I need some help with the following situation:
At the moment I am working with Maven and Spring in order to do a web application. My team was working downloading the dependencies for different frameworks, but now I want to use npm to make the dependencies managment easier.
When I run npm install it downloads the dependencies locally, but the idea is not to upload the node_modules folder to git or the web, is to have the package.json file and download them manually in each computer.
I know that the app is compressed in a war file (I don't know when and how, when I started working here that was working like that), and when is compressed it downloads the maven dependencies (or that is what I understood). I want to make the same with the npm dependencies, the idea is to configure somewhere that it has to run npm install before compressing the whole application.
Does anyone know how to do that? I hope that you could get the idea.
Thank you!
Assuming that for war packaging Maven war plugin is used - you cannot invoke npm command from it.
Note: When using the war: goals it is assumed that the compile phase is already done. The WAR Plugin is not responsible for compiling the java sources or copying the resources.
https://maven.apache.org/plugins/maven-war-plugin/usage.html
As workaround for endpoint you can install required modules by npm install -g if your server have the access to npm repo. Otherwise you need to copy node-modules manually.
Don't forget about the permissions.

Hi We are using jenkins and have a step in pipeline where we download dependencies such as mocha, cucumber etc. using
npm install
The client jenkins is not having internet access nor they have any dependency management server such as artefactory.
Is it possible to bundle the required dependencies from node_modules in zip or tar form and the same can be imported by them in global scope. So there is no need to run npm install for each job and they are available as global packages.
Is it that each project such as cucumber etc. needs to be downloaded separately and imported as file path.
Please share your thoughts as I am not able to find much information on what appeared to be a common problem initially with Organizations generally not allowing outbound internet on their servers.
thanks !!
Have a look at npm-pack-all that packs all of the node_modules as part of the artifact.
I have to create a zip file of my whole nodejs server app.
I should be able to unzip it and run it, without installing dependencies and apps.
It should not be a binary file.
The dependencies should be flattened.
How to do this thing ?
Generally, a Node.js app has its dependencies installed in the node_modules directory in the project root.
So, after running npm install (or npm install --production), you should be able to zip up the project directory and that should be all you need.
If any of your dependencies in node_modules are native addons, then you will not be able to install them on a different architecture or OS. If there are native addons, you will also want to make sure your target machine has the same version of node installed as the machine where you created the zip file. (It's a good idea anyway, if you can, to make sure the node version on the target machine is the same as the source machine.)
One obvious requirement of the target host if you do as I describe above is that node is already installed there. Not sure if that's OK for your use case or not, but sounds like it probably is?
Thank you, all of you for your help.
I got the solution for my question.
I am using npm pack to pack the nodejs app.
To pack nodejs app with some dependencies like morgan, express we need to use npm bundle it helps to include the other module required for node js app.
With this, we don't need to perform npm install.
We just have to install bundle and then include bundleDependencies field including the name of required module in package.json.
And then perform then run the command npm pack. It will create a tar file just copy this file in other folder and uncompress it and run the server starting file.
The place where you are going to run the nodejs file, there nodejs app should be installed
I think you might be looking for this: https://github.com/nexe/nexe
Nexe is a command-line utility that compiles your Node.js application into a single executable file.
What I'm trying to do is download packages with all their dependencies, in order to transfer them to another computer that does not have an internet connection and install it there.
So the scenario would be:
Download package (to zip/tarball/whatever file) without installing it.
Included in that downloaded file would be all of its dependencies (correct versions, and it's dependencies' dependencies).
Transfer file to other computer.
Run npm install to file location (optional -g important).
Package is installed with dependencies.
Happy camper.
I feel like there has to be a npm command to download and pack (create) files this way.
I've tried looking for a solution for this to no avail.
This is my first time using node so I'm affraid I'm not researching it correctly because lack of knowledge of the node/npm lingo.
I just used this gist by Jack Gill to do exactly what you describe -- bundle up a package, with all its dependencies. Basically what the script does is re-write a module's package.json file to move all its dependencies to bundleDependencies, then pack the whole thing. Upload the resulting tarball to your server, then npm install it. Works a treat.
Download the package to a machine with internet.
Make sure your app package has a package.json file at its root with all of your dependencies listed in it. You can make npm save your dependencies in package.json by doing npm install dependency-name --save. The --save flag will cause npm to write the dependency to your app's package.json file if it has one. If it doesn't have on then it will do nothing. You can also instruct npm to create a package.json file for your app if you need to by simply running npm init from in your app's directory.
Run npm install from inside the app's directory. This will create the node_modules directory and install all the dependencies listed in the app's package.json file.
Zip up the directory now that it has a node_modules directory in it with all your dependencies installed. Transfer the zip archive to another machine.
Simply unpack the archive in its final destination and you're done. The app is now where it needs to be and the dependencies are already installed.
Now just run the application with node app.js, replacing "app.js" with whatever the name of the app's main entry point file is.
You can just use the npm pack command.
So for example:
npm pack lodash
This command will download the npm package and create a file lodash-4.17.4.tgz.
Installing this can be done with:
npm install ../../my-location/lodash-4.17.4.tgz
More details here:
https://docs.npmjs.com/cli/v8/commands/npm-pack
Simply run npm install in the package directory and archive the entirety of it.
Assuming there are no non-npm requirements you need to meet and both machines are running the same version of node, nothing more needs to be done. All of the downloaded dependencies will be installed inside the ./node_modules. But it is a generally good idea to archive the entire package, as the developer might have implemented some additional setup routines.
you can download package with all its dependencies with its dependents using single command. Kindly refer this link npm-package-downloader
I'm evaluating JHipster; it looks great for rapid development!
Maybe a novice question: I see that the generated .gitignore ignores certain things, e.g.
/node/**
/node_modules/**
So, if I check in the generated project to a repository, and then some other developer in my team checks it out in his environment, the project would not work in his environment. Would it?
Was curious to know how to handle this. Thanks.
Since your git repo won't track node packages, others using your git repo will need install node.js, then run npm install to download all the node packages.
It's similar to them having to have java and maven installed on their environment.
Update: A developer will run 'git clone '. The source (not including node or bower) will be on their workstation. Once they've installed node.js, they'll run 'npm install' and the node directories will be created automatically for your project by downloading them from the Internet. That way you don't need to keep all your node libraries in your own git repository ...just their package name and version in the package.json file (similar to maven dependencies in pom.xml).
No one should commit the node_modules or bower_components to git, what you would do is share the project like you share the maven projects.
Write in the read me what needs to be done to get them ready, for example the installation of yo, bower, grunt or gulp and generator-jhipster.
What is very nice about liquibase, each developer can have his own version of the database, and every commit has its own database version.
What we our team does, if a developer adds something to node js package.json then we mention it in the comment: npm install needed and the same applies for bower.
That way you keep all your environments clean, and if you would like to install continuous integration like "Jenkins or Teamcity" then you make sure Jenkins is building rebuilding the whole project.
I've been looking around for a Java maven equivalency for NodeJS but can't really seem to find one so I'm posting this question to see whether there're a combination of tools/framework I can use to build and deploy Node. The specific tasks I'm looking for is:
Being able to grab dependent modules for a checked out code NodeJS project (for ex. Express or stuff like that)
Set up a private repository for NodeJS modules for in-house projects
Package with dependencies and make releases of Node projects to a repository (sorta like war)
Deploy a release to a remote box and fire up Node
Any help would be greatly appreciated!!!
Npm does most of that for you.
Dependency handling:
Create a package.json for your project (see required contents or use npm init)
Commit it along your project files, this will be your dependency tracking
npm install will sort out and download all dependencies
Deploying:
Upload/push your files to the server
Either send the node_modules folder along or run npm install on the server
To use your private libraries you'll need to either upload the modules folder or publish them (see below)
Private/local libraries:
Create the library anywhere you want (e.g. ~/Projects/mylib)
go to the mylib folder and run npm link
go to the project's folder and run npm install mylib
Now your local library is symlinked into your project's node_modules
To set up a private repository for your modules, follow these instructions
