Look-alike nodejs 6.x child_process.fork() function module for nodejs 4.x
- Instead of using the stdin channel for communicating with the child process (nodejs 6.x), node-fork is using a totally separated new pipe channel.
- Its is not possible to send a handle with the send() function as can be done with nodejs 6.x. (pull request implementing this is much appreciated!!)
node-fork can be installed from NPM with:
npm install node-fork
The code almost speaks for itself: see the example directory!!
Parent code example:
var path = require('path'),
inspect = require('util').inspect,
fork = require('fork');
var child;
try {
child = fork.fork(path.join(__dirname, 'child.js'));
} catch (err) {
console.log('Error forking child: ', inspect(err));
process.exit(1);
}
child.on('message', function(msg) {
if (msg.stop) process.exit(0);
console.log('The child says: ', msg.hello);
});
child.send('This is your parent!');Child code example (child.js):
var fork = require('fork'),
inspect = require('util').inspect;
try {
fork.forkChild();
} catch (err) {
console.log('Error initializing parent comms:', inspect(err));
process.exit(1);
}
process.on('message', function(msg) {
console.log('The parent says: ', msg);
process.nextTick(function() {
process.exit(0);
});
});
process.send({ hello: 'I am alive!'});To build node-fork and run the tests after checking it out:
make test
