Use React Native Reanimated and useEffect to create expanding rings. We'll leverage useSharedValue, useAnimatedStyle, withDelay, withRepeat, and use interpolation to achieve our animated expanding ring effect.

Column Presets sometimes aren't enough in Hasura. We will create a Postgres trigger function that can use hasura session variables to run SQL queries. Combined with BEFORE INSERT triggers we can effectively use SQL queries for column presets.

Hasura provides the ability to schedule HTTP events to be fired at a given date and time. We will use the /v1/query endpoint and the comment section to allow for cancelling events with an id that we create.

We'll create a task system with permissions, unread task filtering and assigned task filtering all without a single line of code. Walking through the Hasura console creating the tables, relationships, and finally leveraging Hasura and its role based access control. We'll finish by showing off the GraphQL queries and mutations that you would use in your application.

PostGIS makes querying by latitude and longitude easy. With Hasura's first class support for PostGIS we can add GIS abilities to GraphQL and make querying for data by location possible.

Hasura is an incredible new tool that offers an easier way to build an app faster and securely with flexibility when you need it. Including database migrations, websocket real time data, role base access controls, schedule events, cron jobs, and more.

It has become a swiss army knife of tooling with just the right amount of configuration, and escape hatches when you need to execute your own business logic.

Getting started with Hasura locally on your development machine can be accomplished in a few short minutes. It requires Docker, the Hasura CLI, and a docker-compose.yaml file provided by Hasura.

A few commands later and you have a full fledged GraphQL engine running connected to a Postgres database.

We'll examine how we can use Emotion, Tailwind and Babel to build out string validated Tailwind classes but leverage the power of Emotion.

Getting setup with drag and drop can be complicated, especially with multiple lists. We'll explore how to use react-beautiful-dnd to create multi-list drag and drops. We'll also use Immer and useReducer to create immutable data structures to simplify and improve the performance of our code.

The defacto standard for drag and drop in React is react-beautiful-dnd, however there are some caveats when it comes to using with a server side rendering library like Next.js. One call to resetServerContext in the custom _document will take care of all the issues.
