How to use

Create app

const ChangeNodesApp = require('@chronotech/laborx.listeners.change.nodes');
/**
* @type app {express}
*/
const app = new ChangeNodesApp(
    express(), // express lib
    ApplicationStateService, // microservice ApplicationStateService instance
    config, // your microservice config, see below
    mongoose, // initialized mongoose instance
    [blockchainName1, blockchainName2], // array of microservice listening blockchains (etherium, binance, polygon, tron)
    new MyLogger() // any logger instance
);
app.createRoutes();

GET /nodes/get - returns current nodes config

POST /nodes/change - validate and persist new nodes config

            "isActive": 1
        }
