How can I install nodejs modules to appfog - node.js

Normally in local, I use cmd, command line to install any nodejs module using "npm install testing or connect or etc.."
But I decided to use appfog as server and I add nodejs to my project on appfg but probably I am gonna need some nodejs modules like testing, connect, request etc..
The problem is I couldnt found tool like cmd on appfog or any way to add nodejs modules.
How can I do this?

Basically, you just need to install the dependencies in your local environment and everything should be just fine. Simply specify all of your dependencies in your package.json file, run a typical npm install, and if the modules are properly installed in your local environment then they will be pushed to AppFog when you run af update.

You just have to develop your application on your local machine with all the required dependencies in the json package and modules in the Node.JS. And if your application is working properly at that time on your local machine then you can push all that application data to the AppFog using command line interface. Simply use the command af update <your app name> Then start the application and you will see that everything is working properly.

Package and run nodejs application in an offline server

I'm currently using NextJS and to run a production build, I use npm run build followed by npm run start. This all works well on my local machine.
However, I need to deploy this app on an offline machine where I may not have an internet connection to install all the node packages.
I've taken a look at npm pkg and npm pack utilities, but not quite sure which is the best one to use in the context of a nextjs app.
Would appreciate any advice on the best way to do this.
Edit: thinking along the lines of how I would build my maven project and have a .jar output which I can use to deploy to any other machine as a single deployable file.

Install React JS on Cent OS

I am very very new to React JS and have tried to install it on my VPS server that is running Cent OS.
Node.js seems to be working,
I have build a React project using the following code as a root level user on SSH:
npx create-react-app my-react-project
cd my-react-project
npm start
but when trying to view in browser I get a blank page (instead of react js default template)?
I see many people install this locally but I haven't found any examples on a hosted VPS, is this something I am doing wrong?
Any help would be much appreciated, thanks!
if you have ssh access to your VPS, the rest is pretty the same as your local environment.
You can copy/paste your project to your CentOS host and use the following commands in order to run it:
cd your_project_folder_which_includes_package_json_file
npm install
npm start
Also, if you are using this server as a production host, You should consider getting a production build of your React app on your local env by running npm run build and then publishing the build folder on your server and serving it using a static file server or using a reverse-proxy such as Nginx as a static server.
Actually this page in React documentation does a good job in explaining the details of deploying a React app, I encourage you to take a look at it.

How to install and deploy node.js application?

I'm new to node.js. After creating modularized project with express, tests, .nvmrc etc. it's finally time to deploy the app. How it should be done? in java you bundle your project into a single file, self containing and you put in into a server with some configuration. what about node.js?
Should i just copy the whole directory with sources and node_modules to production machine and use systemd, pm2 or other process manager to just run it? but i heard some of the dependencies might be system-dependend so they may work incorrectly
or should i copy only sources and run npm install --production on the production machine? but this way the deployment is only possible when npm repositories are online. also it takes time to build the application and it has to be done on all machines in the cluster. also what about quickly rolling back to previous version in case there is some bug? again, time and online npm repos are needed
another option is to build a docker image. but it seems awkward that the only way to easily and safely deploy the app is using third party technology
how it's being done in real life scenarios?
sure don't copy the whole directory especially node_modules.
all the packages installed on your system should be installed with --save option example: npm install --save express if you do so you will have in your package.json the dependencies required for your project whether they are dev dependencies or production dependencies.
I don't know what your project structure looks like, but as a node application you have to run npm init . in your project to setup the package.json file and then you can start adding your dependencies with --save.
usually we use git
version control system
to deploy to the server, first we push our code to a git repository then we pull from it to the server git
you have to add .gitignore in your project and ignore node_modules from being committed to your git repository.
then you can pull to your server and run npm install on the server. and sure you need to launch your web server to serve your application example ngnix
you can try Heroku for an easy deployment, all you have to do is to setup your project with Heroku, and when you push your code, Heroku manages the deployment . Heroku

How to deploy Nestjs App (on Azure)?

I am trying to deploy a Nestjs API (with Auth0 authentication). When I run it in VS Code with npm run start:watch server, everything's fine.
Now the question is: what should I do to deploy it on a webserver? Should I only copy the dist folder (after runnin tsc)? what about node_modules? Should I leave the port to 3000?
As a side note I am trying to deploy it on Azure but I guess the questions holds for any platform.
Many thanks!
Modify your package.json file, and add a postinstall script, this script should be tsc or tsc --sourceMap false if you would like to avoid sourceMaps from being generated.
That would make azure to run tsc after installing all npm packages, remember to change start script also, so its value is 'node dist/index.js'

Installation of vue-cli : how does it work?

I'm very new to Node Package Manager and also Vue, and I'm trying to understand what exactly is going on with using the Vue CLI.
The vue.js website has this as instructions for running the official Vue CLI:
I have a few questions about this:
Does npm install --global vue-cli need to be executed only once on a machine, or once on a directory, or once per new project you're starting? In other words, once it's on your computer, is that the last time you need to run that command, or do you need to execute this command every single new project you start?
Once a new project is initiated, are local copies of the newest version of vue (and vue-router, if selected) installed?
If I finish this project and want to deploy it, how do I then port this over to a production server?
Once in a machine, except for the rare cases where one is isolating one's npm install (such as by using nodeenv or inside a container); that's what the global option is for.
After running npm install, yes.
Running npm run build and copying the contents of the resulting dist directory to the production machine (often within a /var/www directory or similar). This can be automated further in many ways.
