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.

I use vuetify (vue)
Is it mandatory for each deployment to production for remove node modules and run npm install? Or just run npm run build?
I have two option :
Option 1 : Every deployment, I run the npm run build directly
Option 2 :
Delete the contents of dist folder
Delete node_modules folder
npm install
npm run build
Which is the best option?
npm install
This command installs a package, and any packages that it depends on. If the package has a package-lock or shrinkwrap file, the installation of dependencies will be driven by that, with an npm-shrinkwrap.json taking precedence if both files exist. See package-lock.json and npm-shrinkwrap.
If you did not install or update the package before releasing the project, you do not need to execute npm install, otherwise, you need to execute it to ensure that dependent packages on the production environment is consistent with your local dependent package version.
If you are using an automatic build deployment tool like jenkins, for convenience you can execute the install command before each build. It's okay.
Imagine more environments, not just a production:
development
testing1
staging
uat
production
Can we upload the npm run build result (compressed js) or node_modules to our git repository? ANSWER IS NOT!!. So if you need to have a version of your app running in any of these environments, you must to execute npm run build. And this command needs the classic npm run install. I think this last sentence, answer your question.
(ADVICE) Docker to the rescue
assumption 1 your client-side app (vue) is not complex(no login, no session, no logout, etc ), you could publish it using a basic nginx, apache, basic-nodejs.
assumption 2 you are able to have one more server for docker private repository. Also if you are in google, amazon o azure, this service is ready to use, of course a payment is required
In one line, with docker you must execute just one time npm install and npm run build. Complete flow is:
developer push some changes to the git repository
manually or automatically a docker build in launched.
inside Dockerfile, npm install and npm run build is executed. Also a minimal server with nodejs (example) is configured pointing to your builded assets
your new docker image is uploaded to your docker private repository
that's all
If your quality assurance team needs to perform some tests to your new app, just a docker image download is required. If everything is ok, you pass to the next stage (staging or uat) or production. Steps will be the same: just download the docker image.
Optimizations
Use docker stages to split build and start steps
If your app does not have complex flows(no login, no session, no logout, etc ), replace node basic server with a simple nginx
I need login and logout
In this case, nginx or apache does not helps you because they are a simple static servers.
You could use a minimal nodejs code like this:
https://github.com/jrichardsz/nodejs-static-pages/blob/master/server.js
Adding /login , /logout, etc
Or use my server:
https://github.com/utec/geofrontend-server
which has a /login, /logout and other cool features for example: How are you planning to pass your backend api urls to your vue app in any of your environments?.
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
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.
We just finished developing a node.js application which includes a Restful API and a Mssql database .
I will need to deploy the app in in-house servers of companies having Windows 2008 and windows 2012 environments
What i want to achieve :
The best case is to make the deployment in an one-step procedure .
What i m currently doing :
Clone the project in a dir
Run npm install ( Best case scenario is to have all dependencies in a folder to avoid problems with versions or npm )
Deploy the db using a script
Start processes with pm2 process manager
Is there anyway to pack all these steps in a simple step ?
Something alternative to docker for example ? (I can't use docker because is not compatible with most of the OS )
Is there anyway to pack all these steps in a simple step ?
Yes. You can write a script that does all of that for you.
Even without writing such a script you can combine the first two steps easily. To simplify the first two steps you could make your project globaly installable with npm install --global. You could install your project that is hosted on GitHub just by doing:
npm install -g username/repo
and it will install your project and all of its dependencies.
You could also use a private package on npm or even a private npm registry for that.
You could install both the start scripts and the db deploy scripts that way as well in a single step, because your module can install multiple executables.
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.
