Problem with build of webpack and vite in one node instance.

[ThornWalli]

Found that I still get a problem with this plugin when I build webpack and vite in a node instance.

Example a Vitest with two Describes for the respective Builds.

Example: https://github.com/ThornWalli/webpack-sub-style-test

Reinstall the project and then run the task test-1.

One of the two builds runs, both together do not.

await new Promise(resolve => webpack(webpackConfig, resolve));
console.log('webpack build done');

await build(viteConfig)
console.log('vite build done');

This is very strange, I don't think it seems to be the cause of the plugin. But I can't be sure either.
You can write the build code of vite and webpack separately in different js files, and then use node to run to avoid this problem

import { build } from 'vite';
import viteConfig from './vite.config.js';

const startBuild = async () => {
    await build(viteConfig)
    console.log('vite build done');

}
startBuild()

import webpack from 'webpack';
import webpackConfig from './webpack.config.js';

const startBuild = async () => {
    await new Promise(resolve => webpack(webpackConfig, resolve));
    console.log('webpack build done');

}
startBuild()

run:
"test-1": "node test-1.js && node test-2.js"

You can also try using gulp to handle your build process

I will close the issue for now, I have now made separate test files for the different builds. (e.g. webpack.test.js and vitest.test.js)
There is then in each case a single Describe which is executed separately from the other.

Thanks for support 😉

I got the same issue now with Vue 3 cli and Webpack 5

Exactly the same error
if (isComponentUpdateFnIdentifier && parent.type === "VariableDeclarator" && node.type === "Identifier" && node.name === "subTree") {
