How do I use pm2.start()?

Question

It's my first time with pm2. I am particularly trying to use the programmatic API. Now when I call pm2.start('./app.js'), it doesn't look like the script is executed. In the sample code below, I expect to see "Working" in the console.

app.js

console.log('Working');

index.js

pm2.connect((err) => {
    pm2.start('./app.js', (err, d) => {
    });
});

Am I missing something?

Your code is correct only. PM2 write logs in file instead of console . So You can find logs in app-error.log file or app-out.log file.

var pm2 = require('pm2')

pm2.connect((err) => {
    if(err){
        console.log('ERROR ',err)
    }
    pm2.start('./app.js', (err, d) => {
        console.log('APP STARTED', err, d)
    });
});

You can find the log file path in the console.log('APP STARTED', err, d) output.
