How to make Node pm2 log to console?

Spread the love

To make Node pm2 log to console, we call connect.

For instance, we write

const pm2 = require("pm2");

pm2.connect((err) => {
  if (err) {
    console.error(err);
    process.exit(2);
  }
  pm2.start(
    [
      {
        script: "server.js",
        output: "/dev/stdout",
        error: "/dev/stderr",
      },
    ],
    (err, proc) => {
      if (err) {
        throw err;
      }
    }
  );
});

to call connect with a callback that calls start with some options.

We set output to the location to '/dev/stdout' to log to the console.

And we log errors to '/dev/stderr' by setting error to "/dev/stderr".
