Strategy when a request fails or loads slowly

[writingdeveloper]

I request data from the API server. However, this API server sometimes throws a connection wait exceeded error.

I tested API server for 24hours and results are on below image. It shows It can access 67%~78% success range.

It means when I request API 10 times, it only returns data 6~7 times.

I cannot control API server so I have to make strategy that when server cannot access to API server, is there any strategies to handle this problem?

I found Retry API, and it seems that this API are suitable in my case.

I want to make it like this.

1. Request to API server
2. If it's not loaded 3 seconds after the request, how to request it additionally?

You can set a timeout option. If it fails to load in X seconds, it will simply make a new retry unless the retry limit has been reached or the request is unsafe to retry.
