Why would anyone build with this?

REASON 1

Deploy Go functions on Google Cloud Functions without managing servers.

REASON 2

Write an event-triggered function, like resizing images on upload, entirely in Go.

REASON 3

Build HTTP-triggered serverless endpoints using Go instead of switching languages.

Wtf does this do

This repository provides support for running code written in the Go programming language on Google Cloud Functions. Google Cloud Functions is a service that lets you run small pieces of code in response to events, like a file being uploaded or an HTTP request coming in, without managing any servers. This package acts as a bridge so that Go code can run smoothly on that platform. At a technical level, the package provides the underlying plumbing needed for Go programs to communicate with Google's infrastructure. When you write a function, you need a way for Google's system to start your code, pass it the incoming data, and return a response. This project handles that behind-the-scenes wiring. The README itself doesn't go into detail about specific features or internal mechanics, but its existence as a dedicated support package signals that it handles the integration work between Go and Google's environment. This would be used by developers building serverless applications on Google Cloud who want to write their logic in Go. For example, if a startup builds a feature that automatically resizes images whenever a user uploads one to cloud storage, they could write that resizing logic in Go and deploy it as a cloud function. Before support packages like this existed, developers would have had to use other languages or find workarounds. With this, they can stick with Go end-to-end. Given the low star count and very brief README, this appears to be either an early or minimal project, or possibly a piece of infrastructure that has since been folded into Google's official tooling. The project is written in Go, which makes sense given that its entire purpose is to support Go code running on Google's platform. The README doesn't document additional tradeoffs or design decisions, so it's best understood as a focused utility serving a narrow but important integration need.
