How to Convert Crypto Currencies with Microservices in Node.js and GRPC

Have you ever struggled with designing and structuring your Node.js applications? Building applications that are well organised, testable and extendable is not always easy. It can often turn out to be a lot more complicated than you expect it to be. In this live event Matteo will show you how he builds Node.js applications from scratch. You’ll learn how he approaches application design, and the philosophies that he applies to create modular, maintainable and effective applications.

Platformatic allows you to rapidly develop GraphQL and REST APIs with minimal effort. The best part is that it also allows you to unleash the full potential of Node.js and Fastify whenever you need to. You can fully customise a Platformatic application by writing your own additional features and plugins. In the workshop, we’ll cover both our Open Source modules and our Cloud offering:- Platformatic OSS (open-source software) — Tools and libraries for rapidly building robust applications with Node.js (https://oss.platformatic.dev/).- Platformatic Cloud (currently in beta) — Our hosting platform that includes features such as preview apps, built-in metrics and integration with your Git flow (https://platformatic.dev/). 
In this workshop you'll learn how to develop APIs with Fastify and deploy them to the Platformatic Cloud.

Passwordless authentication may seem complex, but it is simple to add it to any app using the right tool.
We will enhance a full-stack JS application (Node.JS backend + React frontend) to authenticate users with OAuth (social login) and One Time Passwords (email), including:- User authentication - Managing user interactions, returning session / refresh JWTs- Session management and validation - Storing the session for subsequent client requests, validating / refreshing sessions
At the end of the workshop, we will also touch on another approach to code authentication using frontend Descope Flows (drag-and-drop workflows), while keeping only session validation in the backend. With this, we will also show how easy it is to enable biometrics and other passwordless authentication methods.

Deno 1.9 introduced a new web server API that takes advantage of Hyper, a fast and correct HTTP implementation for Rust. Using this API instead of the std/http implementation increases performance and provides support for HTTP2. In this workshop, learn how to create a web server utilizing Hyper under the hood and boost the performance for your web apps.

The workshop focuses on concepts, algorithms, and practices to decompose a monolithic application into GRPC microservices. It overviews architecture principles, design patterns, and technologies used to build microservices. It covers the theory of the GRPC framework and protocol buffers mechanism, as well as techniques and specifics of building isolated TypeScript services in the Node.js stack. The workshop includes a live use case demo of decomposing an API application into a set of microservices. It fits the best architects, tech leads, and developers who want to learn microservices patterns.

Deploying decoupled and microservice applications isn't just a problem to be solved on migration day. Moving forward with these architectures depends completely on what your team's workflow experience will look like day-to-day post-migration.
The hardest part of this can often be the number of vendors involved. Some targets are best suited for specific frontend frameworks, while others are more so for CMSs and custom APIs. Unfortunately their assumptions, workflows, APIs, and notions of security can be quite different. While there are certain advantages to relying on a strict contract between apps – where backend and frontend teams work is limited to a single vendor – this isn't always realistic. This could be because you're still experimenting, or simply the size of your organization doesn't allow for this kind of specialization just yet.
In this workshop, you'll have a chance to explore a different, single vendor approach to microservices using Strapi and Next.js as an example. You'll deploy each app individually, establishing a workflow from the start that simplifies customization, introducing new features, investigating performance issues, and even framework interchangeability from the start.
