Sooner or later, you will face with situation when you want/need to make some changes in the library. Then the most important tool for you it's the npm link.

Please, notice that it will not work if you link the library just from the root of the repo. It happens due to the location of sources ./src. You need to pack the library first, make pack and then link it from the ./dist directory.

Yeah, it's not such a comfortable solution for development. But it can be fixed by writing a small script similar to making a pack but by linking every file and directory from ./src to the same directory and linking then from it. Notice that you need to link a package.json and a package-lock.json as well.

So step by step:

make pack;
cd dist;
npm link;

cd $project_dir/js # Navigate to JS directory of the project where you want to link the library
npm link foris

And that's it ;)
