Install Nestjs peer dependencies for development - npm

I download source code of (Nestjs)[https://github.com/nestjs/nest] framework and try to install its dependencies by running npm ci and after that lerna bootstrap. It works fine some how. But when I run tests it fails on nest-application.spec.ts file arguing it has #nestjs/microservices dependencies which is not resolved. As I see in core package node_modules folder there is only a symlink to common package. Although in core's package.json file #nestjs/microservices is marked as peer dependencies but lerna does not put it's symlink in node_modules folder. I also though that was an issue and opened a pull request https://github.com/nestjs/nest/pull/10165 which added #nestjs/microservices as devDependencies in package.json file which got rejected by kamil. If thats not a issue how can I install peer dependencies by lerna or any other method? How do themselves develop the project? Of course I can manually symlink the folder but I'm sure kamil is not doing it this way :)

Automatically downloading npm packages listed in package.json file

I'm working on creating a local repository that will contain all packages I use in my project, so I can have those packages installed on a machine that does not have access to the internet. I think of the repository that I could clone on the machine and run yarn install to have all the packages available in the project from the local repository. How can I do that? Similar question was asked here Using npm how can I download a package as a zip with all of its dependencies included in the package
There's not enough information in your question to fully understand your situation, but if you commit your node_modules directory to the repository, the modules will be there without the user having to run npm or yarn to install them. This assumes the user will run code from the repo workspace and that there aren't any modules that require a compilation step or other build step that may be platform-specific. But if they're all plain ol' JavaScript modules, you should be fine.
If you want to have all the modules as a separate repo rather than checking in node_modules, I can offhand think of two ways this might work.
Have the packages repo be a check-in of a fully installed node_modules directory. Then make that repo a Git submodule of the main repo that gets cloned as node_modules in the main repo.
Use npm pack to create .tgz files for each package you need. Store those files in the packages repo. Clone that repo into a known path on your target machine. Have the main repo install via path names. For example, if you run npm install /var/packages/foo-1.0.0.tgz, it will add a line to your package.json that might look something like this: "foo": "file:../../../var/packages/foo-1.0.0.tgz". In that case, npm install will install from that path rather than over the network.

React-Native dependencies integration issue

I'm beginner in react-native Sorry in advance if found issues in question asking.
I cloned a repository from remote server where now i've empty node_modules directory. I've "package.json" file with all dependencies list while when I run "npm install" I didn't get dependencies in node_modules directory and got number of warnings on terminal related to different files as you can see here.
delete node_modules folder.
Then try to do npm install first. it ll added node modules folder.
after that try to install dependancies..you can find necessary dependancies from json file.
ex:- npm install --save depencencyname#versionnumber
for some modules you have to link them before it use..
using react-native link dependancyname

Use of creating a package.json file in our Node project

Why do we create a package.json file using npm init and what is its use while uploading our project on git?
Your package.json is the core of npm. In this file all of your dependencies and node packages are outlined. It's important to upload to you git repository so that anyone cloning your project will have the same dependencies and packages on the same version as the project was developed in. In addition, being able to startup a project with npm start and npm install makes everyone's life easier.

How to install npm own local packages?

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.

npm 5 install folder without using symlink

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.
