Re: [nodejs] Node web interface to execute and handle the Perl & Shell backed process.

[Tim Caswell]

Node can easily call other processes and has full control over the stdio streams if desired. (or there are convenience wrappers if you don't need full control)  Look at the child_process APIs.

Hi, I have number of the Perl and shell scripts in server(Linux) to automate the software build process. I want to 

create web interface so that other user can easily run my scripts. 

* Have a webpage, user select the field and press button to launch corresponding process. 

* webpage should show progress, Perl/shell script standard output running in server.

Could some one can suggest me if Node can be used as my fronted to create web interface?

As I am novice so any suggestion from experience people will be appreciated. 

Thanks

the answer is: it depends. Node is a good choice to offer a webinterface to a conglomerate of scripts on os level. in fact this is the big strength of node to handle much i/o. But the question about rewriting has nothing to do with it, it's higher order question:

- are your scripts doing their jobs properly? are they easy to maintain? if yes, then let them be. if no and they need a rewrite, then node might be a good way here too.

- what tasks are this? node is not good at heavy calculations, usually we spin up a new process or call another script for it, i.E. we call imagemagick for resizing images in our service via child_process. 

you have to go through your scripts and answer this questions.

Thanks Tim,

Performance wise do you consider having Perl/shell script in back-end and node as front-end is a good architecture? or is it better to re-write task done by Perl in node. I want to have clear idea about, 

     - Is it better to use node just as a bridge between webpage and Perl/Shell.

Any kind of suggestion would be appreciated.
