Load an npm package from local directory without copying unnecessary files/folders such as node_modules

Let's imagine I have to develop an npm package, my-package, which needs to be imported and used by my-project.

While developing my-package I need to install and use other packages from npm. At the end of the development of my-package, I bundle all the relevant files in the dist directory. Since I do not want to have all the files in the node_modules folder as part of the package published, I specify in .gitignore (or .npmignore) to exclude node_modules folder. So the final structure of the folder of my-package looks something like

my-package
  dist
    ... // all the code of the package to be distributed
  node_modules
    ... // all the node modules
  src
    ... // all source files
  package.json
  .gitignore

Now I publish my-package on npm repository and then import it in my-project, with the command npm i my-package.

As a result of such import, the structure of the directory hosting my-project is something like

my-project
   ...  // stuff
   node_modules
      my-package
         dist
           ... // all the code of the package to be distributed
         src
           ... // all source files
         package.json

As expected, no node_modules folder is imported under my-package folder.

Since I am the developer of both my-package and my-project, during development I would like to import my-package from the local path with a command which could look like

npm -i ../my-package

If I proceed like this, the result I see is that all the files and folders stored under my-package directory are copied under the node_modules folder of my-project, i.e. .gitignore (or .npmignore) exclusions are not considered. The net result is a structure such as

my-project
   ...  // stuff
   node_modules
      my-package
         dist
           ... // all the code of the package to be distributed
         node_modules
           ... // all stuff imported by my-package
         src
           ... // all source files
         package.json
         ...  // any other file under my-package

Is there a way to install from local path only the relevant files of my-package as it happens if the package is installed from the npm repository?

We had the same problem today. We figure it out by adding to the package.json of the local package

“build”: “yarn run clean && yarn build-components && yarn pack”

And then to the project that is using the local package we added to the dependencies of the package.json

“yourpackage”: “file:../your-tgz.tgz”,

hope it helps

Note: if you are using yarn you might have problems with the cache.
