Axios

[glynnbird]

Overview

The request module is deprecated. This pull request will aim to replace request with axios. I tried to do this work inside of the "relax" function so that all the callers of the relax function stay the same. Only the db.copy had to be removed because the COPY method is not supported by axios.

As this project's dependency "cloudant-follow" is also a user of request (and is becoming deprecated itself), the 'follow*' functions of this library are also deprecated and replaced with new 'changesReader' functions which I wrote myself and have plumbed into the library.

I also took the opportunity of removing extraneous dependencies (Nano now only has 2 dependencies), fixed up the logging module and improved the README.

Note it looks like a lot of commits, but the first bunch are from a previous branch that were 'squashed' into master. All of this change will get squashed when merged.

Hi, how is the status of this branch? I've run my tests against it and noticed that errors aren't forwarded from CouchDB as they have been before. For example, the response for db.get on a deleted document used to include:

  name: 'Error',
  error: 'not_found',
  reason: 'deleted',

but that's currently missing.

@LyteFM Good point. I've added quick change to ensure that the Error object thrown during errors contains attributes received in the response.

Great, works for me now - but the error response for HEAD doesn't seem to be as expected.

[glynnbird]

Thanks @LyteFM. Another commit (or two) to correct what happens when there is no response body (as with a HEAD /db/id request).

I have been waiting for this PR to be merged/released, to consume nano in my projects. Any updates on this PR?

This is a massive effort. Great work Glynn.

Just some extra housekeeping because of the master/main switchover.
