How to develop npm module locally

Lets say im working on an app, MyApp, and I want to build an NPM module for it, MyModule. Right now I can think of two ways to develop it:

Makes changes -> save -> npm install /path/to/module in MyApp

Same as 1, except run npm install /path/to/module then editing it directly in node_modules then copying the changes over.

What I'd like is an easier workflow. One where I can simply save the file, refresh the page, and my changes are there. Is that possible? For example, I know in Gemfiles I can just link to another directory as the path. Pretty sure I can't do that with npm tho.

You're looking for the npm link command, which is a two steps process:

Run npm link from your MyModule directory: this will create a global package symlinked to the MyModule directory

Run npm link MyModule from your MyApp directory: this will create a MyModule folder in node_modules, symlinked to the global symlink (and thus to the real location of MyModule).
