Node.js child_process
extensions
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 processstdout
- 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 writtenstdout
stderrBuffer
- Buffer that exposes so far writtenstderrr
stdBuffer
- Buffer that exposes so far writtenstd
Promise resolves with object with three properties:
code
- Exit code of a child processignal
- Signal that terminated the processstdoutBuffer
- Buffer containing gatheredstdout
contentstderrBuffer
- Buffer containing gatheredstderr
contentstdBuffer
- Buffer containing gatheredstderr
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.
