npm install child-process-ext

Cross system compliant spawn (backed by cross-spawn).

Works exactly same way as node's spawn with difference that promise is returned that resolves once process exits.

Following properties are exposed on return promise:

• child - child process
• stdout - stdout stream (decorated so it can also be used as promise)
• stderr - stderr stream (decorated so it can also be used as promise)
• std - Merged stdout & stderr stream (decorated so it can also be used as promise)
• stdoutBuffer - Buffer that exposes so far written stdout
• stderrBuffer - Buffer that exposes so far written stderrr
• stdBuffer - Buffer that exposes so far written std

Promise resolves with object with three properties:

• code - Exit code of a child proces
• signal - Signal that terminated the process
• stdoutBuffer - Buffer containing gathered stdout content
• stderrBuffer - Buffer containing gathered stderr content
• stdBuffer - Buffer containing gathered stderr content

If process exits with non zero code, then promise is rejected with an error exposing same properties as above

Whether stdout data should be split by lines. If set to true, then stdout and stderr on promise expose mappers of original stdout and stderr that emit each line with distinct data event

Whether stdin should be closed. Applicable for spawned processes where stdin is set to other than 'inherit' mode, and underlying processes is reading from stdin. Not providing any stdin output, may produce stall if process logic waits for an input. See: get-stdin#13 for more information
