I'm using child process fork but I'm not able to pipe child console logs to parent's dev tools

[nagraj...@gmail.com]

This is my code:

1. index.html:

            var childprocess = nw.require('child_process');

            var worker = childprocess.fork('worker.js', [], {silent:true});

            worker.stdout.on('data', function(data) { console.log(String(data)); });

            worker.stderr.on('data', function(data) { console.error(String(data)); });

            worker.on('error', function(err) { console.error(err); });

            worker.on('message',function(msg){console.log(msg)});

2. worker.js:

        process.send("woah");

        process.send('starting child process');

        process.stdout.write("tuntak");

        process.send('starting child process');

        console.log("ha ha");

        process.on('message', function (m) {

            console.log('received message from parent: ');

            process.send(m);  

        });

The output I get on console is :

All I want is the console log to appear in dev tools.

I looked up here : https://nodejs.org/api/child_process.html#child_process_options_stdio

It says to use pipe,I've tried using pipe,inherit and other combination like:

1)child = child_process.fork('./cp.js', {stdio: ['pipe','pipe','pipe']}); child.stdio output is [null,null,null,null] 2)child = child_process.fork('./cp.js', {stdio: ['inherit','inherit','inherit']});

child.stdio output is [null,null,null,null]

3)child = child_process.fork('./cp.js', {

    stdio: [

      0, // Use parents stdin for child

      'pipe', // Pipe child's stdout to parent

      fs.openSync('err.out', 'w') // Direct child's stderr to a file

    ]

});

child.stdio output is [null,null,null,null]. Please point out if something is wrong here.

hi,

i want to get console.log from child process of seperated node app.

and i faced to same problem like you, even i used the latest nwjs version v0.18.4 on window.

only stdio was set to Socket, when {silent:true}. but no different between using pipe and inherit.

did you solve this problem?
