An error was reported during the process of runing the project: [ERROR]Could not resolve "a"

[Henrytudor-lee]

My program is typescript + three.js + vue3 + vite . My operation is as follows:

// terminal
npm i opencascade.js@beta
npm i vite-plugin-wasm

// vite.config.js
import { defineConfig } from 'vite'
import wasm from 'vite-plugin-wasm'
export default defineConfig({
plugins: [
vue(),
wasm()
],
optimizeDeps: {
include: ['file-loader'],
// exclude: ['a']
},
...
})

// main.ts
import initOpenCascade from 'opencascade.js';
...
initOpenCascade().then((oc : OpenCascadeInstance) => {
this.oc = oc;
});

// terminal
npm run dev

// and error
X [ERROR] Could not resolve "a"

You can mark the path "a" as external to exclude it from the bundle, which will remove this error.

Add '?url' to the reference code. It does work. Look follow:

import openCascade from 'opencascade.js/dist/opencascade.full.js'
import openCascadeWasm from 'opencascade.js/dist/opencascade.full.wasm?url'

// get occ instance
export async function initOcc() {
//@ts-ignore
return await openCascade({
locateFile: () => openCascadeWasm,
})
}
