how to set timeout from frontend in apigClient aws

问题

I'm working with the amazon api client gateway.it works fine with all the request and response. Now I want to add some timeout, I tried this:

---

        apigClient.method(params, body, additionalParams)
        .timeout(1000)
        .then(function (result) {
            //succcess part
        }).catch(function (err) {
            //error part
    });`

---

But It doest work. I got this message from my console "error: apigClient.method(...).timeout is not a function"

The generated JS client doesn't support custom timeout by default, but you can add your own timeout logic on top of the client with very minimal modification since the underlying HTTP client is supporting client side timeout in the request object.

Suggested modification

I called to AWS support and I got this answer:

Hello, Thanks for taking the timeout to chat with us!

Here's a summary of our chat: You are looking fr a way to set timeouts while making requests to API gateway >from your apigClient SDK. Setting timeouts in API Gateway is not possible as API >Gateway has a hard limit of 30 seconds as a timeout for any type of integration. >For details on this, please refer: http://docs.aws.amazon.com/apigateway/latest/developerguide/limits.html

However, automatic retries are implemented from the SDKs. For details on the >retry logic with exponential backoffs, please refer to the documentation: http://docs.aws.amazon.com/general/latest/gr/api-retries.html

Please get back to me if you have any questions and I'd be happy to assist you.

I hope this helps!!!
