Bundle local NPM dependencies and publish - npm

I have a project comprised of:
module1/
module2/ (depends on module1)
mainmodule/ (depends on module2)
Is is possible to publish mainmodule without publishing module1 and module2?
I.e. to somehow bundle the local dependencies inside of mainmodule?

Are you importing the dependency module using import or require? If yes, yes you can create a unique bundle from your mainmodule using a bundler like webpack.
Inside your mainmodule, you just need a package.json file and Webpack installed locally or globally. After that just run this command
webpack mainmodule.js -o bundle.js
and Webpack will bundle all the modules together is just one module.

How do I use a local plugin with ParcelJS

I use ParcelJS to bundle my JavaScript code. I want to modify an existing plugin (say the Elm plugin) to convert some special files on the fly with our own proprietary transpiler to JavaScript.
Therefor I cannot install the plugin from teh npmjs repo via Yarn into the node_modules folder. I have the relevant plugin files (asset.js, index.js, package.json) in a local directory myplugin. How do I tell ParcelJS to use them?
If you have your plugin with a package.json in the directory myplugin you can add add it (as a dev dependency) with the following command:
yarn add ./myplugin --dev
Yarn will copy the plugin to the node_modules folder. When you have changed stuff in your plugin folder increase the version number in the plugin's package.json and run yarn upgrade.

Using Node Modules in Simple Project

I have a very simple web project and I'm using npm init to create the package.json file for the project. My project structure is below:
ProjectFolder
--app /this is the folder for js files
--css
--scss
--lib /this is for files like jQuery
--index.html
When adding a node package, it will create a node_modules folder like this:
ProjectFolder
--node_modules
--app /this is the folder for js files
--css
--scss
--lib /this is for files like jQuery
--index.html
Let's say I add jquery through npm install and make it a dependency. Is it good practice to link to the jquery file in node_modules from my index.html or move the jquery file to my lib folder?
Is there a way to move the jquery file to my lib folder when installing?
I don't want to move the node_modules folder to the server and want to know the best practice.
Your package.json is essentially your link. It contains a list of the packages you are dependent on and their versions. If you install something using npm install it has to be a published npm package on an npm repository somewhere (either public or private). It downloads a zipped version of the npm package and unzips it into node_modules. Anything in there is automatically then available to your app. Hope that helps.

Why does npm run eject look through all my project folders?

I am trying to run an npm run eject on a new project so I can configure Webpack files, but I got this message:
✗ npm run eject
> location#0.1.0 eject /Users/danale/Projects/location
> react-scripts eject
NOTE: Create React App 2 supports TypeScript, Sass, CSS Modules and more without ejecting: https://reactjs.org/blog/2018/10/01/create-react-app-v2.html
? Are you sure you want to eject? This action is permanent. Yes
This git repository has untracked files or uncommitted changes:
Why is it referencing all the project folders? To be clear I am running the above command inside of one project folder I just created with CRA.
I am not in the folder with all my projects, I am in the folder with one newly created project. With that said, why is npm referencing all my other projects?
Before you eject a react project created with create-react-app they give you the following cookie cutter response of:
NOTE: Create React App 2 supports TypeScript, Sass, CSS Modules and more without ejecting: https://reactjs.org/blog/2018/10/01/create-react-app-v2.html
? Are you sure you want to eject? This action is permanent. Yes
This git repository has untracked files or uncommitted changes:
The reason for this is a lot of people want to have a granular level of control of their webpack.config.js file and you've to eject to get access to this file as it's obfuscated away within your react-scripts module. Now the part of the eject warning message saying:
NOTE: Create React App 2 supports TypeScript, Sass, CSS Modules and more without ejecting: https://reactjs.org/blog/2018/10/01/create-react-app-v2.html
Is to inform you that you don't have to eject to take advantage of preprocessors, TypeScript, etc.... They tell you this because create-react-app didn't always support the easy addition of this functionality so people would eject to be able to use preprocessors and TypeScript.
You're correct that in order to use SASS all you have to do is:
Install the node-sass module with a: npm install node-sass
Then just create your .scss files and import your desired .scss file in the component you wish to use the styling at. Alternatively, you could also just have a "main" .scss file whose only job is to import other .scss files relevant for your app. Then import this "main" .scss file within your App.js file.
Now as for this part of the eject warning message:
This git repository has untracked files or uncommitted changes:
You're probably getting this because you've set up a git repository for a parent folder where you ran the create-react-app CLI. Basically, in one of your parent folders where your create-react-app interface is located at is a .git/config that points upstream to one of your remote repositories.
Hopefully that helps!
Between what I read in the documentation suggested in the error message and from tinkering with it, all you have to do is:
npm install node-sass
and then you can start changing css files to scss and creating other scss files for your project. No npm run eject necessary.

Angular 5: Is it possible to link a local npm module?

I have a custom node module, that I can't publish on NPM.
I'd like to use it as any module I have on NPM.
Is it possible without the awful thing of copying the folder into the node_modules?
The answer is: YES, IT's POSSIBLE.
Let's assume your module has a dist folder, with the built source
(for example I run gulp on my src folder and procude the dist folder).
you simply got to run npm pack ./dist in your library.
this will produce a tgz archive with your library named your-library-version
then you can install your module in your project by simply running
npm i path-to/your-library-version.tgz
And you're done.
Let's say my library fodler is C:\ngx-mat-lib
so my tgz will be in this folder, since the dist folder should be a child of ngx-mat-lib.
In my project I'll run
npm i C:/ngx-mat-lib/ngx-mat-lib-0.0.1.tgz
Note: using forward slashes to avoid doubling them

Load modules from other external webpack bundles by their npm module name

Is it possible for a webpack bundle to load modules that are defined by other webpack bundles, without those bundles all having to be globally defined as a library (with libraryTarget and library in webpack config)?
Thus enabling me to reuse the original npm module names as the only reference to different modules.
