Executing parallel and async client requests

Performing client requests in parallel is relatively simple in Go. In the following recipe, we'll use a client to retrieve multiple URLs using Go buffered channels. Responses and errors will both go to a separate channel that is readily accessible by anyone with access to the client.

In the case of this recipe, creating the client, reading the channels, and handling responses and errors will all be done in the main.go file.

How to do it...

These steps cover writing and running of your application:

2. Run the following command:

          $ go mod init github.com/PacktPublishing/Go-Programming-Cookbook-Second-Edition/chapter7/async

        

You should see a file calledgo.modcontaining...
