watchStaticFile()v4.0.144

监视特定的静态文件的变化，并在文件更改时调用回调函数，从而在你的 Remotion 项目中实现动态更新。

🌐 Watches for changes in a specific static file and invokes a callback function when the file changes, enabling dynamic updates in your Remotion projects.

note

此 API 正从 remotion 包中移出。
建议优先使用此 API，而不是旧的 API。

note

此功能仅在 Remotion Studio 环境中可用。在播放器中，事件永远不会触发。

example.tsx
import { StaticFile, watchStaticFile } from "@remotion/studio";

// Watch for changes in a specific static file

    if (newData) {
      console.log(`File ${newData.name} has been added or modified.`);
    } else {
      console.log("File has been deleted.");
    }
  },
);

// To stop watching for changes, call the cancel function
cancel();
