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 npm link.

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

Yeah it's not such comfortable solution for development. But it can fixed by writing small script similar as make pack but with linking every file and directory from ./src to the some directory and linking then from it. Notice that you need to link package.json and 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 ;)
