API World + AI DevWorld 2022

In this talk we will showcase how to leverage the power of The Graph to index blockchain event data into an easy to use and flexible API built on Graph QL.

Attendees can easily follow along the workshop by building out their own development environment with only Git, Yarn and NodeJS. Come learn to build the future on Web3. 

With the expansion of the cloud towards the end user, some common issues emerge: unreliable internet connection, fewer hardware resources, unreliable power available, metered connection …
In most of those use cases though the devices out there still need some way to communicate with the cloud, to let it know they are still alive at the very least. But what is the quickest and most efficient way to do that?
In this session we will explore and compare different API protocols in terms of resource usage and we will examine different mechanisms that are usually available at the API gateway level and at the device level, to optimize communication and respond to failures at the different levels of the stack.
We will conclude with some industry best practices when building services at the edge. 

Customer-facing applications are increasingly integrated across the business, driven by a host of workflows spanning departments and even organizations. From marketing to e-commerce and all the way into the heart of product, content is powering all of our customer interactions, yet it is so often treated as an afterthought, handled by an amalgam of disconnected databases, isolated systems and, god forbid, a patchwork of spreadsheets.

There is a better way. In this talk, I'll outline how to build a modern, scalable content infrastructure, then walk you through the important steps you need to take to build that resilient, collaborative, global content store. I'll introduce the concept of a “Content Lake", similar to a data lake, and discuss the specifics of the Sanity Content Lake, a turn-key system for content orchestration that provides a single source of truth. We also invented GROQ, a flexible query for schemaless JSON documents, that's used to power GraphQL and other APIs. This lets you integrate content across internal tools and systems so applications run smoothly with the right content at the right time. 

BL is an open-source, high-productivity, fourth generation (4GL), DDD/BDD focused, programming language that transpiles into mainstream programming languages such as TypeScript and Java and helps developers build and maintain complex APIs faster and better than ever before.

Domain Driven Design (DDD) and Behavior Driven Development (BDD) are proven ways to increase developer productivity and a sure way to improve the probability of a product or project succeeding. Nonetheless, DDD and BDD require significant experience and have a very steep learning curve. As a result, most organizations and individuals fail to make DDD and BDD part of their everyday routine and end up missing out on their significant advantages.

BL has been created to dramatically reduce the DDD/BDD learning curve for developers, allowing them to produce working DDD systems in no time.

During the talk we will see how we can quickly write a working system using Domain-Driven Design and deploy it as a TypeScript project while easily switching between a modular monolith and an Event-Driven distributed microservices architecture.
