Without Restart Dynamically enable/disable debug in runtime via API [NOT IDEAL if u running pm2 cluster mode]

debug-runtime-dynamic-example.js

const debug = require('debug');
const log = debug('namespace1')

const express = require('express');

const app = express();
app.get('/', (req, res) => {
    log('Homepage loading')
    res.json({ title: 'Homepage' });
})


app.get('/enable', (req, res) => {
    if(!req.query.tag) return res.json({
        message: 'req.query.tag missing'
    })
    
    // - Enable Debug Namespace
    debug.enable(req.query.tag);
    log(`Enabled debug namespace: ${req.query.tag} in runtime`).
    
    res.json({
      status: debug.enabled(req.query.tag)
    })
})

app.get('/disable', (req, res) => {
    log('Disabling debug dynamically in runtime').
    debug.disable();

    res.json({ status: debug.enabled(req.query.tag || '*') })
})


app.listen(8090, () => {
    console.log('express listeing at http://localhost:8090')
})

@yogesum flagr solution looks like solving the issue of

1. PM2 Cluster or Nodejs Cluster
2. Multiple Physical app servers behind load balancer
