title: "pip install -e ." equivalent for npm/typescript/react
body: <p>I'm developing a central set of React (Typescript) components that need to be imported from several other projects that are in development as well. When I face this type of situation in Python, I would use <code>pip install -e .</code> from the virtual env of each dependent project. Then I can use <code>from central_package import xyz</code> from wherever.</p>
  
  <p>What is the equivalent procedure for React/Typescript? I have tried <code>npm link</code>, but there seems to be an issue with importing the components: </p>
  
  <p><code>Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.</code></p>
  
  <p>I'm assuming some particular setup is required.</p>
