[Error 3.3.2] Components as variable = "error: __name is not defined" (TSX related)

[arpowers]

Vue version

3.3.2

Steps to reproduce

This issue was introduced with latest Vue, so is a breaking change if intentional.

When importing a component into a TS file and passing to another object:

import MyComponent from './MyComponent.vue'

// later 
const myObject = new SomeClass({el: MyComponent})

Using latest vite/vue this now creates the error:

Any additional comments?

Hoping for a quick resolution to this issue, if there is a debate about this or problem with reproduction, i will create one.

Could you provide a runnable minimal reproduction?

@arpowers temp solution:

var __defProp = Object.defineProperty;
var __name = (target, value) => __defProp(target, 'name', { value, configurable: true });
globalThis.__name = __name;

Add this line in top of vite.config.mts or some of other your code before run vite

@xiaoxiangmoe i've downgraded vue back to 3.2.X ... did you hit the same problem?

@edison1105 yes, i can put one together if this is an isolated issue...

[arpowers]

@xiaoxiangmoe can confirm that the temp solution did patch it

@edison1105 i tried for an hour to recreate this and struck out, gonna take some time to isolate whats causing it (vite vue plugin?)

[arpowers]

@edison1105 @yyx990803 possible to get any suggestions on what might causing this? im struggling to duplicate in a minimal environment... will take me quite a bit of trial and error with packages, vite configs.

[xiaoxiangmoe]

I catch it.

In any vue 3.3.2 project. Add file

// file: run-vite.mts
import * as vite from 'vite'

const root = process.cwd()

async function main() { 
   const viteDevServer = await vite.createServer({
        root,
        logLevel:  'info',
        server: {
            middlewareMode: false,
            hmr: {
                port:6174,
            },
        },
        appType: 'spa',
    })
    
  await viteDevServer.listen()
}

main();

Then run

yarn add tsx
./node_modules/.bin/tsx ./run-vite.mts

Then it throw an error:

[vite] Internal server error: __name is not defined

[xiaoxiangmoe]

@arpowers Do you use tsx or something else to run vite?

[arpowers]

@xiaoxiangmoe yes! Running tsx ... As a nodejs loader anyway

[xiaoxiangmoe]

So, I think it should be a bug of tsx.

[arpowers]

@xiaoxiangmoe good work!

@edison1105 duplicated the issue here: https://github.com/arpowers/vite-example

Is related to tsx

[yyx990803]

Probably related to our addition of vue/jsx-runtime? Although I have no idea how this could cause tsx to compile things differently. Closing as I don't think there's anything actionable on our side (happy to reopen if otherwise)
