如何指示webpack观察NPM链接依赖项（包）中的更改

Question

I'm trying to figure out how to get webpack to watch an NPM linked dependency. I've tried to add an explicit entry pointing into the package, and I've tried to both explicitly included it and also not excluding /node_modules/ (which is quite common).

The scenario I want to achieve is as follows: I want to separate out parts of my react-based applications into component libraries (NPM packages).

Both the main package and the dependencies are written in ES6, so I've created a small gulp script that watches for changes in the dependent project, and transpiles its source (src/) to lib.

I've used npm link to wire in the dependent package so that I don't need to pack/publish/reinstall it every time I make a change.

When I make changes to the dependent package, the gulp tasks transpiles the code OK.

It is in the last part I am struggling; getting webpack watch to trigger a re-bundling when the dependency is refreshed by the forementioneds gulp task.

Make sure you transpiler script doesn't delete your old /lib dir, but overwrites files instead.

I had a similar problem with Webpack dev server not seeing changes because I was removing the /lib dir before every transpile.
