Getting started

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

-E: will describe the underlaying queries of the \ commands (cool for learning!)
-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

Filter Queries - Example Use Cases

Here are a few example use cases, these use cases combine filter with other parameters to make useful API queries. The syntax for any of this may change between now, implementation, and release - they're meant as illustrative examples :)

Fetch 3 posts with tags which match 'photo' or 'video' and aren't the post with id 5.

api.posts.browse({filter: "tags:[photo, video] + id:-5", limit="3"});

GET /api/posts?filter=tags%3A%5Bphoto%2Cvideo%5D%2Bid%3A-5&limit=3

Tether Drop + React Portal + Redux

This is an example of using Tether Drop with React Portal (and Redux for managing the state). I was asked if using React Portal is redundant, as both libraries pull the content into the <body>. Using only Drop would cause an invariant violation in React becuase of the DOM mutation, so I'm using React Portal to first bring it outside without React complaining (I don't know how React Portal does it, I haven't checked out the source, but it works). Once it's out of React's supervision, I can apply Drop to it.

Dropdown.jsx is the actual dropdown component
App.jsx is just an demo that uses it

This is my lazy way out of this limitation using an existing library that has much more features than you need, but chances are that you're going to need a library like React Portal anyway for stuff like modals.
