Use Before Insert Postgres Triggers as SQL Column Presets with Hasura
Jason Brown

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.

Jason Brown

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.

Why You Should Use Hasura
Jason Brown

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
Jason Brown

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.

Multi List Drag and Drop With react-beautiful-dnd, Immer, and useReducer
Jason Brown

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.

Using react-beautiful-dnd with Next.JS
Jason Brown

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.

Using a serverless.yml config and a few environment variables you can deploy to multiple environments like staging, production, or even one off feature branches.
