I found that the bug was caused by the Vite cache. I've tried if remove them and that can fixes the issue. So i think that when it using <script setup> and the templates and scripts both has changed, it needs to re-cache.

If that solution is okay, I can try to pr it. :smile:

@glitchboyl the issue is only show while using

[glitchboyl]

@we125182 Yeah, thank you for your complement. While using <script setup>, it didn't generate the cache but generate resolved everytime, I need to dig in and figure it out why.

@sapphi-red @patak-dev it is similar with issue #6568 and PR #4563. the bug was caused by this line. using <script setup lang="tsx"> in sfc file, while template code changed and affectedModules.has(mainModule) === false it will use prevDescriptor. because of this, script code changing was ignored.

// packages/plugin-vue/src/handleHotUpdate.ts
export async function handleHotUpdate(
  { file, modules, read, server }: HmrContext,
  options: ResolvedOptions
): Promise<ModuleNode[] | void> {
  ...
  const affectedModules = new Set<ModuleNode | undefined>()
  const mainModule = modules.find(
    (m) => !/type=/.test(m.url) || /type=script/.test(m.url)
  )
  const templateModule = modules.find((m) => /type=template/.test(m.url))

  if (hasScriptChanged(prevDescriptor, descriptor)) {
    let scriptModule: ModuleNode | undefined // TODO: this line should move out of block
    if (
      (descriptor.scriptSetup?.lang && !descriptor.scriptSetup.src) ||
      (descriptor.script?.lang && !descriptor.script.src)
    ) {
      const scriptModuleRE = new RegExp(
        `type=script.*&lang\.${
          descriptor.scriptSetup?.lang || descriptor.script?.lang
        }$`
      )
      scriptModule = modules.find((m) => scriptModuleRE.test(m.url))
    }
    affectedModules.add(scriptModule || mainModule)
  }

  if (!isEqualBlock(descriptor.template, prevDescriptor.template)) {
    // when a <script setup> component's template changes, it will need correct
    // binding metadata. However, when reloading the template alone the binding
    // metadata will not be available since the script part isn't loaded.
    // in this case, reuse the compiled script from previous descriptor.
    if (mainModule && !affectedModules.has(mainModule)) { // TODO: here should add condition: !affectedModules.has(scriptModule)
      setResolvedScript(
        descriptor,
        getResolvedScript(prevDescriptor, false)!,
        false
      )
    }
    affectedModules.add(templateModule)
    needRerender = true
  }
