--snapshot-blob=path

与 --build-snapshot 一起使用时,--snapshot-blob 指定写入生成的快照 blob 的路径。如果不指定,生成的 blob 会写入当前工作目录下的 snapshot.blob。

\When used with --build-snapshot, --snapshot-blob specifies the path where the generated snapshot blob is written to. If not specified, the generated blob is written to snapshot.blob in the current working directory.

在没有 --build-snapshot 的情况下使用时,--snapshot-blob 指定用于恢复应用状态的 blob 的路径。

\When used without --build-snapshot, --snapshot-blob specifies the path to the blob that is used to restore the application state.

加载快照时,Node.js 检查:

\When loading a snapshot, Node.js checks that:

1. 正在运行的 Node.js 二进制文件的版本、体系结构和平台与生成快照的二进制文件完全相同。

   \The version, architecture, and platform of the running Node.js binary are exactly the same as that of the binary that generates the snapshot.

2. V8 标志和 CPU 功能与生成快照的二进制文件兼容。

   \The V8 flags and CPU features are compatible with that of the binary that generates the snapshot.

如果它们不匹配,Node.js 拒绝加载快照并以状态码 1 退出。

\If they don't match, Node.js refuses to load the snapshot and exits with status code 1.
