This was originally written for a Remix app, but you could adapt it to work for any SSR framework.

It's configured to use MySQL on Planetscale, but you could adjust it to use Postgres or SQLite if you want.

// Our encouraged use of suspense in Apollo will comprise of 2 hooks: useBackgroundQuery and useReadQuery (final names TBD).
// Using these 2 together encourage the use of the render-as-you-fetch pattern to start fetching as soon as possible: 
// https://17.reactjs.org/docs/concurrent-mode-suspense.html#approach-3-render-as-you-fetch-using-suspense

const Parent = () => {
  // This hook provides no access to data. It's meant purely as a fetching mechanism
  const { promise } = useBackgroundQuery(QUERY);

  return (

Remix Deferred

Remix Deferred is currently implemented on top of React's Suspense model but is not limited to React. This will be a quick dive into how "promise over the wire" is accomplished.

SSR + Hydration

It isn't rocket science, but a quick recap of how frameworks such as react do SSR:

1. Load data
2. Render the app

Python

This is my recommended Python setup, as of Fall 2022. The Python landscape can be a confusing mess of overlapping tools that sometimes don't work well together. This is an effort to standardize our approach and environments.

the result of each intermediate step is stored (so errors can be retried)
at the end of the pipeline data is put into a document store
optionally, event handlers can listen to create/update/delete events and fan data out to other systems
