Executes shell commands synchronously.
Does not work on Windows
Simplifies build scripts.
Express 3 has asynchronous templates and helper functions are synchronous. Some of my helper functions invoke compilers with async interfaces. I use this library in DEVELOPMENT mode to precompile files on the fly through the command line.
NOT RECOMMENDED on production servers.
npm install execSync
Require it
var execSync = require('execSync');
Execute shell commands. exec interlaces stdout and stderr to result.stdout.
var result = execSync.exec('echo $USER; echo some_err 1>&2; exit 1');
console.log('return code ' + result.code);
console.log('stdout + stderr ' + result.stdout);
Capture STDOUT
var user = execSync.stdout('echo $USER');
console.log('Hello ' + user);
Get result code
var code = execSync.code('echo $HOME');
console.log('result ' + code);
