Local dependency in package.json

Unraveling the Mystery of Local Dependency in package.json 😎📦

Have you ever found yourself scratching your head over local dependencies in your package.json? 🤔 Fear not! In this blog post, we'll dive into this perplexing topic and help you understand how to tackle common issues and find easy solutions. 💪

Understanding Local Dependencies

Before we embark on our journey, let's define what local dependencies are. Local dependencies in package.json allow you to reference packages that exist on your local machine. This can be useful when you're working on multiple projects simultaneously or when you want to utilize a library that isn't published on npm. 🌐

A Common Problem: Installing Local Dependencies

Let's say you want to install a package from a local directory called ../somelocallib in addition to the regular package dependencies. In your package.json, you might have something like this:

"dependencies": {
  "express": "*",
  "../somelocallib": "*"
}

But here's the catch: when you run npm install, it won't automatically install the dependencies of ../somelocallib. 😱

The Solution: npm link

To solve this, we can use the magical command npm link. It creates a symbolic link between your local package and your project, mimicking a real npm package. 🪄

1. Navigate to the root of your local package (../somelocallib in our case).

2. Run npm link in that directory. This command will create a global link for your local package.

Once you have done this, you can navigate back to your main project directory and run:

npm link somelocallib

This will create a symbolic link to the local package and make it accessible within your project. Now, when you run npm install, it will also install the dependencies of ../somelocallib. 🎉

Calling All Local Dependencies

If you're still having trouble accessing local dependencies or their dependencies, make sure to check the following:

1. Verify that you have specified the correct path in your package.json for the local dependency.

2. Double-check that the dependencies of your local package are correctly defined in its package.json.

3. Ensure that any peer dependencies required by your local package are installed in your main project.

Taking these steps will help ensure a smooth and error-free experience when working with local dependencies. Happy coding! 💻
