Problem starting a CompoundJS App

[leandono]

Hi,
For some reason, when i want run a app created with CompoundJS with pm2, the aplication doesn't start (but in other ways, like node server.js, using nodemon or forever, the problem doesn't happen).
The script server.js is generic (automatically created by Compound):

#!/usr/bin/env node

/**
 * Server module exports method returning new instance of app.
 *
 * @param {Object} params - compound/express webserver initialization params.
 * @returns CompoundJS powered express webserver
 */
var app = module.exports = function getServerInstance(params) {
    params = params || {};
    // specify current dir as default root of server
    params.root = params.root || __dirname;
    return require('compound').createServer(params);
};

if (!module.parent) {
    var port = process.env.PORT || 3000;
    var host = process.env.HOST || '0.0.0.0';

    var server = app();
    server.listen(port, host, function () {
        console.log(
            'Compound server listening on %s:%d within %s environment',
            host, port, server.set('env')
        );
    });
}

And the console don't show any problem:

$ pm2 start server.js -v
⌬ PM2 Configuration :  { script: 'server.js', name: 'server' }
⌬ PM2 You can write the current configuration by adding -w option
{ script: 'server.js',
  name: 'server',
  pm_exec_path: '<path>/server.js' }
⌬ PM2 Process launched

Any idea? Specifically i don't know if this a problem with compoundjs or with pm2.

Best regards

Yes it doesn't work because in the server.js CompoundJS use module.parent, and as pm2 wrap the code in child process the code is not executed.

To fix it :

#!/usr/bin/env node

/**
 * Server module exports method returning new instance of app.
 *
 * @param {Object} params - compound/express webserver initialization params.
 * @returns CompoundJS powered express webserver
 */
var app = module.exports = function getServerInstance(params) {
    params = params || {};
    // specify current dir as default root of server
    params.root = params.root || __dirname;
    return require('compound').createServer(params);
};

//if (!module.parent) {
    var port = process.env.PORT || 3000;
    var host = process.env.HOST || '0.0.0.0';

    var server = app();
    server.listen(port, host, function () {
        console.log(
            'Compound server listening on %s:%d within %s environment',
            host, port, server.set('env')
        );
    });
//}
