Hey @olxandr ! A very well drafted PR. I would like you to also add docs with a docker container and a small code snippet. Refer how it is added for the others.

Other than that I would want you to also add screenshots of...... Logs Traces and metrics for a Db call. Would then test it in local and we will be good to go.

a docker container

What surprised me is that in order to get the Couchbase ready to use, just spinning up the docker container isn't enough. You also need to go to Couchbase Web Console by visiting http://localhost:8091 and manually setup the cluster. Here is the source.
Should i add this info somwhere too?

Hey @olxandr !

A bit of info on the datasource setup in the docs would be appreciated.

Sure, here are the screenshots:

Trace:

Error: pkg/gofr/container/mock_container.go:51:6: Function 'NewMockContainer' has too many statements (51 > 50) (funlen)

Not sure what i'm supposed to do with this failed check.

@olxandr Please resolve the linter issues in your PR. Thankyou!

[olxandr]

The NewMockContainer() inside pkg/gofr/container/mock_container.go has too many statements after adding Couchbase. So like i said:

Not sure what i'm supposed to do with this failed check.

Any suggestions on how to deal with it?
One approach is to breakdown the function into smaller, more focused helper functions. It is also possible to increase the funlen linter limit.

This PR looks good to me.
