fm-exec

What?

Helper to spawn external applications.

• uses child_process.spawn() by default (using the shell is also possible, with exec.shell)
• uses promises
• allows you to use the same signature for spawn and exec calls
• conveniently buffers process output, if desired

How?

Install

npm install fm-exec

Usage

var exec = require( "fm-exec" );

// Just run a binary. Returns a promise.
exec( "notepad" );

// Run a binary with arguments.
exec( "notepad", [ "foo.txt" ] );

// Buffer application output to receive it in resolution/rejection handler.
exec( "git", [ "rev-parse", "HEAD" ], {
    cwd    : applicationDirectory,
    buffer : true
} )
    .then( function echoVersion( version ) {
        console.log( version );
    } )
    .catch( function onError( error ) {
        // handle error
    } );

// Execute a command through the shell.
exec.shell( "notepad", [ "foo.txt" ] );
// When using exec.shell, this call is identical to the one above.
exec.shell( "notepad foo.txt" );
