pm2-service-discovery

Synchronize services from consul to nodejs app managed by PM2.

How it works

This module propagate services changes using an event bus to services managed by PM2.

The module send config update to application :

• Pragmatically when
  • PM2 start
  • PM2 launch a new service
  • Consul have a new configuration
• Manually : pm2 trigger pm2-microservice reload

Sample

When the module is installed... in you code managed by pm2 :

process.on('message', (rs, err) => {
  if(err) return;
  if(rs && rs.topic === 'service:update') {
    const services = rs.data || [];

    console.log(JSON.stringify(services, null, 4));
  }
});
