软件包：node-tmp（0.2.1+dfsg-1）
Temporary file and directory creator for Node.js
The main difference between node-temp and node-tmp is that node-tmp more aggressively checks for the existence of the newly created temporary file and creates the new file with O_EXCL instead of simple O_CREAT | O_RDRW, so it is safer.
The API is slightly different as well, Tmp does not yet provide synchronous calls and all the parameters are optional.
Tmp uses crypto for determining random file names, or, when using templates, a six letter random identifier. And just in case that you do not have that much entropy left on your system, Tmp will fall back to pseudo random numbers.
You can set whether you want to remove the temporary file on process exit or not, and the destination directory can also be set.
Node.js is an event-based server-side JavaScript engine.
