SSH Tunneling

Problem

You want to query a DB and get a result set, but you don't have access to that DB directly from your localhost.

• Bad solution A: Cry
• Bad solution B: Ask someone who does have access to run your query for you
• Bad solution C: ssh into a box that has access, then psql into the DB

A top-level App component returns <Button /> from its render() method.

1. What is the relationship between <Button /> and this in that Button’s render()?

2. Does rendering <Button><Icon /></Button> guarantee that an Icon mounts?

3. Can the App change anything in the Button output? What and how?
