How to import all files in a directory into build?

[aiktb]

I need the *.dat.gz files in the assets/dict directory, but they are not automatically packaged into assets, how can I do this?

import kuromoji from '@sglkc/kuromoji'

import type { PlasmoMessaging } from '@plasmohq/messaging'

import type { MojiToken } from '~contents/kanjiTokenizer'

const handler: PlasmoMessaging.MessageHandler<
  { text: string },
  { message: MojiToken[] }
> = async (req, res) => {
  const tokenizer = kuromoji.builder({ dicPath: 'assets/dict' })
  tokenizer.build((_err, tokenizer) => {
    const message: MojiToken[] = tokenizer.tokenize(req.body!.text)
    res.send({ message })
  })
}

export default handler

package.json

"manifest": {
    "web_accessible_resources": [
      {
        "resources": [
          "assets/dict/*.dat.gz"
        ],
        "matches": [
          "https://*/*"
        ]
      }
    ]
  }

src/background/messages/tokenizer.ts

const tokenizer = kuromoji.builder({ dicPath: '../../assets/dict' })

This will solve the problem.
But there are a few things to be aware of:

1. The behavior of chrome.runtime.getURL(path) is very strange. I have to write const path = '../assets/dict' to use fetch normally.
2. The normal operation of '../../assets/dict' depends on the directory structure generated by build to be static/background/index.js. If this is src/background/index.ts, obviously It will be broken.
3. I tried to reference resources in node_modules and found that it does not support the use of wildcard character '*'. Why?

I now realise that Service Worker does not have access to "web_accessible_resources"!
fetch(chrome.runtime.getURL('assets/dicts/')) doesn't make any sense in Service Worker.
fetch(chrome.runtime.getURL('../assets/dicts/')) is just accessing the root path of the extension file, not web_accessible_resources.
