I have 2 projects(packages) in npm, I want to inject package_A as dependency to package_B. In package_A root folder, I run npm install -g, then npm install it to C:\Users\Myuser\AppData\Roaming\npm\node_moduls\package_A folder. Now in packages.json in package_B I add "package_A": "1.0.0" in dependencies. When in package_B root file I run npm install, its failed package_A#1.0.0 not found.
How can I identified npm to its my own local package?
Notes:
We are a team, then I don't want to address package_A explicitly.
We are using nexus repository manager.
I don't want to publish my projects to http://registry.npmjs.org/.
I'm not 100% clear what you have tried. If you are going to use a custom module for another application you are developing, installing globally won't do the trick. You have to publish that module in npm.
Check this link for more info on publishing in npm
If you have completed the steps correctly, and still no good happens, please check your naming of the module in package.json file.
Instead of typing in the name and version number in package.json file and then npm install, try directly installing in the terminal with --save so that it will automatically be added to package.json file with correct spelling.

I have a project that I'm working on for a client where I have two private packages (which I can't get access to npm install) are inside the package.json.
I do however have access to clone the repos for those said packages. If I simply run an npm install I'll get a permission denied error. Same if I run npm link to the packages.
I've been working around this by removing the packages from the package.json then running npm install ../some-package. This works but isn't a great solution because if I wanted to add a new package I'd have to deal with a bit of a mess with the package.json.
Is there a better way than this?
I have tried running npm link ../some-package but I still get access denied. The only way I've managed to complete an install is by removing the packages then installing them from a local dir.
I don't know the details of your situation, but I see at least two potential solutions to explore.
Option 1: Install the package from the repo
I do however have access to clone the repos for those said packages.
You can install from a git repo and package.json will record that git repo as the source of the package rather than the npm registry.
From the docs at https://docs.npmjs.com/cli/v8/commands/npm-install:
npm install :
Installs the package from the hosted git provider, cloning it with git. For a full git remote url, only that URL will be attempted.
Option 2: Install from the local file system with --no-save
If that approach doesn't work for you, you can try npm install --no-save ../some-package as a build step. The --no-save makes it so it doesn't modify package.json.
What happens differently when you go into your package.json and paste a package name in and do npm i vs. doing it the real npm i package-name?
package.json:
"dep": 1.0.0
vs
npm i dep --save
We have a build error and learned can bypass it by pasting. I know it isn't kosher but I really want to know why and what consequences that causes?
npm install dep doesn't add the dependency to the package.json file.
You have to add --save or --save-dev to add it to the package.json file.
Besides that, npm install will always serve you the latest build (in most cases the version tagged as latest (see npm docs)), unless you specify a specific version.
If you want your lock file to update, you have to delete the file before running npm install to generate a lock file with the dependency included (for more info check out this GitHub issue)
In conclussion it shouldn't make much of a difference if you manually add the dependency to package.json file and install it with npm install, unless the latest version of your dependency is broken.
Before publishing my node library, I could use the advice the npm documentation wrote about:
To test a local install, go into some other folder, and then do:
cd ../some-other-folder
npm install ../my-package
Prior to version 5 of npm, I had no problem as it produce what I expected, ie a folder with the output of what I will publish.
However, using npm 5, it now creates a symlink to my local project as described in the npm documentation:
npm install :
Install the package in the directory as a symlink in the current
project. Its dependencies will be installed before it's linked. If
sits inside the root of your project, its dependencies may be
hoisted to the toplevel node_modules as they would for other types of
dependencies.
How can I use the "old" way to install local project? Or is there a new way to check if my library is correct?
Thank you.
Use npm pack + npm install (as suggested by install-local package)
npm pack <path-to-local-package>
npm install <package-version.tgz>
This will effectively copy your local package to node_modules.
Note that this will package only production relevant files (those listed in the files section of your package.json). So, you can install it in a test app under the package own directory. Something like this:
my-package
package.json
test
test-app
package.json
node_modules
my-package
Assuming that test dir is not included in the files in my-package/package.json.
This works the same way with npm 5 and older versions.
I wrote npm-install-offline which allows you to install npm packages from a local repository or folder. By default it copies the folder on install but you can also choose to symlink.
https://www.npmjs.com/package/npm-install-offline
npx npm-install-offline ../some-package
Or
npx npm-install-offline my-npm-package --repo ./my-offline-npm
It also will install the package dependencies which npm does not do with local packages.
I organize my development projects installing globally all the npm packages I need with:
npm -g install [package]
Then I simlink individually the dependencies I need for each project with:
npm link [package]
This way, I have to update manually each package.json file to add the dependency, and when I upgrade the global node_modules I have to go and update all the package.json projects.
For this first issue I tried npm link [package] --save but it doesn't add the dependency to package.json and if I use npm install [package] --save it installs the package locally, thing I don't want.
Is there any way to be able to not have to configure package.json manually and be able to have an updated configuration of package.json from many different projects in a easier way?
Yes you can install npm-check-updates, you can find the install and guide here:
https://www.npmjs.com/package/npm-check-updates
when running 'ncu' on the command-line in your root-folder where your package.json is, it will list the packages that can be updated and by running 'ncu -u' on the command-line it updates all the packages for you.
I tried to maintain package.json with the list of node modules dependencies. when I call npm install it installs the node modules.and generates a folder for it in my app. I call the npm shrinkwrap. But this generates the dependency on the local node module
"dependencies": {
"async": {
"version": "0.2.5",
"from": "async#0.2.5",
"resolved": "https://registry.npmjs.org/async/-/async-0.2.5.tgz"
},
when I upload the app to the appfog server it can install from the npm-shrinkwrap.json. So Ideally I want to remove the node modules folder and just pass the shrinkwrap.json file. But it has this "from". I had in the past generated the shrinkwrap & it didn't have the "from" field in there.
How to generate without "from"/ can I just get a shrinkwrap file from package.json. so my app will be leaner. I can maintain all the node module globally.
Thanks
I'm a bit confused by your question.
Shrinkwrap does not install, package, upload or do anything to your dependencies.
All it does is scan your installed node_modules and record the versions (recursively) into a file. Invoking npm install after that file is defined becomes repeatable, which is a principle of software engineering.
"from" was introduced a few months back. The npm shrinkwrap command seems to set it to the URL from which a module was installed. This is probably for portability. npm install takes a module name, consults a registry (whose URL is configurable as an npm config setting) and installs it. I could take the same package.json and npm-shrinkwrap.json, put them on another machine and theoretically get a different result if that machine's npm config settings point it to a different registry. Therefore, embedding the resolved URL in the shrinkwrap file adds an additional level of repeatability to npm install
See the npm config man page for details of setting the registry parameters.
According to npm issue 3145 on github, the "from" setting is known to cause backwards-compatibility issues with pre-1.2.x npm systems. Upgrading is the only resolution.

I think that you are looking for shrinkpack: https://www.npmjs.com/package/shrinkpack
from the doc:
Shrinkpack complements the npm shrinkwrap command by maintaining a node_shrinkwrap directory in your project, containing the exact same tarballs that npm install downloads from https://registry.npmjs.org.
The rest of the npm install process is exactly the same. The only difference is that no network activity is necessary when installing and building your project. The node_shrinkwrap directory can be ignored in your editor (much like is done with the node_modules directory) but is instead checked into source control.
