Modify (patch) meteor packages in a clean way - Meteor - javascript

I am currently using the accounts-ui-bootstrap-3-blaze package in my Meteor application and I want to modify the login_buttons_dropdown.html file to just add an additional button in the drop down.
How can I patch this package in a 'clean' way?
I already downloaded the package and embedded it manually via the smart.json file, but then I was not able to perform an automatic update via mrt.
Any help would be greatly appreciated.

If it's only for the purposes of a single project then the easiest way would be not to use mrt at all, but put the package source code to the packages directory manually. You will also have to update the .meteor/packages file by yourself. One advantage of this solutions is that any updates to the package source code will be automatically detected by Meteor, so you can take advantage of the hot-code-push feature. This is particularly convenient while in the development process.
If you're planning to re-use your patches in other projects, then I would recommend forking the original repository. It should be quite easy as it will be probably hosted on github. You don't need to publish a package on the atmosphere to be able to install it with mrt command. The only thing you need to do is tell the meteorite to look for this particular package in your custom github repository, so:
"accounts-ui-bootstrap-3-blaze": {
"git": "https://github.com/yourUsername/accounts-ui-bootstrap-3-blaze.git"
}
in your smart.json and you are good to go.

Why some libraries in simple vanilla Js require NPM?

I am pretty new to js. And I am looking to learn js. Recently I came across one library called bounce.js which is animation library. Which require NPM to install but why? I am dont want to use NPM (or any packet Manager) they havent provided min.js file to direct import in scrpit tag?? Why??. Similarly for Tailwind it require NPM. And as NPM require it means I need vercel to deploy and all stuff.
2) As I use django I dont know how to install NPM modules in my templates.
Please help me clear out from this mess.
When all I can find is NPM based installation guides I like to search the library name followed by CDN which typically brings up some minified results. In your case I tried searching for bounce.js CDN which brought up lots of results including this one:
https://cdnjs.com/libraries/bounce.js/0.8.2
which points to
https://cdnjs.cloudflare.com/ajax/libs/bounce.js/0.8.2/bounce.min.js
You should be able to do some searching and find the CDN you wish to use. If you want the source JS to serve from your own server you can visit the .js link and right click and download (or copy and paste into your own file).
One of the advantages of using npm over a direct download is facilitating the integration into your workflow.
For instance, if you use a module bundler, the bundler will generate an "optimised", minified version for you: Getting rid of unused code for you (=> Tree shaking) reducing the size of your resulting code, solving some import issues, and more
NPM will also help you keep track of your imported library. You know if you use an up-to-date or outdated version. It will also inform you about
Eventual securities issues. And much more.
There are many, many advantages of using npm over direct download.

How to use JavaScript NuGet libraries in ASP.Net Core project correctly on the example MathJax?

I installed MathJax library for my site on ASP.Net Core from Package Manager.
I have seen 'MathJax (2.7.0)' in NuGet Dependencies:
Image of My Dependencies
But is it all. When I see wwwroot\lib directory in my project I don't see 'MathJax' folder or something similar in it:
Image of My fron-end lib
But when I need use MathJax I need write something similar in my html-page:
<script type="text/javascript" async src="~lib/MathJax/MathJax.js?config=TeX-AMS_HTML-full"></script>
I can't copy NuGet library directly in wwwroot\lib, because I don't want to add my git repository a lot of files external project (> 36 Mb, > 1500 files). Besides, why use NuGet then?
Also, I can't add existing items of MathJax NuGet library manually (menu Add -> Existing Item...), because they are a lot and the absolute path will not correctly on another PC.
How I can get correctly link on MathJax library in NuGet package?
The JavaScript/CSS library NuGet packages are not for Core. They're for MVC. ASP.NET Core has a completely different approach to static files and client-side libraries than ASP.NET MVC did.
For an ASP.NET Core site, you need to use either LibMan or npm to get your client-side libraries. LibMan is easier, but also very naive and limited. In particular, it only supports libraries that are on cdnjs. While there's a lot of coverage there, it's not comprehensive, and there's some libraries that just are available. I'm not sure whether your particular library is or not.
However, given that you'll almost inevitably end up needing something you can't get through LibMan, and and then you'll be forced to use npm anyways, you might as well just use npm and get used to it. There's more of a learning curve because you also need to create build tasks with something like Webpack, Gulp, Grunt, etc. The npm packages go into a node_modules folder, which should not be served directly. At the very least, you'll need to use Webpack, Gulp, etc. to copy the dist/build of the npm package (i.e. the actual JS/CSS files that you'll be referencing) into your wwwroot/lib directory. There's lots of guides online for how to set this up. Just do some research.
In the VS2019, go to the wwwroot/lib directory, right click and select Add -> Client-Side Library. then include your file.
Go to the web project, right click and go the manage client scripts, then search your library and instal.

How do I create an npm package from an existing one?

I'm relatively new to node and the npm package system. For my redux/react web application, I currently use the photoswipe package in combination with react-photoswipe. Now I wanted to add some extra functionality to the photoswipe package, so I went into the photoswipe folder in the npm-modules folder, made the required changes and ran npm build in there.
This works, but the changes will of course be lost as soon as for whatever reason the node_modules-folder gets deleted and recreated, or if I upgrade the photoswipe package.
What is the correct workflow in this case? Can I somehow clone the existing package, change it, then store it in something like a local repository that npm recognizes? Thanks alot for clarification!
The answer depends on the license of the photoswipe package. If it is open source then I would highly recommend that you open a pull request with your changes so that everyone benefits from your feature :)
That being said, you can always clone the package, make your changes and reference the photoswipe package from your github repo. For e.g.: npm install github:alex-cory/fasthacks

Can you use a npm package without using NodeJS

I found a library on github that I would like to use but the download instructions only mention using npm but I am not using a NodeJS project (just a basic html,css,javascript front-end with no back-end server). Am I still able to use that library or is it a lost cause? Is there another way to download it without using npm?
Is there another way to download it without using npm?
If it's on github, then you can checkout or fork the repository as you can with any other git repo.
Am I still able to use that library or is it a lost cause?
Whether or not the library will work without Node will depend on the library.
If it presents itself as a Node module, then you'll probably have to modify it (or find a compatible module loader for browser-side JS).
If it depends on NodeJS features (such as the filesystem API) then you'll be out of luck (unless, for example, you polyfill them to work across HTTP)
If you use a build tool such as browserify, or webpack, you can author scripts that require node modules and the build tool will generate a script that includes all the necessary dependencies (assuming that the necessary dependencies are compatible with client-side JavaScript environments).
Downloading dependencies would still be done via npm, but only for local development. Your server would only need the generated script.
Alternatively, if the script is on github or any other repo online you may be able to download it directly. Many modules are published using UMD, which would allow you to use the script using various inclusion methods.

In the past, I made some websites with notepad for example, so we must create a folder TREE and put into it a .htm file, and some folderS with stuff like Javascript, css ...
Maybe I don't understand what NPM really brings, because It seems to do the same thing but automated it ... is it just that ?
For example, why not just unpack a frameworks (e.g. Bootstrap or Kube) without use of NPM and so have folders ready to use ?
Help me to understand please because I'm near the crazy state with all this stuff ...
npm is a package manager for Node.js with hundreds of thousands of packages. Although it does create some of your directory structure/organization, this is not the main purpose.
The main goal, as you touched upon, is automated dependency and package management. This means that you can specify all of your project's dependencies inside your package.json file, then any time you (or anyone else) needs to get started with your project they can just run npm install and immediately have all of the dependencies installed. On top of this, it is also possible to specify what versions your project depends upon to prevent updates from breaking your project.
It is definitely possible to manually download your libraries, copy them into the correct directories, and use them that way. However, as your project (and list of dependencies) grows, this will quickly become time-consuming and messy. It also makes collaborating and sharing your project that much more difficult.
Hopefully this makes it more clear what the purpose of npm is. As a Javascript developer (both client-side and server-side), npm is an indispensable tool in my workflow.
NPM basically is the package manager for node. It helps with installing various packages and resolving their various dependencies. It greatly helps with your Node development.
