login command

[rufuspollock]

data login logs you in with a simple experience using your existing social login.

Acceptance criteria

• data login results in a token in your config file that you can use for further interaction with the API system
• data login uses an existing social provider (e.g. Google) in browser to do login with a very easy experience

Tasks

• Interaction with conductor to get login url
• Open login url and handle response
• Store token on success
• Retrieve profile
• Handle failure - simple classic try/except in bin/data-login.js (copy data-push.js)
• Help info
• (More) Tests for this

Analysis

• (with conductor): check authorised, e.g. https://conductor/check?next=http://localhost:5432
• (conductor sends back): nope, here’s the google login url:
• Locally, start an http server listening on port 3000
• Locally, open a browser with that google login URL
• User authenticates with provider (i.e. Google/Github/...)
• If successfull authentication
  • gets redirected to http://localhost:3000?jwt=
  • Client stores the token and can return instructions to close window (or even just a <script>window.close();</script> response to close the browser window)
  • (optional) Client now uses the token to retrieve user profile (name, email etc.)
  • Client can now inform the user login was successful and go on with what it wanted to do.
• If unsuccessful
  • gets redirected to http://localhost:3000 (no token)
  • Client returns a <script>window.close();</script> response to close the browser window
  • Client informs the user login had failed
