support importmap

Clear and concise description of the problem

refs: https://nodejs.org/api/packages.html#subpath-imports

I was using

• node.js v18.1.0
• vitest v0.12.4

the package.json imports:

{
  "imports": {
    "#@": "./src/"
  },
}

import { actuator } from '#@/actuator.js'

got the err:

 FAIL  __tests__/actuator.spec.ts [ __tests__/actuator.spec.ts ]
Error: [vite-node] Failed to load #@/actuator.js

Suggested solution

just load the module successfully.

Alternative

n/w
