newrelic.js config validator

Is your feature request related to a problem? Please describe.

Yes. I added the expected_status_codes property to my project config but didn’t realise it was wrapped in the error_collector object. Took a while to get to the bottom of the problem. Having a little script that can validate the config file and point out errors would be really handy.

Feature Description

A script that the user can run to validate the newrelic.js config file. For example:

$ npx newrelic-validate-config
Found 3 issues:
1. Unexpected property `expected_status_codes`. Did you mean `error_collector.expected_status_codes`?

2. Invalid type given for `app_name` should be `array` found `string`

3. Invalid value given for `logging.level` found "errror" should be one of: "fatal", "error", "warn", "info", "debug" or "trace"

Additional context

I’m happy to contribute to the solution, just wanted to get an idea if people would find this useful or not?

That would be a pretty sweet feature @davidnormo – I know I would have liked something similar when I was starting with the Node Agent, and I can think of a bunch of support tickets where having such a thing would have helped.

Do you think you’d use something formal like JSON Schema for this? Or something a bit simpler with a set of type rules for each “path” into the JSON file? Or some third thing?

@davidnormo is this something you are still working on? If not, we will close this out.
