Web development with Go

[Paulo Júnior]

Hi all.

I hope you are well.

What are the main use cases for traditional web applications (I mean non-SPA) development with Go? In other words, in a world of Single Page Applications (SPA) and its frameworks (such as Angular, React, Vue, so on) where does Go have space?

Best regards.
Paulo.

An important use case is when packaging your app in a container for deployment in Kubernetes or Google Cloud Run, for e.g..

Compared to an app written in Php where you have to package the framework code into the container, the same app

rewritten in Go reduces the size by a huge amount as the only thing you need to include in a scratch base image is the binary plus

some certificates.

Also, the memory requirement to run the app is much less.

One of my app's size was reduced from 600Mb(php) down to 20Mb(Go)!!

Also, memory requirement reduced from 1024Mb to 128Mb on Google Cloud Run, thus saving a lot of money!

I wouldn't put certificates into a container image either, and definitely not the related private keys.  I'd store them as kubernetes Secrets and provide them to the container that way.  It reduces the exposure of the private keys, and allows certificates to be replaced without rebuilding the image - e.g. to deploy the same container in two different places.

Of course, Brian.

I meant the CA Certificates.

Applications whether single page or multiple pages do need to communicate with some sort 

of back-end to get their data and perform business logic. They need something to serve their AJAX requests.
And Go is a useful language for writing such  back-ends.
