npm installs a multitude of dependencies

Question

npm installs a multitude of dependencies

Recently, I purchased an HTML template that includes various plugins stored in a directory named bower_components, along with a package.js file. While trying to add a new package that caught my interest, I opted to utilize npm for the task.

Upon entering the command:

npc install pnotify

The creation of a node_modules directory ensued, housing approximately 900 subdirectories containing other packages.

I found myself questioning the purpose of these installations and why they were necessary alongside my chosen package. After conducting some research, it became clear that they served a function, but must all these additional packages be included when delivering my template for production?

This question brings up an interesting point that I'd like to address.

The V8 engine, Node Modules (dependencies) and how they are "required":

Node.js is built on the V8 engine, which is primarily written in C++. This means that when you require a dependency in Node.js, you're essentially calling code/functions from a C++ program or JavaScript library.

Many functions in libraries remain unused:

Consider the express-validator module, for example. While it offers a plethora of functions, most users only utilize a fraction of them. Yet, the entire module including all functions gets downloaded, unnecessarily taking up space.

Node dependencies as Interpreted Languages:

Think of node dependencies as branches of a tree - each new branch adding convenience and efficiency to save time and ultimately make things faster. Instead of reinventing the wheel by creating entirely new dependencies, developers often build upon existing ones to streamline the process.

Challenges with cascading NPM dependencies:

Authors sometimes unintentionally download additional dependencies while utilizing specific features, resulting in wasted space. Large projects with numerous dependencies can quickly accumulate unnecessary bulk.

Possible solutions:

Option 1: Experts could manually trim down downloaded packages by removing unused functions within module directories without altering the overall structure.

Option 2: Creating personalized dependencies in C++ or JavaScript can minimize space usage but requires significant time investment.

Option 3: Utilizing tools like WebPack can help optimize package management.

In conclusion:

While it may be challenging to avoid downloading all node packages, options exist to streamline your dependencies and mitigate unnecessary bloat. Consider these solutions based on your specific needs and project requirements.

Although this question is quite old, I recently found myself in a similar situation as RA described.

I was working with the node.js framework using vscode, and when I attempted to start npm using npm init -y, it generated numerous dependencies. Specifically, an issue arose due to the ESlint extension I had added to vscode before running npm init -y.

I uninstalled ESlint
Restarted vscode to finalize the uninstallation
Deleted the previously generated package.json and node-modules folder
Ran npm init -y again

Following these steps resolved my issue of starting with excessive dependencies.

Is it really necessary to include around 900 package dependencies in your project just to add a template? The decision is ultimately yours to make!

The weight of a template does not necessarily impact the node.js ecosystem or its primary package system npm.

In the javascript community, there is a trend towards creating small, specialized modules for individual tasks. While this may not be a negative approach, it can lead to a proliferation of dependencies in your project.

With the current affordability of hard drive memory, efficiency and size optimization are no longer top concerns for many developers.

Ultimately, the choices you make will depend on your individual preferences and priorities.

Why go through the trouble of delivering numerous heavy packages for a small project?

There really is no point.

If you plan on sharing it with other developers, simply ignore the node_modules or bower_components directories (or remove them from the shared package). Developers can easily install the dependencies again when needed ;)

If your project involves basic things like HTML templates, node may just be there to simplify your life as a developer by offering live reload, compiling/transpiling features for languages like TypeScript, Babel, SCSS, SASS, LESS, CoffeeScript... (the list goes on ;P), and so on.

In this scenario, dependencies are likely to only be dev_dependencies and not necessary in a production environment ;)

Many packages also come with separate production and dev dependencies, so you only need to install production dependencies...

npm install --only=prod

If your project requires many libraries in production and you want to avoid unnecessary bloat, you could manually include the CSS/JS files that your project needs (but this can be quite a tedious task).

Update

Production vs Default Installation

Most projects have different dev and production dependencies.

Dev dependencies might include compilers for SASS, TypeScript, etc., minifiers for code (uglifiers), tools like live reload, and so on.

On the other hand, the production version will exclude those elements, reducing the size of the node_modules directory.

** No node_modules **

In certain HTML template projects, there may be no need for any node_modules in production, so skipping an npm install is possible.

No Access to node_modules

Alternatively, in some cases where the server handling everything resides within the node_modules itself, access to these files may be blocked (as they are not meant to be accessed from the frontend).

What are these mysterious additions to my package? How did they end up here?

Dependencies play a crucial role in enabling code reusability and modularity.

Must I really include numerous unnecessary packages when deploying my template?

It's important not to overlook the benefits of modularity. By organizing your requires and removing redundant code, you ensure that updates and patches to dependencies are seamlessly integrated into your project. Think of it as a form of compilation; after all, at its core, that's exactly what it is.

If you have permission to distribute all of your dependencies in this optimized, compiled format, you'll be pleased to know that a JavaScript-to-JavaScript compiler handles these optimizations. Take the Closure Compiler, for example, which offers features like advanced compilation, including dead code removal and function inlining. It certainly shows promise!

On the flip side, there is an added challenge when it comes to justifying the licensing of numerous npm modules. Managing hundreds of dependencies can make this task even more laborious.
