How to check if nodejs process failed due to a timeout?-CodePudding

I spawn a synchronous process like this:

child = spawnSync('somecommand', { stdio: 'inherit', cwd: someDir, timeout: 30000});

Is there a reliable way to check if the child process failed due to the timeout option or some other error?

CodePudding user response：

You should check for the log of node which is running down there somewhere. You must be running this with a cli so you can see the log there. Or you can look for where the log is saved. Everything, specially the errors are noted there.

If anyone runs into the same problem, there is a simple way to retrieve the timeout error code at run-time:

 if (child.error && child.error.code === "ETIMEDOUT") {
   console.log("child timed out");
 }
