How are errors handled?

[rosskukulinski]

I would expect the callback function passed to ld_client.get_flag() would follow the standard nodejs (err, data...) pattern. Skimming the code, it looks like on HTTP error you simply use the default value. That won't tell me if your service is having issues or if I've supplied invalid credentials.

That is an good point-- we will change the callback. The Go client does a much better job of this, and the nodejs idiom seems quite appropriate here.

Adding to this, it would be great if line 82 became cb(error, default_val);, and line 81 and line 143 were suppress(ed/ible).

Switching to an error-first callback will require a new major version release, since it's an API-breaking change. The logging suppression can happen in a minor release-- which will likely go out tomorrow.

This is now in PR. As I mentioned, it'll be a major version release since it's an API breaking change. If you bump to this version and don't update your toggle calls everywhere, feature flags will behave very badly, indeed-- so be cautious when upgrading to this version.

I've released this in version 1.0.0. Docs and quickstart are being updated too.

Just to reiterate-- be sure to update your toggle calls when you bump to this version!
