Reconnect Strategy

[sachin-kiwi]

Hi,
While working with the library I faced the issue
NotConnectedError: connect ECONNREFUSED 35.85.20.122:51233 at Connection.onConnectionFailed

I found that there can be a few reasons.

1. Server decided I am allocated extra resources so it disconnect
2. I have a bad connection
3. server has restarted due to some reason

Then I look into handling the such a situation and found this by xrpl
#1101

Now, I am trying to implement a connection strategy to handle this scenario in production.

Can you give me some insight on reconnect method in xrpl.Client?

@sachin-kiwi Can you attach an error listener to the client and then see what error it's returning?

For example:

client.on('error', (error) => { /* code here to detect what type of disconnect error */ }

Also adding a listener for reconnect and disconnect.

@khancode
how many times reconnect is done.I tested it and it attempted 2times only.

@khancode how many times reconnect is done.I tested it and it attempted 2times only.

@sachin-kiwi There's no limit on reconnect attempts. Were you able to output the error type using an error listener?

[sachin-kiwi]

'reconnect',
'getaddrinfo EAI_AGAIN s.devnet.rippletest.net',NotConnectedError: getaddrinfo EAI_AGAIN s.devnet.rippletest.net
at Connection.onConnectionFailed (/home/kiwitech/blockchain/circuitbreaker2/node_modules/xrpl/dist/npm/client/connection.js:338:54)

Sample to reproduce

client.on('error',(...parameters)=> {
console.log(parameters);
if (parameters.includes('reconnect')){
console.log(XRPL_CLIENT)
}
});

@khancode
Using client.on('error', (error) => {}
it only gives event name

For me output

reconnect

Note: It is attempting only 2 times only.I checked

I am using defaut config for xrpl connection in devnet network

How to control num of attempts for reconnect manually.

@sachin-kiwi can you provide your code so I can reproduce the issue?
