Why do we use Golang?

Can Golang be used for web development?
Golang helps the developer to develop highly scalable applications. Golang is a compiled language, so web applications built with Golang can run in any environment, be it in the cloud or on any operating system. Golang native web applications run on Google App Engine and Google Cloud Run.

How to use HTTP client in go to improve performance?
In this post, we will discuss how to make HTTP requests for higher performance in Go and also how to tune it. HTTP (Hyper Text Transfer Protocol) is a communication protocol that transfers data between client and server. HTTP requests are very essential to access resources from the same server or from a remote server.
How to create a local HTTP server in go?
1. Using httptest.Server: httptest.Server allows us to create a local HTTP server and listen to any requests. On startup, the server picks any available open port and uses it. So we need to get the test server URL and use it instead of the actual service URL. 2. Overriding http.Transport
