HTTP layer), it does not impact any HTTP connectivity. Actually, to minify the problem, it is better to only use HTTP in your scenario.
There is only one very special case that may bring your problem by HTTPS -- the test machine is configured and will block any non-HTTPS connection for security.
3.maybe any advice before i work to make my web-app to devices? using koa?
My suggestion is: As there is an HTTP connectivity issue, the first step is trying to find the root cause of that issue. Thus, it is better to make a simplest HTTP server using native Node.js, no Koa, no Express. In this way, the complexity of server will be reduced, which makes root cause investigation easier.
After the HTTP connectivity issue is fixed, you can pick up Koa or Express or any other mature Node.js web framework to help the web-app work.
4.let's say I simply using random router, so i can't...
Do you mean your server get dynamic IP address by DHCP? As long as the IP is not blocked by test device, it does not matter.
Background
I am building a site using angularjs and want to make sure that its displaying properly on my phone. I'm aware of the Google Chrome emulator but would like to show people it directly on the phone.
Node.JS
I'm using http-server . to run a server at the base of my app. This was the quickest and easiest way of getting a server for local testing.
I have tried going onto the same network via wifi on my phone and then trying to get to localhost:8080 but it just gives me a "this web page is not available" error
Question
My question is, is there a way to get my web app on my phone with http-server . or do I need to set up a proper web-server? I thought maybe it would just be simple to get it on any device attached to the same network.
Since our application(server) and devices(in which you want to access the application) running on same network.
You can access this with the help of IP address.
Let say, your app is running on
192.168.1.1:3000
So you can access it as localhost:3000 on local machine.
And as 192.168.1.1:3000 on devices which is using the same network.
any device can access to server. Use ip in device not use localhost
Use ngrok https://ngrok.com/ , ngrok expose your localhost behind a NAT or firewall to the internet , easy to use , after install just type on command line ;
ngrok 7070
then it gives you a link like ; 3g87g9g.ngrok.com
Use ifconfig utility if you are in linux or use any other tool to get the ip address of your phone (Web server), for example 192.168.1.10 is IP address of the phone.
You can access the web page from any other device in the network by going to 192.168.1.10:8080 in the browser.
Note that 8080 is the port to your server application, you select the port from node.js
i want to add lan support to tic-tac-toe game which is a HTML5 canvas based, so that two players can easily play. how can i do it using javascript/node.js?
OK, I'm assuming all of your HTML5 game is finished and you're distributing it with the server that hosts it. (Otherwise you're stuck to just the browser, which can't do all the awesome node.js net stuff, I am describing.)
NB: You need to have node.js running on both clients. Otherwise you can't do LAN-only without a central server's involvement.
One of your clients has decided they want to host a LAN game
The node.js server running on that client starts to listen on a port
That server find out its local IP Get local IP address in node.js
Options:
Your players can manually tell each other the IP of the hosting server
Your hosting server sends out broadcast messages to its local subnet, informing them that it's hosting a game
Your other client server scans for IPs in its local subnet to find any hosting gameservers (Tries to open the pre-determined port your hosting server is listening on.)
The other node.js client opens a connection to the hosting server.
Done.
