Add an option to have recordings indented by 2 spaces

[KodiVerse]

We would like to add an option to:

nock/lib/back.js

Line 176 in b687592

outputs = JSON.stringify(outputs, null, 4)

This will allow us to support specifying the indentation in our recordings.

We would be willing to do a pull request.
Suggestions for option name "indent" or "recordingIndent"?

@paulmelnikow @mastermatt We would really like to implement this. Any advice you can give before we get started?

[mastermatt]

Just to throw an idea out: What if that JSON.stringify line was updated to only be called if output wasn't already a string? Then the expectation would be that users could define a afterRecord hook if they wanted to deviated from the out of the box option.
Or.. we could implement both.

@simlu as for advice on implementing the option; the options arg passed to Back is already made available in the finish function. It should be as basic as looking for a specific key in that object.
Things to keep in mind, the space arg of stringify can be a number, string, or null.

I actually like option one as it would give much more flexibility e.g. use https://github.com/lydell/json-stringify-pretty-compact

Was this solved in #1649?

@paulmelnikow Yes, once that is merged in we should be g2g. Thank you!

Thank you very much. We've already made use of this new feature here
