How to update load balance ?

[MrSpark2591]

I am trying to update load balance for this code. here i have loadBalancing map which is something like :
loadBalancingMap = { serviceName : [url1,url2] }
and i am using it o register service and balancer like this :
proxy .all('/'.concat(serviceName).concat('/*')) .balance(loadBalancingMap[serviceName])

now how can i update balance for this service when there is one more instance of service or some instance failed.

You can simply call .balance() method again.

@h2non yes, I thought that and tried. this is what I have done.here what I am doing is reassigning the whole thing by calling this function whenever my 'loadBalancingMap' value change. can you tell me what I am doing wrong? I know it's just silly thing but I am really not getting how to overcome.

var regeisterProxyRoute = function(serviceName){
     proxy
    .all('/'.concat(serviceName).concat('/*'))
    .balance(loadBalancingMap[serviceName])
};

You have to store the route object reference you're implicitly creating via: proxy.all('/'.concat(serviceName).concat('/*')).

So your code might look like:

var routes = {}

var registerProxyRoute = function (serviceName) {
    const path = '/'.concat(serviceName).concat('/*')
    const route = routes[path] = routes[path] || proxy.all(path)    
    route.balance(loadBalancingMap[serviceName])
}
