Configuring Couchbase Server and Couchbase Sync Gateway

Question

I am successfully connecting my couchbase server with my application using localhost:3000

var express = require('express');
var bodyParser = require("body-parser");
var couchbase =require("couchbase");
var request = require("request");

var app = express();
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended:true}));


var cluster = new couchbase.Cluster('couchbase://localhost'); 
cluster.authenticate('Administrator', 'ABcd1234'); 
var bucket = cluster.openBucket('non-med'); //the name of bucket is 'example'
bucket.on('error', function(err) { console.log('Bucket: CONNECT ERROR:', err);}); 

module.exports.bucket = bucket;

var routes = require("./routes.js")(app);

var server = app.listen(3000, function(){
    console.log("Listening on  port%s...", server.address().port); 
});

I have also downloaded Couchbase Sync Gateway from on my mac in commend line and service is loaded shown as follows

sudo ./sync_gateway_service_install.sh
chown: sync_gateway: illegal user name
chown: sync_gateway: illegal user name
/Library/LaunchDaemons/com.couchbase.mobile.sync_gateway.plist: service already loaded

Could everyone tell you how can i configure the Conuchbase Sync Gateway in detail??

Any amendment on the app.js
Is there any new file needed to create e.g. sync-gateway-config.json? If so,
(2a)Where do i include this file? My application project folder?
(2b)May i know the format of json?

Thanks

Sync gateway needs to run as a separate file.You can set set syncing criteria by creating channels in http://localhost:4985/_admin/. You can refer https://developer.couchbase.com/documentation/mobile/current/installation/sync-gateway/index.html to run the sync-gateway. I'll attach a sample sync-gateway configuration file below. Cheers!!

{
    "log": [
        "HTTP+"
    ],
    "adminInterface": "localhost:4985",     //Public port
    "interface": "localhost:4984",       //Admin port
    "databases": {
        "your_cluster_name": {          //add your couchbase cluster name
            "server": "http://localhost:8091",  //add couchbase server url
            "username": "your_username",
            "password": "your_password",
            "bucket": "your_bucket_name",
            "users": {
                "GUEST": {
                    "disabled": true
                },
                "admin": {
                    "admin_channels": ["*"],  //give permission to all the channels
                    "password": "123456"   //admin channel password
                }
            },
            "import_docs": "continuous",
            "enable_shared_bucket_access": true,
            "sync":`
           function(doc) {
                channel(filter); // set your filtering criteria          
            }`
        }
    }
}
