Create and use your own npm packages in multiple projects

In the world of software development, efficiency and scalability are not just desirable, they are a must. As developers, we are constantly looking for tools and strategies to optimize our workflow and create robust and maintainable applications.

In the web development ecosystem, one of these strategies, often underestimated, is the creation and use of own NPM packages.

My path as a full-stack developer has exposed me to a wide range of projects. Throughout this journey, I have learned that code reuse is not simply a "good practice", but a strategic necessity. On countless occasions, I found myself repeating the same logic and functions in different projects, which led me to the idea: the need to centralize and reuse my own code.

A paradigmatic case was my experience with the "xlsx" package. While it is a powerful tool for handling Excel files, its sometimes complex syntax and the need for additional code to adapt it to my needs made me rethink my approach. I then decided to encapsulate the specific logic I needed in an NPM package of my own, thus extending the functionality of "xlsx" and creating a tailor-made tool for my projects.

Some of the benefits of creating your own NPM packages are:

• Cleaner and more readable code: Abstracting complex logic into a standalone package made my code more concise and easier to understand.

• Accelerated development: Reusing my own code through an NPM package significantly accelerated the development of new features.

• Simplified maintenance: Updates or fixes were centralized in the package, making it easier to update all projects that used it.

Creating and publishing my own NPM package not only streamlined my workflow, but also empowered me as a developer. It allowed me to take control of my development ecosystem and create custom solutions for recurring challenges.

I used a tutorial that I can't find at the moment, but I saw this one and I think it's pretty accurate (it's in Spanish):
