I run an NodeJS server with an website on Bluemix. In addition I use the embedded Node-Red module (http://nodered.org/docs/embedding.html) to run a Node-Red server in the background to use it on my website.
Now I want to add/update my custom nodes while the server runs.
Working Environment: Bluemix, Node.JS Express 4, Node-Red module
I would appreciate any help on this.
The Node-RED runtime includes an admin api that allows you to install nodes whilst the system is running.
See: http://nodered.org/docs/api/admin/methods/post/nodes/

Developers i'm a nodejs developer with a experience of 1.5 years working in the company my question is i'm doing a project which is called a virtual classroom like a webinar platform where chat support, drawing and etc functionalities are available, so from last 2 month had been done of working in project i had gone through the each component directory and file with it's documents also they have used of docker, redis, proxy server, nginx, session, mongodb these kind of services and it's working fine on server end side but can't able to stablish on my local machine and it's a linux based project where have numbers of powershell files with PM2 library to make it run... so i followed a docs with some code also i success to make the service on and registered a local domain also in hosts file or nginx custom configuration it is working fine... but when i hit my ulr on browser with the local domain it not going to any of the route....
Example - like if we make a node simple project with hello world and it will working on 4500 port so we write localhost:4500 and it will print our responce on browser
but if the run my project through a PM2 or a simple node app.js bcoz this app.js have connected with all nodes services and virtual classroom and you the linux platform we don't need to make serivice on it's by default in runing state monogoDB, redis, docker, nginx but the real question is while firing the command node app.js it shows some json and told port:2178 but when in hit this on browser localhost:2178 not responce to GET request why??? but there is route called localhost:2178/landing/session/v1/classid(which is encrypted code) this url not working what to do ??
I am trying to learn how to use Node.js and web sockets to create simple multi-user interactive javascript programs. I used this tutorial series by Daniel Shiffman to create this example project. My next step would be to upload it, using WinSCP, to my RaspberryPi apache2 web server, but I haven't found a way to edit the code in a way to allow for that to work, and furthermore, I do not know what piece of the programs to execute to make it function properly.
Any assistance would be great. The extent of my Node / Socket.io knowledge comes entirely from the video series mentioned above, so you can assume I know almost nothing else.
Apache is a web server and it serves your file and send them to client for you, so when you have some client side things like html site with some css, javascript and images you can use apache to send them to client for you.
In node.js you can create this web server simply by following code and express library:
// Create the app
var app = express();
// Set up the server
var server = app.listen(3000, () => {
console.log('http server is ready')
});
as you created in your code too. by this web server you can host your files and do many more things like setup socket.io server and ... because you write web server yourself. with following code you serve static files in public directory (html, css, javascript and images ...):
app.use(express.static('public'));
after you finishing this process you can run it simply by:
npm install
node server.js
if you want you can run you code inside docker by creating Dockerfile and ...
About your question, you must move all your project files into raspberry and at the end you have following directory tree in somewhere in raspberry:
|- server.js
|- package.json
\ public
at this directory run above commands and your server will be up and running and you can access to it by http://raspberry_ip:3000.
I'm working on a project where I need to have multiple node clients connect to a node server via websockets. The clients will send files to the server and the server will immediately distribute that file to all connected clients.
The problem I'm running into is connecting as a client in node. The built in ws module seems to only support server use. I've also tried the npm websocket client which allows me to use node as a client but I seem to only be able to send binary data without any other information like the filename, etc. using the sendBytes method.
Thanks for any suggestions.
Checkout the delivery package of npm.
It provides bi-directional file tranfer for node.js over socket.io.

I have node.js installed on Vagrant and WebStorm access to a project on shared folder via VirtualBox.
Can I run node.js application on WebStorm and see the output on WebStorm (Terminal or SSH)? At the moment I have to keep switching to Putty to run it to see the output, its gets quite tiring.
Running Node.js applications remotely is not currently supported, please follow WEB-6136 for updates.
Debugging remote applications is possible (using Node.js Remote Debug run configuration - see https://confluence.jetbrains.com/display/WI/Running+and+debugging+Node.js+application#RunninganddebuggingNode.jsapplication-DebuggingNode.jsappthatrunsremotely). But you can't see the remote process output in WebStorm console, as Stdout of it is not accessible via debug protocol WebStorm uses for remote debugging. Related feature request: WEB-17013
This feature is available through ssh on Webstorm 2017.1

I have a remote host on an ovh server that I can access with FTP and SSH.
I have a nodeJs backend that runs on this remote server.
I want to build, deploy and run this nodejs server on the remote host from TeamCity.
Actually, I can build the project with TeamCity and it works well, build passing or failing if I have wrong confirations.
Question :
How can I deploy and run my nodejs server , after the building steps, directly within teamcity ?
Thanks for advance
You can create a teamcity remote agent on the target host that you can use to deploy the built code.
you can create a teamcity target that will ssh to the target host and deploy your artefacts generated in the build.
You can get the artefacts from build -> deploy either through teamcity artefacts or through mounted disk volumes(nfs disks)
