Vite 通過特殊的 import.meta.hot 對象暴露手動(dòng) HMR API。

interface ImportMeta {
  readonly hot?: {
    readonly data: any

    accept(): void
    accept(cb: (mod: any) => void): void
    accept(dep: string, cb: (mod: any) => void): void
    accept(deps: string[], cb: (mods: any[]) => void): void

    prune(cb: () => void): void
    dispose(cb: (data: any) => void): void
    decline(): void
    invalidate(): void

    on(event: string, cb: (...args: any[]) => void): void
  }
}
