remove useless module import

[uinz]

Problem

When --env.NODE_ENV=production is set, require will be treeshaken away, so import { createRequire } from 'module' will no longer be useful.

Expected behavior

There are two improvement suggestions here:

1. When the module is not used, perform treeshaking to remove it.
2. Allow the behavior of create-require to be disabled.

---

The first point can be achieved by configuring the behavior of create-require resolveId to mark the module module as side-effect-free.
