Title
Body
In node.js vm module , i can execute some javascript in another node.js process. What i want to achieve is being able to catch logs performed in the script runned by the vm. For example i want to catch the "foobar" log: var vm = require('vm') vm.runInThisContext('console.log("foobar");', 'myfile.vm'); // how can i get the "foobar" log? Thanks in advance EDIT: The answer below works well, although there's a shorter version: function captureStdout(callback) { var output = '', old_write = process.stdout.write // start capture process.stdout.write = function(str, encoding, fd) { output += str } callback() // end capture process.stdout.write = old_write return output }
