webpack externals with wildcard

Question

How can I instruct webpack to exlude all d3-modules?

// does not work
externals: {
        "d3-*": "d3"
    }

So if app imports d3-submodule, then webpack should not include this submodule because I have already included d3.js.

Answer 1

You should be able to use regular expressions (see https://webpack.js.org/configuration/externals/#regex).

// This might work
externals: /^d3-.*/
