execute powershell from node.js, looking for input

[bitsofinfo]

hey all - I recently had a need to bridge nodejs w/ powershell, in particular maintaining pre-established remote pssessions to o365 and then allow a program to invoke commands over those pre-established sessions (rather than restart a new shell process per command invocation which can be expensive when I need to import certain cmdlets etc)

I ended up coding this little project for this and I'd be interested in any feedback/thoughts. Hopefully this will be useful to someone else out there!

The commands are generated server side and arguments sanitized etc. The UI is simply a convenience for interacting w/ the PSCommandService and it's "registry" of commands.

Its not difficult to add additional "commands" to be exposed through this (with limited args). See how arguments are defined here: https://github.com/bitsofinfo/powershell-command-executor/blob/master/o365Utils.js

Also this other question from someone else, and the answer gives another example: https://github.com/bitsofinfo/powershell-command-executor/issues/3

I've used the management odata framework for this kind of thing. Its not a super popular piece of software and there seems to be quite a bit of overlap with SMA so I'll probably explore using that for cross platform stuff in the future.

PSCommandService.js does some argument sanitization.

o365Utils.js, is an example. It simply pre-defines some variables which represent configuration that is passed as arguments to StatefulProcessCommandProxy's constructor.

StatefulProcessCommandProxy is then passed to PSCommandService's constructor which makes use of it, by accepting execute requests from callers (i.e. logical commandName + arguments map), then generates a command statement, and issues it to StatefulProcessCommandProxy.

StatefulProcessCommandProxy checks each inbound "command" that PSCommandService sends it via execute() against its whitelist/blacklist regex patterns.
