Limit request total timeout to just 2000ms with Req
How do we limit a Req.post! or Req.get! to a total timeout of just 2000ms?
I have an integration that needs very timely responses.
Limiting external API requests to just 2000ms would help my integration scenario.
I have looked at the documentation, but I’m not getting it at all.
As usual, AI suggestions are no use either.
suggested code - Via WhatsApp Meta AI Llama 3.2
def test do
Req.get!("https://api.github.com/repos/wojtekmach/req",
finch: [
options: [
timeout: 2000,
receive_timeout: 2000
]
]
)
end

I think the Finch option you want is :request_timeout:
The amount of time to wait for a complete response before returning an error. This timeout only applies to HTTP/1, and its current implementation is a best effort timeout, it does not guarantee the call will return precisely when the time has elapsed. Default value is
:infinity.
And if you’re using HTTP/2 then that won’t work.
And the syntax to set the various timeouts looks like:
Req.get("https://httpbin.org", connect_options: [timeout: 500], receive_timeout: 2000, pool_timeout: 500)
The main place to see those options is at: Req — req v0.6.2
But I’m pretty sure those various timeouts all stack so if you want to limit the total time I agree with @hilko that a Task is your best bet.

Could it work to just spawn a task that just times out after that amount of time?

I added retry: false as well, so far the receive_timeout: 2000 seems okay
